An area of low pressure tracking northeast from Ohio will spread some rain showers into the Finger Lakes by Tuesday afternoon.
This low pressure is the weaker of a pair of systems. The second, stronger part of this complex is moving along the east coast and will head out over the Atlantic Ocean with no direct impact on the Finger Lakes.
The part that will impact our region will start to do so by this afternoon as it slowly drifts northeast. Widespread showers accompany this area of low pressure. A few showers will be possible this morning, especially across the southwestern parts of the area.
By the afternoon, showers should overspread the remainder of the Finger Lakes and continue into the evening. The steadiest showers will likely be during the first few hours after sunset. Showers will persist overnight and into the morning hours on Wednesday, though by then, they will be much more scattered. By Wednesday afternoon, the region should be dry.
Temperatures will be warmest today across the southeastern parts of the Finger Lakes, where some warm air will sneak in ahead of the low. Temperatures may reach the upper 50s for places like Elmira, Binghamton and Ithaca. In contrast, temperatures will only be in the low 50s for the northwest parts of the region, including Rochester and Canadaigua.
Overnight lows will generally be in the mid and upper 40s with plenty of clouds and showers around. Wednesday will be a bit cooler, with mostly low and mid 50s.
A new storm system will move in on Thursday with more showers. Scattered precipitation will be possible Friday and into Saturday, with some of the rain possibly mixing with snow Friday evening into Saturday morning.
