NH1 Weather Insider with Joe Joyce: January 27, 2016

The January Thaw keeps on marching along, but that does not mean there will not be a few bumps in the road. Tuesday had highs in the 40's to near 50 in southern New Hampshire, close to to 20 degrees above the average! A cold front has pushed through so Wednesday will be slightly cooler with Partly sunny skies and highs in the Lwr 40's by afternoon. Another cold front will push through this afternoon with a few clouds, and even a few snow showers in the mountains. Behind this front, cooler air returns to New Hampshire tonight with clear skies and lows dropping into the teens early Thursday morning.

Thursday will start off cool with sunshine for most of the day. A few clouds may try to increase before sunset along with SSW wind and highs still in the 30's to near 40. An upper level trough will swing through the Northeast Friday and will provide enough lift in the atmosphere for more clouds and the risk for scattered afternoon snow showers and flurries. Maybe even a coating of snow will be possible. Again highs will be in the 30's during the afternoon.

The Weekend is looking pretty good at this point. I expect a mix of sun and clouds with temperatures starting of a bit cool on Saturday. Temperatures will rise into the mid-upper 30's by afternoon. Cold air will continue to lift out and temperatures will moderate for the second half of the weekend under a building ridge of high pressure with sunshine on Sunday and highs climbing into the 40's!

A weak cold front will push through Monday with a few clouds and a passing shower. A surge of mild air under SW winds ahead of this front will spike highs to near 50. It will become slightly cooler Tuesday behind the front, but highs will remain in the 40's during the afternoon in the sunshine. Upper level ridging across the east will allow temps to climb into the 50's by the middle of next week, so yes...this is definitely a January thaw as we will be stringing together a run of day running 5-10 degrees above normal. Enjoy.

Consider this January that the halftime of winter. It will be a time for you and the atmosphere to catch your breath. But it looks like winter will come out ready to play in the second half! Colder Arctic air will be returning by February 5th or 6th. It will likely be the kind of cold that can change a weather pattern. The Polar Vortex, the upper level winds in the upper troposphere, Lower stratosphere which helps to direct cold air from Canada into the United States is showing signs of coming back to lift for the middle to end of February and possibly into March. There is plenty of legs left to winter, with another round of cold Arctic air and a few more chances of snow storms in the buckling jetstream pattern an almost certainty. Warm thoughts!
