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

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!

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!! 
It looks like alot more rain behind this too!
