DISCUSSION

Issued at 1242 AM EST Mon Dec 15 2025

A very cold air mass is in place as high pressure sits overhead. In the upper levels, a trough remains over the Eastern U.S. and a ridge is over the Western U.S. A warming trend begins Tuesday as a weak ridge moves into the Southeast and high pressure moves to the east bringing southerly flow to the region. Monday through Wednesday will be dry and temps will return to near normal by Wednesday. Rain is likely Thursday as the next system approaches with a cold front moving through Thursday evening and a strong shortwave passing by Friday morning. A changeover to snow is likely late Thursday night mainly in the mountains as the trough moves through, then northwest flow brings a terrain enhancement factor. Strong winds in the mountains and foothills will be possible Thursday/Thursday night with a wind direction favorable for downslope but may stay below Advisory criteria of 40 mph.

Friday and Saturday look dry with high pressure and nearly zonal flow. After a post frontal cooldown on Friday, temps will rebound quickly to above normal on Saturday.
