Jeff Update:

Large squall line extends from east of Waco to College Station to west of Victoria. Meso low east of Waco has bulged the northern end of the line near College Station and this section has recently been tornado warned. South of this bow in the line along I-10 the line has slowed greatly and begun to train in a west-east fashion. Radar indicates rainfall rates up to 2.5 inches in 1 hour along I-10 west of Columbus and flash flooding is likely developing under this core of very heavy rainfall. Southern extent of the line south of I-10 is progressing eastward at 20-30mph. Will likely see another meso low form in the region between Bryan and Columbus this morning and surge the southern end of this line eastward. Damaging winds to 60mph are very likely in the next hour across northern Austin, Brazos, Grimes, northern Waller, and Montgomery Counties Additionally, Corpus and Houston radars both show increasing convection from near Rockport to Matagorda Bay as strong lift is overspreading the warm sector. These cells are rooted near the surface in a strong shearing environment and may have an enhanced tornado threat as they expand/develop northeastward into Jackson, Wharton, Matagorda, and Fort Bend Counties this morning. Strong winds to 60mph and isolated tornadoes along with short term excessive rainfall remain the main threats.

Folks in Colorado/Austin Counties heads up. Heavy rains and strong storm complex for your area

Austin county storm:

[srainhoutx]

Folks in Western and SW areas need to monitor closely. Meso developing in Fayette County showing trends of slow SE movement

[srainhoutx]

Severe Thunderstorm Warning for Austin, Grimes, Harris, Houston, Madison, Montgomery, San Jacinto, Trinity, Waller & Walker Counties

[srainhoutx]

SPC expands Tornado Watch E until 3:00PM into E TX/W LA

[sambucol]

Is Baytown expected to get any of the severe weather and heavy rains?

[srainhoutx]

All the Metro area stands a good chance at seeing some severe weather. Latest radar trends suggests slowing of northern storm complex and concern grows as flood potential may be increasing for areas just W of the Metro Houston area and on E. For everyone in the Metro area, our event is just beginning to materialize...note the inflow of storms off the Gulf heading toward Brazoria County. Meso low is pulling up abundant moisture and that will continue throughout the morning/mid day hours...

Tornado Warning for Grimes, Houston, Madison, Montgomery and Walker Counties

That bow echo is moving straight for my place....

Update from Jeff:

New Severe Thunderstorm Warning for winds to 60mph has been issued until 845am for Waller, N Harris, Montgomery, Walker, San Jacinto, Trinity, Houston, Madison and Grimes Counties. Severe line of thunderstorms capable of damaging straight line winds extends from northern Austin County to Madison County. Radar shows strong westerly winds of 55-60mph along the leading edge of this line moving eastward at 45mph. Damaging winds are likely in the warning area as these storms move quickly across this region. Winds of this magnitude will down trees and power lines and may damage roofs and windows. Extensive amount of trees in this area killed by the ongoing drought may fall in the strong winds. Southward on the line, watching a developing large cell over Colorado County where radar is suggesting low level rotation may be increasing west of Columbus and south of I-10. This cell is in a favorable position to feed off of untapped low level inflow off the Gulf of Mexico with a lack of large severe cells southward over Wharton and Matagorda counties currently. Just in CRP sounding at 600am showed 0-1km shearing values of 400-500 m^2/s^2 so the greatest tornado threat remains with cells developing ahead of the main line and embedded supercells within the main line. Suspect northern edge of the line will bow outward and weaken with time while southern section south of I-10 intensifies as it moves eastward into Jackson, Wharton, and Colorado counties.

Oh my gosh. We are leaving for downtown at 10 am. That stuff will get here right as we leave. Lovely. Stay safe out there you all. This could be an interesting day.

[singlemom]

So....am I correct in saying that the bulk of the storms are heading North towards Waller and Grimes (Brenham, etc.)? Or, has it slowed down and is still heading East? I'm over here in Humble with 700 kiddos....of course I'll be prepared but just wondering.....
