AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CARIBOU ME
300 PM EDT SAT AUG 25 2007
.SYNOPSIS...
LOW PRESSURE WILL LIFT ACROSS THE NORTH TONIGHT. A COLD FRONT
FOLLOWING THE LOW WILL PUSH INTO THE AREA LATE TONIGHT AND
THEN CONTINUE OFFSHORE DURING SUNDAY. HIGH PRESSURE WILL BUILD
OVER THE REGION MONDAY AND REMAIN IN THE AREA INTO WEDNESDAY. A
COLD FRONT WILL APPROACH LATE WEDNESDAY AND WEDNESDAY NIGHT.
&&
.NEAR TERM /THROUGH SUNDAY/...
MAIN CONCERN IN THE NEAR TERM WILL BE THE SEVERE WEATHER THREAT
FOR THE CWA LATE THIS AFTERNOON INTO EARLY TONIGHT. LATEST SURFACE
ANALYSIS INDICATES LOW PRESSURE NORTH OF NEW YORK STATE MOVING
EAST ALONG A NEAR STATIONARY FRONTAL BOUNDARY EXTENDING INTO NORTH
CENTRAL MAINE / K40B TO KHUL LINE/ ATTM. NORTH OF THE FRONT SKY
CONDITIONS CONSIST OF SC/AC WITH LIMITED HEATING TAKING PLACE WHILE
SOUTH OF THE BOUNDARY STRONG HEATING HAS OCCURRED WITH SURFACE
TEMPERATURES WELL INTO THE 80S /EVEN ALONG THE COAST/ ALONG WITH
DEW POINTS GENERALLY IN THE LOWER TO MID 70S.
OTHER THAN SOME WEAK WAA SHOWER OCCURRING ACROSS THE NORTHERN
ZONES...WEAK SURFACE RIDGING HAS KEPT CONVECTION LIMITED THROUGH
EARLY THIS AFTERNOON. AS THE ATMOSPHERE CONTINUES TO DESTABILIZE...
THE COMBINATION OF DEEP MOISTURE IN PLACE WILL INTERACT PROPAGATING
LOW LEVEL JET OF 40+ KTS TO ENHANCE LOW LEVEL CONVERGENCE AND
SHEAR ESPECIALLY IN THE VICINITY OF THE FRONTAL BOUNDARY. EXPECT
CONVECTION TO RAPIDLY DEVELOP OVER THE NEXT COUPLE OF HOURS WITH A
POSSIBLE WW BEING ISSUED FOR A PORTION OR ALL OF THE CWA.
EXPECT THE SEVERE THREAT TO DIMINISH LATE TONIGHT...HOWEVER THE
SURFACE COLD FRONT WILL BE SLOW TO MOVE SOUTHEAST ACROSS THE CWA
OVERNIGHT AND DURING SUNDAY. WILL HOLD ONTO MENTION OF TSTMS
ESPECIALLY DOWNEAST OVERNIGHT. SURFACE FRONT WILL BE SLOW TO
TRANSITION OFF THE COAST AND THROUGH THE COASTAL WATERS DURING
SUNDAY. LATEST SREF AND NAM GUIDANCE HOLDS ONTO A RIBBON OF CAPE
ACROSS INTERIOR AND COASTAL DOWNEAST DURING SUNDAY. WILL KEEP
CHANCE POPS GOING ACROSS THESE ZONES ALONG WITH THE MENTION OF
TSTMS AS WELL. FURTHER TO THE NORTH STILL EXPECT SOME SHOWERS AS
SHORT WAVE LIFTS ACROSS THE NORTHERN AND WESTERN ZONES DURING THE
MAXIMUM HEATING TIME OF SUNDAY.
&&
.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/...
HIGH PRESSURE WILL BUILD IN FROM THE NORTHWEST SUNDAY NIGHT
ALLOWING SKIES TO BECOME MOSTLY CLEAR. LIGHT WINDS AND MOIST
GROUND MAY RESULT IN SOME PATCHY FOG EARLY MONDAY MORNING.
OTHERWISE...MONDAY WILL BE SUNNY WITH LIGHT WINDS AND SEASONABLY
WARM TEMPERATURES AS THE HIGH BUILDS OVER. THE HIGH WILL SLIDE
JUST SOUTH OF THE REGION ON TUESDAY AS A WARM SOUTHWESTERLY FLOW
PUSHES TEMPERATURES TO NEAR 80 IN MANY AREAS. THIS WILL BE
FOLLOWED BY A MOSTLY CLEAR AND MILD NIGHT TUESDAY NIGHT.
&&
.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
COLD FRONT BEGINS TO APPROACH THE AREA ON WEDNESDAY WITH
INCREASING CLOUDS AND PRECIPITATION CHANCES AS THE DAY PROGRESSES.
MODELS SHOWING THIS FRONT SLOW TO MOVE ONCE OVER THE AREA WHICH
CAN STIR UP SOME SHOWERS FOR THURSDAY AS WELL. ONCE FRONT PASSES
ON THURSDAY NIGHT HIGH PRESSURE BUILDS IN AND COOLS THINGS DOWN
ACROSS THE CWA. HIGHS WILL BE AROUND 70 IN THE NORTH AND LOW 70S
DOWNEAST FOR FRIDAY AND SATURDAY. LOADED HPC GUIDANCE TO START AND
ONLY CHANGES MADE WERE TO LOWER POPS ON THURSDAY NIGHT AND FRIDAY.
&&
.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
VFR CONDITIONS EXPECTED TO START OUT AND AS THE LOW PRESSURE
SYSTEM APPROACHES WILL SEE SCATTERED MVFR CONDITIONS WITH ANY
SHOWERS AND THUNDERSTORMS. AS NIGHT WEARS ON WILL SEE A TREND
TOWARD IFR CEILINGS ACROSS THE REGION WITH AREAS OF MVFR.
VFR CONDITIONS ARE EXPECTED SUNDAY NIGHT THROUGH
TUESDAY NIGHT WITH THE POSSIBLE EXCEPTION OF SOME PATCHY FOG LATE
SUNDAY NIGHT AND AGAIN LATE MONDAY NIGHT...MAINLY IN THE VALLEYS.
&&
.MARINE...
WILL CONTINUE THE SCA HEADLINE FOR HAZARDOUS SEAS TONIGHT.
EXPECT WINDS TO PICK UP SOME IN ADVANCE OF APPROACHING SURFACE
COLD FRONT...HOWEVER WINDS SHOULD REMAIN BELOW HEADLINE CRITERIA
THROUGH SUNDAY.
WINDS AND SEAS ARE EXPECTED TO REMAIN BELOW SCA SUNDAY NIGHT
THROUGH MID WEEK.
