Hopefully Nat will have a chance to turn this into a paper, but it will have to wait for a lull in his schedule. Seasonal outlooks help communities prepare for what is likely to come in the months ahead and minimize weather's impacts on lives and livelihoods. This precipitation forecast has a lot do with La Nia, which has already started to settle in. 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. 16 day. A first look at Winter 2022/2023 forecast shows an obvious influence of the third-year La Nina phase. Again, you can see more snowfall than normal, covering a large area from western Canada down into the northwestern United States and the far upper Midwest. Again, there is an expectation that January and February will see more of an influence from the Atlantic, with the ECMWF maps indicating near-average precipitation levels for most of the UK. All good scientific studies note their limitations, and this analysis carries some caveats that are familiar to most climate scientists. Get The 7 DMV newsletter in your inbox every weekday morning.

All I can say is that I don't have any reason to rule it out as a contributor, and I think this idea will be explored more in the years ahead. Here, I am focusing on the Southwest region south of 40 N that covers most of California, Nevada, Utah, and Arizona, in early winter (December-January). The displaced jet stream brings colder temperatures and winter storms from the polar regions down into the northern and northwestern United States. The next image below shows the change in the snow depth forecast between the latest model data and the previous model run. Regarding whether the increased "waviness" is linked to Arctic amplification, we do not have a scientific consensus on such a link. However, December may put the brakes on this, with a strong signal for this month to be much cooler than average. The most common wind direction in the UK is south-westerly though, so more often than not we get relatively mild air from the Atlantic bringing rain, rather than this cold air from the north and east which often turns any rain to snow.. 8/10: A new .

AccuWeather's 2022-2023 Canada winter forecast La Nia is expected to affect winter weather in Canada for the third straight year. This figure confirms that SPEAR simulates very high Southwest U.S. precipitation totals in December-January in at least some of the simulated winter La Nias. This year La Nia returns for the third consecutive winter, driving warmer-than-average temperatures for the Southwest and along the Gulf Coast and eastern seaboard, according to NOAAs U.S. Winter Outlook released today by the Climate Prediction Center a division of the National Weather Service. Remaining very mild. Since the ocean is the same in all the simulations, the models will produce a range of outcomes that account for the role of atmospheric chaos for each individual La Nia. Overall, the UKMO shows a decent snow season across the northern United States. Karen S. Haller. Regarding the "warm blobs" you mention, most studies suggest that extratropical sea surface temperature anomalies generally do not have a major impact on the large-scale atmospheric circulation, so I suspect that the two warm blobs you mention did not have a major impact on Southwest U.S. precipitation. The Farmers' Almanac has officially released their 2022 winter forecast. Submitted by Nathaniel.Johnson on Thu, 02/23/2023 - 17:43.

The February snow depth forecast shows the snowfall potential reducing further over most of Europe. January snowfall forecast shows a similar pattern, with more snowfall over much of southern Canada and the northern half of the United States. To better understand the ENSO changes, we produced a video showing the La Nina anomalies from Summer into Fall. Such projections reflect typical conditions that develop during La Nia events, which are associated with an episodic cooling of ocean waters in the tropical Pacific. A fast moving winter storm will bring a swath of heavy snowfall from North Dakota into northern Missouri beginning this evening. NOAA forecasters, in collaboration with the National Integrated Drought Information System (NIDIS), continue to monitor extreme, ongoing drought conditions that have persisted in the Western U.S. since late 2020, as well as parts of the central U.S. where historic low-water conditions are currently present. Warmer and drier winter weather prevails over the southern states. Surprisingly to me, the SST correlation pattern did not project strongly onto the mean La Nina SST anomaly pattern, as one might expect if the dominant effect was a linear amplitude effect. Are you Weather-Ready for spring hazards?

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. With temperatures so warm winter and the chance of snow feel somewhat distant. Empowering people with actionable forecasts, seasonal predictions and winter weather safety tips is key to NOAAs effort to build a more Weather- and Climate-Ready Nation. Several inches of wet snow are likely. More snowfall is also seen over parts of the upper Midwest. AccuWeather's range for the Twin Cities is 75-124% of normal, which means it could be below average or above average. The circulation of the strong high-pressure system promotes the development of a low-pressure region over Alaska and western Canada. We did have a high-amplitude MJO phase 3, which often leads to wet conditions on the West Coast. The pattern in the map is very weak, with very small departures between the two groups. 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. CPC Outlook for Winter 2022-23: The overall forecast for West Central and Southwest Florida for the upcoming winter is for a better chance of above normal temperatures and below normal rainfall as can be seen in the Climate Prediction Center Winter Outlook graphics below.

(NOAA Climate.gov, using NWS CPC data) Download Image Temperature But note more snowfall potential remains over the u pper Midwest. We cannot rule out the possibility that the model is missing some sort of predictable connection between a particular flavor of La Nia sea surface temperatures and Southwest precipitation. Ideas and explanations found in these posts should be attributed to the ENSO blog team, and not to NOAA (the agency) itself. The Old Farmers Almanac is predicting a divided nation with harsh winter in the East and mild weather in the West. This would likely bring a risk of chilly nights with mist, frost and fog in places, with some snow possible in any showers in northern and western areas, especially over high ground.. The changes in the jet stream certainly have impacted conditions over the U.S. this winter. ), and I have seen that there are a few studies that point to processes around Antarctica that could be contributing. Warmer than normal weather and mild winter conditions typically develop over the southwestern United States, eastern United States, and eastern Canada. The rest of the United States shows less snowfall than normal, but that does not mean no snow at all. This winter it seems the temps were fairly uniform across the equator. According to Flagstaff NWS website they gave so far had 146.7" snow this winter which blows away the previous record. What does the latest ocean analysis data show, and what influence did it play on temperature and snowfall patterns in the past? The storied old journal's extended weather forecast predicts "plenty of snow, rain and mush as well as some record-breaking cold temperatures! NOAA Climate.gov image, based on precipitation data from NOAAs Precipitation Reconstruction over Land (PREC/L). 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. air travelling from north to the south) bring the air straight from the Arctic and over a cold sea to reach the UK. below-average surface temperatures in the central and eastern equatorial Pacific, signal relative to the noise of random weather variability, Stratospheric warming due to Tonga volcano, https://www.washington.edu/news/2022/10/03/study-suggests-la-nina-winte, Southeast Colorado and Northeast New Mexico.
