NH1 Weather Insider with Joe Joyce: November 21, 2015

High-mid level clouds will be crossing through New Hampshire Saturday morning. These clouds are part of a strong low tracking into the Great Lakes. High pressure will be sitting over us all day with light onshore winds. I expect any morning clouds and filtered sun to give way to mostly sunny skies by the afternoon with highs in the 40's to near 50. The high will pull off the coast Saturday night and clouds will be increasing along with SE wind. As the low tracks into Canada, the main weather maker we will be watching is a cold front Sunday. Cloudy skies will be in place all morning, with a few morning showers possible breaking out along this front. What we will have to watch is a wave of low pressure developing on the front and enhancing some of the rainfall across eastern MA. Some of that steady rain may track up along the front and slow it down. This could mean it keeps raining across Southeast New Hampshire during the midday and early afternoon. This would also keep more clouds around across the interior for the rest of the day as well. It is something to watch for. For now, I expect a few morning showers through the midday then breaking afternoon clouds from west to east during the day with highs in the 40's near 50.
As the front pushes offshore, much cooler air will be directed into the northeast with an upper level trough and building high pressure at the surface. Highs on Monday will only be in the 30's to near 40 with mostly sunny skies. It will be the coldest air of the early cool season with temperatures running about ten degrees below normal. High pressure will be close by to provide sunshine and dry conditions for most of the week with cooler than normal air remaining through Wednesday. Temperatures will begin to moderate Thanksgiving day and eventually climb into the 50's by Friday with warmer SW winds. Some rain will be possible heading into next weekend.
