NORTH TEXAS UP THROUGH CENTRAL OKLAHOMA...THEN BEGIN TO LIFT NORTH
AS A WARM FRONT THIS EVENING. NEAR AND NORTH OF THIS FRONT...
SCATTERED SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE. DUE TO
LIMITED INSTABILITY AND WIND SHEAR...ORGANIZED SEVERE STORMS ARE
UNLIKELY.

AS DEEP TROPICAL MOISTURE PROGRESSES NORTHWARD OVER TEXAS...SHOWERS
AND A FEW STORMS WILL MOVE INTO WESTERN NORTH TEXAS AND SOUTHERN
OKLAHOMA. INSTABILITY WILL BE MINIMAL...BUT WIND SHEAR WILL INCREASE
OVERNIGHT AS THE REMNANT CIRCULATION OF TROPICAL STORM HERMINE MOVES
CLOSER. THIS INCREASED SHEAR MAY ALLOW ISOLATED DAMAGING WIND GUSTS
WITH STORMS OVER WESTERN NORTH TEXAS. HOWEVER...THE GREATER RISK
OVERNIGHT APPEARS TO BE VERY HEAVY RAIN.

RAIN CHANCES WILL INCREASE OVER THE REGION WEDNESDAY THROUGH EARLY
THURSDAY AS THE REMNANTS OF TROPICAL STORM HERMINE APPROACH.
ALTHOUGH INSTABILITY WILL BE LACKING...STRONG DIRECTIONAL WIND SHEAR
ASSOCIATED WITH THE REMNANT CIRCULATION OF HERMINE MAY ALLOW SOME
STORMS TO PRODUCE WIND DAMAGE WEDNESDAY AND WEDNESDAY NIGHT.

AS ANOTHER FRONTAL BOUNDARY APPROACHES THE REGION THIS WEEKEND AND
LINGERS INTO EARLY NEXT WEEK...ISOLATED OR SCATTERED STORMS WILL BE
POSSIBLE.

OTHER HAZARDOUS WEATHER...
HEAVY RAIN WILL CREATE THE POTENTIAL FOR FLASH FLOODING AND FLOODING
OF MAIN-STEM RIVERS WEDNESDAY AND THURSDAY. A FLASH FLOOD WATCH IS
IN EFFECT FOR MUCH OF THE REGION WEDNESDAY MORNING THROUGH THURSDAY
MORNING. PERSONS LIVING IN OR WITH INTERESTS IN AREAS PRONE TO
FLOODING SHOULD TAKE STEPS TO MINIMIZE IMPACTS.
