.
EVENT...MOD/HVY RAIN ASSOCIATED WITH CONVECTION OVER E TX/SW AR
.
SATELLITE ANALYSIS AND TRENDS...LATEST GOES WV IMAGERY SHOWS A POTENT
MID/UL LOW OVER SW TX THAT CONTINUES TO SLOWLY MOVE EWD ATTM. A FEW WEAKER
MID/UL IMPULESE, ONE OVER E TX AND A SECOND OVER SW MO ARE MOVING NEWD
AHEAD OF THE MID/UL LOW. MAIN CONCERN FOR HVY RAIN THE NEXT FEW HRS IS
WITH THE IMPULSE OVER ERN TX THAT IS HELPING TO SUPPORT DEEP CONVECTION
WITHIN AN AREA OF HIGHER MOISTURE SITUATED ACROSS MUCH OF THE REGION. AT
THE SFC, A SFC LOW OVER NE TX CONTINUES TO TRACK NEWD ALONG A SFC BOUNDARY
TOWARD NW LA/SW AR. IR IMAGERY SHOWS THAT THE MOST ACTIVE CONVECTION IS
OVER ERN TX AND IS SITUATED ALONG A SFC FRONT AND IN THE VICINITY OF THIS
SFC LOW. CLOUD TOPS CONTINUE TO COOL/EXPAND IN IR IMAGERY WITH SOME OF THE
COLDER CLOUD TOPS STARTING TO SPREAD NWD INTO SERN OK/SWRN AR. BASED ON
SFC OBS, RAIN RATES ARE AVERAGING 1-2"/HR WITH THE CONVECTION RESULTING
IN A QUICK 1-2" OF RAIN IN MOST AREAS. A FEW ISOLATED SPOTS HAVE PICKED
UP 4-6" CLOSE TO KAUS WHERE CONVECTION HAD TRAINED THE LONGEST. WHILE
RAIN FALL AMTS MAY NOT BE QUITE THAT HEAVY, ADDITIONAL RAIN FALL AMTS
OF 1-3" MAY BE COMMON WITH THE HEAVIEST AMOUNTS BEING FOCUSED OVER NE
TX/SE OK/SW AR/NW LA THE NEXT FEW HRS ALONG THE SFC LOW TRACK.
.
SHORT TERM OUTLOOK VALID 1430Z-1830Z...MEDIUM CONFIDENCE FACTOR IN SHORT
TERM OUTLOOK...THREAT FOR EXCESSIVELY HVY RAIN MAY BE DWINDLING A BIT AS
CONVECTION MOVES EWD A BIT FASTER ACROSS TX. HOWEVER, STILL THINK THAT
THE THREAT FOR MOD/HVY RAIN EXISTS, ESPECIALLY ACROSS NE TX/SE OK/SW AR/NW
LA CLOSER TO SFC LOW TRACK/UL IMPULSE TRACK THE NEXT FEW HRS. MEANWHILE,
AREAS FARTHER S TOWARD THE TX COAST MAY EXPERIENCE A 30-45 MINUTE PERIOD
OF HVY RAIN AS THE CONVECTION MOVES THROUGH RESULTING IN A QUICK 1-1.5"
OF RAIN IN MOST AREAS.

Was getting pounded with chubby rain and serious wind about 20 min. ago here in Fulshear...

But it appears things have eased somewhat.

Update from Jeff:

Severe Thunderstorm Warning for Wharton and Fort Bend counties until 1030am. Radar indicates a line of severe thunderstorms from near East Bernard to El Campo moving ENE at 35mph. Winds to 60mph are possible with this line as it moves nearly along/just north of US 59. Locations in the path of this line include: Wharton, El Campo, Richmond, Rosenberg, Pecan Grove. Storms today have had a history of producing damaging winds (see photos below from the College Station area). Additionally the Brenham airport recorded a 70mph wind gust earlier this morning. Urban and Stream Streams Flood Advisory has been issued for Harris, Fort Bend, Austin, Waller and Wharton counties until 1145am. Radar is showing hourly rainfall rates of 2-3 inches over Austin and Wharton Counties and this excessive rainfall will be spreading into Fort Bend and Harris Counties shortly. Rapid flooding of streets and low lying areas is likely. Storm totals may be enough to push small streams out of their banks.
