AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AMARILLO TX
545 AM CST MON 23 DEC 2002

PRECIPITATION HAS BROKEN OUT ACROSS THE PANHANDLES THIS MORNING AS
BROAD AREA OF MID-LEVEL LIFT AND UPPER LEVEL DIFFLUENCE SPREADS OVER
THE SOUTHERN PLAINS IN ADVANCE OF STRONG MID/UPPER LEVEL LOW TO THE
WEST. SHORT RANGE MODELS STILL APPEAR TO BE HAVING A TOUGH TIME
DEALING WITH MID/UPPER LEVEL LOW...EITHER DEPICTING A DEEP TROUGH OR
A VERY WEAKLY CLOSED MID LEVEL LOW AT BEST. HOWEVER...PER ANALYSIS
OF UPPER AIR DATA AND WV IMAGERY IT SEEMS THAT MID LEVEL CIRCULATION
MAY BE A BIT MORE CLOSED OFF THAN MODELS ARE INDICATING. ALSO...
MODELS APPEAR TO HAVE UNDERESTIMATED STRENGTH OF JET STREAK DIVING
SOUTH OFF THE COAST OF SOUTHERN CALIFORNIA...WHICH WOULD SUGGEST
THAT THE MID-LEVEL CIRCULATION WOULD REMAIN CLOSED A LITTLE LONGER.
PRIMARY IMPACT TO THE PANHANDLES DUE TO THE ABOVE DISCREPANCIES
WOULD BE REFLECTED IN INTENSITY AND DURATION OF PRECIPITATION.
CONSIDERING THE AFOREMENTIONED OBSERVATIONS FORECAST PACKAGE WAS
BASED TOWARDS THE TREND OF A SLIGHTLY SLOWER SOLUTION. SEVERAL HOURS
OF RUC40/LAPS ANALYSIS CONTINUE TO SHOW VERY STRONG ISENTROPIC
UPGLIDE AND STRONG 700-500MB DIV-Q VALUES ACROSS THE AREA WHICH IS
STRONGER THAN WHAT LAST EVENINGS SHORT RANGE MODELS WERE INDICATING.
ANOTHER SIGN OF A SYSTEM MORE INTENSE THAN EXPRESSED BY THE MODELS.
THEREFORE...SHIFT TEAM DECIDED TO INCLUDE ALL OF THE TX/OK PANHANDLES
IN A HEAVY SNOW WARNING FOR BOTH TODAY AND TONIGHT WITH UP TO 10
INCHES IN THE NE TX PANHANDLE BY TUESDAY MORNING...AND CONTINUE WITH
A CHANCE OF SNOW ON TUESDAY.

AFTER TUESDAY ONLY SOME MINOR CHANGES WERE MADE TO FORECAST. SHOULD
BE PARTLY TO MOSTLY CLOUDY AND DRY. SNOW COVER WILL LIKELY TEMPER
WARMING TREND TO A VERY GRADUAL RATE THROUGH THE WEEKEND.
