JAMESTOWN – The muggies will stay with us through tomorrow with a chance for some stronger thunderstorms in the afternoon before a Cold front passage ushers in much cooler and refreshing air by the weekend.

We will stay quiet through tonight with more clouds filtering in overnight. It will be very warm and humid, making for rather uncomfortable sleeping conditions if you don’t have air conditioning. However, the breeze will start to pick up out of the south at 10 to 20 MPH. Lows 70 in the valleys, 75 at the lakeshore.

As a Cold front lurks back to our west, the humidity will surge into oppressive, near tropical levels on Wednesday. Along with that, scattered showers and thunderstorms will spark ahead of the front with the high humidity and early sunshine producing fuel for the storms to develop.

The NOAA Storm Prediction Center maintains a standard Slight risk, a level 2 out of 5, for severe thunderstorms late tomorrow afternoon and evening across all of Western New York and Northwestern Pennsylvania.

The primary threats with storms will be damaging wind gusts, large hail, and locally heavy rainfall. Highs 83 to 92.

After the Cold front sweeps through, much cooler air will be ushered in with a more westerly to northwest flow aloft for Thursday and Friday. There will be small chance for a leftover shower through the day otherwise partial sunshine each day. Highs in the mid 70’s.

We’ll cool it down even more for Saturday with highs in the mid 60’s.

The weather will stay mainly dry through the second half of the weekend into early next week with sunshine returning and highs slowing climbing back into the lower 70’s by next Monday.
