High heat, humidity lead to thunderstorms Thursday

Thursday will be an excessively hot and humid day across the Finger Lakes, especially considering it is September. While record highs are generally unlikely to fall today, it will be hot enough that some caution should be used if engaging in strenuous activities outdoors this afternoon.
