Looks like a Cat 1 outside in Woodley Park right now.

That might be my favorite app. Pro Tier 1 is well worth the money if you don't already have it. Tier 2 has a ton of cool features but it's $100/year.. too much for my needs.

Haven't those been mandatory since the mid-70s? They certainly made a big difference, but I think the improvements we've seen in the past 20+ years have much more to do with the 1990 amendments to the Clean Air Act than anything else. Those regulations targeted the big commercial and industrial pollution emitters.

Looks good, summer can end now.

I'm only in my late 20s and even I've noticed a huge difference in summer air clarity the past 5-ish years compared to growing up in the late 90s/00s. Code red and orange days were pretty regular and would often last for days in a row. That combined with mild asthma really made me hate summer sports. I can't remember a stretch like those recently though.

Cool summer inbound BWI 97F DCA 98F IAD 95F RIC 98F

DCA reported Mod Snow at the onset of precip. There's a sudden temp/dew drop, pressure jump, and then a subsequent rebound around the same time. What am I seeing here, computer error? Glitch in the matrix?

Finally under 30 in parts of the DC. 29/15

Ripping downtown near the WH, not much in terms of accumulation though. The weather station near my place in NW is a full 4 degrees cooler than DCA right now. 35/33 at DCA, 31/31 at home.

Inbound stratus angle.. that's gotta be a new one for the weenie handbook

Temps in WV and central VA are significantly lower than forecast right now.. white line is freezing, blue is 30. Note that it's averaged out over a decent area so there's heat islands somewhat under-represented here.

38/18 here in NW DC for the past hour.

the 23z run has the surface low ~150 miles northwest of the rest of guidance riding the Apps at hour 18. That's why it's so warm. As others have said, it's outside of its useful range.

same here!! It was my senior year of high school. I'd always been a snow weenie, like keeping a snowfall journal at the age of 10 level of weenie, but that one sticks out and got me into the actual science. Great memories. I had to go knock snow off the lower limbs of a massive loblolly in my neighbors yard so they wouldn't snap off. My parents also had my brother and I shovel the driveway at the "halfway" point sometime in the middle of the night. Enjoyed every minute of that storm. I remember 02-03 well but was too young to really get into this stuff. We did build an igloo that year though

someone gave him a public shaming

I think most people on this board would agree we have had an exceptionally long and active severe season this year... well into August now. Just because your back yard got missed by a couple miles a handful of times, doesn't mean Sterling isn't doing their job well. A warning is just that.. a warning. They are telling you there is potential in your area for severe weather. It's up to the individual to look at radar, a weather app, or the sky. People need to take some personal responsibility for their safety. If someone deems it a false warning for their backyard then so be it. You can't blame that on NWS. You aren't required to take their advice. As a "youth" I can tell you I'm very appreciative when my phone has a message that pops up saying I just got boxed for severe. I don't think anyone is crying wolf. I think we're just witnessing the natural progression of forecasting which is higher detail on a smaller scale. There are inherently going to be more "misses" with that approach because of the increased volume... but it's more accurate overall.

So the suggestion here is for NWS to only warn storms after they've already happened? Makes sense to me

Ice pellets and mangled flakes trying to mix in here in NW DC. Closest weather station has the temp down to 34. It was 39 at noon. DCA is still @ 40 lol

Yellows inbound for DC!
