AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CARIBOU ME
522 AM EDT FRI MAY 24 2013

.SYNOPSIS...
-- Changed Discussion --
A SLOW MOVING COLD FRONT WILL CONTINUE TO MOVE ACROSS THE AREA
TODAY. AN AREA OF LOW PRESSURE WILL MOVE NORTHEAST ALONG THIS
SURFACE BOUNDARY BRINGING PERIODS OF RAIN TO THE AREA THROUGH THE
WEEKEND.
-- End Changed Discussion --

.NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --
THE FORECAST HAS NOT REALLY CHANGED MUCH OVER THE LAST SEVERAL
DAYS. A COLD FRONT WILL CONTINUE ITS SLOW TREK EAST-SOUTHEAST
ACROSS THE REGION TOWARD THE GULF OF MAINE. THIS FRONT IS
ASSOCIATED WITH AN UPPER LEVEL TROUGH APPROACHING THE EAST COAST.
SMALL DISTURBANCES EMBEDDED WITHIN DEEP SUBTROPICAL MOISTURE
STREAMING NORTH AHEAD OF THE UPPER LEVEL TROUGH COMBINED WITH THE
BROAD SCALE LIFT ASSOCIATED WITH THE UPPER LEVEL TROUGH WILL
CONTINUE TO PRODUCE WIDESPREAD RAIN. PWATS ARE GENERALLY 1.5
INCHES AHEAD OF THE APPROACHING SURFACE BOUNDARY. NONE OF THE
DISTURBANCES ARE VERY STRONG SO EXPECT ANY PERIODS OF HEAVY RAIN
TO MAINLY BE AN EFFECT OF OROGRAPHIC LIFT RATHER THAN A COMPLEX OF
STORMS, IN FACT LITTLE OR NO THUNDER IS EXPECTED. DESPITE THE
RAINFALL...WIDESPREAD FLOODING WILL NOT BE AN ISSUE.

DUE TO THE WIDESPREAD RAIN, ABUNDANT CLOUD COVER AND THE FACT THAT
COOLER AIR IS FILTERING IN ACROSS THE REGION BEHIND THE SURFACE
BOUNDARY...DAYTIME TEMPS ARE EXPECTED TO REACH ONLY THE 50S AND
LOWER 60S TODAY. MIN TEMPS TONIGHT SHOULD BE MAINLY IN THE 40S AND
50S.

.SHORT TERM /SATURDAY THROUGH SUNDAY/...
-- Changed Discussion --
A SLOW MOVING LOW PRESSURE SYSTEM WILL CONTINUE TO BRING A VERY
RAINY AND COOL WEEKEND TO THE AREA. MODELS HAVE COME INTO GOOD
AGREEMENT IN THE OVERALL EVOLUTION OF THE SYSTEM WITH MOST OF THE
DIFFERENCES BEING IN SPECIFIC DETAILS SUCH AS THE PLACEMENT OF THE
HEAVIEST QPF DURING SPECIFIC PERIODS. GENERALLY, UTILIZED A MODEL
BLEND FOR THE FORECAST BUT WEIGHTED THE BLEND A BIT HEAVIER TOWARD
THE GEM AND GFS.

FOR SATURDAY, EXPECT THE STEADIEST AND HEAVIEST RAIN TO SLOWLY MIGRATE
NORTH THROUGH THE DAY. RAIN CONTINUES SATURDAY NIGHT, HEAVIEST AND
STEADIEST NORTH AND WEST, AS LOW PRESSURE SLOWLY DRIFTS NORTH
ALONG THE MAINE COAST. DURING THE DAY SUNDAY THE LOW CONTINUES
DRIFTING NORTH AND MOVES INTO NEW BRUNSWICK. AS MOISTURE CONTINUES
TO WRAP AROUND THE CLOSED CIRCULATION BOTH AT THE SURFACE AND
ALOFT THE HEAVIEST AND STEADIEST PRECIPITATION WILL TEND TO SET UP
OVER CENTRAL AND EASTERN PARTS OF THE CWA. EXPECT GENERAL RAIN
TOTALS THROUGH THE PERIOD STARTING SATURDAY MORNING LASTING
THROUGH THE DAY SUNDAY TO GENERALLY BE AT LEAST THREE QUARTERS OF
AN INCH TO AN INCH EXCEPT A BIT LESS ALONG THE COAST. DUE TO THE
AREA OF HEAVIEST RAINFALL TENDING TO SHIFT WITH TIME OVER THE
PERIOD NOT EXPECTING ANY SIGNIFICANT HYDRO ISSUES. ONLY EXPECTING
HIGH TEMPERATURES BOTH SATURDAY AND SUNDAY TO BE IN THE 40S TO LOW
50S, COOLEST NORTH AND WEST AND WARMEST SOUTH AND EAST, WITH LOWS
SATURDAY NIGHT IN THE LOW TO MID 40S.
-- End Changed Discussion --

