87storms Posted September 4, 2023 Share Posted September 4, 2023 This is a deceptive heatwave...in Vegas, they call this a reprieve. Very low humidity for this area...a continuation of the same general pattern. Just got a bike ride in which I thought had potential to be a miserable decision, but turned out to be more tolerable than I expected, especially with the breeze. 4 Link to comment Share on other sites More sharing options...

Mrs.J Posted September 5, 2023 Share Posted September 5, 2023 So not only have the trees started to drop leaves due to the drought conditions up here. Just this weekend I started to notice corn fields, that usually are not cut down till well into Oct/Nov, are being cut early due to no ears of corn on them. These are the feed corn fields. And what has not yet been cut the stalks are already drying out. There are a few hold outs still trying to keep their lawns somewhat green. But most including myself gave up months ago. My drought tolerant plants are still holding on but I think I have lost a brand new mini azalea bush. I am hoping it has just gone dormant. The tree line behind my house is really struggling to keep leaves on. Now this oppressive heat building back in for a few days which will keep us all inside again. I do not expect much fall foliage over here at all this year. 3 Link to comment Share on other sites More sharing options...

I have access to local weather records back to 1893. 1958 is the halfway point. It is amazing how many more +90 days occurred pre 1958 compared to post 1958. I have been checking daily for over a month. A high of 94 yesterday and low of 59 at 6:30. Link to comment Share on other sites More sharing options...

DCA is running well ahead of yesterday while IAD is a touch ahead. The clouds hung around yesterday so the comparisons are a bit tough to make. My station is actually a degree behind.

pazzo83 Posted September 5, 2023 Share Posted September 5, 2023 11am DCA: 90 IAD: 90 (although 91 at the first 5 min ob after) BWI: 91 2 Link to comment Share on other sites More sharing options...
MN Transplant Posted September 5, 2023 Share Posted September 5, 2023 The 5-minute ob reminder. There will never be a 98 degree 5-min ob (only the hourly obs at 52 or 53 past) because of the silly rounding that is done, but any 100 is legit. 2 Link to comment Share on other sites More sharing options...
pazzo83 Posted September 5, 2023 Share Posted September 5, 2023 lol still the dumbest thing that the temp is recorded in F and converted to C (presumably to align with the international standard for a METAR?) and then rounded and then converted back to F. 4 1 Link to comment Share on other sites More sharing options...
