Interference from a new high rise in Tyson's Corner.

Enjoy. I'm in Williamsburg through tomorrow.

I love mesonets.

Terrible summer.

LWX storm survey from the damage in Baltimore earlier this week:

3 NW Thurmont

No. Snow is life.

I'll be out of the area early next week. Count on it.

Too early to get interested in Fri/Sat. Without nuclear grade heat and an EML, it's going to be tough to get any MCS across the mountains. Debris clouds could spoil us Saturday...shocker.

Starting to wonder if we even have sustained heat this year. Seems like rainy and cool is the way we're headed. The worst.

Yea they're dropping a lot in my neighborhood. There's still a song in the trees, but it's muted.

Baltimore County fire responding to a stranded boat near Craighill Light.

Absolute shaft job in Reisterstown. A few drops of rain and one bolt of lightning in the southern sky.

About what size?

You can see a few green pixel on the base velocity over Baltimore City.

Looks to be. Frederick Cell is starting to interact with a subtle boundary along Rt. 26. Might shoot up in the next couple of frames.

Dewpoint at my personal wx station back up to 63. Wind has shifted to SSW.

Gonna get our watch shortly:

Watch out along I-81

Possible TVS on the cell south of Pittsburgh. Some of the CAMS have that cluster spawning our nocturnal activity. That's the sector to watch, IMO.

Key takeaway: Craven SigSvr Parameter The simple product of 100mb MLCAPE and 0-6km magnitude of the vector difference (m/s; often referred to as "deep layer shear") accounts for the compensation between instability and shear magnitude. Using a database of about 60,000 soundings, the majority of significant severe events (2+ inch hail, 65+ knot winds, F2+ tornadoes) occur when the product exceeds 20,000 m3/s3. The index is formulated as follows: C = (MLCAPE J kg-1) * (SHR6 m s-1) For example, a 0-6-km shear of 20 m s-1 (40 knots) and CAPE of 3000 J kg-1 results in a Craven SigSvr index of 60,000. Units are scaled to the nearest 1000 on the web plot. Reference: Craven, J. P., and H. E. Brooks, 2004: Baseline climatology of sounding derived parameters associated with deeep moist convection.

SPC mesonalayis showing a 60 kt jet streak over Pittsburgh and we're seeing MLCAPRE starting to creep towards 1,500 j/kg. Intriguing.
