Best chances for storms/a lot of rain seem like it would from BWI south, right? At least that's my read on things. 

I got this right for up this way. 30 minutes of light rain. Now full sun. Looks like we are done.

My slight/enhanced risk days usually end in garden variety storms; My garden variety days usually end in damaging wind and hail.

Both usually mean I'm watering my garden. Today is no different lol

[CAPE]

Unless there is some enhancement, that line is weak sauce heading this way. Maybe enough to drizzle a bit on the drooping plants. My grass is already gone for the most part, as usual. Reseeding will commence in another week or so.

[Stormfly]

.12" isn't much but the rain birds (sprinklers) may get a break this evening as the garden looks OK.

Besides the isolated strong storm Tuesday to Thursday... sounds like Friday could be quite active per the afternoon LWX AFD:

.LONG TERM /THURSDAY THROUGH MONDAY/...
A strong upper level trough axis is forecast to pass over the Great
Lakes region on Thursday and shift eastward into the NE US by this
weekend. A surface low associated with the upper trough is forecast
to remain well to the north over eastern Canada but it`s associated
front is forecast to drop into our region sometime late Thursday
into Friday. Ahead of the frontal passage, warm and humid conditions
will lead to an increasingly unstable environment. Weak shortwave
energy ahead of the frontal passage combined with the unstable
environment will lead to a chance for showers and strong
thunderstorms on Thursday. The better chance for more widespread
strong thunderstorms will likely be on Friday when forcing from the
frontal passage will combine with decent mid level shear and SFC
CAPE above 1500 j/kg. If favorable shear and CAPE matches up well
with the frontal passage, our region could see a busy day for severe
weather.

This is a picture of severe weather luck in Balt. City this summer...mercy.

[WEATHER53]

Been without power since 4pm

About 5 very sharp bolts with thunder within one second.  Looks like a pole  by WTOP towers took a direct hit 

 

[WEATHER53]

Power back at 8:30 so 4.5 hour outage

most lightning this season and 4/5 strikes very close by

South of you in silver spring (near downtown), and I saw multiple cloud to ground bolts to the north. All were quite bright and loud. We did not lose power

How much wind is needed to turn helicopters over?

A lot.

[Stormfly]

Depends on the type of bird.
The 80+ gusts at Harford Airport would have easily turned over the single engine planes if they weren't tied down.

In any case, definitely legit severe.  Airports are devoid of wind shadows and what seems like a gusty barely severe storm feels like a CAT2 on the strip!

storms tomorrow ahead of the cold front?

Yes for Pennsylvania and points south of a Leesburg-Rockville-Annapolis line

Boo. It’s been a rough last week of softball, I’m banged up and bruised. Need a night off tomorrow before our end of season tournament Saturday.

I was just out walking and got drenched. Only lasted 5 minutes and sun was shining the whole time, but it came down hard briefly.

[WEATHER53]

Quite  a yellow sky downpour for 8 minutes. 0.35”

[WxUSAF]

Lots of distant thunder now behind the line. 0.08” deluge for MBY.

[IUsedToHateCold]

Deluge down here in the swamp.

[high risk]

Slight risk today includes DC at the northern edge.    Consistent with that, HRRR definitely likes the area south of town.

    Got 0.26" just south of you.   I posted in the Obs thread that the thunder really started cranking after the line passed, and you could see it in the lightning data.    There were many strikes well behind the rainfall, including one here that was maybe 75 yards away and took out our power for 5 hours
