NH1 Weather Insider with Joe Joyce: NH is stuck in a rut
NH1 Chief Meteorologist
A few scattered rain and snow showers pushed through overnight as weak wave of low pressure tracked along a stalled front lying across New Hampshire. Some northern ski slopes may wake up to a few new inches of snow. Warmer air is building to our south and wants to shift northeast. Colder air is pushing south and which wants to push into the Northeast. These two airmasses are on a collision course and have hit an impasse right over our heads today!
This boundary separating these two airmasses will be sitting right over us the next few days bring periods of unsettled wet and even snowy weather at times. The cold front will sit right over us Wednesday with cloudy skies. SNH should be on the milder side of the front in the 50's, but northern NH will be in the 40's during the afternoon. The cold front will push into Southern New England tonight with colder air continuing to settle into the region. By midnight, our next wave of moisture will be arriving.
Snow will develop during the early morning hours of Thursday. Light coatings to 2" will be possible by the Thursday morning commute across northern and central New Hampshire. Warmer air aloft will start to mix the snow to sleet and freezing rain Thursday morning. The snow/rain line will advance into the north country. There is a concern for some cold air damming with areas of freezing rain or freezing drizzle leftover into Thursday afternooon. Highs on Thursday will only be in the 30's and Lwr 40's. By Later Thursday, some areas across the far north country have the potential for seeing up to 6" of snow total in the next 2 days.
Another wave of low pressure will track from the Great Lakes into New England for another period of rain late Thursday night into Friday morning. I expect Friday afternoon to be drying out. This Low will come with a surge of milder air right into New England with temps climbing back into the the 50's, and 60's farther south.
High pressure will settle in for Easter weekend. Sunshine Saturday in the 40's. Skies will be sunny to partly sunny and warmer Easter Sunday in the 50's with SW winds. Another chance of rain showers by next Monday. There remain questions whether this will be a weak cold front passage with a few showers, or a stronger storm with heavier rain, and the potential for snow in the mountains. Stay tuned to the forecast on NH1 news as these changes will be coming fast and furious. Plenty of weather to watch!
