Very Impressive! (From my point of view in NW Harris County)

Srain- I'm startign to wonder if upstream storms will make it, numerous outflow boundariesseem to be choking out everything, what do you think?

I knew it would be just a matter of time..

This is crazy- all storms through the out state have been moving mostly southeastward. Storms near Brenham are moving northeastward.

I don't think they will make it. I think the storms around Dallas are about to get hit with one more boundary but then i think the storms are just going to fall apart until tomorrow.

Been a mighty long journey from the Panhandle this morning. With that said, the cold pool that developed certainly gave it a boost into our Northern Regions.

Storms near NW Harris County appear to be weakening. With the loss of heating, they won't likely survive to reach central Harris County.

Looks like Austin is catching round 2....

FLASH FLOOD WARNING

658 PM CDT MON MAY 17 2010

THE NATIONAL WEATHER SERVICE IN AUSTIN SAN ANTONIO HAS ISSUED A

* FLASH FLOOD WARNING FOR...
HAYS COUNTY...
WESTERN TRAVIS COUNTY...

* UNTIL 900 PM CDT.

* AT 654 PM CDT...NATIONAL WEATHER SERVICE METEOROLOGISTS HAVE
DETERMINED THAT RAINFALL ESTIMATES FROM DOPPLER RADAR INDICATE
FLASH FLOODING FROM A THUNDERSTORM OVER THE WARNED AREA.

* LOCATIONS IN THE WARNING INCLUDE BUT ARE NOT LIMITED TO WIMBERLEY
AND DRIPPING SPRINGS.

MANY OF THE THUNDERSTORMS PRODUCING HEAVY RAINFALL ARE BEGINNING TO
WEAKEN. HOWEVER...ADDITIONAL RAINFALL OF 2 TO 3 INCHES IS POSSIBLE
THROUGH THIS EVENING. ALSO...RUNOFF FROM STORMS ACROSS THE HILL
COUNTRY CAN BE EXPECTED.

I notice a nice cluster of thunderstorms north of here. I wonder if they will effect us. If so, could they be a Mesoscale Convention System (MCS)? I notice a lot of outflow boundries.

impressive storm development in milam county. the southeastward-moving OFB won the boundary battle and the cells are blooming right on its heels. on a broader scale, there does appear to possibly be some conglomeration going on as one or two huge bowing segments are forming.

We heard a few claps of thunder but nothing else....I guess the storms are over now that the sun is going down? I hope everyone stayed safe! Thanks for all you do!

Radar indicating 1.25'' hail with the storm in southwest Harris and northeast Ft. Bend county. Would not suprise me to see this storm go severe if it continues to develop. Watch out around the Westbury, Stafford, Meadows, Sugar Land, and Missouri City areas. The storm looks to be relatively stationary at this time so some localized flooding is possible as well.

AREAS AFFECTED...CENTRAL AND SERN TX

CONCERNING...SEVERE THUNDERSTORM WATCH 182...

VALID 180046Z - 180215Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 182
CONTINUES.

WIDESPREAD STRONG/LOCALLY SEVERE THUNDERSTORMS CONTINUE MOVING
GENERALLY SEWD ACROSS CENTRAL AND SERN TX...WHICH WILL LIKELY
REQUIRE NEW WW ISSUANCE DOWNSTREAM.

LATEST RADAR IMAGERY SHOWS THUNDERSTORMS INCREASING IN COVERAGE
ACROSS WW 182...AS NUMEROUS OUTFLOW BOUNDARIES WHICH HAVE CONVERGED
OVER THE PAST HOUR ENHANCE LOW-LEVEL UVV.

SHEAR REMAINS ONLY MARGINALLY SUPPORTIVE OF STORM ORGANIZATION.
HOWEVER...VERY UNSTABLE AIRMASS -- RESULTING IN WIDESPREAD STORMS --
SUGGESTS POTENTIAL THAT INCREASING MESOSCALE ORGANIZATION WILL BE
POSSIBLE WITH STORMS ACCELERATING SEWD AT THE LEADING EDGE OF AN
EXPANDING COLD POOL. WHILE THIS SCENARIO HAS YET TO FULLY
MATERIALIZE...TWO AREAS OF WEAK MESOSCALE CYCLONIC CIRCULATION ARE
EVIDENT -- ONE INVOF NRN PARTS OF ROBERTSON AND LEON COUNTIES AND
THE OTHER MOVING INTO GILLESPIE COUNTY. GIVEN DEGREE OF DOWNSTREAM
INSTABILITY...IT APPEARS THAT POTENTIAL FOR FURTHER ORGANIZATION ON
THE MESOSCALE IS POSSIBLE...AND THUS ATTM A NEW WW COVERING PARTS OF
SRN AND SERN TX APPEARS LIKELY.

Hello everyone, it's storm season again and hello.

Normally I would bet my next paycheck these storms would break up before getting to Pearland.
They don't seem to be falling apart as quickly as normal.
