AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE GRAY ME
1118 PM EDT MON APR 21 2014

.SYNOPSIS...
LOW PRESSURE APPROACHES FROM THE WEST TUESDAY...CROSSING THE AREA
TUESDAY NIGHT AND WEDNESDAY. HIGH PRESSURE BUILDING ACROSS THE
REGION WILL BRING FAIR WEATHER MID TO LATE WEEK. ANOTHER AREA OF
LOW PRESSURE TRACKING CLOSE TO OUR AREA BRINGS A THREAT OF SHOWERS
OVER THE WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
-- Changed Discussion --
.UPDATE...
MINOR CHANGES TO CURRENT FORECAST FOR INCREASING CLOUD COVER AND
ADJUSTMENTS TO OVERNIGHT MINIMUM TEMPERATURES. AREAS WHICH SAW THE
SEABREEZE TODAY ARE A GOOD 10 DEGREES BELOW COOLER THAN STATIONS
IN NEW HAMPSHIRE AND SW MAINE. ALSO THERE IS A POCKET OF VERY DRY
AIR /DEW POINTS IN THE TEENS STILL OVER SOUTHERN NH/ LEAVING
PLENTY OF ROOM FOR COOLING. THEREFORE LOWS WILL VARY FROM LOCATION
TO LOCATION EVEN AS WINDS DIE OFF AT MOST SITES. AREA OF
PRECIPITATION ASSOCIATED WITH FRONTAL BOUNDARY IS MOVING THROUGH
SOUTHERN QUEBEC AND NORTHERN NY STATE AND VT THIS HOUR AND WILL
REACH OUR REGION IN THE NEXT COUPLE OF HOURS. QPF WILL BE LIGHT.
ECHOES OFF THE COAST LIKELY THE RESULT OF ATMOSPHERIC DUCTING AND
ARE NOT PRECIPITATION.

PREVIOUS DISCUSSION...
A SHORT WAVE TROUGH AND ATTENDANT SURFACE LOW PRESSURE AREA WILL
APPROACH FROM THE WEST LATER TONIGHT. A FRONTAL BOUNDARY AHEAD OF
THE LOW CENTER WILL SAG INTO NORTHERN PORTIONS OF THE FORECAST
AREA TONIGHT. THIS BOUNDARY WILL BE THE FOCUS FOR SOME LIGHT
SHOWER ACTIVITY IN THE MOUNTAINS. OTHERWISE...A FAIR AND
RELATIVELY WARM NIGHT IS EXPECTED IN MOST AREAS.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/...
MUCH OF THE AREA WILL BE WARM-SECTORED FOR MUCH OF THE DAY
TUESDAY. DESPITE CLOUD COVER...TEMPERATURES SHOULD GET PRETTY
WARM...WITH READINGS AROUND 70 IN THE FAR SOUTH TO MID 50S IN THE
FAR NORTH AND ALONG THE IMMEDIATE COAST. LOW PRESSURE WILL
APPROACH LATE IN THE DAY AND THIS SHOULD ALLOW SHOWER ACTIVITY TO
SPREAD INTO OUR WESTERN ZONES DURING THE AFTERNOON.

WIDESPREAD SHOWERS CONTINUE TO BE EXPECTED TUESDAY NIGHT AS LOW
PRESSURE STRENGTHENS AND MOVES OVERHEAD.

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
SURFACE LOW PRESSURE MOVES THROUGH THE GULF OF MAINE TOWARD NOVA
SCOTIA WEDNESDAY... WITH UPPER LEVEL LOW PRESSURE OVER NEW
HAMPSHIRE AND MAINE. EXPECT SHOWERS TO CONTINUE ESPECIALLY FOR
EASTERN AREAS THROUGH THE DAY WEDNESDAY. NORTHWEST FLOW WILL BE
BRINGING COOLER AIR IN... AND ENHANCING THE PRECIPITATION
POTENTIAL IN UPSLOPE AREAS OF THE MOUNTAINS. SURFACE AND UPPER LOW
FINALLY MOVE OFF TO THE EAST WEDNESDAY NIGHT... BRINGING
PRECIPITATION POTENTIAL TO AN END.

COOL NORTHWEST FLOW CONTINUES THURSDAY WITH HIGHS REACHING THE 40S
AND 50S. HIGH PRESSURE RIDGES OVER THE AREA THURSDAY NIGHT INTO
FRIDAY. MAY SEE GOOD RADIATIONAL COOLING CONDITIONS FRIDAY MORNING
IN WESTERN NEW HAMPSHIRE... BUT WINDS MAY STAY UP FOR MUCH OF THE
NIGHT ACROSS MAINE... LIMITING OVERALL COOLING THERE. EXPECT A
LITTLE WARMER WEATHER FOR FRIDAY WITH THE RIDGE OVERHEAD AND
TEMPERATURES REACHING THE 50S TO NEAR 60 DEGREES. BUT ANOTHER
TROUGH MOVES IN FOR SATURDAY WITH MORE CHANCES FOR SHOWERS AND A
LITTLE COOLER WEATHER FOR THE WEEKEND.
