NH1 Weather Insider with Joe Joyce: February 4, 2016
NH1 Chief Meteorologist
A cold front is pushing off the coast Thursday. Lingering low clouds will start the day with the front hugging the coast at dawn. Even a few light showers are possible in Southern New England early. Clouds will be giving way to partly sunny skies today thanks to drying breezy west winds. Temperatures will be starting off the day mild in the 40's and Lwr 50's. Temperatures will remain mild and steady from most of the day with highs reaching 50-55 across southern New Hampshire. Another gorgeous spring-like day for early February.
The cold front will stall off the coast and a wave of low pressure will be tracking northward along the front. Clouds will increase Thursday night as this low tracks up the coast. Upper level winds with a trough in the Northeast could kink just enough that by early Friday, a shield of accumulating snow will be clipping SE MA from Cape Cod to Boston. Clouds will have advanced and thicken over us Friday morning. We may even see a few flurries at the coast. Cooler NNW winds will be in place Friday as the low pulls away. Highs will be the 30's with a more wintry feel to the air. Skies will brighten during the afternoon to partly sunny skies.
High pressure SSW of New England Saturday will wrap in a slightly milder flow for Saturday with highs back to near 40-45. Skies will be bright with Sunny to Partly sunny skies. I expect a few clouds to increase ahead of a weak cold front which will push through Late Saturday night and early Sunday. We may even see a few snow showers early Sunday morning across the northern mountains. NW winds will return n Sunday with increasing sunshine and building high pressure from Canada. This will bring in colder air for Sunday night through Monday with highs dropping back into the Lwr 30's to start next week.
All eyes are focused on a deep digging trough across the eastern US during the start of the week. Energy will pile into the the trough which will help to trigger some storm development off the coast. One piece of energy (low pressure) will be directed far enough away and south to keep Monday dry. It is the second piece of energy which will be directed up the coast and could turn into a snow storm Tuesday. Of course, this far there are more questions than answers...so details are extremely sketchy. How much moisture, how strong, the track, the temperatures, the timing, are all questions we will be trying to determine in the coming days. It is definitely in the realm of possibility that Tuesday will see snowy conditions on the roads, so this may have an impact on the New Hampshire Primary....but again, we know how simple changes can dramatically alter a forecast. So we will keep our eye on it. If I had to make a guess right now I would say the snow will be arriving early Tuesday morning and winding down during the afternoon. I general 3-6+" snowfall can be expected. It will be a quick mover. It will mark the beginning of a colder wintry pattern which will take us through the 15th. Believe it or not, but after February 15th...it does not look tremendously cold.
