AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAY ME
703 PM EDT TUE AUG 11 2026
WHAT HAS CHANGED
NO MAJOR CHANGES NEEDED THIS EVENING AS THE FORECAST REMAINS ON
TRACK. JUST TWEAKED NEAR TERM TRENDS TO ALIGN WITH OBSERVATIONS AND
UPDATED THE AVIATION DISCUSSION FOR THE 00Z TAFS.
KEY MESSAGES
1. MAINLY FAIR WEATHER EXPECTED TONIGHT THROUGH WEDNESDAY NIGHT WITH
WIDELY SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS POSSIBLE
WEDNESDAY AFTERNOON WITH LOW POTENTIAL FOR GUSTY WINDS.
2. SHOWERS AND STORMS ARE LIKELY TO END OUT THE WEEK, WITH MOSTLY
DRY WEATHER EXPECTED OVER THE WEEKEND. ASTRONOMICAL TIDES WILL BE AT
A MONTHLY HIGH, BUT IMPACTS SHOULD REMAIN MINIMAL.
DISCUSSION
KEY MESSAGE 1 DESCRIPTION...
OTHER THAN LOCALLY DENSE VALLEY FOG TONIGHT THE WEATHER WILL BE
FAIR. RADIATIONAL COOLING WILL BRING TEMPERATURES DOWN INTO THE 50S
IN OUTLYING AREAS, WITH A FEW SPOTS IN NORTHERN NH POSSIBLY REACHING
THE UPPER 40S. HAVE HEAVILY BLENDED IN THE MET AND MAV GUIDANCE FOR
LOWS.
A WEAK SHORT WAVE TROUGH WILL APPROACH NORTHERN NEW ENGLAND
WEDNESDAY. THIS FEATURE COUPLED WITH AT LEAST WEAK INSTABILITY
SHOULD ALLOW FOR WIDELY SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS
DURING THE AFTERNOON HOURS. WITH SFC DEWPOINT DEPRESSIONS AROUND 20F
GUSTY WINDS COULD OCCUR IN CONVECTIVE SHOWERS AND STORMS. HOWEVER,
COVERAGE WILL BE WIDELY SCATTERED AND MOST LOCATIONS WILL LIKELY
REMAIN DRY. VALLEY FOG WILL BE LIKELY ONCE AGAIN LATE AT NIGHT.
KEY MESSAGE 2 DESCRIPTION...
A WEAK TROUGH AXIS SWINGS INTO THE AREA THURSDAY AFTERNOON AND IS
LIKELY TO PERSIST THROUGH FRIDAY. DURING ITS PASSAGE, SHOWERS AND
STORMS ARE POSSIBLE, BUT PWATS IN THE RANGE OF 1.1-1.5 INCHES SHOULD
ALLOW FOR SHOWERS TO BE FAIRLY SCATTERED RATHER THAN MORE WIDESPREAD.
IN ADDITION, WE WILL NEED TO KEEP AN EYE ON THE HIGH TIDES FOR
THURSDAY. ASTRONOMICAL TIDES ARE HIGH FOR THE MONTH, AND THE TIDE
GAUGES WILL BE CLOSE TO REACHING MINOR FLOOD STAGE. HOWEVER, LIGHT
OFFSHORE WINDS AND VERY LOW WAVE HEIGHTS COULD ALLOW FOR SOME HIGH
WATER ALONG THE COAST, BUT OTHERWISE IMPACTS SHOULD BE MINIMAL.
OVER THE WEEKEND, A MID-LEVEL RIDGE MOVES INTO THE AREA. RIDGING AND
HIGH PRESSURE SHOULD ALLOW FOR DRY AND PLEASANT WEATHER, WITH HIGH
TEMPERATURES FORECAST NEAR 80F.
AVIATION /00Z WEDNESDAY THROUGH SUNDAY/
THROUGH 00Z THURSDAY...VALLEY FOG AT HIE AND LEB LIKELY TONIGHT AND
WEDNESDAY NIGHT. THE SEABREEZE WILL LIKELY COME ASHORE DURING THE
AFTERNOON AT COASTAL TERMINALS. WIDELY SCATTERED GUSTY SHOWERS AND
POSSIBLY A THUNDERSTORM WEDNESDAY AFTERNOON MAY BRING ABOUT TEMPO
MVFR RESTRICTIONS, BUT CONFIDENCE IS TOO LOW TO INCLUDE IN THE TAFS
AT THIS TIME.
OUTLOOK:
THURSDAY-FRIDAY: PERIODS OF MVFR POSSIBLE DUE TO SHOWERS AND
THUNDERSTORMS.
SATURDAY-SUNDAY: VFR EXPECTED.
MARINE
WINDS AND SEAS WILL LARGELY REMAIN BELOW SCA CRITERIA THROUGH THE
WEEK AS A SERIES OF GENERALLY WEAK COLD FRONTS CROSS THE WATERS.
CONDITIONS MAY COME CLOSE TO SCA CRITERIA BRIEFLY FRIDAY NIGHT AND
INTO SATURDAY.
