.DISCUSSION...
Issued at 126 PM CST Mon Dec 22 2025

Through next Monday: Low-moisture and weak isentropic ascent will
persist through this evening, supporting varying cloud coverage with
the possibility for isolated light showers across the area.
Currently, mid to upper 60s dewpoints extend to the I-20 corridor.
These conditions are being driven by surface high pressure becoming
wedged into the Lower Mississippi Valley from the east, while quasi-
zonal flow aloft remains in place across the area through much of
the period, with ridging aloft building in late in the work week. As
the surface high becomes the dominant feature of the period beginning
Tuesday, leading to a dry conditions with a period of above average
temperatures heading into Christmas day. High temperatures daily
will generally reach the mid to possible upper 70s daily, while
overnight lows cool into the low to mid 50s through Saturday.

By the weekend, the approach of the next front from the northwest
looks increasingly likely, along with the return to colder
conditions and increase to rain chances./KP/

.AVIATION...
(06Z TAFS)
Issued at 1124 PM CST Mon Dec 22 2025

Clouds will continue to plague area TAF sites overnight into
early Tuesday morning. However this time, flight categories will
vary from VFR to IFR as ceilings won`t be as consistently low
across the area as they`re been the past few night. As high
pressure builds into the region from the east Tuesday, subsidence
will cause clouds to steadily erode and light north of the region.
This will allow flight categories to improve to VFR levels
areawide by late morning, and continuing through the remainder of
this 06z forecast period. Winds overnight will be calm to light
from the south between 3-5 knots. Some patchy fog will be possible
at namely KHEZ, KHBG, & KPIB around day break Tuesday, which
could periodically cause visibilities to drop to MVFR levels. Any
fog that does develop will quickly begin eroding shortly after
sunrise. Winds by late Tuesday morning will become sustained from
the west southwest between 5-10 knots, and will persist through
the afternoon hours. /19/
