AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CARIBOU ME
329 AM EDT TUE APR 28 2015

.SYNOPSIS...
UPPER LEVEL LOW PRESSURE WILL KEEP UNSETTLED CONDITIONS ACROSS
THE REGION THROUGH EARLY THURSDAY. A BREAK IN THE UNSETTLED
WEATHER IS EXPECTED BY LATE IN THE WEEK AND POSSIBLY INTO THE
WEEKEND.

&&

.NEAR TERM /THROUGH TONIGHT/...
ANOTHER ROUND OF SHOWERS AND GUSTY WINDS FOR THIS TERM.

06Z SFC/UPPER ANALYSIS SHOWED LOW PRES SLOWLY MOVING SE OF NOVA
SCOTIA W/SHOWERS MOVING SSW BUT NOW DISSIPATING. JET MAX OF 40-50
KT FROM 850-700MBS HELPING TO TRIGGER THE SHOWERS AND GUSTY WINDS.
A BRIEF BREAK IN THE ACTION THIS MORNING AND THEN ANOTHER ROUND OF
SHOWERS EXPECTED TO MOVE IN FROM THE MARITIMES THIS AFTERNOON AND
CONTINUE INTO THE EVENING. WV SATELLITE IMAGERY SHOWED ANOTHER
SPOKE OF ENERGY THAT WILL AID THESE SHOWERS TO MOVE SSW TODAY FROM
THE MARITIMES. THE LATEST RUN OF THE 3KM HRRR AND THE NAM MATCHING
UP WELL W/THE LATEST CONDITIONS AS THE GFS. THEREFORE, DECIDED TO
INCREASE THE POPS FOR THE NORTHERN AND EASTERN AREAS AND EXPAND
THE AREAL COVERAGE AS WELL. TEMPERATURES WERE DOWN IN THE MID 30S
IN PORTIONS OF NORTHERN AND WESTERN AREAS W/DEWPOINTS IN THE LOWER
30S. PRECIP COULD FALL AS A MIX OF SNOW/RAIN OR EVEN SOME SLEET
THIS MORNING BEFORE TEMPERATURES WARM LATER THIS MORNING.
TEMPERATURES WILL WARM INTO THE 40S AND 50S BY THE AFTERNOON WILL
PRECIP IN THE FORM OF RAIN. SOUNDINGS INDICATE SOME INSTABILITY IN
THE LLVLS ESPECIALLY IN THE 0-3KM LAYER W/0-6KM SHEAR AROUND 40
KTS. WINDS WERE INCREASED TODAY TO ACCOUNT FOR THIS SETUP.

RAIN SHOWERS WILL CONTINUE ON AND OFF INTO EARLY TONIGHT AND THEN
BEGIN TO DIMINISH AFTER MIDNIGHT AS LLVL CONVERGENCE AND MID LEVEL
FORCING WEAKEN. TEMPERATURES ARE FORECAST TO DROP BACK INTO THE
30S OVERNIGHT W/RAIN FOR THE MOST PART. THE EXCEPTION TO THIS WILL
BE THE HIGHER ELEVATIONS SAY ABOVE 1000 FT AS SOME SNOW COULD MIX
IN BY EARLY WEDNESDAY MORNING. RAINFALL AMOUNTS ARE FORECAST TO BE
LESS THAN 0.10 INCHES W/EASTERN AREAS NEAR THE MAINE-NEW
BRUNSWICK BORDER SEEING UP TO 0.25 INCHES.

&&

.SHORT TERM /WEDNESDAY THROUGH THURSDAY/...
THE UPPER LEVEL LOW THAT HAS BROUGHT UNSETTLED WEATHER CONDITIONS
TO THE REGION FOR THE PAST SEVERAL DAYS WILL FINALLY BEGIN TO
LOSE ITS GRIP ON THE AREA DURING THE SHORT TERM PERIOD. WE COULD
STILL SEE A FEW ISOLATED SHOWERS AROUND INTO WEDNESDAY. OTHERWISE
EXPECT THE UPPER LOW TO BE REPLACED BY RIDGING BOTH AT THE SURFACE
AND ALOFT. THIS WILL BRING DRY WEATHER TO THE REGION WEDNESDAY
NIGHT AND THURSDAY. HIGHS BOTH WEDNESDAY AND THURSDAY WILL BE IN
THE LOW TO MID MID 50S ACROSS THE REGION. THE LOWS TUESDAY NIGHT
WILL BE IN THE UPPER 30S TO NEAR 40 DEGREES.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
MAINLY DRY WEATHER AND MODERATING TEMPERATURES CAN BE EXPECTED
THROUGH THE LONG TERM. HIGH TEMPERATURES WILL CONTINUE TO MODERATE
OVER THE WEEKEND AND INTO EARLY NEXT WEEK. BY EARLY NEXT WEEK WE
COULD BE LOOKING AT HIGHS REACHING CLOSE TO 70 DEGREES IN SOME
AREAS.

&&

.AVIATION /07Z TUESDAY THROUGH SATURDAY/...
NEAR TERM: MVFR THIS MORNING W/PERIODS OF VFR. MVFR CONDITIONS
FORECAST TO RETURN FOR THE NORTHERN TERMINALS LATER THIS MORNING
INTO THE AFTERNOON WHILE KBGR AND KBHB ARE EXPECTED TO SEE
CONDITIONS GO TO VFR. ALL TERMINALS TO EXPERIENCE VFR INTO EARLY
TONIGHT AND THEN CONDITIONS COULD DROP BACK TO MVFR BY EARLY
WEDNESDAY MORNING AS LOWER CIGS MOVING IN FROM NEW BRUNSWICK.

SHORT TERM: VFR CONDITIONS ARE EXPECTED THROUGH MOST OF THE
PERIOD.

&&

.MARINE...
NEAR TERM: WINDS/SEAS RIGHT SCA LEVELS AND WINDS TO PICK UP AFTER
12Z(8AM). THE SMALL CRAFT ADVISORY WILL STAY AS IS FOR NOW BUT
MAY NEED TO BE EXTENDED A FEW MORE HRS W/THAT SECOND SURGE OF WIND
MENTIONED ABOVE. SOME OF THE SOUNDING DATA ESPECIALLY THE NAM
SHOW A BRIEF SURGE OF WINDS THIS AFTERNOON ESPECIALLY AT THE
JONESPORT BUOY(44027). THIS SURGE LOOKS LIKE IT DROPS OFF AFTER
00Z(8PM) AS WINDS DROP OFF TO 15-20 KTS. SEAS ARE EXPECTED TO DOWN
TO 2-4 FT.

SHORT TERM: WIND/SEAS SHOULD REMAIN BELOW SMALL CRAFT LEVELS
WEDNESDAY THROUGH FRIDAY. SEAS MAY THEN INCREASE THE SMALL CRAFT
LEVELS BY THE WEEKEND AS AN OCEAN STORM TRACKS TO OUR EAST.
