NH1 First Alert Weather: Rainy Thursday, Cooler Weekend
NH1 Chief Meteorologist
Keep the raincoats handy! Low pressure will push in from the west on Thursday with rain overspreading the region during the morning and early afternoon hours. Looking like rainfall totals through Thursday night generally in the quarter to half inch range. Highs on Thursday will be in the Lwr 50s as the developing rain will help to cool the atmosphere and break down the left over warmth from Wednesday. Low pressure will head east through the Gulf of Maine Thursday night. Expect rain to taper to scattered lighter showers from west to east during the evening. Clouds will become partly cloudy overnight. Please scroll down below to see the timing of the rain today and when you can expect the heaviest of the rain to push through.
An Upper level trough will remain in place for most of the weekend thanks to atmospheric blocking. This will allow Arctic air to travel towards the east coast. A large area of high pressure will push in from the NW bringing clear to sunny skies for the coastal plain thanks to downsloping winds. In addition it looks quite breezy with deep mixing and cold air advection not allowing readings above the mid 30s in the north country to upper 40s south. Gusts will probably top out around 30 mph. Although the high temperatures will be slightly below normal for this time of year, it will seem much colder with the wind factored in. Friday night into Saturday morning looks like the chilliest period in the long term and expect the majority of locations to have a hard freeze early Saturday morning.
Saturday will start off with some sunshine, with building afternoon clouds thanks to the cooler air aloft. Highs will remain in the 40's to near 50. Upsloping mountain snow showers will be possible in the cool NW flow. A reinforcing shot of cold air arrives Saturday night into Sunday. Cooler weather will persist through early next week. Eventually the upper level trough cuts off and shifts into the Atlantic allowing ridging to build into New England and bringing a return to warmer weather just in time for Election day with highs climbing back into the 50's
