DAYS 1-5 (JULY 14-18)

Today we turn up the heat and humidity but keep it breezy between high pressure to our south and a vigorous low pressure area moving across southeastern Canada. The latter will trigger strong to severe thunderstorms in southern Quebec and northern New England later today into this evening, but that activity will fade as it heads southward, surviving as a few showers and possibly a thunderstorm in to southern NH and northern MA Wednesday morning, and regenerating as mainly isolated showers and storms south of I-90 midday into afternoon Wednesday before its triggering frontal boundary pushes away. That boundary will serve to knock down the humidity Wednesday while it will still be fairly hot. Another front heads southward into the region on Thursday and can trigger a few more showers and thunderstorms mainly later in the day, but that day will not be as hot as Wednesday. The cooling trend will continue into Friday as the second front pushes through the region and off to the south. Currently, I expect Saturday to feature fair weather, though there may be some high and mid level clouds to contend with, however it should be quite comfortable to be outside that day.

TODAY: Smoke-filtered sunshine along with patchy clouds. Highs 74-81 Nantucket and Outer Cape Cod, 82-89 remainder of South Coast, 90-97 elsewhere. Dew point climbs to middle / upper 60s. Wind SW 10-20 MPH.

TONIGHT: Mostly cloudy. An overnight shower or thunderstorm possible in southern NH and northern MA. Lows 66-73. Dew point 60+. Wind W 5-15 MPH.

WEDNESDAY: Partly sunny. A morning shower possible mainly in MA and then isolated midday to mid afternoon showers and thunderstorms possible south of I-90. Highs 80-87 Nantucket and Outer Cape Cod, 88-95 elsewhere. Dew point falls below 60. Wind W to NW 10-20 MPH, diminishing later in the day.

WEDNESDAY NIGHT: Mostly clear. Lows 63-70. Dew point sub-60. Wind NW up to 10 MPH.

THURSDAY: Partly cloudy. A shower or thunderstorm possible mainly southern NH and eastern MA late afternoon or evening. Highs 83-90. Dew point briefly spikes 60+. Wind W 5-15 MPH, gusts over 20 MPH.

THURSDAY NIGHT: Clear. Lows 60-67. Dew point falls to 50s. Wind NW 5-15 MPH.

FRIDAY: Sun and passing clouds. Highs 78-85. Dew point stays in 50s. Wind N 5-15 MPH but with coastal sea breezes developing.

FRIDAY NIGHT: Partly cloudy. Lows 58-65. Dew point 55 or lower. Wind N up to 10 MPH.

SATURDAY: Variably cloudy. Highs 78-85, coolest coast. Dew point in 50s. Wind NE to E up to 10 MPH.

DAYS 6-10 (JULY 19-23)

Still leaning dry but watching for the chance of a disturbance being close enough for a shower threat on July 19, but more likely to see higher humidity and shower chances the first half of next week. Temperatures somewhat variable but around normal overall.

DAYS 11-15 (JULY 24-28)

Drier early through mid period before shower and thunderstorm chances increase later in the period. Temperatures near to above normal.
