A weak disturbance will drop southeast into the Finger Lakes from the Upper Great Lakes late this afternoon and remain stalled out over the region into Saturday.
As this disturbance moves into our area, it should interact with the daytime heating to pop a few areas of showers and maybe a thunderstorm. There are some questions as to how widespread the activity may be, but I think a fair amount of the area will probably not see much rain.
Most of the precipitation should dissipate as the sun sets this evening, but a few showers may continue overnight. On Saturday, the focus for precipitation may shift to the south, but at least a chance for a few showers or storms will continue.
The disturbance will then dissipate and cease to be a concern for our weather. Instead, high pressure will take control. Centered to our south and then southeast, this high will put our region in a southwest flow of increasingly warm air. Temperatures on Sunday and Monday will rise well into the 80s.
The next substantial chance for rain after this disturbance will come on Tuesday.
