It's looking less favorable for a dry start to trick-or-treating. Showers may move into western Mass and southern N.H. by 2 p.m. The Boston area will probably have showers by 5 p.m. Southeastern Mass may be the lucky spot for dry weather this evening! Elsewhere, especially along and north of the Mass Pike, intermittent rain is likely.
Winds from the south will carry warm and muggy air into the region for Halloween. The result will be highs in the lower 60s and near stationary evening temps in the upper 50s.
It will be humid and warm tomorrow with highs around 70! BUT, it will be a soaker.
Rain will get heavier by daybreak Friday. Heavy showers and gusty winds will rule the forecast. Totals 0.5" to 1.5" are possible with gusty, possibly damaging wind gusts to 45 in Boston, up to 60 mph on the Cape.
The strongest wind will impact southeastern Mass. A High Wind Watch has been issued from 5 AM to 4 PM for sustained SW winds 20-35 mph and gusts 50 to 60 mph there. This is damaging wind capable of taking down tree limbs and causing power outages.
Showers will wind down in the afternoon and push offshore by evening. Friday night plans look dry.
Rain may linger over the Cape Saturday if the front gets stuck. Elsewhere dry conditions with highs in the lower 60s are forecasted early weekend as we prepare for the Red Sox Parade.
