According to the RAP surface data, the temperature near Taunton is 78 degrees. Worcester is currently at 85, the old record high was 84.

A cold front will pass through the area overnight entering the area at about 6z. The forecast area looks dry but there is a slight chance for the southernmost tip of the precipitation line with this low but not likely. There is some frontogenesis at the surface according to the mesoanalysis page; the problem is that the air is just too dry to formulate precipitation as of now.

Once the front pushes of on Tuesday late morning, temperature will drop to near 40 Tuesday night, with highs on Wednesday near 60. A high pressure system will dominate and keep the forecast area pretty quiet.

Friday night into Saturday can get interesting if the low moves more southeast. As of now, the track of the low shows the precipitation northwest of the state. Models are in fairly good agreement right now so it looks dry right now but as the low continues to puss northeast, expect shows to enter the area on Saturday.

Another system looks to be moving into the area early next week but the timing is still uncertain. As of now the ncep model output for the GFS shows showers entering the area early Sunday and the heaviest showers Monday night into Tuesday. Expect highs for Sunday and Monday near 60.
