DISCUSSION

Issued at 100 PM CST Sun Dec 14 2025

The near term forecast is right on track for the forecast area with very strong cold advection ushering in arctic air with strong northerly wind gusts and low wind chills. No changes are being made to the cold weather advisory and messaging for low wind chill and temperature readings going through tonight into early Monday. Wind will diminish tonight, but the cold anomalies will peak at about daybreak Monday morning. Thereafter, the cold air mass will slowly modify and temperatures moderate as the the surface high shifts across the area Monday into Monday night, although Monday night will see temperatures dip back well into the 20s. /EC/

Early week into next weekend (Tuesday-Saturday): Synoptic flow will gradually shift westerly through mid to late week in advance of a deepening spoke of vorticity diving into the Sierra Madres. As low-level ridge shifts east, warm advection and moderation will be the norm. There could be an opportunity for some light rain around mid week and scattered coverage of rain and storms Thursday through early Friday. We will probably need to monitor some storm potential with the front around Thursday, as there could be some mean deep layer shear (30 to 50kts) and subtle mid- level lapse rates for some stronger convection. Synoptic amplitude details are coming in alignment, so confidence is a touch improved from yesterday. /DC/
