DISCUSSION
KEY MESSAGE 1 DESCRIPTION...
CLEAR SKIES RETURN TONIGHT AS TODAY'S STORM SYSTEM DEPARTS.
WINDS ALSO EASE THIS EVENING, ALLOWING FOR A PERIOD OF
RADIATIONAL COOLING TONIGHT. GIVEN THE COOL START, TEMPERATURES
ARE EXPECTED TO FALL TO NEAR FREEZING ACROSS THE NORTH BEFORE
THE NEXT BATCH OF CLOUDS ARRIVES AHEAD OF THE NEXT SYSTEM LATE
TONIGHT. FOR THIS REASON, A FROST ADVISORY HAS BEEN ISSUED.
DOWNWIND OF THE MOUNTAINS AND ALONG THE COASTAL PLAIN, A LIGHT
WEST BREEZE LIKELY KEEPS TEMPS FROM REACHING THEIR FULL COOLING
POTENTIAL. THE EXCEPTION WILL BE DOWNWIND OF THE WHITES AROUND
FRYEBURG, WHERE WINDS LIKELY STAY CALM LONG ENOUGH TO ALLOW FOR
AREAS OF FROST AS WELL. SOME PATCHY FROST CAN'T BE RULED OUT IN
THE TYPICAL COOL SPOTS OUTSIDE THE ADVISORY, BUT MOST OTHER
SPOTS LIKELY SEE LOWS IN THE UPPER 30S.
KEY MESSAGE 2 DESCRIPTION...
ANOTHER SHORTWAVE DIVES SOUTHWARD INTO NEW ENGLAND ON SUNDAY,
BUT IT WON'T BE NEARLY AS POTENT AS TODAY'S SYSTEM. CLOUDS
BLOSSOM SOUTHWARD THROUGH THE MORNING, WITH AFTERNOON SHOWERS
AND THUNDERSTORMS DEVELOPING ACROSS THE AREA. WITH FALLING
TEMPERATURES ALOFT, SOME SMALL HAIL IS LIKELY TO ACCOMPANY SOME
OF THE HEAVIER SHOWERS AND STORMS. AFTER REACHING INTO THE MID
TO UPPER 60S BY EARLY AFTERNOON, TEMPS FALL BACK IN THE
AFTERNOON WITH THE PASSAGE OF ANY SHOWERS AND STORMS. SOME
SCATTERED SHOWERS REMAIN POSSIBLE THROUGH THE OVERNIGHT SUNDAY
NIGHT AS THE LOW MOVES THROUGH, BUT WON'T BE AS ROBUST OR
WIDESPREAD AS DURING THE DAYTIME.
KEY MESSAGE 3 DESCRIPTION...
ANOTHER SHORT WAVE TROUGH SWINGS SOUTHWARD THROUGH THE REGION ON
MONDAY ALONG WITH ITS ASSOCIATED COLD TEMPERATURES ALOFT. THIS
WILL ALLOW FOR OCCASIONAL SHOWERY PERIODS WITH A FEW
THUNDERSTORMS POSSIBLE IN THE AFTERNOON WHERE SOME LOW CAPE
VALUES CAN DEVELOP, ESPECIALLY INLAND. GIVEN CLOUDS AND SHOWERY
PERIODS, TEMPERATURES WILL ONLY RISE INTO THE LOWER TO MID 60S.
THE UPPER LEVEL TROUGHING GRADUALLY GETS REPLACED BY SHORT WAVE
RIDGING ON TUESDAY WHICH WILL AID IN LESS SHOWERY WEATHER. WHILE
WE ARE GOING WITH LOW CHANCE POPS FOR MOST OF THE FORECAST AREA,
NOT EVERYONE WILL SEE RAIN. HIGHS WILL WARM UP SOME, UP TO ABOUT
70 DEGREES AT MANY LOCATIONS.
OVERHEAD RIDGING WITH FURTHER STRENGTHEN ON WEDNESDAY AND
THURSDAY WITH DRY WEATHER EXPECTED WITH HIGHS IN THE 70S ON
WEDNESDAY AND AROUND 80 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.
AVIATION /00Z SUNDAY THROUGH THURSDAY/
THROUGH 12Z MONDAY...
VFR CONDITIONS PREVAIL THROUGH THE OVERNIGHT AND SUNDAY MORNING.
PERIODS OF MVFR TO BRIEF IFR VISIBILITIES ARE THEN POSSIBLE THROUGH
THE AFTERNOON AND EVENING HOURS AS SCATTERED SHOWERS AND STORMS ARE
POSSIBLE AT ALL TERMINALS. A FEW OF THE STRONGER STORMS COULD
PRODUCE SMALL HAIL. A FEW SHOWERS WILL REMAIN POSSIBLE SUNDAY NIGHT
WITH SOME SCATTERED MVFR CEILINGS.
OUTLOOK:
MONDAY: SCATTERED SHOWERS MAY BRING LOCALIZED RESTRICTIONS FOR
BRIEF PERIODS OF TIME. WINDS ARE EXPECTED TO BE EASTERLY AT 5 TO
10 KNOTS TURNING LIGHT SOUTH DURING THE AFTERNOON.
TUESDAY: VFR WITH WIDELY SCT SHOWERS POSSIBLE. LIGHT NORTH WINDS
BECOMING SOUTHERLY ON THE COASTAL PLAIN DURING THE AFTERNOON.
WEDNESDAY: VFR WITH LIGHT SOUTHERLY WINDS.
THURSDAY - FRIDAY: HIGH PRESSURE IS FAVORED WITH VFR CONDITIONS.
MARINE
ANY LINGERING STORM AND GALE FORE WINDS EASE THIS EVENING ACROSS THE
OUTER WATERS. SCA CONDITIONS CONTINUE ALONG THE COASTAL WATERS AND
INTO CASCO BAY AS SEAS REMAIN ABOVE 5FT MOST OF THE NIGHT. SEAS
GRADUALLY FALL BELOW 5FT FROM NORTH TO SOUTH FROM LATE TONIGHT
THROUGH TOMORROW AFTERNOON. HIGH PRESSURE PASSES THROUGH THE GULF OF
MAINE ON SUNDAY, THEN A WEAK LOW PRESSURE SYSTEM CROSSES THROUGH
SUNDAY NIGHT.
UNSETTLED PATTERN PERSISTS INTO MONDAY WHILE WINDS AND SEAS
GENERALLY STAY BELOW SCA THRESHOLDS. FAIR WEATHER TUE-FRI WITH
WINDS AND SEAS REMAINING BELOW SCA THRESHOLDS.
