With high pressure once again setting up shop in the region we can look for lots of sunshine, continued below normal temperatures and moderate to light winds through Wednesday. It will be particularly cold tonight and Tuesday night as some locations will likely dip just below zero.
Tuesday will be very similar to Monday’s weather with a good amount of sunshine, a brisk breeze and below normal temperatures. Readings may actually run 3 to 5 degrees below those of today as another surge of colder air overspreads the area.
Over the next few days low pressure will ripple along the Gulf of Mexico Coast. This will bring precipitation across the southern tier of states where some areas will see ice and snow from this system. You will probably hear much about the impacts of this storm in the south over the next couple of days. This will be a disruptive storm from the deep south into the mid-Atlantic and eventually southern New England this week.Winter Storm Watches have already been issued as far north as central New Jersey and there is no doubt those watches will be extended northward into southern New England over time.
The low will emerge off the coast of South Carolina early Wednesday and then it is expected to set its sights on southern New England. By Thursday morning the low center is forecast to be near Virginia Beach as it continues to move northeastward. There is high confidence that we are going to have impacts from this storm but the storm track remains somewhat in question. Current thinking is a track anywhere from across outer Cape Cod to just southeast of Nantucket Island. Some of the models are suggesting a deepening and impressive storm that may bring heavy snow, high winds and some minor coastal flooding. Although there remains some question whether a mix or even change to rain occurs along the coast and southeast Massachusetts that will probably not be an issue for the Pioneer Valley where all snow appears to be in the cards. If all goes as planned the storm should begin to move out of here early on Valentine’s Day.
The timing of the onset of precipitation is after midnight on Wednesday night, early Thursday morning if you will, then ramping up during Thursday morning and continuing all day into Thursday night. With that said commuters will have another trying time getting to and returning from work, schools may close and municipalities will have to dig deeper to fight another winter storm. It has been a winter checkered with nasty cold and significant snows for our area and no end is yet in sight for the short term. We could see another light event over the weekend, then possibly something bigger for next week.
