NH1 Weather Insider with meteorologist Bill Gile for May 18, 2015


Low clouds and fog will be moving for Monday morning as a back door front drops down from Maine causing the winds to shift out of the east-northeast and of course you know what that means, cooler temperatures for Monday! High pressure will slide southwestward at us from Nova Scotia and push that backdoor cold front out to just about the CT river valley. That looks to be about as far as it will go. Temperatures will drop noticeably to the east of the frontal boundary with highs only in the 50's at the coast and 60's inland. Low clouds will continue to back in as well and there may be some spotty drizzle or mist along the coast, especially in the morning. During the afternoon those low clouds will begin to break up region-wide and for residents near the CT river valley your temperatures will rise to 70 degrees or better as the marine influence will lose its effect.
Tuesday is going to be a changeable day. An area of showers will move through during the morning as a weak warm front come in. Then some sunshine will develop for midday which will begin to create unsettled conditions in the atmosphere while a cold front approaches from the west. The combination of these two factors will be enough to create another of round showers for the afternoon along with potentially strong thunderstorms. Rainfall amounts from the shower activity is expected to be about 0.1 – 0.2 inch. However, any thunderstorms could produce additional locally heavy downpours. If T-storms do form and they become strong, gusty winds and small hail may also be realized, so keep an eye to the sky.
Once that cold front moves by it will cool a bit for Wednesday along with breezy conditions. A general area of High pressure builds in with for the Thursday through Saturday stretch with a good deal of sunshine and low dewpoints(dry air). That means temperatures will rise into the 70-75 degree range during the day, but the evenings will cool quickly with the setting sun and the mornings will be a bit chilly around sunrise.
Have a great week!
