*EXCESSIVE HEAT WARNING IN EFFECT UNTIL 8 PM SATURDAY FOR CHEMUNG, SCHUYLER, STEUBEN, TOMPKINS, TIOGA (NY), & BRADFORD COUNTIES*

Scattered showers and thunderstorms Friday evening. Heavy rainfall along with gusty winds, hail, and frequent lightning occurring as those storms passed through the Twin Tiers. Multiple reports of trees down and downed power lines as the storms moved through. A broken line of showers and thunderstorms moving south of the Northern Tier by 8 pm, but lingering showers and thunderstorms still possible through the overnight. Staying warm and humid with lows Friday night near 70 degrees. Foggy conditions through late overnight.

Concern for the weekend continues to be hot and humid temperatures. With temperatures climbing into the mid to upper 90s Saturday afternoon and dew point temperatures in the low to mid 70s, this will put heat index values near 110 degrees. Heat index values this high can create a dangerous situation in which heat illnesses could become likely. Make sure to limit outdoor exposure, drink plenty of water, use air-conditioning, stay in shaded areas, and check up on relatives, neighbors, and pets. Chance for isolated showers and thunderstorms during the day, otherwise a mix of sun and clouds. Chance for showers and thunderstorms lingers Saturday night. Little relief from the humidity overnight and lows in the low to mid 70s.

Heat and humidity continues Sunday before a frontal boundary slowly moves through the region. Highs Sunday near 90 degrees and heat index values near 100 degrees. Chance for showers and thunderstorms for the day. Cold front provides some relief from the heat and humidity early next week with highs Monday near 80 degrees. Chance for showers and thunderstorms Monday, then drying out for Tuesday.
