This latest forecast cycle interestingly shows more snowfall over the western United States and also the Midwest. 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. Images by NOAA Physical Science Laboratory. Below we have an Official NOAA CPC probability forecast graphic, which shows the long-range forecast of the central ENSO region.

That doesnt mean that the different flavors of La Nia cannot be important for Southwest U.S. precipitation, and its worth trying to better understand the simulated La Nia precipitation variations. 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. 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. We are currently in a La Nina phase, entering its third and final year, likely being replaced by a warm phase for 2023/2024. Submitted by Matt on Thu, 02/23/2023 - 11:44.

Conditions will be particularly cold through the middle of the month, with widespread frosts and a risk of wintry showers, even to low levels in some cases. This figure indicates that SPEAR produces very wet early winter conditions in the Southwest for some of the La Nia simulations, with the largest differences between the wet and dry groups exceeding twice the 1991-2020 climatology (more than 200%). As far as ENSO goes the one difference this winter seems to be the east tropical Pacific was not as cold as the prior years when the SSTs in the Nino 1.2 at times were from -2 to -.2.5 while the western tropical pacific was near neutral.
