NH1 Weather Insider with Joe Joyce: Tuesday March 1, 2016
NH1 Chief Meteorologist
Happy Meteorological Spring! The three coldest months of the year are behind us now. We have made it through the worst part of the year where Mother Nature has a history of throwing some pretty challenging weather at us. Not this time around! We have only receive about 24" of snow so far the season. The typical average is closer to 60". Plus, this winter will go down as the warmest winter on record for Concord, NH. When you add up the three months we just went through, it is not surprising! Enjoy it because most winters are not so easy!
Tuesday will have weak high pressure providing plenty of sunshine and a slightly cooler more seasonal airmass. Highs will be in the Lwr 40's by afternoon across southern NH, and 30's across the the mountains and lakes. Temperatures will cool off tonight into the 20's as we track of a batch of precipitation which will be arriving at the coldest part of the day..late at night. A wave of low pressure will track from the Ohio Valley right into northern New England. A burst of snow and sleet will develop around midnight or shortly after. There will be a quick change to rain across SNH, with colder air holding on longer in the valleys where sleet and freezing rain will be an issue during the pre-dawn hours. The cold air will be deeper across the north country where there will be a solid thump of snow on the front end across Northern New Hampshire, especially in the mountains where up to 3-6" of snow will fall and a lighter snowfall for lower elevations with a general 1-3".
As the low approaches, a warm front will be lifting northward during the early morning predawn hours Wednesday. A snow rain line will be advancing quickly into the North country. Freezing rain may hold tight in interior valleys at dawn. Temperatures will be rising overnight along with the passage of the warm front into the 40's. Most of us will be dealing with a very wet and rainy Wednesday morning with the potential for some heavier downpours during the morning commute. Even in the mountains, snow will be changing to sleet and rain. As the low begins to pull away, we will be seeing the rain tapering off quickly during the afternoon. The may be a change over back to snow showers across the northern mountains once winds shift back to the NW and direct cooler air into the region. Breezy NW winds will direct the colder air back into New Hampshire. After briefly reaching the upper 40's and Lwr 50's across the Seacoast during the morning..once the rain ends and the storm pulls away, expect temperatures to be in a steady decline with the setting sun.
A much colder day on Thursday with high pressure from Canada, along with lighter winds and sunshine. Highs will only be in the 20's and some lwr 30's. It will be a colder and dry end to the week. The will be a storm trying to gather close enough to New England to spread in some snow Friday...but at this point it looks like it will ride far enough away from New England to spare any big storm. Another day of computer models will install a bit more confidence. I do expect more clouds on Friday because of the proximity of this low, along with temperatures starting off in the single digits!
The weekend this far out looks great with sunshine and highs in the 30's and Lwr 40's by Sunday. Longer range weather forecast does not look too cold or snowy either. Is this winter cooked? It sure seems that way....not much more time left!
