Thanks, Tom. On average across the UK, there are only 15.6 days a year when snow is on the ground, though this rises to 26.2 days for Scotland alone. That's why Nat used model simulations to look at the relationships here, finding that there's no preferred pattern to the sea surface temperature for wet SW winters. January 2023 La Nia update, and the ENSO Blog investigates, part 2, SST - ENSO Region, Monthly Difference from Average, El Nio-Southern Oscillation - Indicators and technical discussions, Detecting El Nio in Sea Surface Temperature Data. Over North America, most of the country has below-average snow accumulation, except for the northwestern United States, upper Midwest, and southwestern Canada. In winter, the land gets cold more quickly than the sea, so where there is a lot of land and very little sea, such as the huge interior of continental Europe, Canada or the United States, it gets cold enough for snow to fall frequently, it says. Distribution of DecemberJanuary precipitation anomalies (percent of the 1991-2020 climatology) in the Southwest U.S. (region defined in the figure above) for all 21 La Nias from 1951-2020. So, I did not see any obviously linear effect of La Nina amplitude in the observational analysis. Apparently 24 years ago the NWS office for Flagstaff moved from the airport to a community(Bellemont) just west of Flagstaff. Meanwhile, the southern U.S. is expected to have a. Turning wet and windy from the west on Monday. 2022-2023 California and Southwest Weather Thread Maximum temperature 7C. La Nina is a climate pattern that originates in the Pacific Ocean but impacts the global weather forecast. 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. Southwest U.S. Newfoundland, Labrador; Nova Scotia, Prince Edward, New Brunswick, Quebec; Ontario; Alberta, Manitoba, Saskatchewan; British Columbia; 2023 Summer Extended Forecast; 2022-2023 Extended Winter Forecast; 2022-2023 Canadian Extended Winter Forecast; 20 Signs Of A Hard Winter Ahead; Weather Lore; Weather History; Our Forecast Accuracy Submitted by Nathaniel.Johnson on Thu, 03/02/2023 - 09:50, In reply to Other teleconnections by Stan Rose. I realize that this winter has been more eventful in other parts of the country, notably in the western U.S., where torrential rains and heavy mountain snows occurred in December and January. 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).

If there aren't any climate researchers looking into this now, I'm sure there will be some soon! As always, we start with the ECMWF, the most often used and highly regarded seasonal forecasting system. When we divide up the observed record even further, e.g. Much of this snowfall does not settle, and the figures for snow on the ground (snow lying) are much lower.

The Majority of these Atmospheric Rivers have missed this area and only the last month has some of the area received measurable Moisture. I don't have an explanation except to speculate that the multidecadal enhancement of the zonal sea surface temperature gradient (like what was described in this post) is helping to keep the tropical atmosphere more La Nina-like even when the typical ENSO sea surface temperature indexes are deviating from typical La Nina values. The precipitation anomalies are divided into 10 evenly spaced bins, and the number of La Nia events is totaled for each bin. into central Pacific vs. east Pacific La Nia events, we end up with a pretty small sample size. We have a proven track record of top and bottom line growth. Winter- It's Coming! Colorado Avalanche Information Center forecasters need intricate knowledge of snowy layers that sit below the surface as they warn public of hazards and risks. Precipitation-wise, La Nina winters are usually drier over the southern United States. which became the state's newest city in January 2022, .

