Definitely looks like a cold pool developing behind this line. Woo storms for everyone today?

Hopefully so. Spread the wealth for everyone. Feels like that kinda day storm wise

[mappy]

I’m hoping this mornings storms didn’t ruin this up here 

[87storms]

Glad I biked during lunch. The late afternoon timeframe looks spicy.

STW just issued for 80 mph gusts and golf-ball sized hail. Warning box is 1/2 mile to my north.

You've recovered nicely. The area is still 5-7 degrees cooler than south of I-70 but it's recovered a lot faster than I expected.

be tough to bust at this point (famous last words)

A bust would almost be as bad as smoking cirrus when a low passes to far to the east in winter.

It got sunny as soon as those stormed moved thru, which was nice

[mappy]

Thunder… probably from the cell near Bel Air

Blacksburg playing the Sterling game, issuing large STW's for multiple counties for the incoming line.

Surrounded by warnings

LWX smashing the warn everything button

Everyone west of 95 do you smell pine in the air. That was a telltale sign when the deracho was approaching. The smell was in the air well before the storms hit my location. Anyone experiencing that yet?

Same here. And now the Bel Air cell descending my way.

This is not even close to what that was.

[Lucketts]

Thunderstorm has developed before the line and we’ve got it all.

Thunder, lightning, heavy rain, wind, flickering power.

[WhiteoutMD]

This is not even close to what that was.

Is this a MSC Approaching ?


.

[vortex95]

Radar looks "meaty."  Not only the SQLN but discrete cells forming just ahead.  It does not look like it is gusting out yet which is good.

I like the CU streaks on the VIS over the DC area.

I think you mean MCS. But yes that is what is approaching. Not a derecho

Got some of those puffy cumulus boys overhead in Silver Spring... they're growing 

[Kmlwx]

Some useful terms for everyone to remember:

MCC = Mesoscale Convective Complex (a specific type of MCS)

MCS = Mesoscale Convective System (of which a derecho is one type of MCS). 

Derecho = a very intense MCS with damaging wind (long track and wide swath) 

[SolidIcewx]

As someone who is a transplant from SEMI. THIS is the shit i like to see in my storms! Nice big MCS.

[batmanbrad]

new MCD from SPC indicating they think this line could strengthen as it moves east into increasing instability:

The only difference from an MCS and MCS is the extent, duration, and eccentricity of the very cold cloud top canopy.  As for sensible wx, the both can produce high-end svr wx and unreal LTG displays!

[SnowenOutThere]

You all look like you're in for a good MCS today. I'm out in Madison WI for the week so I'll miss it but hoping everyone can cash in on some widespread rain.

Over the last 30 minutes of radar frames the line has coalesced nicely. looks ready to slam everywhere in this forum, pretty much (east of 81)

Maybe this time we can get it to really go nuts before it gets to the bay high dew point area just E of i-95?  I can't tell you how many times Silver Spring misses out b/c of this!

[SolidIcewx]

Is this system starting to get some bowing ?

Missing to the north but plenty of lightning in the area. Ears popping.

[MN Transplant]

Interestingly, 5 years to the day of the strongest storm in decades (including the Derecho) in my neighborhood.  August can deliver.
