September Discobs 2025

[vastateofmind]

Welp, planned to mow the front lawn early-mid afternoon, started getting Rain Alarm alerts almost an hour ago. I scoffed at them...because I sometimes get false-positives from that particular app (e.g., fog, low lying clouds, etc.) plus, it's supposed to be gorgeous this afternoon, and has been all morning and (up until) the past hour:

Get about two passes in on the front lawn...and the sky opens up, heavy downpour, can't hardly see across the street. That started about 40 min ago. Call me a cynic, but I didn't see this reflected above, nor in the morning disco, at least not for close-in NoVA burbs:

These are the kind of whiffs in forecasting that really piss me off. Can I mow tomorrow, or early next week? Yeah, I can likely fit it in with all of the other life crap. But c'mon...can we get at least a bit more of a heads-up in the disco (which is usually what *I* pay attention to)?? Yeah, precip might not happen (and THAT'S usually in hard winter around here)...but this is annoying.

Ironically, we had a small picnic planned for our back patio/yard for midday today but had to cancel last-minute...thank God we did, or it would've been one helluva fire drill.

P.S. -- it's STILL raining almost an hour later.

It does say "a few showers making it as far east as Southern MD".  90% of the area is dry.  They probably should have put a 20% POP in, though..

To your point, LWX has suddenly and retroactively changed their tune (though not necessarily in the PM disco update):

I appreciate your observation...and honestly, your personal inputs here over the years. And please believe, I defend your profession more than you know....I only approach this from a hobbyist standpoint, but twice already this afternoon, I've had two neighbors ping me -- "yo, man...IT WASN'T SUPPOSED TO RAIN THIS AFTERNOON, WTF??"    I got nuthin.   

Who knows...maybe we may have a microclimate thing going on here? This is anecdotal, but I'd say we've had exactly this kind of "blow-up" very localized shower/storm over the Hayfield/Kingstowne/Franconia area several times over the past two years, where almost no other locales in the close-in-NoVA burbs had nothing. And it's like it blows up...and rains/storms like hell...and then dissipates very quickly. That happened this afternoon, and at least a few times over the past two years.

I (along with a couple neighbors) were astounded when the sky opened up about two hours ago. It didn't even LOOK that showery/stormy if you looked to the west/NW (unless you looked at radar) but boy-howdy...did we get a good gully-washer for about an hour.

Yeah, it’s tough when the result is this

If that rain in PG county was a few miles more east it would of cost me a lot of money today. I wasn't expecting training tropical showers. Thankfully it missed my work site in Crofton. The summer of rain won't stop in the lowlands.

Picked up about 2/10ths around an hour ago with a thunderstorm, now that is back-building towards me and I can hear thunder again, maybe a bit more? 

[IronTy]

Tons of thunder moving in from the west at DCL.  It hasn't reached us yet at the cabin but it's getting close.  Breezy and 67F.  Need the rain here so I hope it makes it.

Yep, way over 1/2" and still raining pretty good with T&L. Nice 2nd storm of the evening

Nice... can definitely see a nice light show back your way... In fact could see lightning high in the sky from just west of Charlottesville near Ivy driving home a hour ago...

Waiting to see if this essentially non moving storm about a half mile to my south can drift north.... 25 minutes now of T&L with the smell of rain in the air , but no rain yet..

Your work is valuable and I like it

Perhaps... after taking a closer look I see they do not emulate my version of IntelliStar. The most "advanced" version of IntelliStar.

I also have this...

But this is really good work...

Still kinda jealous.

Most surprisingly this has turned into a legit stormy overnight down here.... Over 2 hours now of continual thunder and vivid lightning... Occasional rain about 0.4 now..

[BlizzardNole]

Well that was awkward down in Calvert yesterday LOL.  We visited for a b-day dinner at a restaurant on the bay and I was saying all week "oh yeah we can sit outside - it's gonna be perfect weather."  I'm thinking what the heck is this as we drive south thru a heavy shower around Dunkirk, then it proceeds to rain much of the afternoon.  That was unexpected!

[wxdude64]

The 0.74" that fell from those rounds of thunderstorms yesterday evening until about midnight sets a new rainfall record for date, breaking 2015's 0.40 inches. Surprised how low that number is considering we are in prime tropics season, must have been swings and misses here. Anyway, starting day off in the fog and 57.4/56.8. That also took care of worrying about 'dry September's', lol.

This picture doesn't do it justice how dark this cloud really was. moisture laden storm cloud as i visited family.

[CAPE]

Overcast and 68. A tad gloomy but dry and a Fall like feel. Nice day for working outside.

I mean Florida has downpours that can stop traffic.

The Atlantic cloud factory has shown slight weaknesses the last few minutes in Baker Park. Otherwise, it’s been cranking in ways only the mid-Atlantic can.

.16" last night makes .77" total rain for Sept.
