Some of these storms could be severe with large hail, damaging winds and an isolated tornado or two.  This focus for Severe Weather is expected to shift eastward over the Coastal Bend on Saturday, generally east of Interstate 37.  Some models are indicating the threat for Isolated severe storms will continue on Sunday as well depending on whether the cold front moves off the coast or remains over land.

Confidence increasing for a large flood event across the region.

1. Forecast rainfall amounts of widespread 2-4 inches with isolated 8-10 inches. Heavy rains mainly north Saturday shifting south Sunday.
2. Severe thunderstorm threat mainly near the coast Saturday.
3. Coastal Flood Advisory in Effect: Forecast tide levels 3.5 to near 4 feet during high tide Friday evening and Saturday.
A slow moving strong upper level low coupled with a coastal trough of low pressure will produce widespread rain with periods of showers and thunderstorms. Storms may form bands and train over the same areas.
Friday night through Monday morning with the bulk of the heaviest rain mainly north Friday night and Saturday shifting southward Saturday night and Sunday through through Monday afternoon.
Friday and Saturday: Locally heavy rainfall and lightning mainly north of a Columbus to Conroe to Livingston line. Thunderstorms with Isolated tornadoes possible near the coast beginning Saturday morning. Coastal flooding, elevated tide levels, enhanced currents and rip currents possible.
Saturday night through Monday: Heavy rainfall threat still high and shifting southward and may see clusters/bands of slower moving storms, frequent lightning.  Severe threat (tornadoes/damaging winds) returns Sunday night/Monday morning near the coast.
Widespread rainfall totals of 2 to 4 inches are expected with locally heavier totals of 8 to 10 inches inches possible. Heavy rainfall Saturday will likely saturate the soils and additional heavy rainfall Saturday night through A Flash Flood Watch will likely be issued this afternoon.



Moderate easterly flow will continue through early Saturday. Tides will become elevated and some minor coastal flooding is possible Friday night and again Saturday night along the Bolivar peninsula. A Coastal Flood Advisory is in effect from Friday afternoon through Saturday morning.

…A Heavy Rainfall Pattern Expected Over South Central Texas for the Next Several Days…

Area of Concern:

Along and East of I-35.

Threats & Impacts:

Rainfall:  2 to 5 inches with isolated amounts over 6 inches possible.

Timing and Overview:

An upper level low pressure system will move slowly across northern Mexico and Texas today through Monday, with persistent rains expected through the period. Most of the rain is expected to be light to moderate today through Sunday with some brief heavy downpours of 1 to 2 inches possible Saturday morning through Sunday afternoon.  The storm system could produce more widespread heavy downpours Sunday night into early Monday as the upper low begins to cross Texas.  Soil moisture conditions are not expected to be conducive to flooding initially, but there is a potential for flooding by Sunday night. Areas generally east of I-35 are expected to see the heaviest rainfall and possible flooding.




Low Flood Impacts:

  • Several locations may experience minor flooding with flood waters capable of causing small streams, creeks, canals, and ditches to become swollen and overflow in a few places, but with little to no property damage. Quick ponding of water occurs at underpasses, low-lying spots, and poor drainage areas. Storm drains and retention ponds become near-full and begin to overflow in a few places. Flood waters may prompt brief road closures.
