.SYNOPSIS...
HIGH PRESSURE WILL GENERALLY REMAIN IN CONTROL OF THE
WEATHER ACROSS THE REGION THROUGH THE REST OF THE WEEKEND AND AT
LEAST THE FIRST HALF OF NEXT WEEK...WITH AN EXTENDED PERIOD OF
QUIET WEATHER EXPECTED. TEMPERATURES WILL REMAIN WELL ABOVE
SEASONAL NORMS THROUGH THE PERIOD...WITH GRADUALLY INCREASING
HUMIDITY. TUESDAY AND WEDNESDAY COULD BE QUITE HOT FOR EARLY
SEPTEMBER. A COLD FRONT COULD COOL US DOWN BY LATE WEEK.
SUBSTANTIAL RAINFALL IS NOT IN THE FORECAST THROUGH LATE NEXT
WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
A WEAK SHORT WAVE TROUGH WILL CROSS NORTHERN NEW ENGLAND TONIGHT
AND THIS WILL PROBABLY JUST BE ACCOMPANIED BY A PERIOD OF MID AND
HIGH LEVEL CLOUDS. THERE COULD BE A BRIEF LIGHT SHOWER IN THE
MOUNTAINS LATE. OTHERWISE...VALLEY FOG IS ONCE AGAIN EXPECTED IN
THE NORMALLY VULNERABLE AREAS.

&&

.SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/...
ONE WEAK SHORT WAVE TROUGH WILL PASS THROUGH THE REGION BY MIDDAY
SUNDAY. OTHER THAN A PERIOD OF BKN CLOUDS AND A FEW SPOT
SHOWERS ON SUNDAY...WE SHOULD HAVE PLENTY OF SUN AND TEMPERATURES
SHOULD GET WELL INTO THE 80S. ANOTHER SHORT WAVE TROUGH WILL CROSS
THE AREA SUNDAY NIGHT...AND AT THIS TIME IT LOOKS LIKE IT WILL
COME THROUGH WITH VERY LITTLE FANFARE.

&&

.LONG TERM /MONDAY THROUGH SATURDAY/...
STRONG UPPER LEVEL RIDGING OVER THE GREAT LAKES WILL START TO
SLOWLY MIGRATE EASTWARD ON MONDAY. THIS WILL ALLOW TEMPERATURES TO
CLIMB ABOVE NORMAL AS WELL. A WEAK DISTURBANCE WILL MOVE THROUGH
MONDAY NIGHT...BUT WILL PRODUCE LITTLE IN THE WAY OF WEATHER.
TEMPERATURES UNDER THE RIDGE ON TUESDAY WILL BE 10F TO 15F DEGREES
WARMER THAN NORMAL WITH MOST LOCATIONS SEEING TEMPERATURES WELL
INTO THE 80S AND LOWER 90S. HIGH PRESSURE REMAINS IN PLACE THROUGH
THURSDAY WHEN A WEAK BACK DOOR COLD FRONT WILL TRY TO DROP
SOUTHWARD ACROSS THE AREA. DRY CONDITIONS REMAIN IN PLACE FOR THE
REMAINDER OF THE FORECAST PERIOD.
