DAYS 1-5 (JUNE 18-22)
A 4-day stretch of unsettled weather with waves of low pressure passing along a frontal boundary to the south of New England today and again Wednesday, the first bringing a shot of wet weather to the region later this morning into this afternoon, lingering longest to the south, the second confining itself mostly to the South Coast Wednesday while both late today and late Tuesday some showers may pop up along a convergence zone between ocean air and non-ocean air somewhere north and west of Boston. The third in the series of low pressure areas will not only be the strongest but also take a track just north of southern New England, bringing the most moisture, the heaviest rainfall threat, and a chance of thunderstorms, most of it occurring Thursday night, with wet weather lingering into Friday as the low pulls away. Drier air will be returning by later Friday and will set the region up for a nice start to the upcoming weekend as high pressure approaches, but a gusty breeze that develops during Friday between the departing low and approaching high may continue into Saturday.

DAYS 6-10 (JUNE 23-27)
Great weather hangs on to finish off the weekend on June 23. A low pressure wave brings a threat of wet weather June 24. The June 25-27 period should be mostly fair, but not without a shower or thunderstorm threat a couple times, and overall warmer.
DAYS 11-15 (JUNE 28-JULY 2)
West to east flow over a high pressure ridge to the south and west of New England is a pattern that brings warm to occasional hot weather in, is rain-free most of the time, but also provides a few opportunities moving along the jet stream to bring a shower/t-storm threat. This is the pattern currently expected for this period.
