WPC expanded the moderate risk for excessive slightly southward to include DC to Annapolis for later tomorrow into Tuesday.. Pretty good setup for training storms.

Waiting for @EastCoast NPZ to complain even though there is a heavy storm right over top of him on radarscope 

I'm right on the edge of rain.  Got 5 minutes of wind blown rain.  Ground wet, but not much.  Ripping less than 1/4 mile away.  Impressive to watch it form, but just barely too far west for this one.

Annapolis (not a climo site but should be, IMO) hit 101.

I can see the storm SW of York, PA from my apartment in Columbia. Looks decent from here - have a hyperlapse running on it right now. 

Yea I can see them from Reisterstown...looks like they're getting some aid from the hills maybe? Couple of decent towers.

Another storm blew up in the wake of the first.  This one a flush hit, but still on the edge.  Branches down, patio furniture blown off, and at least another .5".  Sun shining for most of it.  Lol.  Grateful for the rain and cooling my roof.  Temp knocked down to 78F.

Outflow boundary came through Souther Stafford and knocked temp down by ten degrees. Was around 100, now sitting at 89.6 with a small thunderstorm with a lot of thunder and lightning nearby.

 

ETA: much more comfortable outside

Structure from a distance looks really nice - even an anvil maybe starting. Will upload the timelapse to Youtube later on once it finishes.

Just had about 10-15 minutes of marble sized hail and towards the end we were seeing hail about 2/3'rds the size of golf balls. Somewhat unsual storm in that it developed to the east of the area and expanded westward into my area.

Car thermometer hit 104 on the SE/SW Freeway, dropped to 102 as I hit Virginia, then got down to 84 as I went out the GW Parkway and hot the spots where it had just rained.

Quarter size then ? Real nice unless your car is parked outside lol

Stationary on radar just to your east the past 30 to 45 minutes.  Probably ffw soon I'd think

2 boundaries getting ready to combine over my general area. One moving south from the PA cell and one moving north from the convection to my south. Would love a garden soaker this evening.

Getting somewhat impressive rain at this time with fairly strong winds as well. Quite a few twigs and small branches down. Very localized storm basically just in the Hanover area and surrounding suburbs to the east.

Actually think its been there for maybe an hour and a half or so. Was outside earlier complaining about seeing and hearing the storm to my E/NE thinking I wouldn't see anything.

I drove back from the beach today, and my car thermometer which is pretty accurate (have checked it against reliable stations and it’s usually within a degree) was between 98-102 from just before the bay bridge all the way to takoma park on the beltway.  Was 100-101 around Annapolis.

Thankfully the larger hail was very sporadic, mixed in with the marble sized hail at the end. And speaking of cars, I better go check my truck and jeep.
