Unsettled this morning

As advertised yesterday, there is a bit of wintry precipitation around this morning.  Milder air returns tomorrow.

Today:  Any mixed precipitation south of Concord, NH changes to rain by 11 AM, snow/sleet mix continues north into the early afternoon.  Rain/mix should taper off by mid afternoon.  Highs in the low to mid 40s south, mid and upper 30s north.

Tonight:  Decreasing clouds, lows in the mid 20s north, low to mid 30s south.

Tomorrow:  Bright sunshine, warm, highs 55-60 south(cooler along the coast), upper 40s to low 50s north.

Tomorrow night:  Becoming partly to mostly cloudy, lows upper 30s to low 40s south, 30s north.

Friday:  Chance of a rain shower, mainly in the morning, highs in the low to mid 60s south, 50s north.

Discussion:

A few changes, rather improvements, to the forecast this morning.  One, the majority of the precipitation today will be to the south which will prevent hardly any accumulating snow across Northern and Central New England.  Good for most, bad for others, skiers who wanted to keep the season going.  Second is the forecast for the weekend.  What looked like it was going to be a messy Friday and Saturday, doesn't look as bad this morning.

So for today, a low pressure system is blasting through the region.  Eventually most locations will change over to rain, a few spots north getting stuck with all snow or a snow/sleet mix.  Little or no accumulation expected.  Most of the precipitation will be clear by 2 PM in Southern New England, 4 PM Northern New England.  Our skies will clear overnight tonight but temperatures won't plummet overnight as warm air will already be moving in overhead.

This warm up aloft will push temperatures up and up tomorrow and Friday.  Thursday will be the nicest looking day where Friday will be the warmer of the two days.  Friday morning there will be a weak frontal system that will push through the region that could set off a few scattered showers, mainly during the morning.  After that clears we should see periods of sunshine and temperatures climbing into the 60s for Southern New England, upper 50s to the north.  Eventually this frontal passage will bring a crash in our temperatures as this weekend will be much cooler.  Highs should generally be in the 40s for both Saturday and Sunday and we should be relatively dry.  There is a slight chance of a rain or snow shower on Saturday morning with a secondary front that will push through, helping to usher in that cold air.  After that, high pressure will take over a few days, bringing plenty of sunshine.  Monday will probably be the coolest days where daytime highs might be stuck in the 30s.
