.SHORT TERM...
(This evening through Monday Night)
Issued at 248 PM CDT Sun Mar 9 2025

Some wraparound clouds continue across most of southeast TX this
afternoon as the main upper-low moves overhead and continues to
track east this afternoon/early evening. Skies will gradually
become mostly clear late this afternoon as drier and cooler air
filters in and the main low moves out of the region. Northwest
winds will also weaken this evening as pressure gradient relaxes.
Mostly clear skies and light winds will result in good radiational
cooling with overnight lows in the mid 30s to mid 40s.

Surface high builds over the southern Plains tonight, bringing a
pleasant start to the work-week. Highs will generally be in the
70s under light to occasional moderate winds. Winds will
gradually transition to the west, then south as the surface high
shifts to our east by late Monday afternoon and evening.

.LONG TERM...
(Tuesday through next Saturday)
Issued at 248 PM CDT Sun Mar 9 2025

This period begins with the return of onshore flow and a warmup.
Will see max temps warm from the 70s on Tuesday to around 80 on
Wed and then into the mid 80s with some upper 80s across W/SW
areas on Thu/Fri. We will see a mid/upper level trough move across
the southern Plains on Wednesday and am expecting some
thunderstorm development during the late aft and evening hours
across northern areas of SE Texas due to this feature coupled with
daytime heating. A second storm system will track across the
Plains on Friday. An associated surface front should move into the
region Friday night bringing with it another chance of
thunderstorms. Expecting to see about a 10 degree cold down behind
this cold front over next weekend.
