NH1 Weather Insider with Joe Joyce: November 10, 2015
NH1 Chief Meteorologist
A frosty start to Tuesday with some sunshine holding on strong. High pressure off the coast is still supplying enough sinking stable air to help keep most of Tuesday day dry along with a light wind from the east. High to mid-level clouds will be increasing during the day, so I expect a fading sunshine and a trend to more and more clouds with highs in the mid 50's. The dry air will win out even into a portion of Tuesday night, but rain will be spreading into Southern New England. Rain will begin to spread into New Hampshire around midnight Tuesday night and early Wednesday morning. Rain will fill in for the overnight and through much of the day Wednesday. A deepening low will track just off the coast of Cape Cod, bringing gusty winds for SE MA, but here in New Hampshire I expect the highest gust to be around 30 mph at the coast Wednesday morning.
The latest info is showing the worst weather happening Wednesday morning, with rain tapering to showers and ending Wednesday afternoon. Breezy NNE winds wrapping in behind the departing low, along with the wet conditions will make for a wet and raw day in the 40's. Generally, I expect about .25-.75" of rain to fall from 12 AM Wed-5 PM Wednesday. Drier air will settle in Wednesday night with the raindrops completely ending. A dry start to Thursday, before more clouds and showers arrive. A strong wave of low pressure will track up through the Great Lakes and into Canada. This will whip around another cold front and batch of showers which will be pushing through Thursday afternoon and evening.
Behind this front, dry west winds with building high pressure will bring back the sunshine and more seasonal temps in the Lwr-mid 50s. An upper level trough will swing into the Northeast behind this cold front, and direct in a cooler airmass with highs in the 40's and Lwr 50's. I expect a mostly dry breezy cool weekend with Sunday likely being the brighter of the two weekend days. Saturday will see more clouds in the mountains with the risk of mountain snow showers!
