EastCoast NPZ Posted August 17, 2016 Author Share Posted August 17, 2016 Again, not talking about the line of storms out west; I can see radar and extrapolate. I'm talking about local pop-up storms, just like those popping up in central and southern VA. Link to comment Share on other sites More sharing options...
dailylurker Posted August 17, 2016 Share Posted August 17, 2016 I know someone had mentioned this a couple days ago. The color of the sky has been so much better over the past few years. I can't believe how blue it has been during hot, humid days. When I was a kid the sky was brown. You couldn't even see the towers going up. 89. Hopefully we all score tonight. Devastating flash flooding for all! Link to comment Share on other sites More sharing options...

Yeah, WxUSAF mentioned it about a week ago and although I got the feeling that something was "different" about these recent hot days, until he said something, I couldn't place it. I remember in the late 80's and early 90's when I was racing bicycles, I would come back from a long, hard ride on days like the ones we've had this past week and my chest would ache for hours. I'm wondering now if it was because of the poor air quality. I was out this past Sunday for over 3 hours riding, and although I'm fatter and slower, I still worked hard (getting fat over a hill is tough), and no achy chest. Also hoping for an area-wide drenching tonight. But I'd be okay without damaging flash flooding. Link to comment Share on other sites More sharing options...

The blue sky would be muted to a light blue. Perhaps the Hot, hazy, humid days are over and now we just have hot and humid days. Link to comment Share on other sites More sharing options...

WEATHER53 Posted August 17, 2016 Share Posted August 17, 2016 When KA and I first started our work part of it was sky pollution observation. The 70's into early 80's were characterized by a near constant brown haze in the sky on hot and humid days ,you rarely see that anymore, anti pollution efforts were successful Link to comment Share on other sites More sharing options...

jacindc Posted August 17, 2016 Share Posted August 17, 2016 Now that you mention it, I do recall rather hazy days a long time ago. The blue sky would be muted to a light blue. Perhaps the Hot, hazy, humid days are over and now we just have hot and humid days. Ditto, I've been mentioning this to friends all week. The sky would be almost white on the hot and humid days, it was just a signature of D.C. summer days. I can't get over how blue the sky has been with temps over 95. Totally weird.

Kmlwx Posted August 17, 2016 Share Posted August 17, 2016 We certainly do have many fewer code red AQI days than we used to when I was a kid. Orange is still pretty common but I can't recall seeing a ton of reds in the past few years. Link to comment Share on other sites More sharing options...
Stradivarious Posted August 17, 2016 Share Posted August 17, 2016 When I was a kid in the 60's we didn't have sunsets in the summer, we had sun fades...now the summer sky reminds me of Florida... Link to comment Share on other sites More sharing options...

EastCoast NPZ Posted August 17, 2016 Author Share Posted August 17, 2016 10 minutes of wind-blown moderate rain and done. Now just stratiform drizzle. Based on cloud darkness, looks like the best stuff went north and south of me. A few flashies of lightning as it came in and nothing else. Now that it has passed east I can see and hear it strengthening. Getting much more thunder now. Cooled down at least, but very underwhelming.

It's hard to sustain that kind of action over a long distance. I'd tend to agree. 1) They are already reduced a bit from their peak winds. 2) There is activity forming ahead of it that may muddy the playing field. 3) The winds don't even look like 70mph right now. I'd warn it for 60mph if I were them. Subject to more velocity scans, though. Link to comment Share on other sites More sharing options...

It looks like the reports tapered off tho after the Luray and Stanley area patch of reports. I don't see any newer ones on my screen yet but it could be delayed. No doubt there could still be wind damage but I'm thinking 70mph is a bit on the high end at least at this exact moment. But there is not an appreciable difference from 60 to 65 or so vs 70. derechoooooooooooo Link to comment Share on other sites More sharing options...
Bob Chill Posted August 18, 2016 Share Posted August 18, 2016 Looks like the cell out in front appoaching Dulles is going to become one with the larger trailing complex. Hard to say how it all progresses east. Prob just some gusty winds and active TL followed by a lot of rain. Kinda doubt severe parameters will be met around the beltway.

I'd definitely lean towards the radar already shifting towards the heavy rain event vs the damaging wind. There's still a decent patch of winds on velocity but it's continuing to come down a bit more - slowly but surely. Maybe it can pulse up again.
