Late Day Thunder Threat, Perhaps More Widespread
A disturbance in the atmosphere will move into the region, with thunderstorms likely to break out in the afternoon and evening hours from west to east across the Delaware Valley. We're likely going to see strong thunderstorms breaking out in the region thanks to the continued heat and humidity, with some of those storms perhaps becoming severe in spots.
In addition to the threat of severe storms, heavy rain is possible in the strongest of storms. Stop me if you've heard this one before.
One of the differences between yesterday, as well as the days prior, with today is that temperatures will be a notch or two cooler in Philly. They took that step back in Allentown yesterday (86). Philly probably flirts with 90, down a degree from the 91 degree high we had yesterday. With enough clouds around, it wouldn't shock us if we missed the 90 degree mark by day's end but we do foresee at least some hazy sunshine around.
Another difference will be higher humidity levels as dew point values likely hang around or just above 70 for much of the day. Yeah, it's going to be a bit tropical out.
