George BM Posted September 3, 2023 Author Share Posted September 3, 2023 1 hour ago, George BM said: I'm officially on 100 watch for IAD this week. At least tying the all-time September record of 99F there is starting to look more likely. But I didn't think it would be today though! Currently 99F.

pazzo83 Posted September 3, 2023 Share Posted September 3, 2023 so far the lower dews + higher air temps scenario seems to be playing out - we'll see if that continues. Link to comment Share on other sites More sharing options...

Normally, when it's in the mid-upper 90s in the mid-Atlantic, it's also humid, but the nw flow (along with the breeze) has been the base state all summer, it seems...maybe even since last year.

But we're also closer to the incoming midwest heat dome. This has been the entire summer out here. We're hotter than the UHI almost every day. Our summer has been nothing like DCA's. 97F high, at least I assume that'll be the high for today. 2 Link to comment Share on other sites More sharing options...

I don’t think I’ve seen an entire summer where IAD constantly beat DCA for daily maxes 97 for the high imby 3 Link to comment Share on other sites More sharing options...

Nah, it can locally increase the dewpoints in mid summer though. I think it has a relativity minor impact overall- if we have an airmass with dry NW flow from Canada, its not like the evapotranspiration(corn sweat)is going drive the dewpoints higher in any meaningful way. Probably a more notable (slight) local impact when the flow is more tropical in nature from the SE in a Bermuda high setup, for example. Link to comment Share on other sites More sharing options...

The mean h5 ridge has been to the west. Your area downslopes well, which means compressional heating. Competes with the UHI just to the east. Over here its been significantly less hot due to being further east, and ofc zero UHI. It has gotten quite dry here over the last couple weeks, but nothing like your area is experiencing over the last 3+ months. 1 Link to comment Share on other sites More sharing options...

Round Hill WX Posted September 4, 2023 Share Posted September 4, 2023 96 today in Round Hill. 97 is my yearly high…I expect we’ll beat that the next couple of days. We were outside today and it was warm but not brutal…dry and a nice breeze made for a tolerable experience at the brewery. Link to comment Share on other sites More sharing options...
