Area forecast discussion, Apr 21, 3:01 PM CDT, 5 hours 26 minutes before
TEXAS/OKLAHOMA PANHANDLES AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AMARILLO TX 245 PM CDT MON APR 21 1997 COLD FRONT AT THE SURFACE WAS PUSHING SOUTH ACROSS THE NORTHERN TEXAS PANHANDLE AS OF 200 PM. MID LEVEL SHORT WAVE NOW PUSHING INTO NORTHWEST ARIZONA. ABUNDANT LOW LEVEL MOISTURE IS STILL SOUTH OF THE PANHANDLES AND IS EXPECTED TO STAY THERE UNTIL AFTER THE COLD FRONT PASSES THE AREA...SO WE WILL NOT MENTION ANY SEVERE THUNDERSTORMS IN THE ZONES TONIGHT. WE LIKE THE SURFACE PATTERN OF THE ETA...BUT WE LIKE THE UPPER LEVEL PATTERN OF THE AVN/NGM THROUGH THE NEXT 48 HOURS. ONE THING THAT WE ARE PUZZLED ABOUT IS THE BULLSEYE WE ARE GETTING OVER PANHANDLES FROM THE MODEL QPF OUT PUTS. WE WILL STILL GO WITH POPS AROUND 50 PERCENT ACROSS THE AREA...BUT THINK THAT THE HEAVIEST RAIN WILL STAY TO THE SOUTH. WE WILL LINGER A LITTLE RAIN INTO THE MORNING HOURS. WE WILL KEEP CLOUDS IN FOR MOST OF THE DAY GIVEN THE AMOUNT OF CAA AND LOW LEVEL MOISTURE. SKIES SHOULD CLEAR TUESDAY NIGHT...AND WEDNESDAY SHOULD BE A DRY DAY...HOWEVER A FEW INSTABILITY CU COULD POP IN THE AFTERNOON...ESPECIALLY OVER THE NORTHEAST...CLOSER TO THE WRAP-AROUND. WE WILL STAY CLOSE TO THE COOLER FAN NUMBERS FOR HIGHS ON TUESDAY AND GO WITH A MIX OF TEMPERATURES FOR THE REST OF THE PERIODS. THE EXTENDED LOOKS WET WITH A STRONG DIGGING UPPER LOW TO OUR SOUTHWEST EJECTING SHORT WAVES AT US. THANK YOU FOR THE COORDINATION DDC AND LB B.
