One thing leaning against this winter being warmer than normal is that 4 out of the 5moderate La Nia winterswere among the coldest third (the winters of 1955-56, 1970-71, 1984-85, and 2010-11) and the other one had near-normal temperatures (winter of 2020-21). So the landscape has dried out. For the East and Midwest, for example, a late winter storm will blow in at mid-month followed by a noreaster along the East Coast toward months end.". The MJO was first discovered in the early 1970s by Dr. Roland Madden and Dr. Paul Julian when they were studying tropical wind and pressure patterns. 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. It turns out their ideas are very similar to ours, and there is a strong consensus for near to slightly above-average temperatures and near to below-average snowfall. La Nia refers to abnormally cold water temperatures across the central and eastern equatorial waters (5N-5S, 120-170W)] of the Pacific Ocean. But overall, temperatures should work out close to average. The MJO consists of two parts, orphases: one is the enhanced rainfall (orconvective) phase and the other is the suppressed rainfall phase. The highest shift in the probabilities is from southern California into southwest Texas, much of Florida, southeast Georgia, and southeast Alaska. 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. 2020-2021 winter outlook | 2020-2021 winter outlook recap, 2019-2020 winter outlook | 2019-2020 winter outlook recap, 2018-2019 winter outlook | 2018-2019 winter outlook recap, 2017-2018 winter outlook | 2017-2018 winter outlook recap, 2016-2017 winter outlook | 2016-2017 winter outlook recap, 2015-2016 winter outlook | 2015-2016 winter outlook recap, 2014-2015 winter outlook | 2014-2015 winter outlook recap, 2013-2014 winter outlook | 2013-2014 winter outlook recap, 2012-2013 winter outlook | 2012-2013 winter outlook recap, 2011-2012 winter outlook | 2011-2012 winter outlook recap, 2010-2011 winter outlook | 2010-2011 winter outlook live chat | 2010-2011 winter outlook recap, 2009-2010 winter outlook | 2009-2010 winter outlook recap, 2008-2009 winter outlook | 2008-2009 outlook live chat | 2008-2009 winter outlook recap, 2007-2008 winter outlook | 2007-2008 winter outlook recap, Local guides, travel tips and the latest industry news, Brace for a wild winter in Washington, but its no thrill for snow lovers. But right now, I would say that the evidence is not necessarily far warmer than normal winter overall. Shrimp po boys and live music: Big Freedias New Orleans favorites. The entire system shifts eastward over time, eventually circling the globe and returning to its point of origin. These remain low-confidence forecasts. Washington . La Nina winter weather in Seattle | king5.com 1: The tornado environment index (TEI) and hail environment index (HEI) are functions of monthly averages of convective precipitation, convective available potential energy, and storm-relative helicity. 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. After our second-warmest October on record, the first week of November delivered a chill, offering a taste of the inevitable. 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). NOAA calls for stormy winter across the northern U.S. but mild, dry weather elsewhere. AO phases are analogous to the Southern Hemisphere's Antarctic Oscillation (AAO), a similar pattern of air pressure and jet stream anomalies in the Southern Hemisphere. The green shading denotes conditions favorable for large-scale enhanced rainfall, and the brown shading shows conditions unfavorable for rainfall. Sun & Moon. to occur from about October 2021 to January 2022. . 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. Snow lovers are unlikely to be pleased as were projecting below-average amounts for the fifth time in the past six winters. AccuWeather 2021-2022 winter forecast: Which parts of the U.S. will be 2022 has lagged behind 2020 and 2021 while faring better than 2018 and 2019 across most of the home price spectrum . National Weather Service The highest shift in the probabilities is from northwest Oregon and Washington east into the . For more details on why these shifts were made, please see the local winter outlook tab below. Climate Dyn., 38, 1459-1471. 