Jamstec used to have a lot of information on their website but much of it seems to have left after a reported breach a couple of years back. Karen S. Haller. One of the main points of this post is that it's difficult to rule out the role of chaotic atmospheric variability that is unrelated to the underlying sea surface temperatures when it comes to unusual Southwest U.S. precipitation. Difficult to impossible travel across wide swaths of U.S. due to coast-to-coast storm. You can see that jet stream redirection in the image below. Let us know. But take note of the trough of equal temperatures probability extending down low into the south-central states. This winter it seems the temps were fairly uniform across the equator. Below normal temperatures are favored from the Pacific Northwest eastward to the western Great Lakes and the Alaska Panhandle. Higher temperatures are forecast for the West; WeatherBell projects temperatures 1 to 3 degrees above normal in the Southwest. The ENSO influence is spread globally through this feedback system, creating different Winter temperature and snowfall patterns. Thanks for raising some good points! Seasonal Forecast for February - April 2023. This looks close to a usual historical snowfall pattern in a La Nina winter. The Farmers' Almanac has released its extended winter forecast for 2022 and 2023 in the United States. Hourly. One way we could try to address this question is to group both the wettest and driest La Nias over the Southwest in December-January and then see if there are notable differences in the sea surface temperature patterns that occurred during wetter La Nias versus drier La Nias. But what's the long-range outlook for the next three months? A spokesperson for the Met Office told i: With this low pressure out to the west, with the way the jet stream is positioned at the moment, its helping to spin these weather systems in towards the UK. Thanks, Tom. As its normally colder higher up in the atmosphere, when the air rises up a hill, it becomes colder, and condenses to form cloud and precipitation. Looking at the overall average forecast and comparing it to the previous forecast, we can see that the latest run has less snowfall over most of Europe, except towards the east and south. We see an increased snow potential over the upper Midwest, with some other areas across the Midwest having normal snowfall amounts forecast this month (0/white areas). Comments must be on-topic; free of profanity, name-calling, or ad-hominem attacks; and cannot repeat misinformation about climate that has been widely debunked by authoritative sources. My conclusion: the chaotic weather variations are about 14 times more important than the variations in La Nia amplitude or flavor for Southwest U.S. precipitation, which is consistent with the figure above. Have a comment on this page? La Nina does change the weather globally, but apart from the direct influence over North America, places like Europe have many other factors in circulation before any La Nina influence can spread this far. If there is one basic theme I've learned from all the postings on this blog is that our climate is very complex with many different parts and ENSO is just one big part of it so there is always going to make any winter outcome far from certain. Submitted by Finn Stiles on Sat, 02/25/2023 - 05:01. We always focus on trends and probabilities, but still, variation is key. One exception is southwestern Canada and higher elevations in the western/northwestern United States. Are you Weather-Ready for spring hazards? AccuWeather 's approach to concocting the winter forecast . NOAAs seasonal outlooks provide the likelihood that temperatures and total precipitation amounts will be above-, near- or below-average, and how drought conditions are anticipated to change in the months ahead. There are also some hints of a cold event reaching down to the south-central United States. So, that gets to the main point of the post. Looking at the temperature analysis for the same winters, we can see a cold anomaly under the jet stream in western Canada and the northern United States. Patchy cloud with some clearer skies. (NOAA) ), and I have seen that there are a few studies that point to processes around Antarctica that could be contributing. Submitted by Clara Deser on Sat, 02/25/2023 - 11:39. Reporting on Earths changing climate and the people trying to find solutions to one of the biggest challenges of our era. Overall, the UKMO is much more dynamic than the ECMWF and leaves more possibilities open regarding pattern development. WeatherBell is forecasting slightly above-normal snowfall, 125 percent of the seasonal average, in the Midwest, through the Ohio Valley and into the interior Northeast. To better understand the ENSO changes, we produced a video showing the La Nina anomalies from Summer into Fall. Submitted by Craig T on Thu, 03/02/2023 - 18:31, In reply to forecast busts by Nathaniel.Johnson, Submitted by Nathaniel.Johnson on Fri, 03/03/2023 - 10:31, Minor correction. Last month was. 16 day. The effects of air rising up hills and mountains must also be considered. For this analysis, I am using simulations of monthly climate from the Geophysical Fluid Dynamics Laboratory (GFDL) climate model called SPEAR, the same model that contributes seasonal forecasts to the North American Multi-Model Ensemble (NMME), but here the experiment is designed to analyze the climate effects of the observed sea surface temperature evolution from 1951-2020 (4). Everything I read details