AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CARIBOU ME
1141 AM EDT FRI JUN 22 2012

.SYNOPSIS...
LOW PRESSURE WILL TRACK NORTH OF THE REGION TODAY SLOWLY PULLING A COLD
FRONT ACROSS THE STATE LATE TODAY THROUGH TONIGHT. SECONDARY LOW
PRESSURE WILL REDEVELOP IN THE GULF OF MAINE ON SATURDAY AND TRACK
EAST OF THE AREA SATURDAY NIGHT AND SUNDAY.
&&

.NEAR TERM /THROUGH TONIGHT/...
1140 AM UPDATE: SKIES ARE MOSTLY SUNNY ACROSS EASTERN AND SOUTHERN
AREAS SO STARTED THE AFTERNOON PARTLY TO MOSTLY SUNNY. A LONG OF
THUNDERSTORMS IS BUILDING OVER WESTERN AROOSTOOK COUNTY. THIS IS
EXPECTED TO EXPAND AND SPREAD EAST BRINGING THUNDERSTORMS WITH
HEAVY DOWNPOURS THIS AFTERNOON...ESPECIALLY ACROSS NORTHERN AND
CENTRAL AREAS.

ORGNL DISC: A LINE OF NOCTURNAL TSTMS IS ABOUT READY TO EXIT E OF
THE FA INTO NB PROV WITHIN THE NEXT HR OR TWO. FOLLOWING THIS WILL
BE A RELATIVE QUIET SPELL FEATURING SCT SHWRS AND ISOLD TSTMS AT
MOST THRU THE MORN HRS. A NEW LN OF SHWRS AND TSTMS WILL FORM
AHEAD OF A SLOW MOVG COLD FRONT FROM QB LATER THIS AFTN OVR WRN
PTNS OF THE FA AND SLOWLY PROPAGATE INTO ERN AREAS BY ERLY EVE.
ALTHOUGH SB CAPE IS FCST TO BE RELATIVELY HI AT ARND 1500-2000
J/KG AT MAX HTG THIS AFTN...LOW 0-6KM BULK SHEAR OF 20 TO 25
KT...RELATIVELY HIGH FZG LVLS SHOULD MSLY LIMIT HAIL AND WIND GUST
POTENTIAL...BUT SLOW BACKWARD CORFIDI VECTORS OF 10 TO 15 KTS LATE
TDY INTO THIS EVE COULD RESULT IN SLOW MOVING OR BACK BUILDING
TSTMS AND POSSIBLE LCLZD FLDG. TSTMS SHOULD DIMINISH TO MSLY SHWRS
LATE TNGT AFTER INSTABILITY FROM MAX DAYTIME HTG IS USED UP. HI
TEMPS TDY WITH LMTD SUNSHINE WILL BE COOLER THAN THE LAST 2
DAYS...BUT STILL AOA NORMAL. OVRNGT LOWS TNGT WILL BE A FEW DEG
COOLER THAN THE PREVIOUS NGT.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY/...
WITH THE FRONT STALLED IN THE EASTERN PART OF THE STATE...LOW
PRESSURE WILL FORM ON THE FRONTAL BOUNDARY IN THE GULF OF MAINE
AND TRACK TOWARDS THE BAY OF FUNDY SATURDAY INTO SATURDAY NIGHT.
THE SURFACE BOUNDARY...IN COMBINATION WITH AN UPPER TROUGH
BECOMING NEGATIVELY TILTED AND RATHER SHARP...WILL PROVIDE LIFT
FOR WIDESPREAD RAIN SHOWERS DURING SATURDAY FOR THE ENTIRE FORECAST
AREA. WITH SOME LIMITED AFTERNOON HEATING...SOME THUNDERSTORMS MAY
FORM AS THE UPPER TROUGH MOVES CLOSER TO THE FORECAST AREA AND
LAPSE RATES INCREASE. THE ENTRANCE REGION TO AN H300 JET MAY ALSO
BE AN ENABLING FACTOR FOR PM TSTMS. HIGHS WILL REACH THE LOW TO
MID 70S IN THE FORECAST AREA.

