The weather over central New York the next couple of days will be relatively quiet. High pressure will build east from the Midwest and bring us seasonably cool air by middle of January standards. The weather over us will be dry for Tuesday and there could even be some sun.
High pressure shifts east into New England on Wednesday. While this system will still be the major fact in our weather, we will be watching a stalled front well to our south stretching from the Mid Atlantic into the Southeastern United States. This is the same front that brought an end to our January Thaw earlier Monday. Later Tuesday into Wednesday a wave of low pressure will ride northeast along the front. There will be a shield of light snow and flurries to the north of this low and it looks like some of this precipitation could graze parts of the southern Tier Wednesday. We expect little if any accumulation of snow.
Once Wednesday’s low tracks east off into the Atlantic, 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 central New York during the day Thursday. This front will be accompanied by flurries and even some squalls and it is quite possible our temperatures will fall through the 20s during the day.
The first batch of arctic air, however, will be fleeting. By Friday afternoon, the arctic air will be pulling out of central New York. This will allow our temperatures to moderate and we could be above freezing by Saturday. However, a new surge of cold 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.
