Mother Nature has decided it’s more of a trick than a treat for this Halloween Evening as an area of rain is racing into much of northern MA and southern NH, wetting areas especially north of the Mass Pike, with less activity in south central and southeastern MA and across RI. Enough activity is generating upstream to keep the chance of wet weather going, especially in northern MA and southern NH, right through the evening, then expanding into all areas during the night and through Friday morning. All the while, warm and humid air will be moving into the region on increasing southerly winds. After the low pressure area and frontal system responsible for this wet weather clears the region later Friday, we’ll have a period of drier weather, but a second cold front will cross the region Saturday night with more clouds and a rain shower risk as mild air will hang on until that front passes. By Sunday, we’ll be into a stronger northwest wind flow, transporting much cooler and drier weather.
A peak into next week shows that we’ll have a chilly start and a warming midweek with dry weather expected, as we start first with a cold airmass from Canada then build a ridge of high pressure along the East Coast, which may bring Indian Summer conditions by the middle of the week.
