A system that impacted us late last weekend will have a role in our weather come midweek. A cold front came through central New York Sunday night but for the last day or so, this front has been stalled over the Southeastern United States. Low pressure is just now forming in Georgia along this front and will track northeast over the next 24 hours. Although the actual low will track well to the south of central New York, the shield of precipitation associated with the low will extend well to the north. Our computer models are coming into better focus in bringing the northern edge of this precipitation (a steady area of light snow) into central New York tomorrow. The snow will be steadiest from mid morning through mid afternoon with the greatest accumulations of snow as you head south toward the Pennsylvania border. As low pressure moves off the coast later in the day, the snow will begin to wind down.
Once the low tracks east off into the Atlantic tomorrow, our focus will shift to the arrival of a shot of arctic air. The leading edge to this colder air will be a cold front that will move through the region during the day Thursday. Even though we have a high temperature near 30 degrees it looks like that will be reached early in the day. Our temperatures are likely to drop through the 20s. While we do expect some snow with this change to colder weather, at this point, it doesn’t look like we would see anything significant.
The first batch of arctic air won’t last long. By Friday afternoon, the arctic air will be pulling out of Central New York. Winds turning into the southwest by Saturday will mean even milder air to star the weekend. We could be near 40 degrees to start the weekend.
Even while we are briefly warming, a new surge of arctic air will be pooling over southern Canada early in the weekend and will dive southeast and mean a change in our weather before the end of the weekend. Early indications point to the change occurring sometime on Sunday as low pressure and a second arctic cold front close in on the region. Again, it’s early but if current indications hold, Sunday may very well be a day of transition to bitterly cold air (the coldest of the season) that may be with us much of next week.
