AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAY ME

.SYNOPSIS...
WEAK TROUGH SWINGS THROUGH NEW HAMPSHIRE AND MAINE THIS EVENING.
LOW PRESSURE WILL FORM NEAR THE VIRGINIA COASTLINE FRIDAY...BEFORE
REACHING COASTAL MAINE SATURDAY MORNING. AN UPPER LEVEL LOW
PRESSURE SYSTEM WILL KEEP THINGS UNSETTLED INTO NEXT WEEK.
&&
.NEAR TERM /THROUGH TONIGHT/...
CONVECTION CONTINUES TO FIRE OVER AND WEST OF OUR FORECAST AREA
THIS AFTERNOON IN RESPONSE TO WEAK SURFACE TROUGH HEADING EAST.
COLD POOL ALOFT...WITH ASSOCIATED LOW LEVEL THERMAL ADVECTION WILL
CONTINUE TO DESTABILIZE THE ATMOSPHERE FOR THE NEXT FEW HOURS.
BEST CHANCE FOR ISOLATED STRONG/SEVERE THUNDERSTORMS WILL BE OVER
SOUTHERN NEW HAMPSHIRE. SURFACE READINGS IN THE AREA ARE NOW NEAR
80 DEG WITH DEW POINTS CLIMBING INTO THE MID 60S. THREAT WOULD BE
FOR DAMAGING WINDS OR HAIL. HAVE KEPT ENHANCED WORDING IN THE
SOUTHERN NEW HAMPSHIRE COUNTIES.
PRECIPITATION SHOULD ROLL THROUGH THE REGION AND BEGIN TO TAPER
OFF BETWEEN 02-03Z. THEREAFTER...LOW CLOUDS AND FOG MAY QUICKLY
DEVELOP THIS EVENING. HAVE ADDED FOG TO THE FORECAST.
BLEND OF MAV/MET MOS USED FOR OVERNIGHT MINS.
&&
.SHORT TERM /FRIDAY/...
WILL WE ACTUALLY HIT 80F TOMORROW? IF SO...THIS WOULD BE THE FIRST
TIME (IN PORTLAND) SINCE MAY 26TH. WILL TREND SLIGHTLY BELOW
MACHINE GUIDANCE HOWEVER WITH MARITIME CONDITIONS STILL IN PLACE.
RAIN FROM APPROACHING COASTAL LOW WILL APPROACH THE REGION LATE IN
THE 2ND PERIOD...HOWEVER...EXPECT MAINLY DRY CONDITIONS DURING THE
DAY FRIDAY.
&&
.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...
THE H5 LOW WILL CONTINUE TO INFLUENCE OUR WEATHER FOR SEVERAL MORE
DAYS. THE 12Z MODEL SOLUTIONS INDICATE THAT THE HEAVIER RAINFALL
ASSOCIATED WITH THE SURFACE LOW PRESSURE AREA EJECTING TO THE
NORTHEAST SHOULD ARRIVE SATURDAY MORNING WITH QPF AMOUNTS OF A
HALF INCH TO AN INCH POSSIBLE. IMPROVING WEATHER SHOULD THEN
FOLLOW FOR THE SECOND HALF OF THE WEEKEND WITH PARTLY SUNNY SKIES
SUNDAY SOUTH OF THE MOUNTAINS. BEYOND THAT WOULD EXPECT SOMEWHAT
UNSETTLED WEATHER TO CONTINUE WITH SCATTERED SHOWERS AT TIMES AND
SOME PEAKS OF SUN NOW AND THEN. BEST CHANCE FOR A SUNNY DAY
APPEARS TO BE ON WEDNESDAY AS AN H5 RIDGE BUILDS OVER NEW
ENGLAND...BUT CONFIDENCE IS LOW OF THE TIMING OF THESE DETAILS
6 TO 7 DAYS OUT WITH AN ATYPICAL SUMMER WEATHER PATTERN. OVERNIGHT
LOW TEMPERATURES ARE EXPECTED TO AVERAGE NEAR NORMAL TO SLIGHTLY
ABOVE NORMAL WHILE DAYTIME HIGH TEMPERATURES SHOULD AVERAGE NEAR
NORMAL TO SLIGHTLY BELOW NORMAL.
&&
.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
SHORT TERM...CONDITIONS DETEORATE THIS EVENING INTO IFR CONDITIONS
IN SOUPY MARITIME AIRMASS. CEILINGS DROP TO LIFR THIS
EVENING...WITH CLOUDS/FOG GRADUALLY LIFTING ON FRIDAY.

SHORT TERM...SEAS ARE MARGINAL TONIGHT...BUT HAVE RAISED SCAS FOR
SEAS OVER THE OPEN WATERS. DID DROP SEAS BELOW WNA GUIDANCE BY A
FOOT OR TWO WHICH STILL LEAVES OUR WATERS IN THE 3-5 FOOT RANGE.
