It’s quietly continuing drier than normal, with long term rainfall deficits of 3 inches or more, and no significant rain in sight for southern New England.
A frontal system sitting southwest of the region is acting as an avenue for clouds, which have been fanning across the sky, especially over southern MA and RI, during Tuesday. These clouds will hang in for tonight with only a slight chance a touch of light rain goes across RI and far southern MA, but as we get into Wednesday, dry air wins out again and sunshine increases in all areas, continuing Thursday and Friday along with a moderating temperature trend as high pressure dominates.
The weekend should feature more sun then clouds Saturday and more clouds than sun Sunday as an early call, with mild air Saturday only cooling slightly on Sunday. We will be between a frontal system to the west, which will approach later Sunday, and forecast Hurricane Sandy in the western Atlantic. The track of Sandy and any possible interaction with the jet stream and US East Coast is still highly uncertain. The only reflection of this possibility will be in a forecast shower threat at the end of the period. Don’t read too much into it at this time, as there is plenty of time to work out what will happen early next week.
In the mean time, the forecast for eastern MA, RI, and southern NH…
