Given the distribution of snowfall anomalies, it shows a likely low-pressure zone over northwestern Europe. We see more snowfall over the northwestern and northern United States and southern Canada. In the West, the drought persists. 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. When we divide up the observed record even further, e.g. 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. The Farmers' Almanac has officially released their 2022 winter forecast. With CAGRs of 17.4% and 12.7%, respectively, over the past 10 years. To better understand the ENSO changes, we produced a video showing the La Nina anomalies from Summer into Fall. However, there is another way which requires very little wind at all high pressure that becomes established across the UK for a long time in winter. Thank you, Clara, for the kind words! We have also produced an image that shows the snowfall forecast change compared to the forecast from the previous month. 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.

The Met Office's three-month outlook, for example, suggests this winter is half as likely as usual to be classified as wet. Ultra long range detailed weather forecast for South England. Not sure how much that was a factor. Another meteorological winter is drawing to a close, though it feels like some of us in the East are still waiting for winter to arrive (not a single inch of snow here in central New Jersey so far!). No cold event has gone into the 4th year in the known records, so it is expected that we will see the last La Nina phase this season for a while. Want to know how your actions can help make a difference for our planet? 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. As always, we start with the ECMWF, the most often used and highly regarded seasonal forecasting system. Warmer than normal weather and mild winter conditions typically develop over the southwestern United States, eastern United States, and eastern Canada. Its interesting to note that the La Nia dry signal over the Southwest U.S. appears to be a little more robust in February-March than December-January, as 15 of the 21 events classified as La Nia in December-February had drier-than-average conditions in February-March. December-February: January-March: The effects of air rising up hills and mountains must also be considered. 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. Percent of normal U.S. precipitation over the past 30 days (December 25, 2022, through January 23, 2023) after a series of weather events known as atmospheric rivers, fueled by tropical moisture, flooded the U.S. West with rain and snow. 8/10: A new . 10 day.

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. But now, we will look at actual Winter snowfall predictions from the latest forecast models. According to the Old Farmer's Almanac, winter will arrive early this year for the province, with frigid temperatures dropping down from the Yukon and northern Alberta by mid-to-late November. 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). Farmers' Almanac predicts Michigan winter with plenty of snow, cold The MJO certainly can interfere with ENSO, particularly during development of ENSO through the MJO influence on tropical westerly wind bursts. During this period, the prevailing winds continue to blow from the northwest or northeast. Drier-than-average conditions are forecast in portions of California, the Southwest, the southern Rockies, southern Plains, Gulf Coast and much of the Southeast.

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. 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. Looking at the winter predictions for 2022-2023, there may be some weather you need to look out for. We did have a high-amplitude MJO phase 3, which often leads to wet conditions on the West Coast. It says that temperatures there could drop 4 degrees below normal for the month something that could result in a damaged citrus crop and stunned iguanas. Patchy cloud with some clearer skies. The next update will be available November 17. The circulation of the strong high-pressure system promotes the development of a low-pressure region over Alaska and western Canada. I follow that convention here, though Im really calculating the inverse, meaning the noise-to-signal ratio. This connection has been hypothesized, but the evidence is mixed. Most of Europe is forecast to have less snow depth by mid-winter. Three events went neutral in the third year, and three phases shifted into an El Nino in the third season. But take note of the trough of equal temperatures probability extending down low into the south-central states. More U. S. drought in a second-year La Nia? 7 day.

How unusual were these Southwestern wet conditions in the first two-thirds of a La Nia winter? NOAA Climate.gov image, based on precipitation data from the NOAA GFDL SPEAR climate model. This is calculated as the deviation of the 30 ensemble members from the average for each individual La Nia event, and so I wind up with a total of 630 deviations from the ensemble average that capture precipitation variations resulting from the uncertainty in the initial conditions, i.e., chaotic weather variability. The seasonal outlook looks at temperature and precipitation trends between December 2021 through February 2022. 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. Winter storm conditions forecast from Montana to Michigan; California 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.

From February to April, above-normal temperatures are projected to continue along the East Coast, in the Southeast and into the Southwest, with the greatest chance of warmer weather along the. C) and did not see any substantial differences than when I considered all La Nina episodes. With the observations, I did try setting a higher La Nina amplitude threshold (DJF Nino 3.4 SST anomaly amplitude greater than 1 deg. The relief from an unrelenting drought was welcome, but too much of a good thing also meant flooding, mudslides, and dangerous debris flows. 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. Light winds. Meanwhile, the southern U.S. is expected to have a.

Also, the southwest is expected to be dry during the winter months, which won't help the drought. ) or https:// means youve safely connected to the .gov website. Largely cloudy for all during the afternoon but remaining dry. The data shows that the La Nina jet stream pattern also changes the snowfall patterns over North America as the pressure systems take a different path, along with the cold air. The January snow depth forecast shows a similar pattern of more snowfall from western Canada into the northwestern United States. It looks like an interesting study, and it relates to last month's blog post on the discrepancy between observed and modeled Pacific sea surface temperature trends. NOAA releases winter weather predictions: Here's what to expect - FOX40 Northerly winds (i.e. It will modify the jet stream pattern over North America and the Pacific Ocean, extending its reach to the rest of the world.
