It was promising this morning with the lack of clouds, but now there's tons here! Really hoping we can move these out... satellite shows a clear area before the front.

you're fine. The instability is already solid and in place. Just gotta see if any pre frontal stuff hurt the main line.

More concerned if low level lapse rates will be a little less favorable for wind mixing to surface.

So if you had a child at an outdoor nature camp in Downingtown today on a road that was very prone to Valley Creek flooding, what time would  you pick him up?  Camp is over at 4pm, I'm wondering if I should grab him earlier than that.

[tombo82685]

[Qtown Snow]

[tombo82685]

this is that trailing s/w for later tonight for i95 and south and east that could further enhance rainfall

no hail till i get home into garage, thanks

Disadvantage to working in a windowless room is that I won't get to see any sort of light show.

The question of course is whether or not we'll lose power though. 

It's been three years since the last bad hail storm here in Berks County though, right? I believe it was in 2014 around this time.

Big hail core out in southwest Fulton co

70 mph wind gust hazard for what looks like the beginning of the line in SPA

[Treckasec]

 

I think we need to watch that little area of higher DCAPE values in front of the line. If we can tap in to some of that, better chance for damaging winds.

Can hear some thunder here at the office, but looks like the storm is going to skate by to our northwest. 

Ran out at lunch and moved my car away from the tree it was near just in case.

Bowing out?

[greg ralls]

Yep, looks like a pretty classic bow forming north of Hanover to my unprofessionally trained eyes.
