Nice hail in DC, awesome storm.  Tons of cloud to ground lightning too. 

I'm on the tippy top of that storm trying to will it north. Definitely can hear the thunder with a few close strikes. It just now started to rain. So, I guess it is slowly expanding north.

Nice discussion by Mount Holly on the heavy rain potential for today into tonight-

A rather interesting meteorological setup exists today for the Mid-Atlantic region. A large-scale midlevel ridge initially centered in the western Atlantic will retrogress slowly to the Carolina coast by 12z Saturday as it aligns with transient ridging in southeast Canada. Meanwhile, a convectively-augmented vort max will migrate slowly clockwise on the northern periphery of the ridge, generally from the eastern Ohio Valley and central Appalachians this morning to the northern Mid- Atlantic coast by Saturday morning. Large-scale lift in advance of the meandering vort max will likely prove sufficient to generate scattered to numerous storms during the afternoon in our CWA via diurnal destabilization. Although there is subtle synoptic forcing as addressed above, subsynoptic lifting mechanisms will be rather weak and/or chaotic. These include orographic lift, sea/bay breezes, differential heating, etc. As a result, convection-allowing models are unsurprisingly variable in today`s convective evolution. There are, however, some similar characteristics among the guidance: (1) greater coverage versus previous days, (2) some semblance of convective propagation southward and westward, in association with ambient instability and (weak) low-level trajectories, (3) slow storm motions via weak tropospheric winds, and (4) multiple rounds of convection, with the evening/overnight rounds tied more closely to the larger- scale vort max. The greatest variability with the convective simulations is with the coverage/location of the overnight storms, with some models effectively stabilizing a large portion of the northern Mid-Atlantic from the daytime storms. Others are more aggressive in maintaining convection or developing new storms in close proximity to the vort max. Current thinking is that both scenarios will likely play out to some degree. Given the convectively-enhanced nature of the vort max (potentially exhibiting warm-core characteristics via MCV-related processes and attendant thermodynamic profiles), it would not be surprising to see more widespread convection during the afternoon/evening become more closely aligned with the track of the mid-/low-level circulation during the overnight hours.

A potentially very wet period upcoming, especially if the remnants of Ida pass over the region. With our extended summer season just beginning, get used to dealing with the mosquitoes well into October. Hopefully the Fall season will begin early this year, maybe by early November.

All the leaf litter and woody material on the ground around my house has started to smell bad.  I think it's all turning into a big rotten slime mess from all the humidity and rain this summer.  It's kind of smelly just to walk outside, usually I like the smell of natural decay but this is foul.  Got a quarter inch yesterday in another storm and I'm sure today won't disappoint either.

Looks like 5 more days of truly disgusting weather, then we get a break.  After that we are into September and while it’ll get gross again, it’ll probably be in shorter spurts.

I predict 0.00 for me and am certain that I will be watering my garden this evening

The best convection was progged west of the Blue Ridge the last 2 days, and it ended up where it usually does - in the metro areas- as I was left to run around to try to catch each of the 27 rain drops that fell on my property in order to fill a thimble.  

You and I will be covering our faces with cloth trying not to choke on the dust while swift water rescues and power outages occur again in the usual spots.

i missed the dc storm, but was driving down 270 at the time and could see the lightning.  looked similar to the one i experienced in germantown the other day.  just basically rained itself out, but had a good deal of lightning.  these cells have been legit the last couple weeks and the taller cumulonimbus clouds have provided some picturesque views lately.
