DAYS 1-5 (JULY 8-12)
The remains of Chantal clipped Cape Cod and the Islands with heavy showers and thunderstorms in the early morning hours today, but have exited that region. We’re left with a another humid day, quite warm (not as hot as yesterday most areas). A cold front moving through the region from north to south will trigger additional showers and thunderstorms in scattered / clustered form mainly this afternoon, with a second surge possible in some areas tonight into early Wednesday as the front becomes mainly stationary just to the south. A little push from high pressure to the northeast should then limit the shower chances to the South Coast and well west of Boston for the balance of Wednesday, before a disturbance from the west increases the chances and coverage from west to east on Thursday, tapering off Friday as the disturbance continues onward to the east. Weak high pressure takes over Saturday with better weather. I am optimistic that the previously-mentioned disturbance and shower chance for Saturday will be something that occurs north of our region.
TODAY: Variably cloudy. Scattered to clustered showers and thunderstorms this afternoon, some storms can be locally severe and some can produce torrential downpours with flooding. Highs 82-89 except 75-82 South Coast. Dew point 70+. Wind variable to SW 5-15 MPH.
TONIGHT: Variably cloudy. Patchy fog. Additional scattered to clustered showers and thunderstorms. Lows 66-73. Dew point middle to upper 60s. Wind variable to N up to 10 MPH.
WEDNESDAY: Mostly cloudy – some limited sun possible. Scattered showers anywhere early, then favoring areas south of I-90 and west of I-495 later on. Highs 75-82, coolest coast. Dew point 60+. Wind N to E up to 10 MPH.
WEDNESDAY NIGHT: Mostly cloudy. Patchy fog. Lows 61-68. Dew point 60+. Wind E up to 10 MPH.
THURSDAY: Mostly cloudy. Showers likely, especially midday and afternoon. Chance of a thunderstorm. Highs 71-78. Dew point in 60s. Wind E 5-15 MPH.
THURSDAY NIGHT: Mostly cloudy. Showers likely. Patchy fog. Lows 61-68. Dew point 60+. Wind E up to 10 MPH.
FRIDAY: Mostly cloudy. Showers diminish. Highs 71-78. Dew point in 60s. Wind E 5-15 MPH.
FRIDAY NIGHT: Partly cloudy. Lows 60-67. Wind E up to 10 MPH.
SATURDAY: Partly sunny. Highs 73-80, coolest coast. Wind E up to 10 MPH.
DAYS 6-10 (JULY 13-17)
Fair and warmer July 13 to finish off the weekend. Disturbance and frontal system brings a shower / thunderstorm chance to the region July 14 into July 15 followed by fair weather by the middle of next week. No major heat.
DAYS 11-15 (JULY 18-22)
Into mid period, moderate humidity and temperatures, mainly fair weather with high pressure to the north dominant, keeping low pressure to the south far enough away to limit shower chances. Later in the period some indications of high pressure building aloft with hotter weather again.
