DAYS 1-5 (JUNE 29 – JULY 3)
Low pressure, with more potency than most forecast indicated, triggered quite the thunderstorm event for a good portion of the region during Sunday. We’ve heard the stories by now, so it’s time to look ahead to what else it has in store for us, and that is 3-days of unsettled weather to end the month of June and start July. I think today and Tuesday will the 2 coolest and least sunny of the 3 days, but any sun that does occur will help fuel the development of showers and possible thunderstorms, which will be around all 3 days anyway. Timing-wise, I think activity can occur pretty much any time today and Tuesday and will be weighted more toward afternoon favoring areas further south and west on Wednesday. The upper low finally loses its grip on us with a sliver of high pressure to make Thursday a nicer summer day, and while Friday also looks dry it will be cooler with a new surge of Canadian air via the Canadian Maritimes.
TODAY: Mostly cloudy to partly sunny. Scattered showers and thunderstorms. Highs 68-73 coast, 73-78 inland. Wind calm then NE up to 10 MPH.

DAYS 6-10 (JULY 4-8)
Independence Day Weekend July 4-5 looks fair with moderate temperatures due to Canadian high pressure in control, coolest likely along the coast. Warmer and more humid weather returns in the July 6-8 period with a slight increase in the risk of showers and thunderstorms.
DAYS 11-15 (JULY 9-13)
Expecting a shift toward a shift to a more zonal flow pattern with minor disturbance, mainly dry weather, and temperatures near to above normal.
