Special Weather Statement, NWS Corpus Christi, TX

Area Forecast Discussion
National Weather Service Corpus Christi TX
342 PM CDT Thu Jul 22 2021

.SHORT TERM (Tonight through Friday Night)...

Showers and thunderstorms will continue to push northward through
the area this afternoon. Some of these storms could become strong or
severe with gusty winds and small hail possible. Coverage and
intensity of storms should diminish in the evening hours with loss
of daytime heating and with the mid-upper level low continuing to
move W-NW out of South TX. Conditions should remain dry through the
rest of the period as high pressure settles in. Cloud cover will
decrease tonight into tomorrow as subsident air takes over. Lows
tonight and tomorrow night will drop into the 70s to near 80 along
the immediate coast. Expect temperatures tomorrow to warm into the
90s with areas further west reaching to near 100 degrees. Heat
indices will be in the 105-109 range tomorrow for most of South
Texas, though a few locations in the Coastal Plains could reach
values of 110.

&&

.LONG TERM (Saturday through Thursday)...

The long term remains rather quiet as upper level ridging nudges
in from the east. Much drier air will work into the region with
PWATs falling to near 1.3" over the weekend. The combination of dry
air and subsidence aloft should keep us dry through the weekend and
into early next week. Rain chances begin to trend up by the middle
of next week as ridging starts to break down while a TUTT
meanders along the Texas/Mexico border. With that said, the greatest
forcing looks to remain to our south but this renewed moisture and
potential boundary interaction will lead to a slight chance of
showers and storms, mainly Wednesday and Thursday.

Until our next shot at rain arrives, the main story over the weekend
will be the heat. We will see daily heat indices from 105-109 with a
few locations touching 110. It's possible we see a couple Heat
Advisories across the Coastal Plains as we head into next week.

.MARINE...

Moderate south-southeasterly flow is expected tonight through
Friday. Scattered showers and thunderstorms will continue through
the rest of today and will taper off this evening as a mid to
upper level low moves west through the state. There is a slight
chance of showers and thunderstorms early Friday morning. Dry
conditions will take over beginning Friday afternoon. Weak to
moderate onshore flow will continue as we head into the weekend
and early next week. High pressure aloft will keep dry conditions
intact through the middle of next week.
