.UPDATE...
Issued at 919 AM CDT Wed Mar 27 2024

Another beautiful, spring day is underway across the region in the
wake of Monday`s frontal passage. A weak shortwave will transit
the area this afternoon with enough moisture to increase cloud
cover, but no precip is expected. The inherited forecast reflects
this and no changes were made this morning.

.SHORT TERM...
(Today through Friday night)
Issued at 305 AM CDT Wed Mar 27 2024

Early morning surface analysis shows high pressure extending from
the northern Plains to the forecast area while aloft, a large
mid/upper level trough is dominating the central CONUS. Surface
high pressure will continue to build south across the CWA today,
resulting in another very pleasant day areawide. Aloft, the
central CONUS trough will gradually shift eastward today, with the
trough axis eventually becoming situated overhead. As this occurs,
a shortwave in the flow aloft will induce shower activity over
central TX. Although this activity is not expected to make it
into the forecast area it will bring some additional cloud cover
to the region today, which along with the drier/cooler airmass
overhead will keep temps in the mid 60s to low 70s.

The remainder of the work week will consist of dry conditions and
mild temps as surface high pressure traverses the region and
departs east by early Friday. Temperatures will top out in the low
to mid 70s tomorrow and in the mid to upper 70s on Friday thanks
to the return of onshore flow. Overnight, lows will fall into the
mid 40s to mid 50s tomorrow night and in the low 50s to low 60s by
Friday night.

.LONG TERM...
(Saturday through Wednesday)
Issued at 305 AM CDT Wed Mar 27 2024

An exiting mid to upper level trough off the East Coast and a
deepening mid to upper level trough over the Western U.S. will keep
a zonal flow aloft for our region Easter Weekend. For our area,
surface high pressure over the Southeast U.S. with a deepening
surface low over the TX/OK Panhandles will keep a tight pressure
gradient over the area, resulting in breezy southerly winds over
Easter Weekend. No significant upper level disturbances or lift is
expected to generate any significant precipitation, although
expecting increasing cloudiness for Easter. Low temperatures
Saturday morning in the lower 50s Central Louisiana to lower 60s
over Southeast Texas. Highs both Saturday and Sunday in the lower
80s, with lows Easter Sunday morning in the upper 50s Central
Louisiana to mid 60s Southeast Texas.

Monday through Wednesday will have the approaching mid to upper
level trough from the Western U.S. keeping southwest flow aloft over
the region. It gets a little complicated as latest extended runs
shows a possible cut off low stalling over the Southwest U.S. with
intermittent upper level impulses ejecting northeastward, which
brings less confidence in the forecast. Blended guidance continues
to show about 20-30% chances of showers north of I-10 by Tuesday and
Wednesday, with a possible cold frontal passage on Wednesday. For
Monday and Tuesday, even warmer temperatures expected with lows in
the mid to upper 60s, and highs in the mid to upper 80s. By
Wednesday, slightly cooler temperatures possible if the cool front
moves through.

.AVIATION...
(18Z TAFS)
Issued at 1228 PM CDT Wed Mar 27 2024

Breezy North to North Northeasterly winds will continue through
the afternoon due to the taut pressure gradient between a cold
front along the East coast and High pressure building south across
the southern plains. VFR conditions will prevail through the
period with SCT to BKN high clouds continuing to stream across the
region through evening as a weak shortwave transits the region
before clearing early Thursday morning.

.MARINE...
Issued at 305 AM CDT Wed Mar 27 2024

A brief period of breezy north winds can be expected later this
morning before winds start to relax through the afternoon as high
pressure settles overhead. Light to moderate north winds then
continue through tomorrow before gradually become southerly
tomorrow evening into tomorrow night as high pressure departs to
the east. Light to moderate onshore flow will then continue until
the passage of a cold front next week near the end of the forecast
period.
