2021 to 2022 winter forecast washington state

The following video highlights from NOAA's 2021-2022 Winter Outlook that provide seasonal predictions for temperature, precipitation, and drought. Here is a brief summary of their outlooks: Several of these forecasters agree that winter will start fast with cold, snowy conditions before trending milder. Imagine ENSO as a person riding astationaryexercise bike in the middle of a stage all day long. Winter Weather Safety. Finally, precipitation will be near normal nationwide in March, the Farmers Almanac offered in a qualifier, noting that in a sense, March will be a microcosm of the entire winter., From start to finish, the month will be full of stretches of uneventful weather, but when it turns stormy, the precipitation will come in big doses, the publication said. I am also looking at the north Pacific, just south of Alaska. The price of natural gas sold to Nevada ratepayers saw another unusually high spike in January 2023, hitting $36.81 per thousand cubic feet, up from $3.74 in January of 2021 and $7.45 in January 2022. This failure of the typical pattern occurs because La Nia is never the only thing that influences the climate over the United States during the winter. Spokane hasn't seen one since 2017. Below are some, though not all, of the factors that we considered in determining conditions for this upcoming winter. All right. J. Atmos. 2000, Cassou, 2008, Lin et al. This is equal to almost 130% of the country's gross domestic product, GDP. When the probability of the favored category becomes very large, such as 70% (which is very rare), the above rule for assigning the probabilities for the two non-favored categories becomes different. Parts of the Northeast, Ohio Valley and far western United States could see heavy rains and snow toward the end of February. For more details on why these shifts were made, please see the local winter outlook tab below. Here at Patch, some of us were on the hype train by early July. Riddle,E. E.,M. B.Stoner,N. C.Johnson,M. L.LHeureux,D. C.Collins, andS. B.Feldstein,2013:The impact of the MJO on clusters of wintertime circulation anomalies over the North American region. For example, 9 of the 11 strong and moderate events show wetter-than-average conditions in the Pacific Northwestthough the intensity of the anomaly varieswhich is most winters, but not all. Climate,15, 905-914. The NAO loading pattern has been chosen as the first mode of a Rotated Empirical Orthogonal Function (EOF) analysis using monthly mean 500 millibar height anomaly data from 1950 to 2000 over 0-90N latitude. Given the northward shift of the storm track, relatively cold and wet conditions are favored over the northern Rockies and northern Plains, resulting in the enhancement of snowfall. And like for seasonal temperature and precipitation, knowing the state of ENSO is a pretty reasonable place to start. The effects are usually strongest in Northern Hemisphere winter. Because of the uncertainty involved, we give ranges and attempt to be as transparent as possible in conveying that these outlooks are indeed low-confidence. 2. Passing clouds. Hazardous Weather Outlook During La Nia winters, cooler-than-normal temperatures are typically found across western and central Canada, Japan, eastern China, southern Brazil, parts of western and southern Africa, and Madagascar. The Gulf of Mexico sea surface temperature is negatively correlated with the tropical Pacific sea surface temperature, meaning when the tropical Pacific is cooler than average (La Nia), the Gulf of Mexico is usually warmer than average. Now imagine another bike rider entering the stage on the left and pedaling slowly across the stage, passing the stationary bike (ENSO), and exiting the stage at the right. J. This doesnt include dustings or ice events; we are likely to have some of those, too. for the Upper Mississippi River Valley Please select one of the following: is slightly favoredinsoutheast Minnesota, northeast Iowa, andwestern Wisconsin. It is a persistent area of high pressure near Bermuda that pumps mild air into the region and pushes the storm track to our north and west. During the last 10 years (optimal climate normal), 5 winters of these winters have been among the warmest third, 4 have been near-normal, and only 1 has among the coldest third (2013-14 winter). National Oceanic and Atmospheric Administration That provides a significantly different picture, with the average of the latest events much warmer than the earlier ones. The Old Farmer's Almanac has released its winter forecasts, saying Western Washington can expect more rain than normal, with warmer temperatures and less snow. The longest La Nia lasted 33 months. What are the models telling you? That water is also cooler this year. Join our Farmhouse Today. Reviews of Geophysics,43, 1-36. The greater the difference, the stronger the La Nina is and more likely it is to influence weather patterns. On the other