NH1 Weather Insider with Joe Joyce: February 6, 2016
NH1 Chief Meteorologist
It is going to a be a great weekend with plenty of sunshine, and cooler temperatures. Cooler is relative, because it will be cooler than the spring-like warmth we have become used to lately, but temperatures will still be slightly above the average for this time of year. High pressure south of New England, along with upper level ridging will help to make Saturday a mostly sunny day. Temperatures will start off cool and then moderate into the 30's to near 40 by the afternoon with winds shifting to the SW. Clouds will increase a bit during the afternoon and will have skies becoming partly sunny. A weak front will begin to push through on Super Bowl Sunday. Plenty of sunshine can be expected Sunday with highs climbing into the Lwr 40's by the afternoon.
Once the cold front pushes off the coast, a much colder air mass will be in place to start the week on Monday. Temperatures will only be in the 20's. The day will start off dry, and we will be watching a storm off the Carolina coastline start to strengthen and deep rapidly and track up the east coast. The pressure in the center in the low may fall as deep as 960 mb which is incredible strong. The pattern remains complex, but we are watching the trends in our computer models. We are watching 2 or 3 pieces of energy and how they will interact near New England. It looked like this first storm initially was going to ride out to see, but the latest trend has this low tracking westward and closer to the coast. Does that sound familiar? That is exactly what happened with our Friday snow! So we need to watch this storm closely for Monday. Today, it appears this storm could track close enough to us that snow will develop late Monday and continue Monday night into Tuesday. Will this be a glancing blow of light accumulating snow or something more significant? It remains to be seen. If this low track any further westward we could be dealing with a more significant storm to start the week. For now, we have a glancing blow and a chance of a few inches of snow Monday night through early Tuesday morning. Could this impact the NH Primary? Absolutely. We see how quickly things can change. For now, I am cautiously optimistic for Tuesday with Light snow in the forecast, but not enough to cause any big problems or delays that could affect voting turn out. We'll see.
Another batch of energy will follow in behind this departing storm, which could provide enough lift and instability to create an inverted trough to trigger a few more scattered snow showers late Tuesday into Wednesday. Behind all of this is a colder pattern which will last right into next weekend. So moral of the story here is, expect more changes to the forecast. Monday, Tuesday and Wednesday are the prime days for our best chance of some accumulating snow fall. The winter pattern has been re-energized for now so we will have to remain on our toes for this slight, but quick changes which can have big impacts on a forecast.
