AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX 445 AM CDT SUN JUN 18 2006 .DISCUSSION... MCS IS MOVING THOUGH MUCH OF THE FORECAST AREA AS WAS WELL FORECAST BY YESTERDAYS MODEL RUNS. IN THE WAKE THIS SYSTEM, THE GFS IS HAVING DIFFICULTY ON WHAT TO DO WITH THE MODIFIED ATMOSPHERE. HAVE OPTED FOR THE MORE STABLE AND DRY ETA MODEL FOR THE NEXT FEW DAYS. UPPER RIDG AXIS WILL TILT EASTWARD TO SUPPRESS THIS MORNINGS MCV FEATURE SOUTHWARD INTO THE GULF. THE GFS STILL HOLDS THIS ENERGY OVER CENTRAL TEXAS, BUT SATELLITE TRENDS FAVOR THE ETA. MODELS HAVE BEEN MIGRATING TOWARD THIS PATTERN FOR THE PAST COUPLE DAYS WITH THE ETA, CANADIAN, AND NOGAPS SHOWING GOOD AGREEMENT THROUGH THE NEXT 4 DAYS OR SO. EXPECT THE REMNANT SHEAR AXIS TO HANG UP OVER THE GULF AND DRIFT WSW ACROSS DEEP SOUTH TX TOWARD MEXICO DURING THE WEEK. EXPECT A SLIGHT CHANCE OF MAINLY DIURNAL RAINS OVER SOUTHERN COUNTIES THROUGH THE MIDDLE OF THE WEEK AND TEMPS TO BE 1-4 DEGREES WARMER THAN THE GFS GUIDANCE MONDAY THRU WEDNESDAY. BY NEXT WEEKEND, MODELS FALL INTO POOR AGREEMENT WITH THE NOGAPS AND CANADIAN CALLING FOR CONTINUED RIDGE STRENGTHENING AND THE ECMWF CALLING FOR UPPER RIDGE WEAKENING FROM THE NORTH AND EAST. WILL SETTLE FOR THE GFS SOLUTION WHICH IS A COMPROMISE, AND OFFER GHOST 10 POPS FOR NEXT WEEKEND. && .PRELIMINARY POINT TEMPS/POPS...
