NH1 First Alert Weather: It's wet out, expect an unsettled stretch of NH weather
NH1 Chief Meteorologist
A cold front will be slowly be making its way east Tuesday morning, so scattered light rain showers will be ongoing during the hours of 5 am until 9 AM. Clouds will hold for most of the morning into the early afternooon. We should start to see some clearing from west to east during the afternoon, with temperatures behind the front warming to near 70-75 with the increasing sun and warming SW wind at the surface.
As the front moves this evening, low pressure strengthens along it, causing northeasterly onshore winds to develop. This will send cool, moist air southwestward through Maine and into New Hampshire overnight. For the most part, this will just consist of cloud cover, but cannot rule out some drizzle as well overnight.
Unsettled weather is likely in the long term as models are showing a stalled front to our east and a large cutoff low to our west through the period. This will result in an extended period of northeast winds that will keep the region cool and cloudy with periodic scattered showers and areas of drizzle.
A few periods of steady rain are possible as the upper low moves past us later in the week into the weekend. The big question is how much rain will this system produce? It definitely does not look like any heavy rains are going to happen, but at times it could be light. It looks like the heaviest rain will remain to the south and west of the forecast area, closer to the closed upper low with highs mostly in the Lwr to mid 60's right into the weekend.
