Area forecast discussion, Aug 6, 2:07 PM EST, 2 hours 19 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAY ME
307 PM EDT WED AUG 6 2014

.SYNOPSIS...
A COLD FRONT WILL EXIT THE REGION TO THE SOUTHEAST THIS EVENING.
AN UPPER TROUGH WILL PRODUCE SCATTERED DAYTIME SHOWERS AND
ISOLATED THUNDERSTORMS THURSDAY AND FRIDAY. A LARGE RIDGE OF HIGH
PRESSURE AND DRIER AIR WILL ARRIVE IN TIME FOR THE UPCOMING
WEEKEND. THE HIGHS SHIFTS OFFSHORE EARLY NEXT WEEK...AND WILL
PRODUCE SOUTHWEST WINDS WHICH WILL ALLOW FOR A WARM UP.

&&

.NEAR TERM /TONIGHT/...
MAIN BAND OF SHRA AND TSRA WILL MOVE OFFSHORE THRU LATE
AFTERNOON. THERE ARE SCATTERED SHRA...WITH PERHAPS A RUMBLE OF
THUNDER BEHIND THIS LINE. THESE MAY LINGER IN THE MOUNTAINS AND
FOOTHILLS THRU ABOUT 00Z...BUT DOWNSLOPE WILL WEAKEN THEM AS THE
GET CLOSER TO THE COAST.

BEHIND THE FRONT...LOOK FOR SKIES TO CLEAR...WITH LOWER DEW POINTS
AND COOLER MINS. LOWS WILL GENERALLY BE IN THE 50S INLAND...TO
AROUND 60 ON THE COAST.

&&

.SHORT TERM /THURSDAY THROUGH THURSDAY NIGHT/...
LIGHT NW FLOW AT THE SURFACE WILL PERSIST ON THURSDAY...BUT 500 MB
CLOSED LOW CROSSES RIGHT OVER THE FORECAST AREA DURING DAYTIME
HEATING. THE INSTABILITY GENERATED WILL PRODUCE A FAIR AMOUNT OF
CLOUDS...AS WELL AS SHRA AND A FEW TSRA...GENERALLY FROM LATE
MORNING THRU AROUND SUNSET. COLD ENOUGH THAT ANY SUSTAINED
UPDRAFTS COULD PRODUCE SOME SMALL HAIL...BUT THESE WILL BE
LIMITED. ALL THE CLOUDS WILL LIMIT HIGHS IN THE NORTHERN ZONES TO
THE LOW TO MID 70S...WITH SOUTHERN AREAS GENERALLY IN THE MID
70S TO AROUND 80.

ANY SHRA WILL DIMINISH WITH THE LOSS OF HEATING THURSDAY
NIGHT...AND SKIES SHOULD CLEAR OUT SOME...WITH LOWS DROPPING
BACK INTO THE 50S MOST EVERYWHERE.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
HIGH PRESSURE OVER THE GREAT LAKES AND LOW PRESSURE OVER THE
CANADIAN MARITIMES KEEPS A NORTHERLY FLOW OVER THE AREA... WITH
GENERALLY DRY AND COOL CONDITIONS. HOWEVER... UPPER LOW OVER THE
MARITIMES AND AN IMPULSE ROTATING AROUND IT WILL CONTRIBUTE TO A
CHANCE OF SHOWERS FRIDAY AFTERNOON PRIMARILY ACROSS THE EASTERN
HALF OF THE AREA. INSTABILITY IS NOT ALL THAT IMPRESSIVE SO
THUNDERSTORMS ARE NOT VERY LIKELY.

UPPER LOW MOVES EAST ON SATURDAY... WITH THE SURFACE HIGH DRIFTING
EAST INTO THE AREA AS WELL. EXPECT DRY CONDITIONS WITH
TEMPERATURES WARMING A BIT... INTO THE LOW 80S.

AS SURFACE HIGH SHIFTS OFFSHORE ON SUNDAY... A SOUTHERLY FLOW WILL
BEGIN TO TRANSPORT MORE WARMTH AND MOISTURE INTO THE AREA. SO FOR
SUNDAY... MONDAY... AND TUESDAY... EXPECT GRADUALLY INCREASING
TEMPERATURES AND DEW POINTS AS WELL AS INCREASING CHANCES FOR
SHOWERS IN THE AFTERNOONS... ESPECIALLY IN THE MOUNTAINS.

BY TUESDAY... UPPER TROUGH OVER CANADA MOVES FAR ENOUGH EAST TO
DRAG A COLD FRONT CLOSER TO THE AREA. EXPECT INCREASED CHANCES OF
SHOWERS TUESDAY THROUGH THURSDAY AS THIS FRONT MAKES IT THROUGH
THE AREA SOMETIME IN THAT TIME FRAME.

&&

.AVIATION /19Z WEDNESDAY THROUGH MONDAY/...
SHORT TERM...ANY SHRA/TSRA IN MAINE WILL DIMINISH BY SUNSET...WITH
VALLEY FOG DEVELOPING AFTER MIDNIGHT. EXPECT MAINLY VFR ON
THURSDAY...WITH SCATTERED SHRA AND A FEW TSRA. THURSDAY
NIGHT...WITH THE EXCEPTION OF VALLEY FOG...EXPECT VFR.

LONG TERM...EXPECT A PERIOD OF PROLONGED VFR CONDITIONS THROUGH
EARLY NEXT WEEK... OUTSIDE OF THE USUAL VALLEY FOG AT NIGHT.

&&

.MARINE...
SHORT TERM...WINDS/SEAS REMAIN BELOW SCA LEVELS. SWELL WILL PUSH
SEAS UP TO NEAR 4 FT TONIGHT INTO THURSDAY.

LONG TERM...WITH HIGH PRESSURE MOVING OVER THE WATERS THIS
WEEKEND... EXPECT THE WIND FLOW TO BE DOMINATED BY SEA BREEZES.
WAVE HEIGHTS SHOULD REMAIN LOW AS WELL.

&&

.GYX WATCHES/WARNINGS/ADVISORIES...
ME...NONE.
NH...NONE.
MARINE...NONE.
