What to expect from the weather Sunday in the Finger Lakes


finger lakes weather forecast sunday october 15 2017 rain wind cold front
Much of Sunday will be breezy, but warm and at least partly sunny. Late in the day, a band of rain and wind will plow through the region.


Sunny, Warm, and Breezy

Much of Sunday will be rather nice across the Finger Lakes, albeit a bit on the breezy side.

A strong area of low pressure over the Upper Great Lakes will pump warm air north into the Finger Lakes.

The associated warm front with this system is already north of the region, so nothing more than a very isolated, brief spit of rain is expected this morning.

Instead, skies will be a mix of sun and clouds, with more sun in the morning and gradually increasing cloudiness later in the afternoon.

Temperatures will soar this afternoon, topping out in the mid and upper 70s for most of the Finger Lakes.

Winds will increase this morning and be gusty into the afternoon. Top gusts through the mid-afternoon will be in the 35-40 mph range for most areas.

Cold Front Brings Band of Rain, Wind

Low pressure will continue to push northeast through the day. As the storm continues into Canada, it will drag a cold front through the Finger Lakes late this afternoon and evening.

Along the cold front, a narrow band of heavy rain will develop. A few claps of thunder may be possible as well.

A band of heavy rain and strong winds will cross the Finger Lakes tonight between 5-8 pm. Click to enlarge.

Since the band will be narrow and fast moving, precipitation amounts will remain low. For a brief time though, it will rain very hard and could make travel hazardous.

Even stronger winds are likely along and just behind the band of rain.

Gusts of 40-50 mph should be commonplace, especially over higher elevations, in the hour or so just after the frontal passage.

This band should enter the western Finger Lakes around 5 pm tonight and should be east of the area shortly after 8 pm.

Temperatures Crash Behind Front

Since the front is expected to arrive near or after sunset, temperatures will already be declining as the front moves through.

As the front passes, a very quick 5-10 degree drop is expected before a slower, but steady drop.

By midnight tonight, 40s will already be showing up over the western Finger Lakes.

Mid and low 40s are likely by Monday morning, with a few parts of the Southern Tier possibly even hitting the upper 30s.

Winds will remain breezy overnight, but most gusts should remain below 30 mph.

Clouds and lake effect rain showers are likely Monday, especially over the favored lake effect areas over the eastern Finger Lakes.

Highs Monday may not escape the upper 40s.
