NH1 First Alert Weather: Sunshine's Back!
National Weather Service Text Product Display High pressure will build in for Thursday. A few clouds with some patchy fog may start the day, but as the sun warms the ground skies will clear. Look for increasing sunshine Thursday with high climbing into the lwr-mid 50's by afternoon. A few areas may climb into the upper 50s across southern New Hampshire. Along the Canadian border, upslope flow will keep some clouds through the morning. Skies will be mostly clear and cooler air will settle in overnight with lows near freezing in colder spots.
High pressure moving in from the west will crest overhead Friday and Saturday thanks to a high-amplitude pattern where we are lucky enough to be in the under the ridge just in time for the weekend! The result will be a couple of really nice days with highs above normal with highs nearing 60. Onshore winds will return Saturday afternoon and could result in cooler temperatures and some stratus, especially on the coast thank to a low parked far off the coast.
Things begin to change Saturday night as the overall blocking pattern begins to move eastward. The result will likely be moistening onshore flow and the potential for low clouds and drizzle later Saturday night. An upper level low pressure then takes over as it digs down through the Great Lakes...eventually forcing surface low pressure to move across New England Sunday. This will likely mean a dose of rain during the midday or afternoon. Timing of showers is still to be determined. Thereafter, cold air wraps back in as the upper level low is slow to move, which could result in snow showers Sunday night and Monday, across our northern mountains. There is some disagreement on how long the low lingers, but it could indeed linger through early Tue resulting in building clouds and maybe even a spotty shower through that time. Breezy NW winds will deliver and unseasonal cool shot of air Monday, Tuesday and Wednesday with highs in the Lwr-mid 40's.
