AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CARIBOU ME
1243 AM EDT THU OCT 30 2014

.SYNOPSIS...
A SECOND COLD FRONT IS EXPECTED LATER TONIGHT WITH SOME SHOWERS
THROUGH EARLY THURSDAY MORNING. RELATIVELY QUIET WEATHER THEN
SETS UP FOR THURSDAY INTO FRIDAY AS HIGH PRESSURE SETTLES INTO THE
REGION. A COASTAL STORM WILL LIKELY IMPACT THE REGION BY LATE
SATURDAY INTO SUNDAY.

&&

.NEAR TERM /THROUGH TODAY/...
1240 AM UPDATE...SHOWERS ARE RAPIDLY EXITING DOWNEAST MAINE AT
THIS HOUR AS THE COLD FRONT MOVES OFFSHORE. HAVE MADE SOME
ADJUSTMENTS TO POPS TO MATCH CURRENT RADAR TRENDS. ALSO ADDED
PATCHY FOG TO THE FORECAST FOR THE REMAINDER OF TONIGHT/EARLY
THURSDAY MORNING AS THERE WILL BE A PERIOD OF CLEARING SKIES
BEFORE DAYBREAK. NO OTHER CHANGES WERE NEEDED.

PREVIOUS DISCUSSION...
A SECOND COLD FRONT IS FORECAST TO MOVE ACROSS THE REGION TONIGHT
W/ANOTHER ROUND OF SHOWERS. FOG STILL HOLDING ON ACROSS THE
NORTHERN TIER THIS AFTERNOON MAINLY FROM CARIBOU NORTHWARD AND
ESPECIALLY ACROSS THE HIGHER TERRAIN W/THE WARM AIR ALOFT OVER THE
COOLER AIR IN THE BLYR. FURTHER S, JUST PATCHY FOG ATTM. RADAR
SHOWED A LINE OF SHOWERS ASSOCIATED ON THE LEADING EDGE OF THE
BOUNDARY. THE NAM12 AND RAP WERE DOING WELL W/PLACEMENT OF THE
SHOWERS AND DECIDED TO FOLLOW THIS BLEND INTO THE EVENING W/THE
SECOND PUSH OF SHOWERS. THE RAIN WILL PUSH OFFSHORE BY MIDNIGHT
TONIGHT. ADDITIONAL RAINFALL IS EXPECTED TO NO MORE THAN 0.25" AND
THIS WILL BE ACROSS THE CENTRAL HIGHLANDS AND INTERIOR DOWNEAST
SECTIONS. THE BLYR WILL MIX OUT LATER TONIGHT AS A WNW FLOW SETS
UP BEHIND THE FRONT W/SOME PARTIAL CLEARING ACROSS THE CENTRAL AND
DOWNEAST. BEFORE THEN, FOG COULD SET UP FOR A WHILE AND BECOME
DENSE BEFORE THE BLYR MIXES OUT. THIS WILL NEED TO BE MONITORED BY
THE EVENING CREW.

THE AIRMASS BEHIND THIS FRONT IS NOT THAT COLD, SO THE OVERNIGHT LOWS
WILL NOT DROP TOO FAR BELOW 40 ACROSS NORTHERN AND CENTRAL MAINE,
WHILE SOUTH/DOWNEAST WILL BE IN THE LOWER TO MID 40S. TEMPERATURES
ON THURSDAY WILL BE IN THE NORMAL RANGE AS COOLER AIR FILTERS INTO
THE REGION. STILL SOME PRETTY GOOD RH FROM 925-850MBS ON THURSDAY
TO ALLOW FOR CLOUDS DURING THE DAY LIMITING THE SUNSHINE ACROSS
THE NORTH AND WEST. DOWNSLOPE WILL AID IN MORE SUN FOR THE
DOWNEAST AND COAST.

&&

.SHORT TERM /TONIGHT THROUGH SATURDAY/...
A RIDGE AT THE SURFACE WILL BUILD IN FOR THURSDAY NIGHT WITH 
LIGHT NORTHERLY WINDS FILTERING IN COOLER AIR. EXPECT MAINLY
CLEAR SKIES DOWNEAST WITH SOME MID AND HIGH CLOUDS ACROSS THE
NORTH STREAMING NORTH AND EAST AHEAD OF DEVELOPING WAVE OVER THE
GREAT LAKES. EXPECT LOWS RANGING FROM THE UPPER 20S AND LOW 30S
ACROSS THE NORTH TO THE MID AND UPPER 30S DOWNEAST.

