ALZ065>069-FLZ007>019-026>029-034-030800- AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 253 PM EST FRI FEB 2 1996 18 UTC MAPS DATA SHOWS 1006 MB LOW 100 MILES SW OF AQQ. ISALOBARIC ANALYSIS SHOWS BEST 3-HOUR PRESSURE FALLS ACROSS NORTH FL (4 MB FALLS)...SO ETA/NGM LOOK REASONABLE IN TIMING & MOVEMENT OF SFC LOW. THIS MEANS COLD FRONT & PRECIP WILL CLEAR FA WELL BEFORE SUNRISE...THEN COLD AIR ADVECTION BEGINS...WITH BITTERLY COLD ARCTIC AIR ARRIVING SUNDAY MORNING (AND STAYING THRU MONDAY). LOOKS LIKE NGM/FWC GUIDANCE IS WAY TOO WARM. ETA 1000 MB TEMP FORECAST LOOKED MORE REASONABLE...AS DID FAN GUIDANCE. EVEN SO...I DECIDED TO GO COLDER THAN THIS GUIDANCE BASED ON ARCTIC OUTBREAKS OF THE PAST. THIS EVENT LOOKS SIMILAR TO THE OUTBREAKS OF DEC 1983 AND JAN 1985...WHERE THERE WAS A LOT OF SNOW AND COLD GROUND IN THE PLAINS TO KEEP ARCTIC AIR FROM MODIFYING. LOOKS LIKE LOWS WILL BE IN LOWER TEENS MONDAY MORNING. FIGURE` ITS BETTER TO GO ON THE COLD SIDE FOR AGRICULTURAL & EMERGENCY MANAGEMENT INTERESTS (WE HAVE ALREADY HAD CALLS ABOUT OPENING SHELTERS THIS WEEKEND). 1) 45/45/16/32 9000 2) 49/49/18/34 9000 3) 48/48/17/33 9000 FOURNIER
