Area Forecast Discussion
National Weather Service Brownsville TX
338 AM CDT Wed May 3 2017

...Strong to Severe Storms Possible This Evening and Tonight...

.SHORT TERM (Now through Thursday): Shortwave digging into the
Plains sends a cold front south across Texas today and through the
Rio Grande Valley over night. Strong to possibly severe storms
possible along and ahead of the approaching cold front this evening
and tonight.

This morning and afternoon: Mostly cloudy skies this morning will
slowly break across the western zones first and then across the
coastal areas later in the day as drier air pushes in from the
west/southwest. Temperatures closer to the coast will top out in the
upper to lower 90s. Across the western zones, temperatures become a
little more tricky with triple digits not out of the question.
Surface winds start out more southerly during the morning before
shifting to the west and northwest during the afternoon hours, while
850 mb winds remain southwesterly and 700 mb winds shift from the
southwest to the west. This will serve to bring in warmer and drier
air off the Mexican plateau and could allow temperatures to spike.
850 mb temps match up well with this scenario and the 24C to 25C
values should translate down to the 100F to 104F range at the
surface. As far as pops between 12Z and 00Z have toned them down a
bit, leaving just a slight chance of some morning sea breeze
convection and possibly some streamer showers.

This evening and tonight: Minor timing differences remain in arrival
of front and associated convection this evening and tonight, with
the bulk of the action expected between 03Z and 09Z. A line of
storms is expected to develop along and ahead of a cold front as it
pushes south across Texas, moving quickly across the northern
ranchlands between 03Z and 06Z and through the lower Valley between
06Z and 09Z. Given convective mode, abundance of CAPE, steep lapse
rates, dry air in the midlevels, expect strong wind gusts of 60 mph
or higher to be the main concern, though large hail cannot be ruled
out especially in any discrete cells that develop. SPC has placed
much of the CWA in a marginal risk for Day 1. Stronger activity will
bring periods of heavy rainfall, but believe flooding threat is
minimal given the fast propagation of the activity. Maintained
likely pops across the eastern counties and coastal waters, where
best moisture and forcing will be. Have kept POPS diminishing
quickly behind front with just a small sliver remaining over the far
southern offshore Gulf waters after 12Z.

Thursday: Behind the front breezy northerly winds will diminish
during the morning hours, with the exception being the coast, where
stronger winds are expected. Drier air filters in bringing mostly
clear skies by the afternoon. Near normal temperatures expected.

.LONG TERM (Thursday Night through Tuesday): Dry northwest
flow aloft and surface high pressure across Texas will provide very
pleasant conditions across the region through the weekend.
Thursday night will be cool with low temperatures ranging from the
mid to upper 50s inland to the lower 60s near the coast, which is
five to ten degrees below normal. Surface high pressure will
spread across the area with limited cloud cover, light winds, and
near normal temperatures expected for Friday and Saturday, as a
strong 500 mb level ridge moves overhead. Southeast return flow
will develop on Saturday as surface high pressure slowly shifts
east. A warming trend begins Sunday with increasing cloud cover.
The mid level ridge overhead will move very slowly Sunday through
Tuesday. Surface high pressure across the Gulf will continue to
support moderate southeast winds, even breezy by Tuesday. Partly
cloudy skies with near normal temperatures will prevail through
early next week. A slight chance of sea breeze convection is
possible across Deep South Texas by Tuesday. Otherwise, rain free
conditions expected to across area through the period.

&&

.MARINE (Now through Thursday): Moderate winds and seas will
continue through the afternoon hours ahead of an approaching cold
front. Small craft exercise caution will be needed for all lower
Texas coastal waters today, with winds in the 15 to 20 knot range
and seas building to 6 feet across the offshore Gulf waters. Tonight
will feature a line of thunderstorms and a frontal passage. Some of
these storms could produce thunderstorm wind gusts of 34 knots or
higher. Winds shift to the north around 06Z for the northern waters
and should be well south and offshore by 12z. Strong northerly winds
develop with gusts just below gale force and seas quickly build in
response. Have posted a Small Craft Advisory for winds for the
Laguna Madre from 03Z Thursday through 18Z Thursday and a Small
Craft Advisory for the Gulf waters from 03Z Thursday through 00Z
Friday.

Thursday Night through Sunday Night...Marine conditions will
gradually improve Thursday night into Friday as north winds diminish
and seas subside. North winds Friday will shift to east Friday night
as high pressure spreads over the area. Very favorable marine
conditions will prevail along the Lower Texas coast on Saturday with
light southeast winds and low seas. Southeast winds will increase
and become moderate on Sunday, with seas building to moderate.
