Impressive LSR out of Grafton, WV for that western line "Sustained 35 mph for 5 minutes with gusts to 62 mph."

[MN Transplant]

Bit of initiation happening west of DC from the outflow from the earlier southern storms.

Yep, trying to pop off a bit. Wouldn’t mind a little storm tonight to end the weekend.

Poppin off. Sunset magic hour. Boundary layer decouples and you get a stray gust front (La Plata storm) or subtle s/w aloft and go time.

[Kmlwx]

Garden variety heavy rain in Odenton. 

[Eskimo Joe]

Constant lightning just to my west in Reisterstown. Cats army crawled down to the basement.

[Eskimo Joe]

Interesting radar signature just NW of Sykesville, MD 

[NorthArlington101]

Little bit of lightning in the distance at least. Oh well

BWER on the E Frederick / W Carroll Cell

NoVA got skunked. Line to the west is fading. Just showers later I would think.

[Stormchaserchuck1]

Probably my best thunderstorm of the year ongoing

[Eskimo Joe]

That cell in Libertytown/Walkersville appears to have been legit. Some reports of structure damage. . .maybe a tornado?

[snowfan]

Thats quite the cluster from baltimore up into Lancaster co. Impressive amount of lightning.

This is an issue with MADIS. The 83 mph gust is from a sonic anemometer on top of the Bay Bridge. That is the first report. The second 83 mph report in Parole is false, it’s due to a bug that duplicates the Bay Bridge sensor at SHA headquarters in Parole. The lay/lon is wrong in MADIS. The 75 mph gust is from a buoy at the mouth of the Severn.

Are their systematic issues w/ sonic anemometers?   W/ all the new mesonet sites in MD the last few years, are we seeing wind measurement issues often?
