On this morning’s weather map, a frontal boundary is draped to our south and west from Pennsylvania west through the mid-section of the country with an area of high pressure centered north of Lake Ontario. This high is forecast to move east and off the New England coast by tomorrow. In doing so, it should help give the region some sun, though it may be a slow process with much the region waiting until afternoon.
Thereafter and over the next 24 hours, the aforementioned frontal boundary will retreat northeast as a warm front, the leading edge to warmer air. As this moves through the region late tonight, a few showers may impact the area. Once the front clear the region, brisk south to southwest winds will import unseasonably warm air into Central New York. In fact, high temperatures tomorrow will soar well into the 60s…and with enough sun we may challenge the record high for the day which is 68° set in 1941.
Later in the day the threat for rain will increase as a cold front closes in on the region. The air behind the front will be much colder as well fall back closer to normal values. The colder air moving over Lake Ontario will likely induce lake effect snow showers. Winds are forecast to be northwesterly; therefore lake effect snow showers appear to be most likely southeast of Lake Ontario, including the Syracuse area. High pressure is forecast to build into the region Thursday allowing for more in the way of sunshine.
Looking ahead to the weekend, complex frontal boundaries are forecast to sag east and south. This will increase cloud coverage as well as the threat for at least a few showers. Right now, details are still iffy as computer models are offering different outcomes. We should have a better idea on what the weekend may hold later on this week.