FRIDAY WILL CONTINUE TO BE QUIET AS A COMPLEX WEATHER SYSTEM
BEGINS TO ORGANIZE OFF TO THE SOUTH. SKIES LOOK TO BE MAINLY
CLOUDY IN THE NORTH WITH A MIX OF SUN AND CLOUDS DOWNEAST. HIGHS
WILL GENERALLY RANGE FROM THE LOW 40S NORTH TO THE UPPER 40S TO
AROUND 50 DOWNEAST.

THE FORECAST BECOMES MORE COMPLEX FOR FRIDAY NIGHT HEADING INTO
SATURDAY. A STRONG 500 MB SHORTWAVE WILL DIVE SOUTH AND EAST FROM
THE WESTERN GREAT LAKES TOWARD THE CAROLINA COAST DURING THIS TIME
WITH LOW PRESSURE AT THE SURFACE DEVELOPING OFF THE EAST COAST.
FORECAST MODELS ARE STILL STRUGGLING WITH THE EXACT EVOLUTION OF
THIS SYSTEM IN TERMS OF TRACK AND TIMING OF THE PRECIP ONSET.
EXPECT SOME LIGHT PRECIPITATION TO DEVELOP FROM SOUTH TO NORTH
EITHER LATE FRIDAY NIGHT OR DURING THE DAY SATURDAY. IF THIS
PRECIP COMES IN EARLY ENOUGH, IT MAY FALL AS A LITTLE SNOW AWAY
FROM THE COAST BEFORE GOING TO RAIN SATURDAY AS TEMPERATURES
MODERATE. AS THE LOW DRAWS CLOSER, PRECIP WILL HAVE THE POTENTIAL
OF BECOMING HEAVIER AND STEADIER BY LATE DAY SATURDAY INTO
SATURDAY NIGHT OVER EASTERN AREAS DEPENDING ON THE LOW'S TRACK...

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
LOW PRESSURE IS EXPECTED TO DEVELOP OFF THE MID ATLANTIC STATES
SATURDAY NIGHT THEN MOVE NORTHEAST TO NOVA SCOTIA DURING THE DAY
SUNDAY BASE ON OPERATIONAL GFS AND MOST GFS ENSEMBLE MEMBERS.
OPERATIONAL ECMWF BRINGS THIS SYSTEM CLOSER TO THE MAINE COAST.
STILL TO SOON TO MAKE CALL ON EXACT TRACK OF THIS SYSTEM. EXPECT
STRONG NORTHWEST FLOW AND COLDER AIR MASS MONDAY AS INTENSIFING
LOW MOVES TO THE NORTH. RIDGE IS EXPECTED TO CROSS THE STATE
TUESDAY. A COLD FRONT WILL APPROACH FROM THE WEST WEDESDAY.

&&

.AVIATION /06Z THURSDAY THROUGH MONDAY/...
NEAR TERM: CONDITIONS HAVE IMPROVED TO MOSTLY MVFR/VFR AT THE
TERMINALS AS OF 01Z. PATCHY IFR POSSIBLE IN SHOWERS/FOG FOR THE
NEXT SEVERAL HOURS ACROSS EASTERN MAINE. MAINLY VFR THURSDAY...BUT
POCKETS OF MVFR POSSIBLE ACROSS THE WESTERN MOUNTAINS AND FAR
NORTHERN MAINE. 

SHORT TO LONG TERM: MAINLY VFR FOR THURSDAY NIGHT THROUGH FRIDAY.
CONDITIONS DETERIORATING TO AT LEAST MVFR ARE LIKELY SATURDAY AS
RAIN OR A RAIN/SNOW MIX MOVES IN....IFR CONDITIONS ALSO EXPECTED
SUNDAY. VFR CODNITIONS MONDAY.

&&

.MARINE...
NEAR TERM: NO HEADLINES EXPECTED THROUGH THURSDAY. WIND GUSTS
COULD HIT 20 KTS LATER TONIGHT INTO THURSDAY ON THE BACKSIDE ON
THE FRONT AND COOLER AIR MOVING ACROSS THE WATERS. SEAS WILL
REMAIN 3-4 FT INTO THURSDAY. 

SHORT TO LONG TERM: 
NO HEADLINES ARE EXPECTED THROUGH FRIDAY. AS A COASTAL LOW
DEVELOPS AND MOVES NORTH SATURDAY WINDS AND WAVES WILL INCREASE
WITH HIGH END SCA TO EVEN GALE CONDITIONS POSSIBLE BY LATE
SATURDAY. HOWEVER IT SHOULD BE NOTED THERE IS STILL SOME
UNCERTAINTY REGARDING THE TRACK OF THE STORM WHICH WILL DETERMINE
THE MAGNITUDE OF THE WINDS AND WAVE HEIGHTS REACHED...
