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.
