Low pressure, the remains of Hurricane Sandy, will move north into Western New York this afternoon and eventually Canada over the next 24 hours.
Consequently, with the low near us there will not be much in the way of pressure gradient (or change in air pressure over distance), and the existence of pressure gradient often is the cause for wind. However, the low pressure system will provide plenty of clouds and the threat for passing showers.
As the low moves into Canada Thursday, that will put us on the backside of the storm with a shift in winds into the west-northwest for the end of the week. Even though the center will be well to our northeast by Friday, the circulation of the storm is large and we will continue to see showers...and probably a greater threat.
The northwest winds will bring gradually colder air into Central New York. In fact for Friday into Saturday, our high temperatures will be 10 degrees below normal for early November. That brings up the possibility of some snow mixing in with the rain showers over higher elevations Friday and perhaps even the lower elevations Saturday morning. Below average temperatures are expected into early next week along with mainly dry weather.