THE UPPER TROUGH SLOWLY CROSSES THE AREA SATURDAY NIGHT AND
INSTABILITY CONTINUES...LEADING TO CONTINUED MENTION OF ISOLATED
THUNDERSTORMS IN THE FORECAST. LOWS WILL BE IN THE MID TO UPPER
50S.  THE UPPER TROUGH WILL CONTINUE TO PROVIDE WEAK INSTABILITY
SUNDAY MORNING AND SLOWLY MOVE EASTWARD OUT OF THE FORECAST AREA
DURING THE AFTERNOON. CLOUD COVER WILL SLOWLY ERODE BY LATE
AFTERNOON...ALLOWING HIGHS TO CLIMB TO THE MID TO UPPER 70S.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
UNSETTLED CONDITIONS THROUGH THE PERIOD...
TRANSIENT HIGH PRESSURE MOVES QUICKLY THROUGH THE AREA SUNDAY
NIGHT INTO EARLY MONDAY. LOWS SUNDAY NIGHT WILL BE IN THE LOW TO
MID 50S. AN UPPER SHORTWAVE AND ASSOCIATED SURFACE LOW WILL
RAPIDLY MOVE FROM THE EASTERN GREAT LAKES REGION INTO SOUTHERN NEW
ENGLAND BY MONDAY AFTERNOON. THE SURFACE LOW WILL DEEPEN MONDAY
AND MONDAY NIGHT AS IT MOVES TOWARDS MAINE. VERTICAL MOTIONS
WITH THIS SYSTEM WILL PRODUCE SOME MODERATE RAINFALL MONDAY NIGHT
INTO TUESDAY. THE LOW WILL STALL OVER MAINE BY LATER TUESDAY AND PRODUCE
SHOWERY CONDITIONS INTO THURSDAY. THE GOOD NEWS IS THAT THE
SURFACE FRONT AND ASSOCIATED WARM CONVEYOR BELT IS CURRENTLY
EXPECTED TO MOVE EAST OF THE STATE WITH ITS FEED OF TROPICAL
MOISTURE MOVING NORTHWARD. THIS MEANS THAT THE POTENTIALLY HEAVY RAIN
FOR TUESDAY INTO THURSDAY IS MORE LIKELY TO STRIKE IN THE MARITIMES.
HOWEVER...THE EXACT ORIENTATION OF THE BROAD UPPER LOW CIRCULATION
AND BLOCKING HIGH IN THE ATLANTIC COULD STILL CHANGE. THUS THE
SITUATION WILL BEAR CAREFUL WATCH. THE SHOWERY AND CLOUDY PATTER
WILL PRODUCE HIGHS IN THE UPPER 60S TO LOW 70S AND LOWS IN THE MID
TO UPPER 50S DURING THIS PERIOD.

&&

.AVIATION /16Z FRIDAY THROUGH TUESDAY/...
NEAR TERM: VFR TDY...XCPT MVFR CLGS/VSBYS IN HEAVIER SHWRS AND
TSTMS LATER TDY INTO THIS EVE...AND THEN PATCHY TO AREAS OF FOG
LATE TNGT.

SHORT TERM: WIDESPREAD IFR CONDITIONS EARLY SATURDAY WILL LIFT TO
VFR BY AFTERNOON WITH TEMPO IFR IN SHOWERS AND THUNDERSHOWERS. IFR
TO MVFR CONDITIONS RETURN SATURDAY NIGHT AS SHOWERS AND THUNDERSHOWERS
CONTINUE. THE RESIDUAL MOISTURE STARTS SUNDAY IN MVFR...BUT WILL
LIFT TO VFR BY MIDDAY AND STAY VFR UNTIL MONDAY AFTERNOON WHEN
MVFR CONDITIONS MOVE IN FOR BGR AND BHB AND TEMPO THUNDERSTORMS
BECOME POSSIBLE NORTH OF HUL.
