That part of the country also is expected to receive less snow than normal. Can MJO interfere with ENSO climate? Thanks Nat for this cogent and readable discussion! Starting with the seasonal average for Europe, we can see another weak snowfall forecast similar to the ECMWF. 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. It was also noticeable that most mediterranean-like climates in both ( North and South) hemispheres had shown early signals of drought in December-January Projections from last year , the coupling of a negative ENSO and negative PDO with Negative IOD brings limited number of Lanina years with such combined wet-dry phases during a particular ENSO ( cold or warm ) . To better understand the ENSO changes, we produced a video showing the La Nina anomalies from Summer into Fall. This precipitation will either be rain or snow, depending on just how cold the air is, and where the freezing level is. So, I did not see any obviously linear effect of La Nina amplitude in the observational analysis. In this blog post, I hope to get this conversation rolling! We have seen a stronger-than-normal jet stream throughout the Southwest, which has brought the wetter conditions this winter. It calls for snowfall to be above normal toward the East Coast as well. Submitted by Matt on Thu, 02/23/2023 - 11:44. The December snow depth forecast shows less snow cover over most of the United States and Canada. Cloudier on Wednesday with outbreaks of rain and possibly snow, alongside strengthening winds.

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. 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. Farmers' Almanac predicts Michigan winter with plenty of snow, cold Of course, as with all these predictions, they are just indications of the long-range patterns. 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.

This winter it seems the temps were fairly uniform across the equator. Due to arctic amplification (or not) the jet steam has been "wavy" this winter bringing colder than average temperatures to the SW (I live in Tucson) and unusual warmth to the east. Unfortunately, a dry winter is predicted for the Southwest states, which won't help the drought situation. Maximum temperature 7C. This connection has been hypothesized, but the evidence is mixed. We see an equal-to-higher probability for more precipitation (and snowfall) over the northwest, extending into the Great Lakes and the eastern United States. 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. Perhaps more relevant for this discussion, the teleconnections forced by the MJO also can interfere with those of ENSO. The more forecast data you can look at, the better idea you can get about the expected weather patterns. Thank you for the immense and informative analysis . Based on the Farmer's Almanac winter 2022-2023 predictions for the upcoming chilly season, the report shows that . I am wondering if there is a possibility that the triple-dip La Nina event from 2020 could create some kinds of conditions that make atmospheric rivers more active, resulting in the occurrence of torrential rains over the western United States. For completeness, I will mention that there are other potential sources of seasonal predictability, such as stratospheric, cryosphere, land surface or radiative forcing variations, but sea surface temperature variations generally are the most important. Instead, the pattern looked a bit more like the positive phase of the Pacific Meridional Mode. This can be as low as 200ft or so above sea level on some days, the Met Office explains. I also have noted that the tropical atmosphere has been more persistently La Nina-like than the Nino region sea surface temperatures in recent months. 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.

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. This is only the 2nd time there has been above normal winter rainfall, Submitted by Craig T on Thu, 03/02/2023 - 08:09, In reply to jet stream by Nathaniel.Johnson. Probably the coupling of weak Polar vortex with the recurrent PV stratospheric warming has something to do with the Southward (equator-wise) migration of Atmospheric wet Rivers in mid to late winter , this last point is well-documented in many physical science papers that weak polar vortex post SSW events tend to measure more equator-wise migration of the Jetstream causing these atmospheric rivers to bring wetter than normal events to California and many mediterranean-like climates in the northern hemisphere late winter. The effects of air rising up hills and mountains must also be considered. By January, most of the country is mild, with lower temperatures farther north and a serious chill entering the Upper Midwest and Great Lakes region by February, while the Southeast especially toward Florida, warms up.

Seasonal Forecast for February - April 2023. That's a good point! It will modify the jet stream pattern over North America and the Pacific Ocean, extending its reach to the rest of the world. The problem with this approach, however, is that our record of reliable observations is just too short to slice and dice the data in this way. 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. While December was above-average as far as the temperature goes, January was a different story. More early Spring snowfall is also expected over the northwestern United States and the southern half of Canada while the La Nina influence slowly lets go. A first look at Winter 2022/2023 forecast shows an obvious influence of the third-year La Nina phase.
