AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX 259 PM CDT SUN APR 12 2015 .DISCUSSION... SCATTERED SHOWERS HAVE BEGUN TO DEVELOP ACROSS PARTS OF SOUTHEAST TEXAS THIS AFTERNOON AS BREAKS IN THE CLOUDS HAVE BROUGHT SOME OF OUR TEMPERATURES (2 PM READINGS) CLOSE TO 80 DEGREES. EXPECT ACTIVITY TO CONTINUE TO DEVELOP DURING THE REST OF THE AFTERNOON WITH SOME THUNDER AND BRIEF LOCALLY HEAVY RAINFALL POSSIBLE TOO. MUCH OF THE AREA SHOULD SEE A BREAK THIS EVENING...THEN A FAST EASTWARD MOVING STORM COMPLEX (SHOWERS/THUNDERSTORMS WITH LOCALLY HEAVY RAINFALL AND POSSIBLY SOME STRONG GUSTY WINDS TOO) IS ANTICIPATED TO MOVE INTO MUCH OF OUR CENTRAL AND SOUTHERN AREAS FROM THE WEST DURING THE OVERNIGHT THROUGH EARLY MORNING HOURS. IF WE CAN HANDLE WHAT RAIN FALLS OVER THE NEXT SEVERAL HOURS...CURRENT THINKING IS THAT WE SHOULD BE ABLE TO HANDLE THE OVERNIGHT SYSTEM AND ITS HEAVY RAINFALL TOO DUE TO ITS EXPECTED FAST EASTWARD MOVEMENT. THE GREATEST RISK FOR SEVERE STORM DEVELOPMENT WITH THESE STORMS WILL BE OFF TO OUR WEST AND SOUTHWEST WHERE SPC HAS PARTS OF THE STATE UNDER THEIR DAY 1 SLIGHT RISK. BACK OVER HERE FOR THE REST OF TODAY AND ON THROUGH MONDAY...RAINFALL TOTALS ARE EXPECTED TO AVERAGE AROUND 1 INCH WITH ISOLATED 2 TO 4 INCHES POSSIBLE WITH THE STRONGER ACTIVITY. WILL CARRY LOWER RAIN CHANCES AS WE HEAD INTO THE AFTERNOON HOURS TOMORROW DUE TO EXPECTED TEMPORARY STABILIZATION...BUT THE SLOW MOVING WEST TEXAS MID/UPPER LEVEL LOW COULD SUPPORT MORE STORM DEVELOPMENT AS WE HEAD ON INTO MONDAY NIGHT AND TUESDAY. OUR AREA IS EXPECTED TO REMAIN IN A SOUTHWEST FLOW ALOFT FOR MUCH OF NEXT WEEK...AND THIS SHOULD PROVIDE US WITH ADDITIONAL PERIODS OF SHOWERS AND THUNDERSTORMS. HAVE NOW EXTENDED RAIN CHANCES ON INTO NEXT SATURDAY AS THE PREVIOUSLY ADVERTISED COLD FRONT LOOKS DELAYED ONCE AGAIN. 42 && .MARINE... SHOWERS AND THUNDERSTORMS WILL CONTINUE OVER THE COASTAL WATERS THIS AFTERNOON AND EVENING. ANOTHER ROUND OF STORMS ARE POSSIBLE LATE TONIGHT AND INTO MONDAY MORNING AS AN UPPER LEVEL DISTURBANCE APPROACHES FROM THE WEST... WITH LOCALLY ELEVATED WINDS AND SEAS POSSIBLE NEAR ANY STORM. MESSY SOUTHWEST FLOW ALOFT WILL CONTINUE THROUGH THE REMAINDER OF THE WEEK WITH AN EFFECTIVE SHORTWAVE PARADE KEEPING THE POSSIBILITY OF THUNDERSTORMS OVER THE COASTAL WATERS INTO NEXT WEEKEND. GUIDANCE STILL WAFFLING A BIT REGARDING THE COLD FRONT ON TUESDAY... WITH SOME INDICATION THAT IT MAY REACH PARTS OF THE MIDDLE TO UPPER TEXAS COAST SOMETIME TUESDAY MORNING. ANY WIND SHIFT ASSOCIATED WITH THIS WOULD BE BRIEF... WITH LIGHT TO OCCASIONALLY MODERATE ONSHORE FLOW PERSISTING THROUGH THE WEEK. ANOTHER COLD FRONT REMAINS POSSIBLE FOR THE COASTAL WATERS NEXT WEEKEND. HUFFMAN && .AVIATION... SCATTERED CONVECTION CONTINUES TO DEVELOP ACROSS AREA TAF SITES THIS AFTERNOON. MAIN CONCERN FOR THE TERMINALS WOULD BE LIGHTNING AND BRIEF HEAVY RAIN... WITH A FEW ISOLATED STRIKES HAVING ALREADY BEEN OBSERVED THIS AFTERNOON. UPDATED TAFS TO REFLECT TEMPO MENTION OF TSRA THROUGH 23Z. ADDITIONALLY... KHGX VAD WIND PROFILER IS SHOWING 15 TO 20 KNOT WINDS JUST OFF THE SURFACE THIS AFTERNOON AND A FEW ISOLATED... ELEVATED GUSTS NEAR TSRA MAY BE POSSIBLE AS WELL. HUFFMAN && .PRELIMINARY POINT TEMPS/POPS...
