000 FXUS61 KGYX 021542 AFDGYX AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GRAY ME 1142 AM EDT THU JUL 2 2015 .SYNOPSIS... HIGH PRESSURE BUILDS IN TODAY AND REMAINS IN PLACE THROUGH LATE SATURDAY NIGHT...PROVIDING DRY AND MAINLY SUNNY WEATHER RIGHT THROUGH THE FOURTH OF JULY. A WEAK TROUGH OF LOW PRESSURE MOVES TO OUR NORTH ON SUNDAY. HIGH PRESSURE THEN BUILDS IN THROUGH MIDWEEK. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... 1140 AM...JUST A QUICK UPDATE TO BRING T/TD/SKY/WIND INTO LINE WITH CURRENT OBS...ALTHOUGH OVERALL FORECAST STILL HOLDS FOR A MAINLY SUNNY AND SEASONABLY MILD AFTERNOON. 7AM UPDATE... HIGH THIN CIRRUS CLOUDS HAVE BEGUN MOVING INTO THE AREA. WHILE THESE ARE NOT VERY OPAQUE AND THE SUN IS SHINING BRIGHTLY THROUGH THEM... IT IS ENOUGH TO UPDATE THE SKY COVER IN THE FORECAST TO INDICATE A BIT MORE CLOUDS THIS MORNING. OTHERWISE NO SIGNIFICANT CHANGES WERE MADE. ORIGINAL DISCUSSION... AS LOW PRESSURE DEPARTS... HIGH PRESSURE WILL BUILD IN FROM THE WEST TODAY. IT SHOULD BE A MOSTLY SUNNY DAY... ALTHOUGH SOME AFTERNOON CUMULUS ARE POSSIBLE. TEMPERATURES WARM INTO THE 70S TO NEAR 80 DEGREES IN SOUTHERN NEW HAMPSHIRE. LIGHT SOUTHWEST WINDS WILL ALLOW A SEABREEZE TO APPROACH THE COAST AND PROVIDE THE MOST IMPACT TO THE MIDCOAST REGION OF MAINE. ALTHOUGH RIP CURRENTS HAVE BEEN NOTED THE PAST FEW DAYS AT SOME AREA BEACHES... FORECAST CONDITIONS TODAY DO NOT APPEAR TO FAVOR AN ENHANCED CHANCE OF RIP CURRENTS. WINDS OVER THE WATER TODAY WILL BE VERY LIGHT OUT OF THE SOUTHWEST (INSTEAD OF ONSHORE) WITH WAVE HEIGHTS DECREASING. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/... CLEAR AND CALM CONDITIONS EXPECTED OVER THE WESTERN PART OF THE FORECAST AREA TONIGHT... CLOSER TO THE CENTER OF HIGH PRESSURE. THIS WILL ALLOW GOOD RADIATIONAL COOLING CONDITIONS. DRY AIR IN PLACE WILL ALLOW TEMPERATURES TO FALL INTO THE 40S. COASTAL MAINE AND THE SOUTHEAST HALF OF NEW HAMPSHIRE WILL BOTTOM OUT IN THE LOW TO MID 50S. SHOULD BE A DEGREE OR TWO WARMER ON FRIDAY WITH HIGH PRESSURE STILL IN CONTROL. A SEABREEZE IS POSSIBLE ALONG THE COAST LATER IN THE DAY. && .LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/... THE NEXT TWO TO SEVEN DAYS LOOK MOSTLY PRECIPITATION FREE WITH TEMPERATURES RIGHT AROUND OR SLIGHTLY ABOVE NORMAL. ON SATURDAY HIGH PRESSURE REMAINS CENTERED OFFSHORE BUT INFLUENCES THE WEATHER OVER NORTHERN NEW ENGLAND BY SUPPLYING SUNNY SKIES AND A SEA BREEZE IN THE AFTERNOON. TEMPERATURES WILL BE SLIGHTLY COOLER ALONG THE COAST DUE TO THIS FEATURE. BY THAT NIGHT A TROUGH OF LOW PRESSURE WILL HAVE ENTERED THE NORTHERN COUNTIES AS LOW PRESSURE TRAVELS THROUGH EASTERN CANADA. THE TROUGH SHARPENS ON SUNDAY AND SOME RAIN SHOWERS MAY DEVELOP ESPECIALLY IN THE HEAT OF THE AFTERNOON. STILL THE SHOWERS WILL HAVE MINIMAL IMPACT ON AS FAR AS RAINFALL AMOUNTS GO AND SHOULD EXIT THE AREA BY THE EVENING. HIGH PRESSURE BUILDS IN FROM THE WEST MONDAY AND REMAINS OVERHEAD TUESDAY BRINGING SUNNY SKIES AND LIGHT WINDS. WE WILL SEE TEMPERATURES IN THE MID TO UPPER 80S AREA WIDE. WEAK TROUGHING STEERS ANOTHER BOUNDARY OUR WAY IN THE THURSDAY TIME FRAME... BUT IT REMAINS TO BE SEEN WHETHER THIS FEATURE WILL WASH OUT BEFORE IT REACHES US. && .AVIATION /16Z THURSDAY THROUGH MONDAY/... SHORT TERM...HIGH PRESSURE BRINGS A CLEAR SKY AND LIGHT WINDS FOR THE NEXT FEW DAYS. LONG TERM...POSSIBLE MVFR CEILINGS SATURDAY NIGHT UNTIL SUNDAY NIGHT IN RAIN SHOWERS AS A FRONT MOVES ACROSS THE REGION. && .MARINE... SHORT TERM...HIGH PRESSURE BUILDS EAST INTO NEW ENGLAND AND THE GULF OF MAINE BRINGING LIGHT WINDS AND DECREASING WAVE HEIGHTS. LONG TERM...NO PROBLEMS NOTED ON THE WATERS. HIGH PRESSURE WILL CONTROL THE WATERS FOR MOST OF THE NEXT 7 DAYS.
