Warned.

Just got Tornado warned.

That cell to the east of it is looking good as well.

I'm assuming 50/20 tor probs?

Exactly 1" here since last night. (Herndon, VA) Up to 2.15" for August.

I'd say so.

Now IAD was at 101F for one minute just now.

IAD was at 100F for one minute a short time ago.

IAD has hit 99F thus far.

Assuming the smoke aloft over the Ohio Valley west of the Appalachian mountains doesn't block out too much sunlight a fairly decent sunset could be coming up.

About 0.13" here (Herndon, VA). Roughly 2.20-2.25" for July so far.

Could be a nice looking storm-cloud base over Springfield atm.

A thin line of clouds have been over northern VA and generally over my house since before sunrise. https://weather.cod.edu/satrad/?parms=subregional-Virginias-02-96-1-25-1&checked=map&colorbar=undefined

18z IAD sounding. Steep LLLRs and fairly high Pwats... though weak MLLRs. Could be some decent downburst/outflow winds should storms mature locally.

It's an MCV from a storm complex that died over Kentucky pre-dawn this morning. And, yeah, it'll be interesting the see whether it can fire up a batch of storms locally later. Storms are already forming under the vortmax.

Yeap. Everything Kmlwx said. That's my go to link for weather obs at IAD.

IAD has hit 101F. First time since 2012.

3pm obs: DCA: 103F BWI: 103F IAD: 100F

Looks like DCA has hit 104F! Wow.

IAD finally joins the triple-digit party at 100F.

BWI with a one-O-two.

1pm obs: DCA: 101F BWI: 100F IAD: 97F

Already 100F at BWI.

12pm obs: BWI: 99F DCA: 96F IAD: 96F
