We may have to wait for the next upper disturbance to 'make the curve' before the front really begins to move..

Didn't hear of that upper disturbance. What effect could it have?

That being said, wind stream lines over Texas show the wind shift has made it to the i-35 corridor (maybe a hint of a meso low south of Dallas.) As that upper system swings around the main low, the front 'should' get a kick and start moving more quickly....

Just another in a series of smaller vortexes rotating around the main upper low...

Boy, that's a question even the NWS can't answer.

As everything moves east overnight, expect to see what you see out west over s.e. Texas. That is not to say that those storms will march east, but rather that new cells will form as the area moves eastward. Earlier statements hold, in that I10, North, with areas north of Montgomery County with the higher chances for greater concentrations of severe weather.

Never the less, those in the Tornado watch should pay close attention. Everyone else in S.E. Texas should watch for changes in the forecast for their county as the night progresses.

This is going to be, and has already been, a huge weather event for many in Texas, as well as other States. Let's hope that our part of Texas just gets in on some heavy rain without the tornadic activity that some folks will surely see.

EWX radar is showing the front on the move now, passing the I-35 corridor. 4-7am-ish seem reasonable for frontal passage here.

Although the storms are still firing behind the front, the strongest storms are located along and ahead of the front.

NWS STORM PREDICTION CENTER NORMAN OK
0120 AM CDT SAT APR 24 2010

AREAS AFFECTED...NERN TX THROUGH NRN LA AND SWRN AR

CONCERNING...TORNADO WATCH 82...

VALID 240620Z - 240645Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 82 CONTINUES.

TORNADO WATCH 82 WILL BE REPLACED SOON BY ANOTHER TORNADO WATCH THAT
WILL EXTEND THROUGH NERN TX...SWRN AR AND NRN LA.


LINE OF STORMS OVER NERN TX IS EXPECTED TO CONTINUE EWD THROUGH
MODERATELY UNSTABLE ATMOSPHERE. RECENT OBJECTIVE ANALYSIS INDICATES
THE ATMOSPHERE REMAINS CAPPED FROM NERN TX TROUGH NRN LA.
HOWEVER...RADAR DATA INDICATE THE LINE IS ORGANIZED WITH ROTATING
COMMA HEAD AND IS EMBEDDED WITHIN STRONG VERTICAL SHEAR. STRONG
CONVERGENCE ALONG THE CONVECTIVE OUTFLOW BOUNDARY WILL LIKELY
MAINTAIN THIS ACTIVITY AS IT DEVELOPS EAST. POTENTIAL WILL EXIST FOR
THE CAP TO WEAKEN WITHIN THE DEVELOPING WARM ADVECTION REGIME AND AS
HEIGHTS FALL DOWNSTREAM FROM ADVANCING UPPER TROUGH. THIS COULD
SUPPORT MORE DISCRETE STORMS MAY DEVELOPING EAST OF THE LINE LATER
THIS MORNING.

All along the SPC has said that the northern sections of SE TX were under the greatest risk. So far that has proven to be true. What we need to watch for here in Houston are 'home grown' storms or a squall line taking shape between San Antonio and here in the next hour or two.
