KEY MESSAGE 1...Dry weather continues through the weekend and much of next week. Cool today, with afternoon temperatures gradually moderating this weekend, though chilly mornings will bring widespread frost to much of the area away from the immediate coast.

As anticipated, Subtropical Storm Josephine has undergone extratropical transition, now Post-Tropical Cyclone Josephine per the National Hurricane Center. This system is moving east and will pass to the south of Nova Scotia and New Brunswick Friday into Saturday. With the center of the system moving further east into the North Atlantic Ocean, expansive high pressure builds across the Northeast. Thus, any lingering gusts of 20 to 30 mph will be confined to the easternmost waters and adjacent coastal areas, particularly from Cape Ann to Cape Cod and the Islands. Winds diminish late this morning into the afternoon, while areas farther inland will be treated to a pleasant day with light northerly winds of 5 to 10 mph. Full sunshine today with highs ranging from the lower to middle 50s.

Looking ahead, there really isn't any sensible weather to discuss as the aforementioned high pressure system remains the dominant weather feature for the foreseeable future. However, a weak cold front starved of moisture approaches from the north-northwest on Tuesday. Strong high pressure and dry air will likely cause this front to dry out before reaching southern New England, perhaps adding some cloud cover at most. In fact, global ensembles paint a rather parched picture for southern New England, with probabilities of measurable precipitation (0.01 inches or greater) generally less than 10 percent from Friday through Wednesday of next week.
