Area Forecast Discussion

1242 PM CDT Thu May 25 2017

.DISCUSSION...
For 18z TAF issuance.

.AVIATION...
Fairly straight forward forecast today with strong srly winds
being the main issue through the period. Sfc obs show elevated
winds already ongoing as the region lies between high pressure
centered over the n-cntl Gulf and low pressure over the Plains.
Looks like the gradient is expected to remain tight through the
period despite the sfc ridge pushing ewd, while forecast time-
height sections indicate slightly stronger flow aloft for tomorrow
which will help speeds run even higher tomorrow. Otherwise limited
moisture noted which should keep clouds scattered at most.

.PREV DISCUSSION... /issued 1101 AM CDT Thu May 25 2017/ 

UPDATE...
Light southerly flow already returning across the area
as surface high pressure  shifts off to the east. A few
clouds above 3000 feet continued to ride the leading edge 
of moisture return. No changes needed to forecast other than to
tick up a few more low clouds. No significant changes...therefore
let the forecast ride.

PREV DISCUSSION... /issued 631 AM CDT Thu May 25 2017/ 

AVIATION...Southerly winds will become reestablished today with 
high pressure advancing east of the area. While the southerlies
will bring a gradual increase of low level moisture, the mid and
upper levels will remain dry on a continued northwest flow. 
VFR to prevail.

PREV DISCUSSION... /issued 335 AM CDT Thu May 25 2017/ 

DISCUSSION...
Weather map depicts upper low centered over the mid MS River
valley this morning with northwesterly flow situated across the
area. Surface ridge is currently along the Sabine River with
generally clear skies. Temperatures away from the coast are in the
low to mid 50s with temperature along the coast in the 60s.

Surface ridge will continue shifting east across the area today
with southerly and southwesterly winds returning to the area. 

Forecast remains unchanged through the remainder of the week into
the first part of the weekend. The area will continue to see a
warming and moistening trend as the storm track remains across the
central plains. Temperatures by Saturday will be approaching 90. 

Some changes to the forecast for the later half of the weekend
into next week. The front looks to be a little slower than
forecast this time yesterday, therefore rain chances were lowered
just a bit for Sunday. By Sunday night into Memorial Day the front
does move into the region with a good chance for showers and
thunderstorms. The front is forecast to hang up near the coast
with a good chance for thunderstorms through the remainder of the
forecast, especially during the daytime hours.  

MARINE...
Southerly winds will return to the northern Gulf and become brisk
at times. This will continue for the next several days.
