A strong cold front will be bumping into our hot air mass. There is some increased humidity and instability thanks to the nearby pass of Tropical Storm Claudette. The net result will be a wide outbreak of severe thunderstorms this afternoon and evening, include the chance for supercell development.
Large hail and a few tornadoes are a possibility today.
This post shows the latest info, radar simulation, and live radar with lightning widget below.
Severe Storm Outlook
The Enhanced Risk includes southern Pennsylvania, with central Maryland in the Slight Risk.
There will be thunderstorms with the potential not a promise they turn severe.

Levels over 2,500 mark severe storm likelihood. These levels suggest supercells many develop along the front ridge of the mountains between 4 and 6 PM.
Watch means it might happen

Afternoon Surface Map
The cold front will not reach us until tomorrow. Ripples ahed of it will be responsible for multiple waves of energy. This will translate to a few lines of thunderstorms.
Severe Storm Outlook
The maximum energy will be to our north, but we are own the edge of the Enhanced Risk Storm Risk region from NOAA.
Live Radar and Lightning
See the radar simulation below.
Radar Simulaiton —->slider
This product has NOT been doing a good job lately. It has underplayed the activity of severe storms AND the timing has been as much a 1 to 2 hours late.
I show you this for a guide. Please compare to the live radar above.
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.
This was designed by Shannon Berk and we will be wearing it through spring and to the beach.
Double Benefit: Proceeds will be split between our nonprofit Just In Power Kids and the development of my new weather website. That has been scheduled to be ready to launch in May.
