Strengthening high pressure to our north and a nearly stationary low pressure system to our south will be the two main weather features over the next several days.
Today, we find ourselves somewhat in a battle zone with the high keeping us dry but cloudiness filtering in overhead from the low to our south. A cool northeast breeze will keep temperatures from recovering beyond the low 60s, perhaps not getting out of the upper 50s along some coastal communities.
Tonight, moisture from the low wants to push northward while drier air to our north tries to keep the moisture at bay. We will be right on the fringe of the northern edge of the precipitation shield tonight and it is possible that a few sprinkles or light showers occur overnight. The Merrimack Valley could remain dry altogether as the further south you go the better chances are for a shower. On the flip side it is entirely possible that nobody gets any precipitation overnight. Lows will fall to the upper 40s, to a few low 50s right along the coast. Light northeast winds continue.
Friday will remain generally cloudy, although a few peeks of sun is possible through the Merrimack Valley. There also remains a chance of a few showers, especially south of the Merrimack Valley. Cool temperatures remain in place with the onshore flow continuing. Highs in the low 60s.
Friday night, clouds win out and some areas of patchy fog develop. A bit of drizzle is possible as well. Lows in the upper 40s to low 50s.
Saturday, high pressure to our north may begin to win the battle and suppress the clouds southward. After some early fog and cloudiness we are somewhat optimistic the sun returns in the afternoon, especially away from the coast. Highs remaining in the low 60s, perhaps not quite reaching 60 right along the coast.
Saturday night, partly to mostly cloudy. Chance for areas of fog redeveloping. Lows around 50.
Sunday and Columbus Day, generally partly cloudy through the period. Highs in the low to mid 60s. Overnight lows in the mid 40s to 50 degrees, coolest inland.