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. Nature,455, 523-527 doi:10.1038/nature07286 Letter. "La Nia strengthened in the last month, with below-average sea surface temperatures (SSTs) evident across most of the equatorial Pacific. The U.S. government has a debt of $31.5 trillion. AccuWeather's long-term forecasts predict Seattle's earliest brush with near-freezing overnight temperatures will arrive just a couple of days after Thanksgiving, with wet weather on tap for the entire holiday week. However, as is evident in these maps, there is a great deal of variability even among strong La Nia events. US Dept of Commerce La Nia episodes typically last 9-12 months. How Much Snow to Expect: Doug's 2021-22 Winter Forecast In July, federal climatologists reported burgeoning odds for another La Nia winter, which typically makes for a rainier, snowier and cooler season in Washington. This tends to result in weather systems that push cold and moist airmass into our region. They often noticed regular oscillations in winds (as defined from departures from average) between Singapore and Canton Island in the west-central equatorial Pacific (Madden and Julian, 1971; 1972; Zhang, 2005). the Inland Northwest's long-range winter forecast in . Gulf of Mexico sea surface temperature is close to the part of the U.S. most strongly impacted by severe weather: warm Gulf of Mexico surface water in spring enhances low-level moisture transport and southerly flow and is associated with enhanced US tornado and hail activity (Molina et al., 2016). 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). Precipitation Reports Storm Team4 Chief Meteorologist Doug Kammerer predicts when we'll get the coldest weather of the season. Long-Range Weather Forecast for 2022 | The Old Farmer's Almanac For Washington, Oregon and Idaho, the Farmers Almanac winter forecast calls for "typical winter temperatures and precipitation.". La Nias typically occur every 3 to 7 years. Climate, 13, 1000-1016. Future posts will focus on the details of how we monitor and assess the strength of the MJO, provide details on impacts and the reasons for those impacts, and describe the current state of MJO predictability. The publication expects January to start out mild for most of the country, becoming colder toward the middle or latter part of the month. We have been doing winter outlooks since 2005-2006 and have evaluated ourselves after the fact for the past 16 winters. Wea. We see winter getting off to a fast start and lean toward a colder-than-normal December. Study says specific weather forecasts cant be made more than 10 days in advance. For those curiouswhy this occurs, Nat Johnson wrote an article on it for the NOAA Climate Blog on May 27, 2021. 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. Our snowfall projection covers November through April. Expect 7-13 inches in the D.C. metro area and along the Interstate 95 corridor. The federal budget deficit in 2022 exceeded $1 trillion and is widely expected to remain at that level for the foreseeable future. Instead of only looking at individual weather events, its important to consider the environmental cues for the outbreak of severe weather. Maloney E. and D. Hartmann, 2000: Modulation of hurricane activity in the Gulf of Mexico by the Madden-Julian Oscillation. The positive phase of the NAO reflects below-normal heights and pressure across the high latitudes of the North Atlantic and above-normal heights and pressure over the central North Atlantic, the eastern United States and western Europe. Widespread, ongoing drought is currently in place across the western half of the continental U.S. and in parts of Minnesota, northern Iowa, Wisconsin, and northern Illinois. DST Changes. Reduced snowfall is observed over parts of the central-southern Plains, Southwest, and mid-Atlantic. The typical U.S. impacts are warmer- and drier-than-average conditions across the southern tier of the United States, colder-than-average conditions across the north-central Plains, and wetter-than-average conditions in the Ohio Valley and Pacific Northwest/Northern California. Home. The Climate Prediction Center's current long-range outlook shows favorable chances for below-average temperatures and above-average precipitation between December and February. The highest shift in the probabilities is from northwest Oregon and Washington east into the western Dakotas and in southeast Alaska. Could Disney move out of Florida? StormReady Nathaniel C. Johnson, Dan C. Collins, Steven B. Feldstein, Michelle L. LHeureux, and Emily E. Riddle, 2014: Skillful Wintertime North American Temperature Forecasts out to 4 Weeks Based on the State of ENSO and the MJO*. As we progress toward the fall and winter months (August-September-October, ASO 2023 through January-February-March, JFM 2024), El Nio is expected to become more of a factor and the pattern begins to increasingly reflect El Nio conditions during the cold months. But just because Spokane's La Nia forecast wasn't perfectly on par with the textbooks, it doesn't mean the rest of the country's was off. Sign in. The Nio-3.4 index has a 66% chance of reaching a value less than -1.0C duringNovember 2021 - January 2022, but only a 14% chance of being below -1.5C. The negative phase reflects an opposite pattern of height and pressure anomalies over these regions. Zhou S., M. LHeureux, S. Weaver, and A. Kumar, 2012: A composite study of MJO influence on the surface air temperature and precipitation over the Continental United States. Community Involvement Jones, C. and L. Carvalho, 2002: Active and Break phases in the South American Monsoon System. For the MJO to be considered active, this dipole of enhanced/suppressed convective phases must be present and shifting eastward with time. Nisqually Boardroom 1D2. Res. 2. Dispatch / Law Enforcement Here's what a 'double dip' La Nina winter means for Washington Indeed, historic tornado outbreaks in1974,2008,and2011started during La Nia conditions. 