Late Friday-Early Saturday
For the most part, the weather over the weekend and even through next week looks rather tranquil. There will be a few chances for rain or even thunderstorms, though.
The Finger Lakes is sandwiched between boundaries this morning, with unsettled weather across Pennsylvania and the Mid-Atlantic and a second boundary stretching west to east across the northern Great Lakes.
These two areas of disturbed weather will not move much today but will slowly squeeze toward the Finger Lakes. Most areas will remain dry through the daytime hours, but a few scattered showers will pop up late.
The most likely area for rain will be in the higher elevations to the west, stretching from areas west of Penn Yan and south of Canandaigua back toward Jamestown. A late shower near the shore of Lake Ontario will also be possible.
Otherwise, expect a mix of sun and clouds with similar temperatures to yesterday around or a bit above 80. Humidity levels will remain comfortable, but dewpoints will rise late this afternoon and evening and should sneak back into the 60s.
Overnight, the northern boundary will drop south through the region. Showers will be scattered about the region, especially after midnight and continuing into the early morning hours Saturday. The rain will be light, and a few areas will probably miss out on the showers altogether.
The rest of Saturday should have gradually increasing sunshine. Temperatures will start the day in the low 60s and rise to a high around 80 degrees. Dewpoints will drop behind the boundary, returning to the 50s by the early afternoon.
Another weak system will slowly make its way through the area Sunday and Monday.
The chances for widespread thunderstorms on Sunday have declined. A few showers will be possible, with a couple afternoon thunderstorms scattered about the western half of the region. Probably less than half of the area will see rain on Sunday.
Temperatures on Sunday will depend on how the clouds and showers evolve but should range from mid 70s in higher elevations and the Southern Tier to low 80s along the Thruway.
On Monday, the situation flips with scattered showers and storms mainly over the eastern half of the region. At this point, the greatest concentration of thunderstorms appears over eastern New York, though.
Cooler air will start to wrap in on the backside of the system, keeping highs in the mid 70s throughout the region.
A few lingering showers may be possible on Tuesday, but most areas will probably not see any rain. Highs will be in the low 70s.
Temperatures will bottom out on Wednesday, but the expected highs are moderating upwards. What looked like 60s the last couple days is now trending toward at least reaching 70 degrees.
Dry weather should continue Thursday and probably through Friday at least. Temperatures will climb, with mid 70s Thursday and highs near 80 Friday.
