AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CARIBOU ME
310 PM EDT SAT JUL 20 2013

.SYNOPSIS...
A STRONG COLD FRONT WILL CROSS THE REGION TONIGHT. A DRIER AND
COOLER CANADIAN AIRMASS WILL THEN BUILD INTO THE AREA ON SUNDAY
AND HOLD OVER THE REGION THROUGH MONDAY. THE NEXT LOW PRESSURE

INTO TUESDAY.

&&

.NEAR TERM /THROUGH SUNDAY/...
A COLD FRONT WILL MOVE THROUGH THE REGION OVERNIGHT FOLLOWED BY
CANADIAN HIGH PRES FOR SUNDAY. THIS HIGH WILL REMAIN IN CONTROL
THROUGH EARLY NEXT WEEK.

SOME CONVECTION HAS FIRED UP MAINLY ACROSS NORTHERN AND WESTERN
AREAS(SUB-SEVERE) AS SOME UPPER LEVEL DIVERGENCE SEEN ON THE SATL
WV IMAGERY AND 12Z UA. THE BEST SHOT FOR ANY STRONGER STORMS WILL
BE ACROSS THE DOWNEAST AND COAST INTO THE EVENING AND THEN
ACTIVITY WILL WEAKEN. THE BEST FORCING AND INSTABILITY WILL SHIFT
TO THE EAST. ADDED SOME FOG TO THE GRIDS FOR TONIGHT INTO EARLY
SUNDAY MORNING BASED ON ANTICIPATED CLEARING AND COOLER TEMPERATURES
W/A WET GROUND. ADJUSTED THE OVERNIGHT LOW USING A BLEND OF THE NAM12
AND ECMWF. POPS ARE A BLEND OF THE RUC AND DOWNSCALED NAM WHICH
SHOW PRECIP CHANCES WINDING DOWN AFTER 00Z.

SUNDAY LOOKS TO BE SUNNY AND PLEASANT W/HIGH PRES BUILDING IN FROM
CANADA. THINKING ATTM IS TO TAKE W/CONSISTENCY AND KEEP THE

70S CENTRAL AND DOWNEAST.

NEW ENGLAND. CLOUDS WILL CONTINUE TO INCREASE MONDAY NIGHT AND
SOME RAIN MAY SPREAD INTO THE AREA LATE. THE BEST CHANCE FOR RAIN
WILL BE ALONG THE FRONTAL BOUNDARY WHICH WILL BE NEAR THE COAST.
THE LOW WILL TRACK JUST OFFSHORE ON TUESDAY BRINGING A CHANCE OF
RAIN TO THE AREA. THE BEST CHANCE FOR RAIN WILL BE ALONG COASTAL
AREAS. A COLD FRONT WILL APPROACH THE WEST LATE IN THE DAY. WARM
AND HUMID AIR MOVING NORTH AHEAD OF THE FRONT BENEATH RELATIVELY
COOLER AIR ALOFT MAY PRODUCE SOME THUNDERSTORMS IN WESTERN AREAS
LATE IN THE DAY.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
A WEAK LOW WILL BE TRACKING OFF THE COAST TUESDAY NIGHT AS A COLD
FRONT APPROACHES FROM THE WEST. THE LOW MAY BRING SOME RAIN TO
COASTAL AREAS EARLY TUESDAY NIGHT WHILE THE APPROACHING FRONT
BRINGS SOME SHOWERS AND POSSIBLY THUNDERSTORMS TO FAR WESTERN
AREAS. THE FRONT IS EXPECTED TO CROSS THE AREA EARLY WEDNESDAY
BRINGING SOME SHOWERS AND ISOLATED THUNDERSTORMS MAINLY TO THE
DOWNEAST REGION. HIGH PRESSURE SHOULD THEN BRING DRIER AIR WITH
CLEARING LATER WEDNESDAY INTO THURSDAY. ANOTHER FRONT MAY APPROACH
LATER FRIDAY INTO SATURDAY WITH INCREASED HUMIDITY FRIDAY INTO
SATURDAY.

&&
