AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE FORT WORTH TX 1206 AM CDT WED MAY 6 2015 .AVIATION... /06Z TAFS/ CONCERNS...THUNDER POTENTIAL...STRATUS. EVENING THUNDERSTORMS WERE PRIMARILY NORTH OF THE METROPLEX. WITH LIFT FROM AN APPROACHING SHORTWAVE AND A 40-50KT LLJ PROVIDING RICH GULF MOISTURE...THE THUNDER POTENTIAL WILL CONTINUE OVERNIGHT...BUT IT APPEARS THE BULK OF THE ACTIVITY WILL REMAIN ACROSS OKLAHOMA. IN ADDITION...TROPICAL WARM RAIN PROCESSES IN THE AUSTIN AREA WILL SPREAD EASTWARD...PERHAPS DISRUPTING THE INFLOW FOR ANY ACTIVITY NEAR TAF SITES. INTERMITTENT SHOWERS WILL BE THE PRIMARY CONVECTIVE MODE OVERNIGHT. OCCASIONAL MVFR STRATUS HAS ALREADY ACCOMPANIED SHOWERS TONIGHT. DESPITE THE CONVECTIVE ACTIVITY COMPLICATING THE TYPICAL NOCTURNAL STRATUS PROCESS...THE LLJ SHOULD ASSURE MVFR CEILINGS DOMINATE. WEDNESDAY AND WEDNESDAY NIGHT... ON THE BACKSIDE OF THE EXITING SHORTWAVE...EXPECT ONLY SCATTERED DIURNALLY DRIVEN SHOWERS WEDNESDAY AFTERNOON. STRATUS WILL AGAIN BE SLOW TO SCATTER...AND LOW VFR CEILINGS MAY LINGER MUCH OF THE AFTERNOON. AS A RESULT...EXPECT MVFR STRATUS WILL MAKE A QUICKER RETURN WEDNESDAY EVENING...AND IFR CEILINGS MAY BE IN PLACE AS EARLY AS MIDNIGHT. WACO... THE UPSTREAM ACTIVITY MAY PRECLUDE SIGNIFICANT SHOWERS/STORMS FOR WACO OVERNIGHT...BUT OCCASIONAL SHOWERS SHOULD PERSIST. CONFIDENCE IS TOO LOW TO CARRY CATEGORICAL IFR CEILINGS BUT WILL MAINTAIN A TEMPO GROUP FOR AROUND DAYBREAK. 25 && .UPDATE... A FAVORABLE ENVIRONMENT REMAINS IN PLACE FOR WIDESPREAD...AND AT TIMES HEAVY...RAINFALL ACROSS NORTH AND CENTRAL TEXAS. STRONG UPPER LEVEL SHORTWAVE IS PIVOTING ACROSS WEST TEXAS THIS EVENING...PROVIDING GOOD DIFFLUENCE AND FORCING FOR ASCENT ACROSS OUR AREA. THE AIRMASS OVER NORTH TEXAS IS QUITE MOIST NOW...WITH PWATS IN EXCESS OF 1.5". A PRONOUNCED LOW LEVEL CONVERGENCE LINE PERSISTS NEAR A WICHITA FALLS-COMANCHE-LAMPASAS LINE...AND THIS HAS BEEN A FOCUS FOR WIDESPREAD SHOWERS AND ISOLATED THUNDERSTORMS SINCE LATE AFTERNOON. WITH MOIST...HIGH THETA-E AIR FEEDING NORTHWARD PARALLEL TO THIS LINE...WOULD CONTINUE TO EXPECT PERIODS OF HEAVY RAIN IN MANY AREAS ALONG AND WEST OF I-35 OVERNIGHT. SO FAR RAIN RATES HAVE NOT BEEN SUFFICIENT TO WARRANT CONSIDERATION OF FLASH FLOOD WATCHES OR WARNINGS. THIS ENTIRE AREA...HOWEVER...WILL NEED TO BE MONITORED OVERNIGHT IF THIS BROAD AREA COALESCES INTO A LARGER-SCALE CONVECTIVE COMPLEX WITH HEAVIER RAINFALL. HAVE UPDATED THE FORECAST GRIDS TO REFLECT HIGHER POPS ACROSS NEARLY ALL OF THE AREA...AND INCLUDED HEAVY RAINFALL