AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 355 PM CDT SUN APR 25 2004 .DISCUSSION...CONVECTIONS HAS TRAILED OFF FOR MOST OF SOUTH CENTRAL TEXAS THIS AFTERNOON. HOWEVER...CONVECTION CONTINUES ALONG THE RIO GRANDE...WITH MORE ASSOCIATED WITH THE UPPER LOW OVER NORTHEASTERN NEW MEXICO AND THE TEXAS PANHANDLE. WILL ALLOW THE FLASH FLOOD WATCH TO EXPIRE AT 4 PM. THE MAIN FORECAST ISSUES ARE POPS/FOG TONIGHT...TEMPS MON-WED...AND POPS THU-SUN. THE VARIOUS FORECAST MODELS ARE IN GOOD AGREEMENT THROUGH 72 HRS... THEN DIFFER ON HOW TO HANDLE AN UPPER LOW CUTTING OFF OVER THE SOUTHWEST U.S. LATE IN THE WEEK. PREFER THE GFS/NOGAPS SOLUTION FOR A SLOWER DEEPER LOW...FOR WHICH THESE MODELS ARE ALREADY ADJUSTING TO THE NORMAL MODEL BIAS OF TOO FAST/SHALLOW. THAT SAID...BELIEVE COLD AIR ADVECTION...LINGERING CLOUDS/POPS...AND EVAPORATION OF THE PAST FEW DAYS RAIN WILL HOLD TEMPS SIGNIFICANTLY UNDER MAV GUIDANCE. TOMORROW. OTHERWISE...FOLLOWED ENSEMBLE GFS MOS FOR MOST PERIODS. AREAL COVERAGE OF SHOWERS AND THUNDERSTORMS WILL BE SMALL TONIGHT... UNLESS GFS SOLUTION OF BLOWING UP THE PANHANDLE CONVECTION INTO A SOUTHEASTWARD MOVING MCS. ALTHOUGH THESE ARE COMMON DURING THE LATE SPRING/EARLY FALL...IT SEEMS OVERDONE BY THE GFS. OTHERWISE...EXPECT PATCHY FOG LATE TONIGHT/EARLY MON BEFORE MODERATE WINDS AND DRIER AIR MIX IN BEHIND THE COLD FRONT. THE REST OF MID-WEEK WILL BE DRY WITH PERIODS OF MID/UPPER LEVEL PARTLY CLOUDY COVERAGE AND NEAR NORMAL TEMPS. AN IMPULSE SEEN OFF BAJA ON THE WV IMAGERY SEEMS WELL CAPTURED BY THE MODELS. HOWEVER... A CLOSED GULF...TRANSITION OVER THE MEXICAN MOUNTAINS...AND OVERALL DRY VERTICAL PROFILE ALL POINT TO NO POPS. THE CUTOFF LOW WILL BEGIN TO INDUCE RETURN GULF FLOW ON THU...SO STARTED LOW POPS THERE AND CARRIED THEM THROUGH SUN. THE BEST CHANCE OF PRECIP WILL PROBABLY BE FRI NIGHT/SAT...BUT TOO FAR OUT IN RANGE TO DEVIATE FROM MODEL GUIDANCE. && .PRELIMINARY POINT TEMPS/POPS...
