FXUS62 KFFC 151132 AAA AFDFFC AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE PEACHTREE CITY GA 635 AM EST THU JAN 15 2015 .SHORT TERM /TODAY THROUGH FRIDAY/... FAST MOVING SHORT WAVE WILL SWEEP ACROSS THE REGION TODAY...ONLY VERY WEAK SURFACE REFLECTION ASSOCIATED WITH THIS AND MOISTURE IS SOMEWHAT LIMITED. PRECIPITATION SHOULD BEGIN SPREADING INTO WESTERN PORTIONS OF THE FORECAST AREA LATE THIS MORNING AND PUSH OUT OF THE AREA BY EARLY EVENING. VERTICAL TEMPERATURE PROFILES KEEP THE LOWER 5-7KFT OF THE ATMOSPHERE ABOVE FREEZING DURING THIS TIME PERIOD SO I AM NOT INCLUDING ANY SNOW IN THE FORECAST ACROSS NORTH GEORGIA WITH THIS SYSTEM. AS THE PRECIPITATION IS ENDING THIS EVENING THICKNESS VALUES ACROSS THE FAR NORTH ARE BORDERLINE...BUT PRECIPITATION SHOULD BE ENDED BEFORE ANY CHANGE-OVER OCCURS. THIS WILL NEED TO BE WATCHED CLOSELY FOR ANY CHANGES THROUGH THE DAY. MOSTLY SUNNY WITH A SLIGHT WARM-UP EXPECTED FRIDAY...WHICH WILL BE A NICE CHANGE OF PACE FROM THE PAST SEVERAL DAYS. EARLY THIS MORNING...GENERALLY FROM NOW THROUGH AROUND 9AM... ISOLATED PATCHES OF DENSE FOG ACROSS NORTH GEORGIA WITH TEMPERATURES AROUND FREEZING MAY PRODUCE SOME LIGHT FREEZING FOG. ISOLATED NATURE OF ANY DENSE FOG SHOULD KEEP THIS FROM CAUSING ANY WIDESPREAD TRAVEL PROBLEMS...HOWEVER I HAVE ISSUED A SPECIAL WEATHER STATEMENT FOR NORTH GEORGIA FOR THE SMALL POTENTIAL FOR ISOLATED SLICK SPOTS ON BRIDGES AND OVERPASSES. 20 .LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/... DRY NORTHWEST TO WEST FLOW DOMINATES THE AREA THROUGH EARLY SUNDAY. THE NEXT SHORT WAVE MOVES ACROSS THE SOUTHEAST DURING THE DAY SUNDAY. THE SOUTHERN EXTENT OF THE MOISTURE CONTINUES TO LOOK LIMITED...SO HAVE BEST POPS FOR THE EXTREME NORTH WITH ONLY SLIGHT CHANCE ELSEWHERE. THIS SYSTEM MOVES THROUGH RAPIDLY AND SUNDAY NIGHT THROUGH TUESDAY LOOK DRY. ZONAL FLOW ALOFT BEGINS TO BRING MOISTURE BACK ACROSS THE FORECAST AREA AT THE END OF THE PERIOD. A SHORT WAVE CROSSING THE TN VALLEY COULD BRING A BRIEF PERIOD OF RAIN TO THE EXTREME NORTH TUESDAY NIGHT...BUT THE ECMWF SEEMS DRIER WITH THIS SYSTEM. AT THIS TIME...HAVE KEPT THE POPS ONLY SLIGHT CHANCE AND HAVE KEPT A MENTION OF A MIX OF LIGHT RAIN/SNOW FOR THE NORTHEAST. EXTENT OF WINTRY MIX SEEM LIMITED AT THIS TIME. 41 && AVIATION... 12Z UPDATE... WIDE MIXTURE OF LIFR TO VFR CONDITIONS ACROSS THE FORECAST AREA AT THIS TIME.