hand, La Nia is associated with a more wavy and northward shifted jet stream, which might be expected to enhance severe weather activity in the south and southeast. The trend is an important component of seasonal temperature forecasts. So the landscape has dried out. Example video title will go here for this video. With this much debt, and with a trend of unending . Science / Research Baldwin, 2002: Atmospheric Processes Governing the Northern Hemisphere Annular Mode/North Atlantic Oscillation. Mayfly Tracking, Latest Indeed, historic tornado outbreaks in1974,2008,and2011started during La Nia conditions. We predict well have several accumulating snow events in the immediate area over the course of the winter, with a couple more in our colder suburbs. What are other forecasters predicting for the Washington region? Top menu. And that tends to stack the deck for us to have actually a cooler than normal winter, especially after the first of the calendar year. See Tippett et al. Angela King is the local host of Morning Edition. Since long-range forecasts are rarely accurate or useful for finding . A pedestrian walks through the rain in November 2019 at Kerry Park in Seattle. Arctic Oscillation) may be at play and is worth further investigation. The MJO becomes organized during late March through May as the green shading covers one half of the planet, and brown shades the other half all along as these areas move west to east with time. The polar jet stream tends to ridge over a semi-permanent High Pressure over the North Pacific and dips towards the Pacific Northwest. This La Nia footprint is pretty intuitive. The highest shift in the probabilities is from southern California into southwest Texas, much of Florida, southeast Georgia, and southeast Alaska. These two boundaries define three categories: below-normal, near-normal, and above-normal. SEATTLE With the official start of winter little more than two months away, many in Puget Sound may be growing eager for colder weather to arrive so they can plan some exciting, wintry fun. We can break up the snow pattern further and look at the weakest and strongest La Nia events. La Nia literally means "the little girl." Strong MJO activity often dissects the planet into halves: one half within the enhanced convective phase and the other half in the suppressed convective phase. Storm Team4 Chief Meteorologist Doug Kammerer predicts when we'll get the coldest weather of the season. However, when there is enough cold air in place ahead of such storms, the precipitation can start as snow before usually changing over to an icy mix or plain rain. Rivers - Quick Look, Cold Other climate phenomena, such as the Arctic Oscillation or the Madden Julian Oscillation, as well as the random nature of weather, can also play a large part in how winter turns out. Washington . This winter we expect a weak to moderate La Nia to persist throughout the winter, with some weakening late. They both tend to develop during the spring (March-June), reach peak intensity during the late autumn or winter (November-February), and then weaken during the spring or early summer (March-June). increasing across southern parts of the state as the summer progresses. When it is sharply negative, conditions often, but not always, trend warm and dry. Climate Dyn.,40,17491766. The odds of a blockbuster noreaster coming up the coast and walloping us with snow is lower than average, but cant be entirely ruled out. Its fairly trivial to break the sample size in half and compare the temperature patterns for the older half to the more recent half. That means it's more appropriate to say that La Nia favors those conditions, rather than guaranteeing them. Precipitation will be above normal, with above-average snowfall in the far north and far south. Preparedness Weather Today Weather Hourly 14 Day Forecast Yesterday/Past Weather Climate (Averages) Currently: 53 F. However, these figures are based on about 20 different La Nia episodes, many of them from the 1950s, 1960s, and 1970s, and we have not removed the longer-term trends from the temperature and precipitation data used here. Until recently, the only solid evidence showing that more tornadoes occur during La Nia conditions was for winter (January-March), when the ENSO signal is strongest, but average tornado activity is relatively low (Cook & Schaefer, 2008). Part I: Month-to-month variability. Fire Weather For those curiouswhy this occurs, Nat Johnson wrote an article on it for the NOAA Climate Blog on May 27, 2021. Winter temperatures have steadily risen in Washington over the past 150 years, and snowfall amounts are in decline. Since 1949-50, 50% (9 out of 18) ofLa Nia winters have seen a second consecutive time in which the La Nia climate pattern emerged after a transition to ENSO-neutral conditions in the tropical Pacific. These second LaNia winters are highly variable with their temperatures, precipitation, and snowfall. Fast, informative