Rain Moves in from the South

The chances for rain will increase across the Finger Lakes late today as a disturbance traveling along the jet stream pushes in.

Most of the daytime hours should be quiet and dry across the Finger Lakes. However, a few stray showers cannot be ruled out at almost any time.

Outside of the showers, skies will be a mix of clouds and some sun. Temperatures will top out within a couple degrees on either side of 80. Dewpoints will be muggy in the mid and upper 60s.

Rain and thunderstorms will develop this evening, starting with the Southern Tier and spreading north. Some of this activity could start popping up as early as 4 or 5 PM near the NY-PA state line.

Precipitation should become more widespread this evening. Rainfall amounts will vary greatly due to embedded downpours. A few areas will probably be missed altogether while others see an inch or more of rain.

Flash flooding and severe thunderstorms are not expected. One or two stronger wind gusts will be possible in the Southern Tier for any storms that develop before sunset.

On and off rain will continue through the night and into early Friday before tapering off.

Weekend Rain and Temperatures

The chances for rain will never completely leave on Friday. After the morning showers taper off, new development seems likely in the afternoon.

These will be scattered showers and storms that will again continue into the evening. Not everyone will see this rain since it will be scattered.

Saturday may also have a few scattered showers and storms. The chances for rain seem higher to the north and east of the Finger Lakes though. Sunday, at this point in time, looks dry.

Temperatures will be held in the upper 70s on Friday but will increase thereafter. Expect low and mid 80s on Saturday with mid and upper 80s on Sunday. Dewpoints will be in the 60s, making it feel muggy but not oppressively humid.

Monday and Tuesday will become increasingly hot with 90s possible both days. Some thunderstorms may be possible late Tuesday as a cold front approaches.
