Saturday July 17 2021
Today is the last day of the current heat wave, and it is going to go out with a bang. Yesterday, Baltimore hit 98ºF and we may match it today. But the Heat Index will be 105ºF+.
Storms will erupt mid afternoon through evening. There is a risk they turn severe. With ample moisture AND some slow movers, rainfall could push 2”/hour rates. As a result a Flash Flood Watch is in place as well.
See the radar simulation below for most likely timing in your location as this develops in the mountains at lunchtime, and reaches the beaches by midnight.

Sunshine State Of Mind
I am done with the cold and snow (for the season). I am embracing my wife’s mantra of Sunshine State of Mind.
