DAYS 1-5 (JULY 12-16)
A shot of heat and humidity visits our region today ahead of an approaching cold front. This front will trigger showers and thunderstorms late-day through late-evening from west to east across there region, but we will catch the system after maximum heating and with limited favorable dynamics, so while a few stronger storms are possible, the ability of this front to produce a lot of rainfall and any significant severe weather is very limited, so for the most part it should be an uneventful frontal passage except for those who see a downpour or thunderstorm. The humidity will drop during Wednesday behind this front, although it will be a very warm day. We do cool off a bit more Thursday, but delay the arrival of high pressure by a day as we have to wait for a disturbance to cross the region that will bring some cloudiness and the threat of a shower or thunderstorm. High pressure builds in with fair weather for both Friday and Saturday.
TODAY: Sun/cloud mix. Potential showers/thunderstorms by late-day, favoring north central to northeasternMA and southern NH. Highs 86-93. Dew point rising through 60s. Wind SW 10-20 MPH, higher gusts.
TONIGHT: Variably cloudy. Chance of showers and thunderstorms this evening anywhere in the region, ending from west to east late evening. Areas of fog. Lows 63-70. Dew point 60s. Wind SW to variable 5-15 MPH.
WEDNESDAY: Lots of clouds early with a shower possible South Coast, otherwise sun/cloud mix. Highs 85-92. Dew point falling through the 60s. Wind variable up to 10 MPH early, then NW 5-15 MPH.
WEDNESDAY NIGHT: Mostly clear. Patchy fog interior valleys. Lows 57-64. Dew point upper 50s. Wind W under 10 MPH.
THURSDAY: Partly sunny. Chance of showers and possibly a thunderstorm. Highs 78-85. Dew point upper 50s. Wind NW up to 10 MPH with coastal sea breezes possible.

DAYS 6-10 (JULY 17-21)
A low pressure area and frontal boundary will move into and slowly across the region later July 17 through July 18 with an opportunity for showers and thunderstorms. Drier and slightly cooler for the middle of the period before a shot of warmer/hotter and more humid air and a chance of showers/thunderstorms appears to end the period, based on current timing.
