Thursday will be another fine day across the region, but it will be cooler, especially across eastern sections of the state closer to the cooler onshore wind. High pressure off the coast is wrapping in a cool onshore SE flow, which will keep temps in the 50's to near 60 at the coast, with temperatures in the 60's to near 70 farther inland. Western valleys will be the warmer spots today climbing into the 70's. We will have to watch for a few ocean clouds backing in off the water from time time, otherwise it is a seasonally cooler partly sunny Thursday.
Thursday night will feature an increase in cloud cover late in the day ahead of a warm front that will be slowly approaching from the west. There will be a slight chance for an evening shower, otherwise it will remain dry. More patchy fog with possibly some drizzle is expected Thursday night as a southerly flow develops off the Gulf of Maine and into a slow cold front that will be situated over eastern New York State. Showers will overspread some communities from west to east overnight. The atmosphere will be relatively stable, so will not include the chance of thunderstorms at this time. Precipitation will remain relatively light overnight, but Friday morning will likely start off cloudy and damp.
A Large low, currently over northern Minnesota will track east into Canada. A trailing frontal boundary will push eastward as well. A cold front will move across the area on Friday, with a few showers possible as it does so. It`s starting to look like the best forcing for precipitation is going to be further to the north, so rain chances are not quite as high Friday, though it will be cloudy. Most likely the frontal boundary will be weakening as it crosses over us, with just a small chance of a shower. Temperatures will be warming into the 70's and Lwr 80's with a wind shift to the SSW during the afternoon. Any breaks of sun inland will spike temps to near 80 during the afternoon.
High pressure builds into the area out of the northwest Saturday and Saturday night. With sunshine, and light variable winds, temperatures should spike into the 80s, with 70's at the coast. The next low rumbling through the Great Lakes on Sunday will gradually spread moisture and lift into New England in the form of rain Sunday. This rain will becoming from the Gulf States. Upper level winds from the SW will directed the rain showers, downpours and thunderstorms into the Northeast. Rain will begin sometime during the late morning and continue into the afternoon and evening hours with periodic heavy bursts of rain. Generally 1 to 2 inches of rain is possible which should not be too big of a deal especially considering the dry conditions we've had. Plume of precipitation funneling into the low shifts to the north and east on Monday, ending the steadier precipitation for our area. However, the upper low lingers near the area and will keep some minor instability in place through midweek. Cooler NW winds behind the departing Low Monday will bring cooler air from Canada with highs in the Lwr 70's Tuesday & Wednesday.