WORDING IN THE WESTERN ZONES. MADE MINOR CHANGES TO TEMPS AS WELL. && .PREV DISCUSSION... /ISSUED 230 PM CDT TUE MAY 5 2015/ A PATTERN OF UNSETTLED WEATHER WILL EXIST OVER THE REGION THROUGH THE WEEKEND AS UPPER SYSTEMS APPROACH FROM THE WEST AND MOVE NORTHEAST THROUGH THE CENTRAL ROCKIES AND CENTRAL PLAINS. THE FIRST SYSTEM IS MOVING OUT OF THE FOUR CORNERS THIS AFTERNOON WITH A VIGOROUS SHORT WAVE PIVOTING INTO WESTERN OKLAHOMA AND NORTH TEXAS THIS EVENING. EARLY AFTERNOON SOUTHERN PLAINS RADAR MOSAIC SHOWS BANDS OF CONVECTION FEEDING INTO THIS SYSTEM AS WELL AS ANOTHER BAND OF LOW LEVEL WARM ADVECTION CONVECTION OVER EAST TEXAS. AS THE AFTERNOON PROGRESSES...WE EXPECT THE WESTERN CONVECTION TO SPREAD FARTHER EAST INTO THE CWA WITH AN INCREASE IN COVERAGE AND INTENSITY. WE HAVE A VERY UNSTABLE ATMOSPHERE IN PLACE AND STRONG UPPER DIFFLUENCE APPROACHING FROM THE WEST THAT WILL TAP INTO HIGH THETA-E AIR RIDING NORTH ON A 30-40 KNOT LOW LEVEL JET...THUS SOME STRONG TO MARGINALLY SEVERE STORMS ARE POSSIBLE THROUGH MID EVENING. ALSO...ECHO TRAINING COULD LEAD TO ISOLATED HEAVY RUNOFF THAT COULD PRODUCE LOCALIZE FLASH FLOODING. AS THE UPPER SYSTEM MOVES FARTHER AWAY FROM THE REGION ON WEDNESDAY...WE EXPECT A LULL IN ORGANIZED CONVECTION WEDNESDAY THROUGH THURSDAY NIGHT. HOWEVER...THERE WILL BE ISOLATED TO SCATTERED ACTIVITY...MAINLY DRIVEN BY NOCTURNAL WARM ADVECTION AT NIGHT AND DAYTIME HEATING EACH AFTERNOON. THE SECOND SYSTEM WILL MOVE DOWN THE WEST COAST WEDNESDAY AND THURSDAY AND INTO THE DESERT SOUTHWEST ON FRIDAY AND OVER THE SOUTHERN/CENTRAL ROCKIES THIS WEEKEND. ONCE AGAIN...THIS SYSTEM WILL SPREAD STRONG UPPER DYNAMICS OVER THE REGION OVER THE WEEKEND WHILE LOW LEVEL MOISTURE CONTINUES TO FEED NORTHWARD ON A STRONG LOW LEVEL JET. ACTUALLY...LOW LEVEL THETA-E...SFC TO 850MB...WILL BE SLIGHTLY HIGHER THAN THOSE EXPECTED TONIGHT. FORECAST SOUNDINGS AND HODOGRAPHS FOR THE WEEKEND PERIOD SHOW A POTENTIAL FOR SOME SEVERE STORMS FORMING AND MOVING OFF A DRYLINE AND INTO THE WESTERN CWA...AND A POTENTIAL FOR VERY HEAVY RAINFALL BOTH SATURDAY AND SUNDAY AS PWATS CLIMB ABOVE THE 2ND STANDARD DEVIATION FOR EARLY MAY. A COLD FRONT WILL ARRIVE ON MONDAY AND SHUNT THE CONVECTION TO THE SOUTHERN CWA MONDAY NIGHT AND MAINLY SOUTH OF THE CWA ON TUESDAY. HIGH TEMPERATURES WILL REMAIN RATHER SEASONAL THROUGH SUNDAY WHILE OVERNIGHT LOWS WILL BE 4 TO 9 DEGREES ABOVE NORMAL. TEMPERATURES WILL TURN A LITTLE COOLER FOR TUESDAY WITH HIGHS GENERALLY 75 TO 80 DEGREES. 75 && .PRELIMINARY POINT TEMPS/POPS... DALLAS-FT.
