DLMKA Posted July 6, 2020 Share Posted July 6, 2020 What’s the primary driver(s) for the air quality alerts across much of CONUS? Link to comment Share on other sites More sharing options...

A few things combining to create these: frequent evening fireworks this weekend, low wind and dry dewpoints. It's another benefit of living near the lake; typically if you have a lake breeze that's enough air current to mitigate the poor air quality once the lake breeze kicks up.

It's another benefit of living near the lake; typically if you have a lake breeze that's enough air current to mitigate the poor air quality once the lake breeze kicks up. The lake breeze clears out dust and pollen but increases invisible ozone. If you're sensitive to ozone the lake makes it worse. It tends to have less pollen and dust though if that's what bothers you. It's kind of a choose your poison thing. It's not as clean as an ocean sea-breeze because the smaller volume of the inversion-trapped marine air can collect more and more pollution over time. Stagnant high pressure is causing high ozone levels near the lakes. There's some trapped fireworks smoke around as well. 3 Link to comment Share on other sites More sharing options...
hawkeye_wx Posted July 6, 2020 Share Posted July 6, 2020 88º, officially, in Cedar Rapids today. I'm sure it was 90º in town with all the buildings and pavement and very little breeze. Link to comment Share on other sites More sharing options...
cyclone77 Posted July 6, 2020 Share Posted July 6, 2020 93 at MLI and 94 here today. Wind was pretty calm so even with the lower dews in the 60s it was a bit uncomfortable. Front yard is baking. The corn across the street, and the field behind the back yard still look okay, but the leaves curl up pretty good during the heat of the day. 3 Link to comment Share on other sites More sharing options...

Warm start and perhaps a slightly stronger gradient to delay the lake breeze a little. Link to comment Share on other sites More sharing options...
purduewx80 Posted July 6, 2020 Share Posted July 6, 2020 Quite the coast-to-coast ridge on today's ensembles on/around d10-15. Seeing widespread 5940+ heights in the EPS means is impressive - GEFS below not as crazy. 1 1 Link to comment Share on other sites More sharing options...
Indystorm Posted July 7, 2020 Share Posted July 7, 2020 Yep, it looks like this heat dome is going to stick around for awhile this month with only minor fluctuations. I have moved from central IN up to Griffith to keep an eye on our moderator Hoosier. lol Actually I have moved up here to be closer to family in my retirement five minutes away in Highland. But I will miss sending in reports to all of you from the ne side of Indpls metro as I have been doing for the past six years. 2 Link to comment Share on other sites More sharing options...

Congratulations on your retirement, but do people in your profession really ever retire? I'm glad that you have the opportunity to be close to your family.

Indystorm Posted July 7, 2020 Share Posted July 7, 2020 Thanks for the well wishes Hoosier and IWXwx. Since I grew up in Hobart it's like it's around the world and back again. Now if we can just get past coronovirus with a vaccine or effective treatment I will be most happy and thankful. In the meantime I intend to get out hiking locally and watching the weather.

purduewx80 Posted July 7, 2020 Share Posted July 7, 2020 Looks to be a little bit higher threat for a few thunderstorms in the region this afternoon, with the lake breeze slowly moving inland and a weak disturbance now in NW IA/SW MN. Storm motions will be <10KT so the few who get rain may get a good/brief soaking. Link to comment Share on other sites More sharing options...

Hoosier Posted July 7, 2020 Share Posted July 7, 2020 ORD is running greater than +8 through the first week of the month. The record warmest July was like +7.4. Will be interesting to see where it ends up. I certainly think it will be among the warmest Julys. 1 Link to comment Share on other sites More sharing options...

wisconsinwx Posted July 7, 2020 Share Posted July 7, 2020 Boundary palooza as it has been the last few days. Always interesting when you have a shortwave and the lake breeze both in play. Those storms near Madison look pretty angry, but we know how this can play out, already had a weakening storm move through so at least on the board once again. 1 Link to comment Share on other sites More sharing options...
