THIS AFTERNOON A RAIN-COOLED OUTFLOW BOUNDARY THAT ORIGINATED FROM THE NORTH TEXAS MCS...WAS MOVING SOUTHWARD ACROSS THE HILL COUNTRY AND OUR NORTHEAST COUNTIES. THIS BOUNDARY WAS TRIGGERING SCATTERED SHOWERS AND THUNDERSTORMS. OTHER ISOLATED SHOWERS AND THUNDERSTORMS WERE FORMING OVER THE COASTAL PLAINS IN THE VICINITY OF THE SEA BREEZE. WE EXPECTED THIS CONVECTION TO CONTINUE INTO THE EVENING HOURS...BEING SUSTAINED BY OUTFLOW BOUNDARY MERGERS. THE STRONGER STORMS ARE CAPABLE OF PRODUCING LOCALLY HEAVY RAINFALL AND WIND GUSTS OF 30 TO 40 MPH. THE CONVECTION WILL WANE OVERNIGHT WITH THE LOSS OF DAYTIME HEATING. A COLD FRONT THAT IS CURRENTLY MOVING SOUTHWARD ACROSS THE TEXAS PANHANDLE AND NORTHWEST OKLAHOMA WILL BE ENTERING THE HILL COUNTRY FRIDAY MORNING. THE GFS/ECMWF/NAM ARE IN GOOD AGREEMENT WITH THE TIMING OF THE FRONTAL BOUNDARY AND ASSOCIATED PCPN CHANCES. THUS THIS FCST WILL CLOSELY FOLLOW THE GFS MOS OUTPUT. CONVERGENCE ALONG THE FRONTAL BOUNDARY AND WEAK UPPER LEVEL SUPPORT WILL RESULT IN SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS ON FRIDAY. AFTERNOON TEMPS WILL BE COOLER IN MOST LOCATIONS DUE TO THE CLOUD COVER ASSOCIATED WITH THE EXPECTED PCPN. HIGHS OF FRIDAY WILL RANGE FROM THE MID 80S ACROSS THE HILL COUNTRY TO MID 90S ACROSS OUR SOUTHWEST COUNTIES. THE AREA OF SHOWERS AND THUNDERSTORMS WILL MOVE TO THE SOUTH AND SOUTHWEST FRIDAY EVENING INTO EARLY SATURDAY MORNING. A DRY AND STABLE AIRMASS WILL OVERSPREAD SOUTH CENTRAL TEXAS ON SATURDAY. THE LOWER DEWPOINTS ASSOCIATED WITH THE AIRMASS WILL RESULT IN TEMPS SATURDAY MORNING RANGING FROM THE LOWER 60S ACROSS THE HILL COUNTRY TO LOWER 70S ACROSS OUR SOUTHEAST COUNTIES. THE DRY AIRMASS WILL REMAIN ACROSS SOUTH CENTRAL TEXAS ON SATURDAY AND THIS WILL ALLOW TEMPS TO WARM BACK INTO THE 90S IN THE AFTERNOON FOR A MAJORITY OF THE REGION. ANOTHER PLEASANT NIGHT WILL FOLLOW WITH LOWS SUNDAY MORNING IN THE MID 60S TO NEAR 70. THE UPPER LEVEL RIDGE WILL SHIFT EASTWARD EARLY NEXT WEEK ALLOWING THE LOW LEVEL GULF MOISTURE TO RETURN TO SOUTH CENTRAL TEXAS. RAIN CHANCES ALSO RETURN EARLY NEXT WEEK AS WEAK UPPER LEVEL DISTURBANCES ROTATE CLOCKWISE AROUND THE WESTERN PERIPHERY OF THE UPPER LEVEL RIDGE AND TRAVERSE SOUTH CENTRAL TEXAS. && .PRELIMINARY POINT TEMPS/POPS...