Seasonal outlooks help communities prepare for what is likely to come in the months ahead and minimize weather's impacts on lives and livelihoods. I follow that convention here, though Im really calculating the inverse, meaning the noise-to-signal ratio. Drier conditions also develop in the southeastern United States as La Nina produces a weaker subtropical jet stream and less moisture over the southern United States. Besides the northwestern United States and the Midwest, we can see more snowfall potential over the northeastern United States and eastern Canada. This looks close to a usual historical snowfall pattern in a La Nina winter. That can be interpreted as a potential route of winter cold air outbreaks down from the Midwest to the south, creating occasional snow events. Submitted by Nathaniel.Johnson on Sun, 02/26/2023 - 20:08, In reply to Thanks Nat for this cogent by Clara Deser. Question: Will you also be writing a paper about this? After this, the December Full Moon will fall on December 19 and the Winter Solstice - marking the shortest day of the year - will occur on December 21. More snowfall is also seen over parts of the upper Midwest. For the first three months when winterlike conditions begin in earnest November, December and January abnormal cold is not expected anywhere in the country. The brown bars indicate events with below-average precipitation, and the green bars indicate events with above-average precipitation. View the weather with our interactive map. Here is the forecast for the coming days. The start of this period is expected to be characterised by winds from the north bringing cold conditions to most areas with widespread frost and ice. Above-normal precipitation is forecast in part of the Ohio Valley, an area that could pick up above-normal snowfall if temperatures remain low enough. Long-range weather forecast for winter 2022 and temperature predictions The Met Office has warned that snow may appear across the north and west of the UK as early as 9 November A snowy. 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.. Long-range weather forecasting is not easy, and there are a lot of factors that impact seasonal climate. December is favored to be the chilliest month on the Eastern Seaboard, with lower-than-normal temperatures expected from the Great Lakes down into parts of the Mid-Atlantic and Northeast. 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. The next update will be available November 17. NOAA Official precipitation outlook points: Also, we will keep you updated on other developing weather trends, so bookmark our page. 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. The lowest temperatures are expected in the Ohio Valley into the Upper Midwest, which are forecast to be 1 to 3 degrees below normal. is favored for the Southwest, eastern areas of the Great Basin, as well as parts of the central and southern Rockies. La Nia. Below is an image that compares the latest forecast to the previous one. Reports from . This will most likely result in wintry showers, these turning more organised at times in the north and east. Not sure how much that was a factor. My question, regarding the un-forecast DEC/JAN 2022-23 is whether the heavy precipitation was contributed to by the unusual presence of warming near and east of the Dateline referred to by NOAA as "warm blob" NEP22A and NEP23A? Winter will feel unreasonably cold from the Great Lakes region to the Mid-Atlantic, especially in January, The Farmers' Almanac says in its first forecast for 2022-23.

The logical conclusion is that, according to the climate model, unusually heavy Southwest U.S. precipitation during December-January of La Nia has very little to do with the sea surface temperatures and instead is more closely tied to short-term and seasonally unpredictable weather conditions, as captured by the variations among the 30 simulations for a given La Nia. (Image credit: Getty images), Video highlights from NOAA's 2022-2023 Winter Outlook that provide seasonal predictions for temperature, precipitation and drought. air travelling from north to the south) bring the air straight from the Arctic and over a cold sea to reach the UK. Submitted by John N-G on Thu, 02/23/2023 - 15:04. 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. Regions further east, on the other hand, will probably experience precipitation levels more typical for the time of year. And did tropical sea surface temperatures contribute? The relief from an unrelenting drought was welcome, but too much of a good thing also meant flooding, mudslides, and dangerous debris flows. We can also track snowfall potential on normal temperature and precipitation Winter forecasts. We can see that the latest ECMWF forecast shows less snowfall over most of the continent compared to last months forecast for the entire Winter season. 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. But now, we will look at actual Winter snowfall predictions from the latest forecast models. Year-Long Guide to Great Living The 2023 Farmers' Almanac offers 16 months of weather prediction starting with September 2022 going through December 2023. The bottom line is that La Nia may tilt the odds toward dry early winter conditions in the Southwest, but La Nia clearly does not eliminate the chance of wet conditions either. Im basically doing a signal versus noise calculation. I agree, a very interesting post! Finally, the persistently positive SOI and MEI is an interesting observation. La Nia could enter rare third straight year. The February snow depth forecast shows the snowfall potential reducing further over most of Europe. Winters coming: Heres what to know about long-range weather outlooks. We will do a monthly breakdown, as there are a lot of details in the monthly forecast that the whole seasonal average does not show. AccuWeathers official 2022-2023 U.S. winter forecast is rather bleak for snow lovers. With snow accumulation up to 88 inches, and entire summers with temperatures below freezing, the northern hemisphere was rattled with Satan's snow. ENSO phases significantly influence tropical rainfall, pressure patterns, and the complex exchange between the ocean and the atmosphere. Overall, the UKMO is much more dynamic than the ECMWF and leaves more possibilities open regarding pattern development. 2021 Associated Newspapers Limited. The blue bars indicate the chance of La Nia for each three-month period into winter 2022-23, according to this forecast from early May 2022. . This cold ocean phase is entering its final stage and will break down as we get into Spring. We are going to show you their forecast for the upcoming winter, but first, a warning. Therefore, the variations among these 21 ensemble-averaged values, quantified as a standard deviation of 0.194 mm/day, largely reflect the effects of the different sea surface temperature patterns among the 21 La Nias. Records back to 1893 are considered the most reliable and qualify for the "modern" record. 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. 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. A somewhat subjective rating of the day's weather, on a scale of 0 to 10. Could the jet stream also have influenced precipitation amounts ? AccuWeather long-range forecasters are predicting that 40 to 50 inches will accumulate in the city, around the average snowfall amount of 49.2 inches. This is an active area of research and model development, and I know that there are many in my lab who are working on improving the representation of stratospheric processes in our models.
