Low Rain Chances Tuesday
A cold front will slide through the Finger Lakes Tuesday afternoon. However, the front will be weak and will get little help from the atmosphere, resulting in only a few scattered showers.
There is a break in the cloud cover between the front and a disturbance over southern New England across the Finger Lakes this morning. Sunshine and quickly warming temperatures will be the rule this morning as a result, though some early clouds will linger over the eastern Finger Lakes.
Temperatures should warm to around 80 degrees by the early and mid afternoon hours.
Fair weather cumulus clouds should start to develop by the late morning and will become numerous this afternoon. As the front moves in, a few showers will start to develop.
Most areas will probably see very little to no rain today, even with the front moving through. A few rumbles of thunder will be possible with any of the showers that do manage to develop, but severe thunderstorms are not expected.
Precipitation should quickly die off this evening as the sun sets and the daytime heating is lost. High pressure will also start to build in behind the front.
Mild Wednesday, Warmer Beyond
With north winds ahead of the high pressure system, some low-level moisture may be trapped over the Finger Lakes Wednesday morning. This may result in some morning clouds and even a stray shower or two.
Dry air should work in and erode the clouds by the midday hours. The afternoon should be sun filled.
Temperatures will be a touch cooler with the north winds behind the cold front, but highs should still reach the mid 70s.
Temperatures should be warmer thereafter, with highs at or above 80 degrees for the rest of the week and into the weekend.
The chances for rain are looking less on Thursday, but at least scattered showers and thunderstorms are still likely on Friday.
A shower cannot be ruled out this weekend, but most of the time should be partly cloudy and dry. The same currently goes for Monday during the eclipse, but it is certainly too early to count on the weather one way or the other for that.
