May Weather Discussion.

[Ptarmigan]

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.

[rnmm]

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!

[svrwx0503]

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.

[Rip76]

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.

Kayci I am sorry about your tree...my aunt lives in Texas City and never led on that the weather got that bad over there. I live in Santa Fe and I mean we had some pretty good lightning and heavy rain and winds but nothing to warrant downed trees.

As far as us being out of danger for tonight, I have been looking at the radar and I thought the storms were starting to pucker out, now I am not so sure....

[wxman57]

First area of storms did break apart. However, an outflow boundary from the storm in SE Harris County moved along the south 610 loop and developed a heavy storm over SW Houston. Just got 1.75" of rain in Westbury in about 20 min. That storm moved off to the west now.

[spadilly]

I'm sitting outside in spring valley watching it. This has to be one of the best displays of lightning I have ever seen. It's unbelieveable!

[gocuse22]

seems like sugar land is missing that storm.

staying just to the north of my location but an awesome display of lightning!!!!!!

[weatherguy425]

Watch central Texas! Along with the west the Harris County ceel to fire new storms along outflow boundaries.

[svrwx0503]

Had three rounds of dime to quarter sized hail here in western Harris county. The cloud to ground lightning was insane too.