11, 2023 | Forecast Completed: Apr. Climate averages or normals warmed around 1 to 2 degrees in every winter month between the 1981-2010 and 1991-2020 periods alone. La Crosse, WIN2788 County Road FALaCrosse, WI 54601608-784-7294Comments? 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. 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. Generalized Walker Circulation (December-February) anomaly during La Nia events, overlaid on a map of average sea surface temperature anomalies. Close. Thus, at its peak, a moderate-strength La Nia is favored" this winter. More is expected to the north and west, with 12-18 inches in areas like Leesburg, Dulles International Airport and Gaithersburg. References For La Crosse, the temperature and precipitation data extend back to the 1872-73 winter and snowfall back to 1895-96. And I was not convinced that they had much skill in their forecasts. Due to this, the CPC winter temperature and precipitation outlooks are consistent with typical La Nia impacts across much of the United States. Staff Below are some, though not all, of the factors that we considered in determining conditions for this upcoming winter. For more information, please visit the NCEIandClimate Prediction Center NAO pages. Or worse. Locally,wetter-than-normal is slightly favoredinsoutheast Minnesota, northeast Iowa, andwestern Wisconsin. However, as is evident in these maps, there is a great deal of variability even among strong La Nia events. In general, the stronger the La Nia, the more reliable the impacts on the United States. Climate.gov drawing by Fiona Martin. Midwest La Nia Seasonal Snow Departures (23 Winters since 1949-50), Author:Michael K. Tippett and Chiara Lepore In 2011-2012, we called for near-normal temperatures, and it was 5 degrees warmer than average. High pressure over Greenland or high-latitude blocking helps push the storm track farther south and east, often creating storm tracks that are cold and snowy for our region. I am also looking at the north Pacific, just south of Alaska. ENSOshifts the atmospheric circulation(notably, thejet stream) in ways that affect wintertemperature and precipitation over the U.S. Climate.gov figure based on analysis at CPC using Rutgers gridded snow data. Temperatures tend to be colder than average across the northern Plains and warmer than average across the southern tier of the United States. This was based upon recent trends over the past decade. Cassou, C., 2008: Intraseasonal interaction between the Madden Julian Oscillation and the North Atlantic Oscillation. This was the major factor in our historically snowy winter of 2009-10. Are you ready for the upcoming winter season? Observations TEI and HEI are calibrated to match the recent climatology of tornado numbers and hail events.

Snowfall departure from average for weaker La Nia winters (1950-2009). What is your long-term track record with these winter outlooks? Storm Team4 Chief Meteorologist Doug Kammerer predicts when we'll get the coldest weather of the season. Higgins, W., J. Schemm, W. Shi, and A. Leetmaa, 2000: Extreme precipitation events in the western United States related to tropical forcing. 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. The green shading denotes above-average rainfall, and the brown shading shows below-average rainfall. Weather Today Weather Hourly 14 Day Forecast Yesterday/Past Weather Climate (Averages) Currently: 53 F. 2009, Zhou et al., 2012, Riddle et al., 2013, Johnson et al., 2014). This winter is expected to be a "weak" La Nina, with temperature departures only expected after 0.6 to 0.7 Celsius cooler than normal. Lets dig a little deeper and look at some of the characteristics within these two convective phases (Figure 3). Here's every snow forecast made for D.C. for the upcoming winter By Jason Samenow Updated December 3, 2021 at 4:24 p.m. EST | Published December 3, 2021 at 3:37 p.m. EST The following video highlights from NOAA's 2021-2022 Winter Outlook that provide seasonal predictions for temperature, precipitation, and drought. Science / Research Time/General. Also, there is a tendency toward below-average snowfall over the mid-Atlantic, New England, and northern and central Plains, which is not seen during weak La Nia.
