They say that things happen in threes, and sure enough, the third coastal storm so far this month is set to rapidly intensify off the East Coast over the next 24 hours. Unlike the first two, however, this one will not be a direct hit for Pennsylvania and New Jersey, but instead offer a glancing shot of a little light rain and snow late Monday and Monday night that will linger into early Tuesday morning. Eastern New England will bear the brunt of storm number three, which could bring over a foot of snow from Massachusetts to Maine as we are spared any significant snow accumulations. Still, a coating to an inch or two of snow is possible for most, as we live on the outer fringes of our further offshore ocean storm, with brisk winds and colder than average temperatures persisting through most of the week following the storm's departure.
After some early-morning sunshine Monday and a cold start with temperatures well down into the 20s and even some teens in the Poconos, clouds have begun to thicken and will continue to do so through the rest of the day. While most of the day remains dry, there could be a little light rain and snow developing later in the day, even though most of the precipitation will be delayed into the overnight hours and early Tuesday morning. With high temperatures around or a bit above 40 degrees Monday, any light snow that does manage to develop later Monday or early Monday evening will have a difficult time accumulating, due to the light nature of the snow and the above freezing temperatures. Daytime snow accumulation later in March is difficult to begin with, even more so given the above factors.
Overnight, expect some intermittent light rain and snow to become all snow, with breezes increasing as our ocean storm strengthens. Lows will drop to around the freezing mark, and the colder temperatures plus the loss of daylight should allow for some minor snow accumulations for most of us. Even at night, unpaved surfaces like grass, trees, and cars will likely be able to more readily accumulate snow than roadways, but some slick spots are possible on untreated roads. However, many roads may just remain wet.
With the steadier snow shield remaining well offshore to our east, only a coating to an inch or two of snow is expected, although a few places in the northern Poconos or northwestern New Jersey could see more than two inches of snow. Snowfall totals should gradually increase the farther north and east you travel, and winter weather advisories are posted from Northampton, Monroe, and Pike counties on east through northwestern New Jersey overnight into early Tuesday. It is these areas that may briefly get into some steadier light snow on the outer fringes of our coastal storm early Tuesday. Northerly breezes will become rather brisk and blow around 10 to 20 miles-per-hour overnight.
While spring is officially just over one week away, the middle of this week will be characterized by blustery winds, unseasonably chilly temperatures, and occasional snow showers and flurries. While no significant accumulation is expected and we should manage at least some sunshine each day, high temperatures won't do much better than 40 degrees each afternoon from Tuesday through Thursday, and west to northwest winds will remain persistently brisk around 10 to 25 miles-per-hour with higher gusts. That means wind chills will remain below freezing much of the time through midweek. Our average high for mid-March should be rising through the mid to upper 40s, so we'll remain well below that figure over the next four days before some milder air may finally make progress in our direction by week's end.
We should finally be able to shut off any mention of snowflakes by Friday, although the brisk and cool weather will linger through the end of the week. The weekend has milder or at least less cool prospects as highs climb higher into the 40s on Saturday and then finally reach 50 degrees Sunday. Some rain may eventually follow early next week.
Spring officially begins next Tuesday March 20th at 12:15 p.m. with the arrival of the vernal equinox. We took a step in the spring direction this past weekend as we sprung ahead our clocks back to daylight saving time. Presuming you made the switch, you then enjoyed the first of many post 7 p.m. sunsets last night.
