DISCUSSION

Issued at 1240 AM CST Thu Dec 18 2025

Warm advection will continue into the day today ahead of an approaching cold front. A lead shortwave disturbance crossing the northern Gulf this morning will see continued chances for light showers moving north through the morning, with a more organized chance for showers and a few thunderstorms arriving this afternoon and evening with forcing along the cold front and with that deeper shortwave's arrival.

After the trough axis moves east tonight, rising mid-level heights and arriving surface high pressure should clear out clouds and rain for Friday. Frost and light freeze conditions are possible the for parts of the area the next two nights. Then the pattern becomes more zonal aloft and transitions to ridge dominant by midweek as a 590 dam H5 ridge builds over the Rio Grande valley and pivots east along the Gulf Coast through mid week. Slight rain chances Saturday night/Sunday with a northern stream shortwave and into the first part of the new week will be associated with weak forcing and transient moisture passing through the region. Rain amounts will be limited where measurable.

Of interest, the 7-Day forecast includes high and low temperatures pushing about 15-20 degrees warmer than normal for late December as we move into the Christmas Eve/Day holidays. A white Christmas is not expected, but Santa his reindeer may enjoy a more tropical experience passing through the region next week. /NF/
