DISCUSSION
KEY MESSAGE 1 DESCRIPTION...
ANOTHER LOW PRESSURE SYSTEM DIVES SOUTHWARD INTO NEW ENGLAND
THROUGH THE AFTERNOON TODAY AND TONIGHT. THIS ONE WON'T BE AS
ORGANIZED OR AS STRONG AS THE ONE YESTERDAY, BUT IT BRINGS WITH
IT WIDESPREAD SHOWERS AND THUNDERSTORMS. THESE CONTINUE TO
INCREASE IN COVERAGE THROUGH THE AFTERNOON HOURS AS COLDER AIR
MOVES IN ALOFT. THIS COLDER AIR ALOFT ALSO INCREASES THE CHANCE
FOR HEAVIER SHOWERS AND STORMS TO CONTAIN SMALL HAIL, AND BRING
SOME GUSTY WINDS AT TIMES.
THE COVERAGE OF THE SHOWERS AND STORMS DECREASES OVERNIGHT, BUT
ARE LIKELY TO CONTINUE THROUGH THE OVERNIGHT HOURS NEAR THE LOW
PRESSURE CENTER. THIS CENTER IS EXPECTED TO PIVOT THROUGH
SOUTHERN MAINE, AND THEN SLIP OFFSHORE BY THE MORNING HOURS ON
MONDAY.
KEY MESSAGE 2 DESCRIPTION...
AS THE LOW MOVES AWAY, A PERIOD OF RELATIVELY DRIER CONDITIONS
MOVES IN FOR MONDAY. HOWEVER, WITH COLD AIR ALOFT FOLLOWING THE
LOW, ISOLATED POP UP SHOWERS WILL BE POSSIBLE AGAIN BY THE
AFTERNOON HOURS ON MONDAY. COOL CANADIAN AIR FOLLOWS THE LOW,
YIELDING HIGHS IN THE 60S ACROSS MOST OF NORTHERN NEW ENGLAND.
EVEN WHERE THE MOST SUNSHINE HOLDS ON THROUGH THE DAY, MID 60S
LOOK LIKE THE HIGH END FOR TEMPS TOMORROW.
SKIES CLEAR TOMORROW NIGHT AS DRIER AIR MOVES IN. THIS BRINGS
ANOTHER SEASONABLY COOL NIGHT, WITH LOWS DROPPING INTO THE UPPER
30S TO LOW 40S. A SMALL AREA OF HIGH PRESSURE PASSES THROUGH
EARLY IN THE OVERNIGHT. WITH ALL THE RECENT RAINFALL, SOME
PATCHY FOG WILL BE POSSIBLE TOMORROW NIGHT THROUGH THE VALLEYS.
CLOUDS THEN INCREASE TOWARD MORNING AS A WEAK TROUGH PIVOTS IN
FROM THE NORTH.
KEY MESSAGE 3 DESCRIPTION...
THE UPPER LEVEL TROUGHING WILL LESSEN TUESDAY AS IT GRADUALLY GETS
REPLACED BY SHORT WAVE RIDGING BY LATER IN THE DAY. THIS SHOULD
LESSEN COVERAGE OF DIURNAL SHOWERS AND ALLOW FOR WARMER WEATHER.
HOWEVER, LINGERING COLD AIR ALOFT WORKING IN TANDEM WITH WEAK
LOW LEVEL CONVERGENCE SHOULD ALLOW FOR WIDELY SCATTERED SHOWERS
AND PERHAPS ISOLATED THUNDERSTORMS DURING THE AFTERNOON,
ESPECIALLY ON THE COASTAL PLAIN.
OVERHEAD RIDGING WITH FURTHER STRENGTHEN ON WEDNESDAY AND
THURSDAY WITH DRY WEATHER AND HIGHS IN THE 70S ON WEDNESDAY AND
80S ON THURSDAY.
CHANCES FOR SHOWERS INCREASE SOME LATE FRIDAY AS A COLD FRONT
MAY BEGIN TO SAG SOUTHWARD OUT OF CANADA. HOWEVER, MAINLY DRY
WEATHER IS EXPECTED WITH SUMMER-LIKE HIGHS WELL INTO THE 80S.
THE THREAT MAY CONTINUE INTO SUNDAY DEPENDING ON FRONTAL
POSITION.
AVIATION /18Z SUNDAY THROUGH FRIDAY/
CEILINGS LOWER TO MVFR AT MOST TERMINALS THROUGH THE EVENING AS
SHOWERS MOVE THROUGH DURING THE AFTERNOON AND EVENING.
THUNDERSTORMS ARE ALSO POSSIBLE AT ALL TERMINALS LATE THIS
AFTERNOON AND EARLY EVENING. CEILINGS LIKELY FALL TO IFR AT MOST
TERMINALS OVERNIGHT, AND THEN MVFR TO VFR RETURNS WITH CLEARING
SKIES MONDAY MORNING. SCATTERED SHOWERS ARE POSSIBLE TOMORROW
AFTERNOON. VFR PREVAILS TOMORROW NIGHT, BUT SOME VALLEY FOG IS
POSSIBLE.
OUTLOOK:
TUESDAY: VFR WITH ISOLATED SHOWERS POSSIBLE ON THE COASTAL PLAIN
IN THE AFTERNOON. LIGHT NORTH WINDS BECOMING SOUTHERLY ON THE
COASTAL PLAIN DURING THE AFTERNOON.
TUESDAY NIGHT: VFR EXPECTED.
WEDNESDAY/WEDNESDAY NIGHT: VFR WITH LIGHT WINDS.
THURSDAY/FRIDAY: HIGH PRESSURE IS FAVORED WITH VFR CONDITIONS.
MARINE
CONDITIONS REMAIN BELOW SCA LEVELS THROUGH MONDAY NIGHT. A WEAK

FAIR WEATHER TUE-FRI WITH WINDS AND SEAS REMAINING BELOW SCA
THRESHOLDS.