and written just for locals. In much of the U.S., La Nia conditions are associated with increases in these environmental factors and in tornado and hail reports. However, tornado and severe weather activity is more variable (noisier and harder to predict) than ordinary weather (think temperature and precipitation), and any ENSO signal is harder to see. We have been doing winter outlooks since 2005-2006 and have evaluated ourselves after the fact for the past 16 winters. best winter forecast preceded the record-breaking Snowmageddon winter of 2009-2010, Our outlook for the winter of 2014-2015 was also quite successful, it was cold, with snow that totaled more than twice the average, has risen between 3 and 5 degrees across the region. The National Weather Services winter outlook does not include snowfall projections, but it calls for above average temperatures and near-average precipitation for the Washington region. Higgins, W., J. Schemm, W. Shi, and A. Leetmaa, 2000: Extreme precipitation events in the western United States related to tropical forcing. We do take these long-term trends into account in our winter outlooks. Warmer and drier winters are more likely during La Nia over more southern states, and this is exactly where seasonal snowfall tends to be reduced (4). StormReady The odds are relatively high on the three-tiered scale, with the CPC forecasting the probability of below normal temperatures between 40 and 50%. Sci.,28, 702-708. For temperature, theres a strong tendency for temperatures to be below average across some of the West and North, particularly in the Northern Plains, with a weaker signal for above-average temperatures in the Southeast, as shown in the image below. NOAA Climate.gov image using data fromESRLandNCEI. In 2011-2012, we called for near-normal temperatures, and it was 5 degrees warmer than average. Forecasts and model runs for the 2023 seasons will be posted here as they become available. Olympia, WA. Looking for a speaker? In contrast, only fiveElNios winters (25%) have been followed by another ElNio winter. In July, federal climatologists reported burgeoning odds for another La Nia winter, which typically makes for a rainier, snowier and cooler season in Washington. (2012) and Allen et al. But what's really going on in the climate system is that the tropical Pacific is cooling off and it's likely we'll have weak to moderate La Nina conditions. "La Nia strengthened in the last month, with below-average sea surface temperatures (SSTs) evident across most of the equatorial Pacific. During La Nia, the surface winds across the entire tropical Pacific are stronger than usual, and most of the tropical Pacific Ocean is cooler than average. For Washington, Oregon and Idaho, the Farmers Almanac winter forecast calls for "typical winter temperatures and precipitation.". The MJO can produce impacts similar to those of ENSO, but which appear only in weekly averages before changing, rather than persisting and therefore appearing in seasonal averages as is the case for ENSO. Nick Bond: Well they claim that they're 80% accurate. This year, the polar vortex may also be weaker, according to AccuWeather. NOAA typically releases its official winter predictions in October. La Crosse, WIN2788 County Road FALaCrosse, WI 54601608-784-7294Comments? Geophys. Already a member? Early February should also start rather cold and stormy, but the month looks to end on the warmer side. Thus, the mid-latitudes of North America, Europe, Siberia, and East Asia generally see fewer cold air outbreaks than usual during the positive phase of the AO. Blue shading shows Madden R. and P. Julian, 1972: Description of global-scale circulation cells in the tropics with a 40-50 day period. Are you ready for the upcoming winter season? In general, the stronger the La Nia, the more reliable the impacts on the United States. Home. Science,287, 2002-2004. NOAA Climate.gov image using data fromESRLandNCEI. The more vigorous storm track and slight tilt toward colder temperatures over the northern tier of the U.S. during La Nia modestly increase the chance of a relatively snowy winter. This tends to result in weather systems that push cold and moist airmass into our region. This U.S. Winter Outlook 2021-2022 map for temperature shows warmer-than-average conditions across the South and most of the eastern U.S., while below average temperatures are favored for southeast Alaska and the Pacific Northwest eastward to the Northern Plains. Notably, the forecast calls for: The Great Lakes and Northeast can expect potent winter storms heavy snow, rain or a wintry mix of both during the second week of January, the final week of February and the second week of March. The effects are usually strongest in Northern Hemisphere winter. Figure 1: Difference from average rainfall for all MJO events from 1979-2012 for November-March for the eight phases described in the text. The frequent presence of a southeast ridge. Res. In