MONDAY MORNING UPDATE:

Dewpoint temperatures will remain high, in the upper-60s to low-70s making it feel truly tropical. That said, all the moisture in the air has prompted the National Weather Service to also warn of possible scattered thunderstorms later this afternoon.

The Central Finger Lakes, and Central New York will be the places where the best opportunity for this kind of weather will persist. However, these conditions won’t setup until late-afternoon.

The biggest threat with these storms will be isolated reports of damaging wind, lighting and gusty winds. Locally heavy rainfall will also be possible.

While the heatwave has made getting outdoors difficult for some – local forecasters say it helped with one area of concern: lake temperatures.

Last Thursday Lake Ontario was reported as 42 degrees near Rochester. Now, that temperature has risen nearly 20 degrees – with 61 degree temperature readings in the same locations.

Even in the Finger Lakes – water temperatures have improved greatly as of Monday morning. Keuka Lake gained 5 degrees over the weekend, reaching 77 degrees; while Seneca Lake cracked the 70 degree mark for the first time all season. Owasco Lake sits at 71 degrees and the southern tip of Cayuga Lake has reached 65 degrees.

Temperatures throughout the week are expected to hover between the upper-80s and low-to-mid 90s. Check out the FingerLakes1.com Weather Center for the latest forecast information.
