349 AM CDT THU OCT 2 2014

.DISCUSSION...A STRONG UPPER DISTURBANCE IS CURRENTLY MOVING
ACROSS THE HIGH PLAINS WITH THUNDERSTORMS STRETCHING FROM THE
MIDWEST TO NORTH TX ALONG AND AHEAD OF A COLD FRONT. LOCALLY UPPER
DIVERGENCE IS BEGINNING TO OCCUR AS THE SHORT WAVE DRAWS SLOWLY
CLOSER. THIS HAS LEAD TO A FEW SHOWERS ACROSS THE REGION, HOWEVER
MOST CONVECTION IS NOT EXPECTED UNTIL AFTER SUNRISE WHEN DIURNAL HEATING
BEGINS. TONIGHT INTO FRIDAY MORNING THE SHORT WAVE WILL MOVE
ACROSS THE REGION SWINGING A PRE-FRONTAL TROUGH THROUGH THE
AREA. THUNDERSTORMS WILL MOVE INTO THE EAST TX LAKES REGION
BEFORE MIDNIGHT AND LIKELY MOVE INTO THE GULF COASTAL WATERS BEFORE
SUNRISE. THE BEST DYNAMICS WILL REMAIN REMOVED FROM THE AREA,
HOWEVER ONE OR TWO ISOLATED STRONG TO POSSIBLY EVEN SEVERE STORMS
MAY BE POSSIBLE MAINLY ACROSS THE NORTHERN SECTIONS OF THE CWA
WITH GUSTY STRAIGHT LINE WINDS BEING THE MAIN THREAT. RAIN CHANCES
WILL DECREASE THROUGH FRIDAY MORNING WITH THE FRONT MOVING TO THE
COAST BY MID MORNING TO MID DAY. MUCH COOLER AND DRIER WEATHER IS
IN STORE FOR THE WEEKEND BEHIND THE FRONT WITH TEMPERATURES
FALLING TO WITHIN SEVERAL DEGREES OF RECORD LOWS BY SUNDAY
MORNING. THE RIDGE RESPONSIBLE FOR THE COOL AIR WILL SLIDE ACROSS
THE NORTHERN GULF COAST SUNDAY BEGINNING A RETURN FLOW BY SUNDAY
NIGHT INTO MONDAY. THIS WILL ALLOW WARMING AND MOISTENING WITH A
RETURN OF A FEW SHOWERS POSSIBLE BY MONDAY MORNING.
