December 2025 OBS and Discussion

Looks like Friday's frontal passage (timed for around 0900h EST) could lead to a few hail or snow showers with rapidly falling temperatures? It would be around 45F before the front goes through and low to mid 30s by afternoon in W-NW winds gusting to 35 or 40 mph. Lots of ups and downs in temperature trends now to end of the month, it looks likely to average near normal so the current large negative anomaly would be essentially cut in half (balanced by a zero anomaly for half a month). But it looks very cold near the end of the current GFS run by NYE-NYD.

That west coast trough crashing in after Christmas will lead to that massive and near record warm ridge over central US to eventually move towards east coast. Hopefully it’s transient, but Central and south US will really torch Christmas week
