...SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS SOUTHEAST TEXAS TODAY
AND INTO THIS EVENING...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF SOUTHEAST TEXAS.

.DAY ONE...TODAY AND TONIGHT...

A SLOW MOVING COLD FRONT LOCATED ACROSS NORTH TEXAS EARLY THIS
MORNING WILL MOVE SOUTH TODAY AND INTO SOUTHEAST TEXAS AROUND
MID-DAY THEN ACROSS THE AREA THIS AFTERNOON AND EVENING. THE
ATMOSPHERE SOUTH OF THIS FRONT IS VERY UNSTABLE DUE TO COLD AIR
PRESENT IN THE MID AND UPPER LEVELS. THE FLOW AT THESE MID AND UPPER
LEVELS IS FROM THE NORTHWEST WHICH WILL RESULT IN THUNDERSTORMS
MOVING SOUTHEAST AND QUICKLY ACROSS THE AREA. AS THE FRONT MOVES
SOUTH TODAY...THUNDERSTORMS ARE EXPECTED TO REPEATEDLY DEVELOP
ALONG THIS BOUNDARY AND THEN MOVE SOUTHEAST ACROSS THE AREA.

A CLUSTER OF THUNDERSTORMS IS ONGOING THIS MORNING JUST NORTH OF
SOUTHEAST TEXAS AND HAS PROMPTED THE ISSUANCE OF A SEVERE
THUNDERSTORM WATCH FOR THE NORTHERN HALF OF SOUTHEAST TEXAS UNTIL
MID-DAY. EXPECT ADDITIONAL WATCHES EXTENDING FURTHER SOUTH LATER TODAY
AND INTO THE EVENING HOURS AS THE FRONT APPROACHES AND MOVES ACROSS
SOUTHEAST TEXAS.

THE PRIMARY SEVERE WEATHER THREATS WILL BE LARGE HAIL AND DAMAGING

And this one will be coming through during the most unstable time of the day. I think their will be some pretty good action out of this one. Time to put my truck under the carport just in case!

check out the latest maps from the SPC! We are literally as close as you can get to a moderate outlook without being moderate:

Image
Tornado risk

Image
Hail risk

Image
Damaging wind risk

...TX TO LOWER MS VALLEY...
A MUCH MORE UNSTABLE AIR MASS IS IN PLACE ACROSS CENTRAL/SRN TX TO S
OF FRONTAL ZONE. ONGOING STRONG/SEVERE THUNDERSTORMS EXPECTED WITH
AFTERNOON HEATING TO INCREASE IN NUMBER AND INTENSITY AS THE STORMS
CONTINUE DEVELOPING S/SEWD THRU MUCH OF TX BY LATER TONIGHT.

GIVEN MLCAPES RISING TO ABOVE 3000 J/KG AND 40-45 KT OF DEEP LAYER
SHEAR...VERY LARGE HAIL WILL BE THE DOMINANT THREAT. THERMODYNAMIC
PARAMETERS GIVEN THE DEEP LAYER SHEAR ALSO SUPPORT SUPERCELL
POTENTIAL. LARGEST HAIL ALONG WITH ISOLATED TORNADOES WOULD BE
ASSOCIATED WITH ANY SUPERCELL THAT DEVELOPS.

SEVERE STORMS WILL PROPAGATE INTO THE VERY UNSTABLE AIR MASS ACROSS
S TX AND LIKELY CONTINUE AFTER DARK.

FURTHER E ALONG GULF COAST...WHILE LAPSE RATES FAVOR A FEW SEVERE
STORMS...INSTABILITY AND SHEAR WILL BE A LITTLE LESS THAN THE
AFOREMENTION AREAS. SEVERE POTENTIAL THUS WOULD BE MORE WIDELY
SCATTERED WITH LARGE HAIL THE DOMINANT THREAT.

I wonder why this thread is getting little to no response? There are currently many warnings up for the state and some potent weather looks to be approaching Houston from the north.

I'm watching it, but working in the yard so mostly lurking. Looks like along I-45 and west is about to get some severe weather.

There now looks to be a warning up for SE Harris County, and the storms to the NW look to be merging and intensifying. It is only a matter of time before it reaches us..

Looking at how impressive the storms to the NW are...I am very surprised that they have let all the warnings expire. Hopefully they will issue new ones soon, because there is no way that they are not severe.

Nothing here yet but plenty of thunder. Very heavy rains to our north and northwest. I hear that parts of I-35 were covered with water between Temple and Waco earlier. Hope those Mothers Day travelers take care!

Serious thunder and it's getting darker here. I was at http://rainbowweather.com/vweather/litng2000.html earlier and it looks like a line is coming right at our house :O

At that site, there's a yellow box around some of the storms but the site legend doesn't explain...

We've got watches up here. Warnings to our NW and E, looks like y'all in Houston are in for a noisey afternoon/evening....

Very wicked skies in League City. The sky has a red and green tint to it.

Shoshana, you're in the NE part of Travis County, right? If I remember correctly you're about 10 miles east of me or thereabouts. I'm near Parmer/Mopac in north Austin.

Gusty winds here now, some thunder ... but nothing substantial yet although that AUS radar is lighting up like a Christmas tree!

Yup - NE Travis Co, about 5-6 miles away from you - near Parmer and Dessau.

Thank goodness for surge protectors and UPSs!

yeah that storm looks to be charging nearly due south right now and will probably be giving the woodlands and Spring a nice blast of severe weather shortly.

We are getting pounded with some serious rain right now in central Montgomery County. No hail but it is the hardest rain I have seen all year by far. I was in my garden out back picking beans watching the clouds and taking pictures of them till the rain and lightning ran me back to the house. I was completely soaked by the time I got to the house but I was able to get dinner just in time!! :lol:

It looks like alot more rain behind this too!
