000 FXUS61 KCAR 242143 AFDCAR AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CARIBOU ME 443 PM EST MON NOV 24 2014 .SYNOPSIS... LOW PRESSURE WILL TRACK WELL NORTHWEST OF THE REGION TONIGHT. A COLD FRONT WILL CROSS THE REGION TONIGHT WITH A SECOND COLD FRONT CROSSING THE REGION TUESDAY. LOW PRESSURE WILL LIFT ACROSS THE GULF OF MAINE WEDNESDAY NIGHT THEN EXIT ACROSS THE MARITIMES THURSDAY. && .NEAR TERM /THROUGH TUESDAY/... LOW PRESSURE WILL TRACK ACROSS NORTHWEST QUEBEC PROVINCE TOWARD LABRADOR TONIGHT. SCATTERED RAIN SHOWERS ARE POSSIBLE ACROSS THE ENTIRE REGION EARLY TONIGHT...WITH ISOLATED RAIN SHOWERS LINGERING ACROSS NORTHERN AREAS OVERNIGHT. ABUNDANT LOW LEVEL MOISTURE WILL REMAIN ACROSS THE ENTIRE FORECAST AREA TONIGHT SUPPORTING AREAS OF DRIZZLE AND FOG. A SECONDARY COLD FRONT/TROF WILL CROSS THE REGION TUESDAY WITH PARTLY/MOSTLY CLOUDY SKIES NORTH AND PARTLY CLOUDY SKIES ACROSS CENTRAL AND DOWNEAST PORTIONS OF THE FORECAST AREA.

COOLER AIR FILTERS IN ON WESTERLY FLOW TUESDAY NIGHT AND EARLY WEDNESDAY, WITH PERHAPS A FEW LIGHT SNOW SHOWERS OVER THE NORTH TUESDAY EVENING. ALL EYES THEN TURN TO A POTENTIAL HIGH IMPACT WINTER STORM. HAVE ISSUED WINTER STORM WATCH SOUTH/EAST OF A HOULTON, MILLINOCKET, GREENVILLE LINE LATE WEDNESDAY AFTERNOON TO THURSDAY MORNING. ALTHOUGH THERE ARE STILL SOME MODEL DISCREPANCIES, MODELS HAVE COME INTO GOOD ENOUGH AGREEMENT TO GO AHEAD AND ISSUE A WINTER STORM WATCH. ECMWF CONTINUES TO HAVE THE FURTHER WEST TRACK AND THE HEAVIEST SNOW TOTALS, WHILE MOST OTHER MODELS ARE A BIT FURTHER SOUTH AND EAST. WENT WITH A COMPROMISE APPROACH FOR QPF AND SNOW TOTALS. CURRENT TRACK WOULD MEAN MOSTLY SNOW EXCEPT FOR A RAIN SNOW MIX RIGHT ALONG THE COAST EARLY WEDNESDAY EVENING BEFORE CHANGING TO ALL SNOW. ANY RAIN THAT FALLS LATE WEDNESDAY AFTERNOON AT THE ONSET WILL QUICKLY CHANGE OVER TO SNOW DUE TO LOW DEWPOINTS AND EVAPORATIVE COOLING. WIND DOESN`T APPEAR TO BE TOO BIG OF A DEAL WITH THIS SYSTEM. THERE MAY BE ENOUGH WIND FOR A BIT OF BLOWING AND DRIFTING WITH SOME GUSTS TO 30 MPH, BUT WIND DOES NOT LOOK TO BE AS STRONG AS WITH THE STORM BACK AT THE BEGINNING OF THE MONTH. SOMETHING WE EMPHASIZED IN THE WINTER STORM WATCH AND WILL EMPHASIZE HERE: IF YOUR TRAVEL PLANS ARE FLEXIBLE AT ALL, GO EARLY! PRECIPITATION DOESN`T BEGIN IN NORTHERN/EASTERN MAINE UNTIL LATE WEDNESDAY AFTERNOON. TO BE SAFE, IF YOUR DESTINATION IS IN NORTHERN/EASTERN MAINE, AIM TO ARRIVE BY MID AFTERNOON. IF YOU ARE TRAVELING TO POINTS SOUTHWEST OF BANGOR, YOU NEED TO TRY TO ARRIVE EARLIER. THE PRECIPITATION BEGINS BY MIDDAY WEDNESDAY FOR POINTS FURTHER SOUTHWEST IN NEW ENGLAND. IF YOUR DESTINATION IS SOUTHWEST OF MAINE, TRAVELING TUESDAY INSTEAD OF WEDNESDAY MAY BE WISE. THE SNOW WILL TAPER OFF FROM WEST TO EAST LATE WEDNESDAY NIGHT OR EARLY THURSDAY MORNING. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... COLD AIR MOVES IN ON THE BACK SIDE OF THE STORM FOR THURSDAY THROUGH FRIDAY NIGHT. FRIDAY NIGHT, IT COULD APPROACH ZERO IN SOME AREAS IF HIGH PRESSURE SETS UP JUST RIGHT. THEN THE AIRMASS QUICKLY WARMS SATURDAY AND SUNDAY WITH A CHANCE OF RAIN, SNOW, AND PERHAPS EVEN SOME FREEZING RAIN DURING THE TRANSITION. DOES NOT LOOK LIKE A SIGNIFICANT STORM, HOWEVER. THEN DRYING OUT AND COOLING DOWN EARLY NEXT WEEK. && .AVIATION /21Z MONDAY THROUGH SATURDAY/... NEAR TERM...IFR/LIFR CONDITIONS WILL OCCUR ACROSS THE ENTIRE REGION THROUGH THE EARLY MORNING HOURS.
