DISCUSSION

Issued at 124 AM CST Mon Dec 22 2025

Today through Sunday...The frontal boundary that sank south through the forecast area Sunday, now resides along the north central gulf coast this morning. Despite this boundary being south of the area, little to no appreciable airmass change has, or will, occur across the region as it "washes out" through the day. This will allow for moisture, along with warm conditions, to remain across the region through the forecast period. This is as a result of high pressure at the surface becoming wedged into the Lower Mississippi Valley from the east and quasi-zonal flow aloft generally remaining across the area through much of the period, with ridging aloft building in late in the work week.

For today, isentropic upglide across the region will continue to yield an abundance of cloud cover, along with isolated to very scattered light showers across the forecast area this morning into the afternoon hours. Fortunately though, the day will not be a complete washout by any means, as much of the CWA looks to remain dry. Locations that do see rainfall will only see very light amounts as totals remain less than a tenth of an inch.

The aforementioned surface high will strengthen across the region from the east on Tuesday, and will remain a fixture across the region through the Christmas holidays and into the final weekend of 2025. This will bring an end to rain chances through much of the remainder of the forecast period, but it'll bring about the warmth across the CWA in the process. Well above normal conditions will exist across the entire forecast area during this time. Temperatures overall will be some 10-20 degrees warmer than their norm for this time of year. Daytime highs will top out in the low to upper 70s through Saturday, with unseasonably mild lows as they only fall into the 50s to around 60.

A return to colder conditions, along with an increase in rain chances, currently looks to be on the horizon come Sunday. This is when a cold front is advertised to move into and through the forecast area. /19/