how little we understand and have modeled such an occurrence- a gigantic and long-lasting (it will take years for the extra water vapor to dissipate) change to something that we think of (and model) as utterly constant and stable. Submitted by Nathaniel.Johnson on Wed, 03/01/2023 - 12:10, In reply to Arctic amplification (?) Snowfall rates may reach 1"/hr at times, and travel will likely . (Image credit: Getty images), Video highlights from NOAA's 2022-2023 Winter Outlook that provide seasonal predictions for temperature, precipitation and drought. Winter Forecast 2022/2023 - November Update: Cold ENSO phase peaks, with its growing weather influence as we head for the start of the Winter . The relief from an unrelenting drought was welcome, but too much of a good thing also meant flooding, mudslides, and dangerous debris flows. Although the official winter forecast from the National Oceanic and Atmospheric Administration will not come out for another few weeks, the agencys Climate Prediction Center does issue official outlooks for temperature and precipitation up to 13 months in advance. Difference in DecemberJanuary precipitation anomalies (percent of the 1991-2020 climatology) between the wettest 20% and driest 20% of Southwestern U.S. La Nia outcomes simulated by the GFDL SPEAR climate model. Pacific Southwest Another mild winter is expected this year, Goble said. Warmer than normal weather and mild winter conditions typically develop over the southwestern United States, eastern United States, and eastern Canada. Between 2013 and 2022, we delivered an organic revenue CAGR of 11. . While their predictions won't delight those who hate changeexpect back-and-forth weather patterns across the countryfor the most part, winter won't be harsh. (NOAA Climate.gov, using NWS CPC data) Download Image Temperature The greatest chance for warmer-than-average conditions are in western Alaska, and the Central Great Basin and Southwest extending through the Southern Plains. Over the coming days, cold Arctic air will descend on the UK like a hoard of shoppers on a clothing store in the Boxing Day sales, plunging us into a period of frigid conditions that may well last right through the middle of December and into the run up to Christmas. The latest breakthroughs, research and news from the Met Office. Meanwhile, the southern U.S. is expected to have a. The main takeaway for much of the country: Expect snow, rain and mush, and a lot of it,. But now, we will look at actual Winter snowfall predictions from the latest forecast models. The February snowfall forecast shows snowfall potential remaining over the northern parts of the United States. So far, the storm season in the UK has been decidedly quiet, with not a single named storm featuring so far. So, I did not see any obviously linear effect of La Nina amplitude in the observational analysis. Above all thank you for the richness of the information but i take note that some (data simulation methods) may tend to under-estimate (under fit) and others may overestimate (over-fit) an ulterior assumption , choosing the best ( mathematical) simulation methods may sometimes tell a good tale even with the presence of short data window . Among the winter outlooks issued by meteorologists so far, most agree that the southern United States will be drier and warmer than normal, with the best chance of colder and stormier-than-normal conditions in the northern tier, Midwest and Ohio Valley. If youre struggling to identify any meaningful sea surface temperature differences in the map above, then you and I are in the same boat (5). Durango Herald 3:40 AM MST on Mar 4, 2023. Places where precipitation was less than 100 percent of the 1991-2020 average are brown; places where precipitation was 300 percent or more than average are blue-green. This will be followed by the Quadrantid Meteor Shower . Its conceivable that such differences could influence precipitation in the Southwest U.S., but these differences are much smaller than the amplitude of the largest average La Nia tropical Pacific sea surface temperature anomalies, which approach 2 Therefore, it is difficult to see how such small sea surface temperature differences could have an influence that is comparable with the average La Nia influence. What is this gigantic hole that has appeared in the fields of Turkey? From my experience, the superposition of the ENSO and MJO teleconnections can be treated as linearly additive, so the MJO influence (like what's shown here) can constructively or destructively interfere with the expected ENSO influence. Remaining very mild. A Tale Of Two Winters Across The US, According To Old Farmer's Almanac The Old. How important is the difference in La Nia intensity between the two samples. Submitted by Matt on Thu, 02/23/2023 - 11:44. Between 9 and 23 November there could be an increasing chance of settled weather from mid-month, bringing a potential for colder, drier weather especially for the north and west, it said. However, for the UK, being an island surrounded by the milder water, the air can often warm up slightly before it reaches our shores, and we often see rain rather than snow, or, even trickier to forecast; a mix of rain, sleet and snow.. However, climate scientists continue to investigate this topic, and hopefully we will have greater scientific consensus in the years ahead. If one expects a deterministic forecast (it WILL be wet or it WILL be dry), then both the forecaster and user will be disappointed quite often. This atmospheric river onslaught