22 June 2010 Chase - Southern PA and Northern MD

Jason Foster and I just got back from chasing... was about 4-5 mi south of the reported tornado in SE PA. We didn't see the rotation or tornado (we were on I-76), but we did see the nice wall cloud that spawned it. Note that the TOR producer was not actually the cell that got TOR warned later on :P Pics and screen grabs coming soon.

Things we experienced today:
- Beautiful wall cloud.
- Two double rainbows, one of which was literally right at the ground.
- Dime sized and maybe a couple nickel sized hail (as we "core punched" the second cell that formed to our south).
- Estimated 60-65 mph wind gusts (as we were standing outside filming the tornadic storm).
- A large tree down in Cecil County, MD blocking a road just south of Rt. 1 (which we reported).
- Vivid CG lightning from three different cells.

We drove through an area with a pretty bad road network, especially during "rush hour," so we weren't able to catch up to the TOR warned southern cell after an hour of pursuit. All in all, we did see a lot of interesting things, got on the only chaseable tornadic cell of the day (so far), so it turned out to be a pretty good chase day.

Severe Weather Continues...

After chasing 4 of the last 5 days (including this afternoon), not too much has been seen. I'll post pictures and recaps tomorrow after work. There will be no What to Watch Fore(cast) today since I have to get everything ready for chasing.

Chasing Opportunity Tomorrow and Over the Weekend

A slow-moving cold front will work its way into the Mid-Atlantic tomorrow, which will trigger severe weather Thursday for most of the Mid-Atlantic. Shear looks decent, LL lapse rates are superb, CAPE is good for the area, there's plenty of moisture, and some UL dynamics will be enough to trigger a good amount of severe weather, including an isolated tornado or two (or five?). I anticipate a good chasing day in Southern PA and Northern MD as storms cluster and form loose lines as they move eastward at 20-35 mph.



As the front stalls out of the region this weekend, a series of disturbances will be passing through in the upcoming week. These disturbances will give the Mid-Atlantic several more looks at severe weather, the first of which will be towards the end of the weekend.
