NH1 Weather Insider with Joe Joyce: It's going to be really nice midweek in NH

NH1 Weather Insider with Joe Joyce: March 29, 2016 | NH1

Well, this is more like it! High pressure slides towards the Mid-Atlantic states with more sunshine and lighter winds for the midweek. High temperatures will climb into the mid-upper 50's during the afternoon. A definite milder feel to the afternoon for being outside and soaking up some early April sunshine! As the high pulls farther south, a milder SW wind will develop Thursday. Winds will be picking up and these milder breezy winds will push afternoon temperatures into the 60's to near 70 with sunny to partly sunny skies by afternoon. Winds could gust upto to 30 mph.The upper level ridge will hold on long enough across the eastern sea board to keep most of Thursday mild and dry.

We will be watching a low form the midwestern states track up through the Great Lakes. This will push a cold front across New England Friday. Light Showers will develop during the pre dawn hours of Friday, with the potential for some heavier rain along this cold front Friday during the afternoon along with some gusty winds.

Even though Friday will be mild in the 60's, The break down of the unseasonal warmth begins with the rain, but the weekend is where the cooler air will be arriving. The weekend will feature an Arctic cold front, which will deliver an unseasonably cold airmass for early April right from the Arctic into New England. Saturday will be a mix of sun and clouds with a west wind with highs in the Lwr 50's. A weak upper level low will push through, and bring just enough instability to trigger a brief pop up shower or snow shower later in the day. But the main action will come Saturday night as a Clipper low will track across the North country and rapidly deepen. It will push an Arctic cold front through and off the coast early Sunday morning. An intense band of snow showers or squalls will develop with this passing low in the mountains.

Breezy NW winds and cold air advection will help to keep temps in the 30's to near 40 degrees Sunday with a mix of sun and clouds. Another cold front pushes through late Sunday, and this is where temperatures will really drop off! Once the sun sets Sunday night, lows will drop into the teens overnight with some areas approaching record cold early Monday morning. I would hope no one here in New Hampshire has started any early gardening, since it is way too early for that...but if you have any potted plants...Sunday Night you will definitely want to bring them indoors. The cold will stick around through Monday with sunshine and unseasonally cool temperatures. Highs will remain in the 30's to near 40 when typically we should be closer to 50 for early April.

Another low may track towards the mid-Atlantic states and off the coast coming with a period of light snow Monday night and ealy Tuesday morning. It looks fast enough to prevent much if any accumulation. This low will reinforce a NE wind and lock in the low level cold with temps remaining in the 30's to near 40 into Tuesday.

The trough that supplies the cold blast of air will begin to lift out next week. So it does not appear this blast of Arctic air will not have much staying power without much of a blocking pattern to hold that trough in place. Temperature fluctuations will continue in this early Spring season with another shot of cooler air coming sometime around April 9th...again...the cold is fleeting. In fact it may get cut off at the pass and never get in fully in here. While the cooler air will make for a temporary set back with one step back...this time of year is definitely two steps forward! Give this winter a kiss good bye! But keep the jackets handy!
