AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CARIBOU ME
247 AM EDT SAT AUG 23 2014

.SYNOPSIS...
HIGH PRESSURE WILL CREST OVER THE AREA ON SUNDAY, THEN GRADUALLY
WEAKEN AND MOVE SOUTH OF THE AREA EARLY NEXT WEEK.
&&

.NEAR TERM /THROUGH TONIGHT/...
HIGH PRESSURE WILL CONTINUE TO BUILD INTO THE AREA. EARLY THIS
MORNING, WE HAVE PATCHY VALLEY RADIATION FOG OVER FAR NORTH/NORTHWEST
MAINE WHERE SKIES HAVE CLEARED. ELSEWHERE, THERE IS AN EXTENSIVE
LOW TO MID LEVEL CLOUD DECK. EXPECT THE CLOUDS TO GRADUALLY
DECREASE THROUGH THE DAY WITH PARTLY CLOUDY SKIES BY MIDDAY. JUST
ENOUGH INSTABILITY AND SOME WEAK LOW LEVEL CONVERGENCE COULD SPARK
SOME AFTERNOON SHOWERS OVER CENTRAL PORTIONS OF THE AREA RUNNING
FROM HOULTON AND CARIBOU SOUTHWEST TO THE MOOSEHEAD LAKE REGION.
NOTHING SIGNIFICANT AT ALL...JUST AN ISOLATED SHOWER. WINDS WILL
BE LIGHT TODAY OUT OF THE NORTHEAST WITH HIGHS A LITTLE WARMER
THAN YESTERDAY AND RUNNING MAINLY IN THE MID 70S.

PARTLY CLOUDY TO MOSTLY CLEAR TONIGHT WITH LOWS MAINLY IN THE
LOWER TO MID 50S.
&&

.SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
FOR SUNDAY...THE POWERFUL UPPER RIDGE WILL SLIDE EASTWARD WITH
WARM AIR ADVECTION PUSHING HIGHS INTO THE LOW 80S FOR MOST OF THE
AREA EXCEPT THE COAST WHERE UPPER 70S ARE FORECAST. A WEAK COLD
FRONT EXTENDING SOUTH FROM A LOW NORTH OF LABRADOR COULD SET OFF A
FEW SHOWERS TOWARDS THE EASTERN BORDER OF THE STATE LATER IN THE
AFTERNOON...BUT WILL ONLY GO WITH SLIGHT CHANCE POPS. SUNDAY NIGHT
WILL BE THE LAST COOLER NIGHT WITH LOWS IN THE MID 50S WITH LIGHT
WINDS AND CLEAR SKIES. AS THE UPPER LEVEL RIDGE CONTINUES TO
STRENGTHEN ON MONDAY...TEMPERATURES WILL BE WARMER YET WITH HIGHS
REACHING THE LOW TO MID 80S ACROSS THE AREA. SOUTHWEST WINDS
DEVELOP WITH SURFACE HIGH PRESSURE TO THE SOUTH. FAIR SKIES
CONTINUE INTO MONDAY NIGHT WITH LOWS AROUND 60F.
&&

.LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/...
THE UPPER RIDGE REMAINS IN PLACE FOR TUESDAY AND HIGHS WILL
INCREASE AGAIN TO THE UPPER 80S FOR MOST OF THE AREA. SOUTHWEST
WINDS INCREASE WITH GUSTS TO 20 MPH. THE UPPER RIDGE STARTS TO
BREAK DOWN TUESDAY NIGHT. A WEAK COLD FRONT IS EXPECTED TO
APPROACH FAR NORTHERN ZONES LATE TUESDAY NIGHT WITH A CHANCE OF
THUNDERSTORMS TOWARDS THE ST JOHN VALLEY. THIS FRONT WILL EASE
INTO NORTHERN ZONES WEDNESDAY AND PROVIDE THE THREAT OF STRONG
THUNDERSTORMS WEDNESDAY AFTERNOON. HIGHS WILL BE IN THE LOW TO MID
80S NORTH AND UPPER 80S FOR BANGOR AND LINCOLN. THE FRONT COULD BE
A SLOW MOVER WITHOUT MUCH COOL AIR ADVECTION. AS A RESULT...WILL
KEEP SHOWERS AND THUNDERSTORMS IN THE FORECAST FOR THURSDAY WITH
THE FRONT LINGERING OVER THE STATE. THE MOVEMENT OF A TROPICAL
SYSTEM NORTHWARD AHEAD OF THE COLD FRONT FURTHER COMPLICATES THE
FORECAST FOR LATE NEXT WEEK. THE GENERAL TREND FOR LATE WEEK WILL
BE UNSETTLED WITH SLIGHTLY COOLER TEMPERATURES.
&&

.AVIATION /07Z SATURDAY THROUGH WEDNESDAY/...
NEAR TERM: MAIN CHALLENGE IS PATCHY FOG THIS MORNING OVER THE
NORTH, WHERE SKIES HAVE CLEARED ENOUGH TO ALLOW FOG TO FORM AT
FRENCHVILLE AS OF 0630 UTC. PATCHY FOG ALSO POSSIBLE AT CARIBOU
AND PRESQUE ISLE WHERE PARTIAL CLEARING IS OCCURRING, BUT SOUTH OF
PRESQUE ISLE, THE EXISTING CLOUD DECK SEEMS TO BE REMAINING ABOVE
MVFR LEVELS AND PREVENTING ANY RADIATION FOG FROM FORMING.

BECOMING VFR EVERYWHERE BY MID MORNING AND REMAINING VFR TONIGHT
FOR MOST AREAS.

SHORT TERM: OUTSIDE OF PATCHY FOG NEAR SUNRISE...EXPECT VFR
CONDITIONS. THERE IS A CHANCE OF STRONG THUNDERSTORMS BY WEDNESDAY
AFTERNOON.
&&

.MARINE...
NEAR TERM: CONDITIONS REMAINING BELOW SMALL CRAFT LEVELS THROUGH TONIGHT.

SHORT TERM: NO SIGNIFICANT ISSUES EXPECTED. IN SPITE OF WARMING
TEMPERATURES...FOG IS NOT EXPECTED DURING THE PERIOD.
&&

.CAR WATCHES/WARNINGS/ADVISORIES...
ME...NONE.
MARINE...NONE.
