A STRONG UPPER LEVEL STORM SYSTEM AND A SURFACE COLD FRONT WILL CROSS TEXAS THIS AFTERNOON AND WILL EXIT THE STATE EARLY SUNDAY MORNING. SCATTERED SHOWERS AND THUNDERSTORMS WILL DEVELOP ACROSS SOUTHEAST TEXAS AS DAYTIME HEATING HELPS TO DESTABILIZE THE ATMOSPHERE ACROSS THE AREA AND UPPER LEVEL LOW PRESSURE APPROACHES FROM THE WEST.

LARGE HAIL WILL ALSO BE POSSIBLE AS A POCKET OF COLDER AIR MOVES ACROSS THE REGION AROUND SUNSET. THERE IS ALSO A RISK FOR TORNADOES LATER THIS AFTERNOON AS LOW PRESSURE ADVANCES TOWARD SOUTHEAST TEXAS. AS THE LOW PRESSURE AREA APPROACHES...LOW LEVEL WIND SHEAR...OR WINDS TURNING WITH HEIGHT...

LOCATIONS FURTHER NORTH OF THE INTERSTATE...ROUGHLY ALONG AND NORTH OF A LINE FROM BRENHAM TO LAKE LIVINGSTON...HAVE A SLIGHTLY BETTER CHANCE OF SEVERE WEATHER WITH THIS STORM SYSTEM. PERSONS NORTH AND SOUTH OF INTERSTATE 10 SHOULD REMAIN ALERT FOR POSSIBLE SEVERE THUNDERSTORM OR TORNADO WATCHES LATER TODAY. THE SEVERE WEATHER THREAT IS EXPECTED TO COME TO AN END LATER THIS EVENING AS THE STORM SYSTEM MOVES OFF TO THE EAST. THIS IS A POTENTIALLY VERY DANGEROUS WEATHER SITUATION.
