Very late update!
DAYS 1-5 (JULY 31-AUGUST 4)
New pattern becoming established now, high pressure off the East Coast, trough develops to the west. As previously stated, this results in a more classic summer feel and brings the risk of showers and storms at times, but no wash-out days.
MONDAY: Mostly sunny. Highs 77-82 coast, 82-87 interior. Wind light S with sea breezes.
TONIGHT: Partly cloudy. An early shower Cape Ann MA. Lows 62-68. Wind light variable.
TUESDAY: Mostly sunny. Highs 80-88 but cooling back slightly coastal areas. Wind light variable with sea breezes.
WEDNESDAY: Partly cloudy. Isolated afternoon thunderstorms. Humid. Lows in the 60s. Highs in the 80s.
THURSDAY: Partly sunny. Scattered afternoon thunderstorms. Humid. Lows from the upper 60s to lower 70s. Highs from the middle 80s to lower 90s, cooler South Coast.
FRIDAY: Variably cloudy. Scattered showers and isolated thunderstorms, ending late. Humid. Lows from the upper 60s to lower 70s. Highs in the 80s but cooler South Coast.
DAYS 6-10 (AUGUST 5-9)
A pattern of high pressure off the East Coast and a trough of low pressure centered around the Great Lakes will result in humid weather with occasional opportunities for showers and thunderstorms during this period. The greatest shower/storm threat appears to be around August 6, but will depend on position of trough and other factors, so much fine tuning will take place in the days ahead.
DAYS 11-15 (AUGUST 10-14)
Similar pattern but stronger high pressure and weaker trough means warmer to hotter and more isolated shower/thunderstorm activity during this period.
