Clear skies most of the night and early today with some cirrus
arriving now in deep eastern TX and near Shreveport with more to
come out of central TX for the day ahead. Temps are chilly for
late March and still on the fall. We have a handful of upper 30s
north of I-20, and low to mid 40s along and to the south. Many
sites are calm, but a light N/NE is also well represented. Our 88D
VAD winds are shallow NE at 20KT at 1kft and back to east at 2kft
and then S/SW flow aloft. SFC high pressure extends down the MS
River Valley and almost no gradient over AR or MO. Our highs today
will be similar to those we experienced yesterday. The 1024mb
core is over the Dakotas and will be sliding eastward underneath
the parent low pushing off the lakes into Canada.
There is a weak surface low over W TX and a little upper level
turning in the back corner of the upper trough over OK/TX. Our
dew points are pretty low, having stabilized in the mid to upper
30s. We will be seeing some light frost where the mid 30s end up
in a few hours north of I-20. The TX clouds will be spreading in
ahead of that weak surface low and upper impulse, but just not
enough moisture for any precip except for some of our TX counties.
The SPC has maintained a general TS line across eastern TX from
Mount Pleasant down to Toledo Bend country. Isolated showers or a
thunderstorm will be possible during this evening.
So look for one last chilly night and still some patchy frost in
S AR tonight with 36 the coldest low at El Dorado. The last of
these upper 30s and lower 40 will move east with the high pressure
after tomorrow. The NE winds will remain light and shift to E/SE
early tomorrow with warmer lower 70s bringing us back to average.

.LONG TERM...
(Thursday Night through Wednesday)
Issued at 300 AM CDT Wed Mar 27 2024
Weak high pressure spreading down along the Gulf coast will
continue eastward during Friday. This will help out with our area
seeing further warming to end the work week. Friday and Saturday
will see the wind speeds increasing and veering around to S/SW
with well above average temps still dominating the pattern through
Easter Sunday and even into next work week. Lows will tag along
with 50s and then 60s to end this long term. Our next cold front
will be arriving on Tuesday with another half inch to inch of
timely spring rainfall and our first of many April showers. /24/

VFR conditions across the airspace this morning as mid and high

will vary through the period before what appears to be the return
of SKC at the end of the of forecast, spilling into the next TAF
cycle. Light VRB winds will exist across the area terminals
through the period with a transition to more north-easterly winds
by the end of the TAF package. Terminal wind speeds will range
between 3-5KT, with some falling to calm at times.
