AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 341 PM CDT SUN JUL 19 2009 .DISCUSSION... SCATTERED SHOWERS AND THUNDERSTORMS HAVE DEVELOPED ACROSS THE SOUTHERN HALF OF THE AREA THIS AFTERNOON AS THE SEABREEZE HAS PUSHED WELL INLAND. ADDITIONALLY...AN AREA OF STRONG TO SEVERE THUNDERSTORMS HAVE DEVELOPED ACROSS PORTIONS OF NORTH CENTRAL TEXAS. SPC HAS ISSUED A SEVERE THUNDERSTORM WATCH THAT INCLUDES MOST OF THE NORTHERN HALF OF OUR CWA THROUGH 9 PM TONIGHT. HAVE INCREASED POPS FOR THIS EVENING ACROSS OUR NORTHEASTERN COUNTIES IN ANTICIPATION OF THESE STORMS MOVING SOUTH SOUTHEASTWARD INTO THE REGION. THE GFS HAS SUGGESTED A SIMILAR SCENARIO FOR THE PAST FEW RUNS WITH AN MCS DEVELOPING NEAR THE DFW METROPLEX AND PROPAGATION SOUTHEAST INTO EAST TEXAS AND SW LOUISIANA OVERNIGHT. THIS ACTIVE WEATHER PATTERN LOOKS TO CONTINUE AT LEAST THROUGH MID WEEK AS THE UPPER LEVEL RIDGE REMAINS OUT WEST...ALLOWING DISTURBANCES TO APPROACH THE AREA FROM THE NORTHWEST. AS HAS BEEN THE CASE FOR THE PAST SEVERAL DAYS MESOSCALE EVENTS WILL BE THE PRIMARY FORCE DRIVING DEVELOPMENT OVER THE NEXT FEW DAYS...MAKING EXACT TIMING OF RAINFALL EVENTS DIFFICULT. HAVE ELECTED TO KEEP POPS FOR THE NEXT FEW DAYS FAIRLY GENERIC...INCREASING FIRST ALONG THE COAST TO ACCOUNT FOR SEABREEZE DEVELOPMENT AND THEN INCREASING POPS INLAND DURING THE AFTERNOON AND EARLY EVENING HOURS. BEGINNING ON THURSDAY THE UPPER LEVEL RIDGE IS EXPECTED TO INTENSIFY AND MOVE SLIGHTLY EASTWARD. THIS WILL SHIFT THE BEST PRECIPITATION CHANCES EASTWARD OUT OF THE AREA AND ALLOW AFTERNOON HIGH TEMPERATURES TO SLOWLY INCREASE HEADING INTO NEXT WEEKEND...WITH OUR NORTHERN COUNTIES NEARING TRIPLE DIGITS BY SATURDAY. 38 && .PRELIMINARY POINT TEMPS/POPS...
