NH1 Weather Insider with Joe Joyce: Light wintry mix, icy spots develop
NH1 Chief Meteorologist
Some of us are waking up to light snow showers this morning. The precipitation should not be heavy enough to cause any big problems for the morning commute. Light coatings of snow will be possible from Concord North. Once you get north of the Lakes there will be a better chance of seeing 1-3" of snow accumulate during the morning hours, especially in the higher elevations. A backdoor front pushed through Wednesday and we are on the colder side of the front today. NE winds from Canadian high pressure are supplying low level cold, so high temperatures will not be able to get out of the 30's today. A cool raw feel to the air. Snow showers will be shifting north during the late morning and midday. A quieter afternoon can be expected with cloudy skies and the potential for a few scattered showers or a light persistent drizzle with the onshore winds locking in the low clouds. Meanwhile, across the north, cold air will be locked in place in the valleys and foothills. Snow will change to sleet or pockets of freezing rain or freezing drizzle continue during the afternoon.
The backdoor front will move back towards us as a warm front Thursday night. We will remain on the colder side of the front with the cold locked in down at the ground. Areas of freezing drizzle will be an issue during the evening hours before changing to showers overnight as the warm front pushes through and warms up even the low levels with a wind shift to the south, southwest. Again, across the northern mountains and foothills the cold will be slower to depart, so Thursday night into Friday morning could have a light coating of ice in the colder surfaces like trees, cars and sidewalks. A wave of low pressure will track through northern New England Friday. Milder SW winds ahead of the low will pump temps back into the 50's. Periodic rain and drizzle can be expected Friday, with hopefully a somewhat drier afternoon. Some models are hinting at the showers lingering into the afternoon with a slower passage of a cold front. There will be a few brief downpours.
As the low pulls away, High pressure returns to save the day and delivers a nice weekend! Saturday will be beautiful with sunshine and highs in the Lwr-mid 50's. A cooler onshore wind will keep temps in the 40's at the coastline. Easter Sunday will feature a warmer SW wind with highs climbing into the 50's and Lwr 60's by the afternoon. Some rain is expected to arrive on Monday, with drier weather arriving for Tuesday and Wednesday.
