A Sever Thunderstorm Watch has been issued for most of our region through this evening. We have already had warnings issued in PA, western Maryland, and VA. The primary risk factors are for damaging winds over 60 mph, large hail over 1 inch, flash flooding, dangerous lightning, and an isolated tornado. But behind the storms will be cooler air (briefly).
A Watch means it might happen
A Warning means it is happening NOW
The cloud development since late morning has been impressive. Some tops have reached over 50,000Ft, compared to normal storms ruching about 35,000 Ft.
Check out the cooler 70s behind the storms in western Maryland and even in York PA.
11:45 AM to 2:45 PM
- Damaging Winds over 60 mph
- Flash Flooding
- Dangerous Lightning
- Isolated Tornados
The short range models are NOT ding a good job. I will show a simulation slider below for a gernsl gauge, but it has already missed the strong cells in PA. York County just had a storm with 50,000 Ft tops and was trying to rotate. The HRRR Model never showed it! So there will be more it missed. Basically, storms will overachieve today.
Radar Simulation —> slider
This HRRR Model missed the storms in PA, so we need to expect it may once again be underplaying the coverage. The timing may also be a little slower than reality. But this does suggest the main action in metro areas will be between 4 PM and 6 PM