surprised many who were expecting a dry season, especially in the Southwest, not only because of the prolonged drought, but also because La Nia tends to bring drier-than-average winter conditions to the region. The figure below shows that most (13 of 21) of the La Nias from 1951-2020 had below-average December-January precipitation in this region (1), although wet early winters during La Nia . There is an increased chance of above-normal temperatures for the winter season and an increased chance of below-normal precipitation. Colorado Avalanche Information Center forecasters need intricate knowledge of snowy layers that sit below the surface as they warn public of hazards and risks. Their study states these types of events result in a different atmospheric response. The seasonal outlook looks at temperature and precipitation trends between December 2021 through February 2022. ET. The figure below shows that most (13 of 21) of the La Nias from 1951-2020 had below-average December-January precipitation in this region (1), although wet early winters during La Nia clearly are not that unusual. The U.S. Winter Outlook 2022-2023 map for temperature shows the greatest chances for warmer-than-average conditions in western Alaska, and the Central Great Basin and Southwest extending through the Southern Plains. However, we still need more analysis to see if the particular sea surface temperature pattern this year played some role, including the unusual frequency of atmospheric rivers. That's still down 45% from a year earlier, however. Wetter-than-average conditions are most likely in the Pacific Northwest, the northern Rockies, Great Lakes, and Ohio Valley. Below-normal temperatures are favored from the Pacific Northwest eastward to the western Great Lakes and the Alaska Panhandle. - 29 US states are under winter weather alerts as people brace for a winter storm expected to bring heavy snow . Did La Nia drench the Southwest United States in early winter 2022/23? Above-normal precipitation is possible in northwestern Montana, northern Idaho and northeastern Washington state. Europe features mostly warmer than normal conditions over northern parts, with a storm track over the southwest . Just checking the maps at this site, we can see some regions, like you mention, that have been drier than normal over the past 60 days. That means that most teleconnection patterns that influence U.S. climate are what we consider "internal to the atmosphere" and tend to grow and decay on time scales of a couple of weeks. They have literature on Modoki La Ninas. air travelling from north to the south) bring the air straight from the Arctic and over a cold sea to reach the UK. Finally, do you have any comment on the unusual persistent La Nina-like SOI and multivariate ENSO index (MEI) for the 2020-23 La Nina despite occasional neutral Nino34 SSTA lapses? August 29, 2022 NOAA's 2022-2023 Winter Forecast The US National Oceanic and Atmospheric Administration ( NOAA) makes long-range forecasts each month. The notably small sea surface temperature differences between the wet and dry groups indicate that the sea surface temperature pattern plays a very minor role in the Southwest precipitation differences during La Nia, according to the climate model. Winter Forecast for Southwest Michigan for 2022/2023 Impactful Winter Weather On the Way A storm system will move into Lower Michigan for Friday, bringing primarily snow but some light freezing rain could mix in across the far south. We have also produced an image that shows the snowfall forecast change compared to the forecast from the previous month. The more forecast data you can look at, the better idea you can get about the expected weather patterns. These represent the range of variation when the only thing were taking into account is its a La Nia winter. Then, for each of those 21 years, I looked at the range of outcomes across the 30 simulations, thus including the chaotic, unpredictable weather variability. A person clears their car of snow to go to work, in Provo, Utah, on Feb. 22, 2023. Support your business with world-leading science and technology. Share. Because the observed record is too short to tease out the relationships we seek with sufficient precision, we rely on climate models to sharpen the signal relative to the noise of random weather variability. This seasonal U.S. Drought Outlook map for November 2022 through January 2023 predicts persistent widespread drought across much of the West, the Great Basin, and the central-to-southern Great Plains. Areas depicted in white are regions where climate signals are weak and I'm pleased you're joining us today to discuss the Southwest Gas Holdings fourth quarter and year-end results. La Nina usually forms during strong trade winds, which can tell us much about the state of global circulation. Check out our new Learn Weather page linked below, containing information on all things related to weather in all the seasons! . Historically, a strong blocking high-pressure system in the North Pacific is the most typical effect of a cold ENSO phase. January snowfall forecast shows a similar pattern, with more snowfall over much of southern Canada and the northern half of the United States. . Warmer-than-average temperatures are also favored in the Southeastern U.S. and along the Atlantic coast. We either require the cold air to meet a rain-bearing weather front and turn it into snow, or for the cold air to pick up enough moisture from its short journey across the North Sea, to form showers..
