Heatwave to Envelope the Region This Weekend into Early Next Week

Friday through Sunday

Hot and humid with highs in the lower 90s and dew points in the upper 60s and lower 70s. This will allow for heat indexes to climb into the mid and upper 90s.

A few isolated showers and thunderstorms can’t be ruled out Friday through Sunday due to the instability in the atmosphere from the heat and humidity, but we do not expect widespread storms like we saw the past couple of days.

“During the afternoon, short-range guidance depicts a few hit and miss thunderstorms, but nothing terribly organized.

Any storms that do get going have the potential of becoming strong/severe with damaging winds and hail being the main concerns.” read more
