The End of the Heat

Much of the Finger Lakes region will have hot and humid conditions again Thursday, at least until thunderstorms become widespread this afternoon.

A few showers already exist this morning across Tompkins and Cortland Counties. Elsewhere, skies are sunny and the temperature is already pushing into the 80s as of 10 am.

By the early afternoon, heat index values will once again be in the upper 90s and low 100s across the northern half of the Finger Lakes.

Showers and thunderstorms will become more numerous during the afternoon hours. Multiple clusters of storms will be possible.

Thunderstorms will be least likely near Lake Ontario, but most of the region should at least have storms in the vicinity at some point during the afternoon.

Frequent lightning and heavy rain will be the primary threats from the storms. A couple could have some briefly strong wind gusts as well. Widespread severe weather is not expected.

Storms will taper off this evening as the daytime heating is lost. However, showers and a couple more thunderstorms will develop overnight as a cold front approaches. Most of the rain should be out of the Finger Lakes before 9 am Friday morning.

Excellent Weekend Weather

Behind this front, a refreshing changing will move into the Finger Lakes.

After a cloudy start to Friday, skies will turn sunny later in the day. High temperatures will peak in the mid 70s.

A northwest wind will blow behind the front with gusts over 30 mph likely during the afternoon hours. The wind will let up during the evening hours.

With lighter winds and clear skies, temperatures will fall into the low and mid 50s by Saturday morning. Saturday will turn out similar to Friday, with plenty of sun and temperatures in the upper 70s. The wind will not be as strong on Saturday.

Sunday will be a bit warmer as temperatures return to the low and mid 80s. The humidity will be very low though, so it will feel quite comfortable. Winds will be nearly calm.

Monday will also be sunny and warmer yet. A few places could even return to 90 degrees, but the humidity will still be much lower than it has been this week.
