Synopsis: An Arctic front moves through with snow showers and squalls tonight. Very cold air behind the front moves in for Thursday and Friday. A winter storm will affect the state this weekend followed by more Arctic air next week.
An Arctic front, currently over Pennsylvania and upstate New York has a line of snow showers and squalls associated with it. Although the actual line of precipitation is narrow, it was heavy at times. This combined with the very cold ground should yield a quick period of accumulating snow. Accumulations, however, should be relatively light, because of the fast movement and narrow nature of the squalls. My thinking right now is that most places will get less than an inch of snow, but up to two inches is possible in two areas: the Litchfield Hills, and also across far Eastern Connecticut, where some coastal enhancement may occur.
The next two days will be very cold. Tomorrow morning’s temperatures will be in the single digits in the North and teens in the South. They will basically hold steady all day. Another band of snow showers is possible later in the afternoon, but most accumulations with this band should be restricted to the Litchfield Hills and be less than an inch. The real story tomorrow and Friday will be the cold and wind. Tomorrow night’s low temperatures will be below zero everywhere, except near zero in the urban centers along the South Coast, such as Bridgeport and New Haven. Combine this with a gusty wind, with gusts up to 35-40 MPH, and wind chills will be -15 on the South Coast to -30 in the Litchfield Hills. Anyone who has to spend a significant time outside working or walking should cover any exposed flesh and dress appropriately. Here's a look at forecast wind chills from the 0z GFS model.
Here's a look at the various parts of the system on the GFS model.
Yet another Arctic air mass will overspread the state to start the next week, though temperatures probably won’t be as cold as what we have just seen, partly due to the fact that we are approaching March. There are some hints of a potential coastal storm somewhere around Tuesday or Wednesday, but right now, most indications are that most of the effects of this storm stay South of the area. However, being this far out in time, it is way too early to say definitively one way or the other.
