A series of upper level disturbances coupled with a cold front will bring several rounds of showers and thunderstorms to Southeast Texas beginning late Tuesday night or very early Wednesday morning and again late Wednesday afternoon and evening.


An upper level disturbance will approach the region from the southwest late Tuesday night. This disturbance will bring showers and thunderstorms to Southeast Texas. Conditions with these storms look favorable to produce large hail and brief but locally heavy rain. The disturbance will exit the region around noon.


Timing: Wednesday morning 4 AM to Noon
Confidence with the first event is moderate to high.
A second disturbance coupled with a cold front will trigger a second round of showers and thunderstorms toward evening. This episode of storms could also produce severe weather with strong damaging winds as the primary severe weather hazard.

Timing: Wednesday 4 PM to 11 PM
Confidence with the second event is low to moderate.


Alternate Possibilities
Like Saturday night, a few of the models show capping in place for the second event which will limit the convective potential.
Cloud debris from the morning storms may limit heating and lower the threat for active weather in the afternoon.

…Severe Weather Risk for Wednesday Evening…
…Gale Watch in effect for Wednesday Night…

A strong late season cold front will rapidly push south across the Middle Texas Coastal Waters Wednesday Night. A period of strong to very strong north flow is likely to occur in its wake. Gale conditions will be possible across the Offshore waters of the Middle Texas Coast and possibly the Nearshore waters off Padre and Mustang Islands. The worst winds should be over by sunrise Thursday.


A rapidly moving line of showers and thunderstorms may develop near the Victoria area early Wednesday evening and strengthen as it pushes south across the Coastal Plains. Strong to severe thunderstorms will be possible along this line, if it develops, with the greatest threat of severe weather currently expected to be across the Coastal Plains and Gulf waters.

Forecast & Impacts:

Marine Wind:

Becoming north sustained 25 to 30 knots across area bays and adjacent nearshore waters.
Sustained north 30 to 35 knots with gusts around 40 knots across offshore waters.
Strongest winds from late evening until late in the night.


Seas will rapidly build to 6 to 8 feet across the nearshore waters and 9 to 12 feet across the offshore waters.
Bays will become rough to occasionally very rough.

Operating a vessel in gale conditions requires experience and properly equipped vessels.
The Gale Watch is intended to provide additional lead time for mariners who may wish to consider altering their plans.
It is highly recommended that mariners without the proper experience seek safe harbor prior to the onset of gale conditions.
Severe Weather:

A line of thunderstorms may develop across the Victoria area towards sunset and rapidly shift south during the evening.
If the line develops, it may strengthen as it moves across the Coastal Plains.
Strong to severe thunderstorms will be possible as the line develops.
Strong straight-line winds, large hail, and frequent lightning will be the primary storm threats.

Area of Concern:

Hill Country and along and east of the I-35 corridor.

Threats & Impacts:

Winds: Damaging straight-line winds in excess of 60 mph possible.

Hail: Hail 1-2″ in diameter possible.

Rainfall: 1/4 to 1 inch with isolated pockets up to 2 inches


Timing and Overview:

Not too many changes in the models since yesterday. An upper level system and associated surface cold front will bring a chance of storms to portions of South Central Texas Saturday evening and overnight. A few isolated storms could be possible near and east of I-35 as early as Saturday afternoon. However the best chance of storms will come between 8 PM and Midnight Saturday evening across the Hill Country and I-35 corridor and 10 PM to 2 AM east of I-35. Some storms will be capable of producing large hail and damaging straight-line winds. The Storm Prediction Center continues to place portions of the area in a Slight to Enhanced risk for severe storms for mainly Saturday night.

In addition, frequent cloud to ground lightning will be possible. Due to the progressive nature of this storm system the threat for widespread heavy rainfall and flooding is minimal. Rainfall amounts will average 1/4 to 1 inch. A few pockets of 1-2 inches of rainfall will be possible east of I-35 and north of I-10. Much lesser amounts of rainfall will occur out near the Rio Grande.