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
-- Changed Discussion --
EXPECT SLOW IMPROVEMENT DURING THE EARLY TO MIDDLE PART OF THE
WEEK. THE HEAVIEST AND STEADIEST RAIN MOVES OUT SUNDAY NIGHT
NIGHT BUT MONDAY WILL STILL BE COOL AND GRAY WITH LINGERING
SCATTERED SHOWERS, ESPECIALLY EAST. HIGH PRESSURE FINALLY MOVES IN
FOR TUESDAY BRINGING SUNSHINE AND WARMER TEMPERATURES. CLOUDS
INCREASE WEDNESDAY WITH THE NEXT SYSTEM BRINGING THE CHANCE OF
SHOWERS BY WEDNESDAY NIGHT INTO THURSDAY.
-- End Changed Discussion --

.AVIATION /08Z FRIDAY THROUGH TUESDAY/...
-- Changed Discussion --
NEAR TERM:WIDESPREAD MVFR/IFR CONDITIONS STILL EXPECTED ACROSS THE
REGION THROUGH MUCH OF TODAY ALTHOUGH CIGS MAY RAISE TO VFR DURING
THE AFTERNOON...ESPECIALLY ACROSS FAR NORTHERN MAINE. CIGS/VSBY
WILL LIKELY ONCE AGAIN DROP TO IFR/MVFR OVERNIGHT...ESPECIALLY
ACROSS SOUTHERN TERMINALS WHICH WILL BE CLOSER TO THE BOUNDARY.
PERIODS OF RAIN ARE EXPECTED THROUGH THE TIME FRAME.

SHORT TERM:
EXPECT IFR/LIFR CONDITIONS TO PREDOMINATE THROUGH THE WEEKEND DUE
TO LOW CLOUDS, RAIN, AND AREAS OF FOG. BY MONDAY CONDITIONS
SHOULD IMPROVE TO AT LEAST MVFR, ESPECIALLY SOUTH. ALL AREAS WILL
BE VFR BY TUESDAY.
-- End Changed Discussion --

.MARINE...
-- Changed Discussion --
NEAR TERM:
WINDS/SEAS WILL CONTINUE TO BE IN THE SMALL CRAFT ADVISORY LEVEL
THROUGH TODAY. WINDS WILL DECREASE OVERNIGHT BUT EXPECT THE SWELL
TO INCREASE WITH THE APPROACHING LOW PRESSURE SYSTEM. WILL HOLD ON
TO THE SCA FOR WINDS/SEAS THROUGH TONIGHT...ALTHOUGH WOULD NOT BE
SURPRISED IF LATER SHIFTS TRANSITIONED TO SCA FOR SEAS ALONE.
OTHERWISE VISIBILITY MAY BE REDUCED AT TIMES IN RAIN/FOG.


SHORT TERM:
WINDS SHOULD BE BELOW SCA LEVELS OVER THE WEEKEND INTO
EARLY NEXT WEEK AS THE GRADIENT SLACKENS. HOWEVER EXPECT THE SWELL
TO PERSIST RESULTING IN SCA CONDITIONS DUE TO HIGH SEAS THROUGH
SUNDAY BEFORE DIMINISHING MONDAY. VISIBILITIES WILL BE REDUCED
OVER THE WEEKEND DUE TO RAIN AND AREAS OF FOG.
