Area forecast discussion, Jul 19, 2:37 PM EST, 44 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAY ME 337 PM EDT SUN JUL 19 2015 .SYNOPSIS... A COLD FRONT WILL PUSH OFFSHORE TONIGHT WITH SHOWERS AND THUNDERSTORMS AHEAD OF IT. HIGH PRESSURE WILL BUILD IN FROM THE WEST ON MONDAY. ANOTHER COLD FRONT WILL APPROACH FROM THE WEST MONDAY NIGHT AND WILL CROSS THE AREA ON TUESDAY WITH ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS. HIGH PRESSURE WILL BUILD IN FROM THE WEST TUESDAY NIGHT AND WEDNESDAY. ANOTHER COLD FRONT WILL DROP SOUTH FROM CANADA ON THURSDAY. HIGH PRESSURE WILL BUILD IN FROM THE WEST FRIDAY AND WILL SHIFT OFFSHORE ON SATURDAY. && .NEAR TERM /TONIGHT/... THUNDERSTORMS HAVE BEGUN TO FORM WITHIN THE WARM AND HUMID AIR MASS OVER THE SOUTHERN HALF OF NEW HAMPSHIRE AND FAR SOUTHWEST MAINE. GIVEN THE HIGH INSTABILITY AND INCREASING SHEAR... SOME OF THE STORMS WILL BE CAPABLE OF PRODUCING LARGE HAIL AND DAMAGING WINDS. AS THE STORMS RIDE ALONG A WARM FRONTAL BOUNDARY THE LOW LEVEL TURNING OF THE WINDS WILL ADD A THREAT FOR AN ISOLATED TORNADO. SEVERE THUNDERSTORM WATCH HAS BEEN ISSUED UNTIL 11 PM FOR NEW HAMPSHIRE AND YORK COUNTY IN MAINE. EXPECT STORMS TO EVENTUALLY FORM INTO A LARGER COMPLEX OF STORMS AND MOVE ACROSS THE AREA OVERNIGHT. COULD SEE MUCH OF THE ACTIVITY MOVE EAST BY MIDNIGHT. TEMPERATURES WILL BE WARM OVERNIGHT AS LOW LEVEL HUMIDITY REMAINS HIGH. SOME LOCATIONS MAY NOT FALL BELOW 70 DEGREES. && .SHORT TERM /MONDAY AND MONDAY NIGHT/... COLD FRONT WILL HAVE MOVED THROUGH THE AREA BEFORE DAYBREAK... BRINGING ANY LINGERING SHOWERS OR STORMS TO AN END. LOW LEVEL MOISTURE WILL BE A LITTLE SLOW IN ERODING OVER COASTAL MAINE BUT IT WILL BE GENERALLY A DRIER DAY WITH WARM TEMPERATURES ONCE AGAIN. WITH DRIER AIR IN PLACE EXPECT A COOLER NIGHT MONDAY NIGHT WITH TEMPERATURES FALLING INTO THE 50S AND 60S. && .LONG TERM /TUESDAY THROUGH SUNDAY/... FOR THE OUTLOOK PERIOD GENERALLY A MEAN LONG WAVE TROUGH POSITION REMAINS ACROSS THE NORTHEAST SO A LACK OF HEAT AND HUMIDITY SHOULD BE HIGHLIGHTED. A SHORT WAVE CLIPPER SYSTEM WITH AN ASSOCIATED SURFACE COLD FRONT WILL ROTATE AROUND THE BASE OF THE MEAN TROUGH IN THE EAST AND MOVE ACROSS THE AREA TUESDAY AND TUESDAY NIGHT. THIS WILL CAUSE SHOWERS AND THUNDERSTORMS ACROSS THE AREA. THEN FOR THE REST OF THE WEEK THE UPPER TROUGH OF LOW PRESSURE SETTLES OVER NEW ENGLAND WITH A CYCLONIC FLOW ALOFT AND DRY NORTHWEST FLOW IN THE LOWER LEVELS. THIS WILL MEAN COMFORTABLE TEMPERATURES AND LOW HUMIDITIES TO PERSIST WITH DRY CONDITIONS. DUE TO THE COOL AIR MASS ALOFT AN ISOLATED AFTERNOON DIURNAL SHOWER OR THUNDERSTORM CAN'T BE RULED OUT...ESPECIALLY IN THE MOUNTAINS. TEMPERATURES WILL BE PLEASANTLY COOL WITH DAYTIME HIGHS GENERALLY IN THE 70S TO AROUND 80 AND OVERNIGHT LOWS IN THE 50S TO LOWER 60S. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... SHORT TERM... VFR CONDITIONS EXPECTED TODAY BUT SCATTERED THUNDERSTORMS WILL BE DEVELOPING THIS EVENING. MUCH OF THE THUNDERSTORM ACTIVITY WILL MOVE EAST OF THE AREA BY MIDNIGHT. COULD SEE SOME FOG DEVELOPING OVERNIGHT ESPECIALLY IN AREAS WHICH GET A GOOD SOAKING DURING THE EVENING. LONG TERM...MVFR TO IFR POSSIBLE IN SHOWERS AND THUNDERSTORMS ON TUESDAY INTO TUESDAY EVENING FOLLOWED BY MAINLY VFR CONDITIONS THE REST OF THE WEEK. && .MARINE... SHORT TERM... WEAK PRESSURE GRADIENT LEADS TO LIGHT WINDS AND FAIRLY CALM SEAS. LONG TERM...SUB-SCA CONDITIONS ARE CURRENTLY EXPECTED TUESDAY THROUGH THE REST OF THE WEEK. && .GYX WATCHES/WARNINGS/ADVISORIES...
