WEATHER SUMMARY FOR MAINE AND NEW HAMPSHIRE
NATIONAL WEATHER SERVICE GRAY MAINE
315 AM EDT WED JUL 23 2014

HIGH PRESSURE TO OUR SOUTH WAS PUMPING VERY WARM AND HUMID AIR INTO
NEW ENGLAND TUESDAY AND TUESDAY NIGHT. EARLY THIS MORNING
TEMPERATURES WERE STILL IN THE MILD 60S NORTH AND MID 60S TO MID 70S
SOUTH. DEW POINT TEMPERATURES, A MEASURE OF HOW HUMID THE AIR IS,
WERE IN THE MUGGY 60S.

THE VERY WARM AND HUMID AIR WILL STAY WITH US THROUGH WEDNESDAY AS A
COLD FRONT BEARS DOWN FROM THE NORTHWEST. AHEAD OF THE FRONT ENOUGH
SUNSHINE SHOULD PUSH TEMPERATURES INTO THE 80S...WITH LOWER 90S
POSSIBLE ACROSS SOUTHERN NEW HAMPSHIRE AND SOUTHERN AND CENTRAL
MAINE. ALONG THE COAST...WINDS MAY TURN ONSHORE KEEPING HIGHS A
LITTLE COOLER.

AS THE FRONT CLASHES WITH THE VERY WARM AND MUGGY AIR IT WILL CAUSE
SHOWERS AND THUNDERSTORMS TO DEVELOP. SOME OF THE THUNDERSTORMS
COULD BECOME SEVERE THIS AFTERNOON AND EVENING WITH DAMAGING WIND
GUSTS AND MAYBE EVEN SOME LARGE HAIL. FREQUENT LIGHTNING STRIKES AND
HEAVY DOWNPOURS ARE ALSO POSSIBLE WITH ANY THUNDERSTORMS.

THE FRONT SLOWLY WORKS ITS WAY TO THE COAST WEDNESDAY NIGHT AS THE
SHOWERS AND THUNDERSTORMS TAPER OFF. THE FRONT WILL LIE JUST
OFFSHORE ON THURSDAY AS WEAK LOW PRESSURE TRACKS TO THE NORTHEAST
ALONG THE BOUNDARY. COOLER AND LESS HUMID AIR WILL FILTER IN FROM
CANADA ON THURSDAY...BUT THE PROXIMITY OF THE FRONT AND LOW PRESSURE
SYSTEM WILL PROBABLY KEEP CLOUDS AROUND MOST OF THE DAY...WITH MAYBE
A FEW SHOWERS POSSIBLE ALONG THE COAST.

THE FRONT FINALLY MOVES WELL OUT TO SEA AS HIGH PRESSURE MOVES IN
FROM THE WEST THURSDAY NIGHT. THIS WILL LET THE COOLER AND LESS
HUMID AIR FULLY OVERTAKE THE REGION. BY FRIDAY MORNING LOW
TEMPERATURES WILL RANGE FROM THE 40S NORTH TO THE 50S SOUTH.

THE HIGH PRESSURE SYSTEM WORKS ITS WAY TO THE COAST FRIDAY NIGHT
THEN OUT TO SEA ON SATURDAY...STAYING WELL TO OUR SOUTH. THIS WILL
GRADUALLY BRING IN WARMER AIR ON SATURDAY BUT OUR WEATHER SHOULD
STAY DRY.

LOW PRESSURE APPROACHES FROM THE GREAT LAKES REGION ALONG WITH A
WARM FRONT FROM THE SOUTH. THIS WILL BRING UNSETTLED WEATHER WITH A
CHANCE OF SHOWERS AND THUNDERSTORMS FOR A PROLONGED PERIOD OF TIME
...FROM SATURDAY NIGHT THROUGH TUESDAY.