our region, La Nias, particularly moderate to strong events, are often associated with dry, mild winters with modest snowfall. From the AGU monograph on the North Atlantic Oscillation, 293, 85-89. Arent weather forecasts only reliable out to about eight to 10 days? There has been a fair amount of variability in the winter temperature and precipitation patterns during La Nia, but also that there are some clear tendencies for above or below normal temperature or precipitation in some regions. During the past 15 years (optimal climate normal). Washington Department of Fish & Wildlife. Thompson, D.W.J., and J.M. La Nia refers to abnormally cold water temperatures across the central and eastern equatorial waters (5N-5S, 120-170W)] of the Pacific Ocean. New e-regulations for coastal rivers for 2022-23 season: - Coastal rivers and tributaries fishing rules update (Nov 2022) More information. Overall, stronger La Nia events exert more influence on the winter climate pattern over western North America. varies on a week-to-week basis). Viewed from above either pole, these patterns show a characteristic ring-shape or "annular" pattern; thus, AO and AAO are also referred to as the Northern Annular Mode (NAM) and Southern Annular Mode (SAM), respectively. His unchanging location is associated with the persistent changes intropical rainfalland winds that we havepreviously describedas being linked to ENSO. February should offer some reprieve from storms. By contrast, the latest seasonal outlooks from the National Oceanic and Atmospheric Administration place very good odds on Washington seeing a wetter fall and winter. Want a tour? Snowstorms will occur at times this winter. This video and related map images can also be accessed at www.climate.gov/WinterOutlook2021. In addition to being the local presence during national programs, she also voices many of the sponsorships you hear on KUOW and on our podcasts. Southern Maryland usually gets less snow and could see 4-8 inches. On twooccasions, there have been threeconsecutive LaNia winters (1973-76 & 1998-2001). Climate Dyn., 38, 1459-1471. This will highlight those regions that often have temperature or precipitation anomalies of the same sign. Winter temperatures have steadily risen in Washington over the past 150 years, and snowfall amounts are in decline. The southwestern U.S. always was much drier than average, which is very common during La Nia for that part of the county. The negative phase reflects an opposite pattern of height and pressure anomalies over these regions. Climate,13, 793-820. This year looks like a moderate La Nia, which can mean winter storms. Emergency Management La Nia is when those ocean waters are colder than normal. The status of the PDO between 1950 and this year, shown at bottom, indicates a predominantly positive phase from about 1978 to 1998 and a negative phase since 1999. La Nia is likely to continue through the Northern Hemisphere winter 2021-22 (~90% chance) and into spring 2022 (~50% chance during March-May). Release Date: Apr. The highest shift in probabilities is from Washington east into western Montana and from southeast Missouri northeast into Michigan, and in western Alaska. I actually looked at their forecasts from some years ago -- 13 winters, their monthly precipitation totals, and average temperatures relative to normal for Western Washington and Western Oregon. In the Upper Mississippi River Valley, these winters can be highly variable with both temperatures and precipitation. While the upcoming La Nia is likely to be weaker than the last, other elements factor into the winter forecast especially during the second half of the season. Yeah, so the Farmer's Almanac has is wetter than normal and warmer than normal. Community Involvement No way, experts say. Winter (December-February) temperature during strong, moderate, and weak La Nias since 1950 (Winter 2017-18 not included), Midwest La Nia Winter (DJF) Average Temperature Departures(23 Winters since 1949-50), Author:Tom Di Liberto(October 12, 2017). After our second-warmest October on record, the first week of November delivered a chill, offering a taste of the inevitable. Thus, the season didn't get as much snow as originally forecasted, but at 50.1 inches of snow was still slightly snowier than the normal season for Spokane. This results in more upwelling of cold water off the Peruvian coast which results in even colder waters in the central and eastern equatorial waters. The highest shift in the probabilities is from northwest Oregon and Washington east into the . Wednesday, May 17, 2023 - 9 a.m. - 12:00 p.m.: Register. Zhang, C., 2005: Madden-Julian Oscillation. The location of the convective phases is often grouped into geographically based stages that climate scientists number 1-8 as shown in Figure 1. Temp/Pcpn Summary The MJO consists of two parts, orphases: one is the enhanced rainfall (orconvective) phase and the other is the suppressed rainfall phase.
