NH1 Weather Insider with Joe Joyce: December 8, 2015

A cooler day can be expected on Tuesday as an area of low pressure will be tracking southeast of Nantucket and remaining well offshore. Rain will be clipping Southeast MA, especially the Cape & Islands. While New Hampshire will be dry, clouds from this low will be in place across SNH during the morning into the midday. Skies will be partly sunny farther inland across the interior. As the low pulls away, drier air will wrap in on the backside during the afternoon, so areas with clouds should see some increasing afternoon sun. A light NE wind supplied by high pressure to our north, will help to keep temperatures running about 10-15 degrees cooler compared to the balmy 50's of Monday. I expect highs on Tuesday to rangge from the upper 30's to Lwr 40's during the afternoon.
Weak high pressure will sit over us Wednesday with partly sunny skies and afternoon highs slightly warmer in the Lwr-mid 40's, still running above the average of 39 degrees for this time of year. High pressure will pull off the coast and wrap in a milder southerly wind with temps climbing to near 50. Low clouds will back in off the water,as an upper level disturbance will slide over us providing lift and enhance cloud cover with the risk of a passing shower inot early Friday. It will be a mainly dry outlook through the end of the week.
On Friday, a warm front over us will be lifting north with skies turning partly sunny again. Mild winds will push temps into the Lwr 50's. High pressure south of New England with a building upper level ridge over us will help to supply sunshine to kick off the weekend along with warming SW winds at the surface with highs climbing back into the 50's. The mild air will hold right into Sunday with partly sunny skies and mild winds from the south.
There are a few questions which track our next weather maker will take...will it go south of us Monday with the potential for rain and snow or track into the Great Lakes with a mild rain for the Northeast Monday. I am leaning towards the warmer rainy scenario for now. We will see how the trends go this week as it is still far away. Either way, if you are looking for Arctic air, it is locked up in the North Pole, over Alaska and Siberia for now. Temperatures are cooler, but there is nothing terrible cold, and nothing dramatic which can cause a pattern to change and adjust. Despite the periodic cool shots, there will still be periods of warm to enjoy leading right into Christmas. The forecasts of a milder December are likely to pan out when all is said and done.
We have also been seeing one of our models being quite consistent calling for a warmer than average January for much of the northern half of the US! Thank you El Nino! Welcome news for those looking for a break from winter. This comes as a warning to skiing enthusiasts that this winter is likely going to be a bit of a struggle.
