DISCUSSION

Issued at 134 AM CDT Thu Mar 12 2026

Our pattern will transition towards cooler and drier as troughing becomes dominant over the eastern CONUS. In the wake of the cold front this morning, winds will be gusty with tight pressure gradient. Strongest winds will occur this morning and will gradually diminish through the day as the pressure gradient relaxes later today. A surface high will settle over the region for late week and propagate eastward. As the high shifts east, weak southerly return flow will gradually increase moisture this weekend. A stout upper trough will support a rapidly deepening surface low across the plains. Its attendant cold front will be the focus for our next storm chances. Shear is strong with this system and combined with what will probably be sufficient lapse rates, wouldn't rule out a round of severe weather Sunday night. That said, timing near diurnal min, and weak moisture return leave uncertainty and possible failure modes. Of greater confidence is the tight pressure gradient associated with the cold front. Winds will likely be gusty Sunday into Monday and an HWO graphic for gradient wind will likely be needed in the near future.

Winter makes a brief return in the wake of this cold front, with lows likely near or below freezing Monday night/Tuesday morning. This is especially notable given the recent record warmth, so plants will be vulnerable. Impacts to unprotected sensitive vegetation are likely. The freeze is short lived and only expected to last one night. Temperatures will gradually warm mid to late next week with building heights over the region. /SAS/

AVIATION

(06Z TAFS) Issued at 1232 AM CDT Thu Mar 12 2026

Scattered light to moderate SHRA are lingering behind a passing cold front, but rain will taper off early this morning. In the wake of the front, northerly wind may gust into the 25-35 kt range through today. Wind gusts will subside this afternoon. An MVFR stratus deck encompasses much of the area, but it is expected to erode from west to east this morning, with VFR conditions returning areawide by the late morning hours. /DL/
