The weather in the short term here in central New York, and for that matter the whole Northeast, will be dominated by a large area of high pressure. We’ve been talking about this system for several days now. The center of this system is currently over Virginia and it will slowly slide east during the next 24 hours. This means not only will we have the sun to warm us the next couple of days but a southwesterly wind will import warmer air into central New York as well. We expect well above normal temperatures through Friday.
As we head into the weekend we have a couple systems that will impact weather. First, a cold front will drop south into New York State for Saturday. Meanwhile, on the western end of the cold front an area of low pressure will form. This low will track northeast from the Ohio Valley on Friday to a point just to our northwest by Saturday. The combination of this low and the cold front will mean we finally get the chance for some showers and thunderstorms on Saturday. As low pressure starts to pull north into Canada Sunday we will be left with cooler and showery weather.
Following our unsettled weather over the weekend, high pressure will build back into central New York for Monday and at least part of Tuesday.
