Area forecast discussion, Feb 25, 12:06 PM EST, 42 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAY ME
1206 PM EST THU FEB 25 2016

.SYNOPSIS...
LOW PRESSURE WILL DRAG A TRAILING COLD FRONT ACROSS THE AREA
TODAY...PRECEDED BY A SOUTHERLY FLOW AND RECORD BREAKING WARMTH.
BEHIND THE FRONT TEMPERATURES WILL RETURN TO SEASONAL LEVELS ON
FRIDAY. ANOTHER LOW PRESSURE SYSTEM WILL PASS NORTH OF THE REGION
SUNDAY NIGHT AND MONDAY AND WILL DRAG A COLD FRONT ACROSS THE
REGION LATE MONDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...

1202 PM...THE RECORD HIGHS AT BOTH PORTLAND AND CONCORD WERE
ECLIPSED THIS MORNING. FOR THIS ESTF UPDATE...I MADE MINOR
ADJUSTMENTS TO NEAR TERM GRIDS THAT REFLECT RADAR AND SATELLITE
TRENDS AND TO INGEST THE CURRENT MESONET.

PREV DISC...
935 AM...FOR THIS ESTF UPDATE I MADE ADJUSTMENTS TO NEAR TERM
GRIDS TO REFLECT RADAR AND SATELLITE TRENDS AND TO INGEST 14ZS
MESONET. TEMPERATURES CONTINUE TO CLIMB IN SOUTHERLY FLOW AHEAD OF
THE COLD FRONT OVER WESTERN NEW ENGLAND. THE CHALLENGE IS TIMING
WHEN WE MIX OUT AT A PARTICULAR LOCATION...WHICH RESULTS IN RAPID
JUMPS IN SURFACE TEMPERATURES. THE RECORD HIGH AT PORTLAND /51F
SET IN 1985/ HAS ALREADY BEEN BROKEN. THE RECORD AT CONCORD / 60F
SET IN 1984/ WILL BE CHALLENGED AS WELL.

PREV DISC...
UPDATE...
HAVE UPDATED TO REMOVE WIND ADVISORY FOR THE MIDCOAST REGION.
STRONGEST WINDS HAVE SHIFTED EAST OF THE REGION. MORE SHOWERS WILL
DEVELOP TODAY...HOWEVER NOT WITH THE INTENSITY OF LAST NIGHT.

PREV DISC...
LOW PRESSURE MOVING EAST ACROSS THE ST LAWRENCE RIVER
VALLEY WILL BRING A WARM AND STRONG SOUTHERLY FLOW ACROSS THE
REGION THIS MORNING WITH RECORD WARM TEMPS. MOST OF THE
THUNDERSTORMS AND HEAVY RAINS WILL COME TO AN END BY 12Z AS A DRY
SLOT MOVES ACROSS THE AREA. THIS IS WELL DEPICTED BY THE TRENDS
OFF THE HRRR MODEL. THE LOW LEVEL JET CURRENTLY MOVING ACROSS THE
FORECAST AREA HAS MIXED DOWN TO THE SURFACE...SO THE GUSTY SURFACE
WINDS WILL CONTINUE OVER MUCH OF THE AREA THROUGH MUCH OF THE DAY
UNTIL THE TRAILING COLD FRONT SWINGS ACROSS THE AREA LATER IN THE
DAY. THE WIND ADVISORY WILL REMAIN IN PLACE ALONG THE MIDCOAST
AREA. RECORD WARM TEMPS WILL START OUT THE DAY BUT WILL COOL SOME
IN THE AFTERNOON AS COLD AIR BEGINS TO FILTER IN BEHIND THE COLD
FRONT.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/...
TONIGHT THE UPPER TROF AND ITS CYCLONIC FLOW WILL BRING PLENTY OF
CLOUDS AND SCATTERED SNOW SHOWERS..MAINLY IN THE MOUNTAINS. VERY
LITTLE IF ANY ACCUMULATIONS EXPECTED. COLDER AIR WILL FILTER IN
TONIGHT AND FRI RETURNING TEMPS TO SLIGHTLY BELOW NORMAL LEVELS.
FRIDAY DRIER AIR MOVES IN ON DOWNSLOPING NORTHWEST WINDS SO A FAIR
AMOUNT OF SUN IS EXPECTED.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
NORTHWEST WINDS WILL BRING COLDER AIR INTO THE REGION FRIDAY
NIGHT AS A RIDGE OF HIGH PRESSURE BUILDS INTO THE AREA. THE RIDGE
WILL MOVE OFF THE COAST SATURDAY AS ANOTHER FRONT APPROACHES THE
REGION FROM THE NORTHWEST. THE FRONT WILL STALL ACROSS THE AREA
SUNDAY AND THEN MOVE NORTH EARLY MONDAY AS A WARM FRONT AS LOW
PRESSURE MOVES NORTH OF THE AREA. THE LOW WILL DRAG A COLD FRONT
ACROSS THE AREA LATE MONDAY USHERING A RETURN MORE SEASONABLE
TEMPERATURES. ANOTHER FRONT WILL APPROACH THE REGION WEDNESDAY
WITH LOW PRESSURE ALONG THE FRONT LATE IN THE WEEK.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
SHORT TERM...IFR WITH LCL LIFR THROUGH EARLY THIS MORNING. SCT
TSTMS EARLY THIS MORNING OVER EASTERN AND SOUTHERN AREAS AHEAD
OF A COLD FRONT. CONDS IMPROVING TO MVFR TODAY. SFC WINDS WILL
GUST OVR 40 KT UNTIL 15Z THU BEFORE GRADUALLY DIMINISHING. LLWS
WILL PERSIST INTO THE MORNING.

LONG TERM...VFR CONDITIONS FRIDAY NIGHT THROUGH SUNDAY. MVFR
CONDITIONS LATE SUNDAY AND MONDAY.

&&

.MARINE...
SHORT TERM...SOUTHERLY GALES TODAY AS A STRONG COLD FRONT CROSSES
THE WATERS LATER IN THE DAY. WINDS WILL BECOME WEST TONIGHT AND
SLOWLY DIMINISH.

LONG TERM...WINDS AND SEAS MAY DROP BELOW SCA CONDITIONS

PERIOD.

&&

.HYDROLOGY...
RAINFALL AMOUNTS OF 1 TO 3 INCHES THROUGH THIS MORNING.
LOCALIZED HIGHER AMOUNTS ARE POSSIBLE ON THE EAST-SOUTHEAST
FACING SLOPES OF THE WHITES AND MAINE FOOTHILLS. THIS MAY POSE
SOME FLOODING PROBLEMS FOR POOR DRAINAGE AREAS AS WELL AS
