Severe weather expected this afternoon and evening

SEVERE THUNDERSTORM WATCH is in effect until 8pm for counties in pink. Storms are developing and moving in from the west. There is the potential for storms to produce straight line damaging winds. Also, torrential downpours, which may lead to flash flooding is also a huge concern. There is a small tornado chance in our far southeastern counties. Hail may also be possible in some of the isolated stronger storms.

Warning

FLASH FLOOD WATCH in effect until 10pm for counties in green. Heavy rainfall is very likely with storms that develop this afternoon and evening. With the ground already soaked after recent storms, the potential for sudden flash flooding is very high. Be alert and prepared to move to higher ground if need be. Storms are producing torrential downpours already in Mifflin and Juniata and will continue to move east.

Warning1

THIS EVENING: Weak boundaries across the area will interact with the heat and humidity from today along with some strong mid-level winds resulting in the possibility of strong to severe storms this afternoon and evening. Wind damage is a big concern along with heavy downpours. Storms should wind down close to 8pm with just a few lingering showers possible.

Evening Forecast

OVERNIGHT: Muggy, warm with patchy fog and an isolated shower can’t be ruled out. Lows will be in the upper 60s to low 70s.

TOMORROW: Strong cold front arrives and will produce the chance for showers and storms. No severe weather is expected except for flooding will be a concern with the already saturated ground. Highs will warm to the low 80s.

OUTLOOK:  Much cooler air will push in by Wednesday as a deepening trough spills below average cool air south into the Ohio Valley. Highs Wednesday may not even get out of the 70s and the very unseasonable like temperatures will continue through Friday. This is supposed to be the hottest time of the year but we will get a nice refreshing stretch of cool air. Isolated storms will return for the weekend.
