Low of only 43 IMBY and 46 now. BWI was down to 37 earlier and 41 now. But there are several PWSs near BWI with temps in the upper 30s currently.

Good catch on the humidity and temp. Not a slam dunk, but definitely suspect. The repaving of the apron at BWI seemed to make a real difference a few years ago. Typically pushed BWI temps closer to DCA vs IAD as before. But the min temp readings the last few weeks have surprised me.
-
That was a record low at BWI and earliest first freeze since 2006.
-
BWI has been colder than MBY I think every or nearly every cool morning since this season. Very big change from previous years. Not sure what has changed…
-
Damn. First freeze at BWI officially. Hit 32.
-
38 at home, BWI down to 34. BWI has been a cold spot this fall. Not sure if that’s random variance or if they adjusted something about the measurements.

BWI hit 35 this morning, which is a typical mark for frost on the ground. I was curious if and how October frost frequency has changed over my life, so here’s the last 40 years. Mean and median days with frost hasn’t actually changed too much (2-3 days for both), but the months with numerous frosts haven’t been since in a couple decades. 2024 is month to date.

Surprised to see some frost on neighborhood rooftops
-
That stopped. Only 39. Meh.
-
Radiating well. Down to 44 already.
-
Sky cleared up nicely.

West. Above the setting sun

Once I found it, I could see it naked eye as a long faint smudge. iPhone exposure was 2-3 seconds.
-
Down to 40 at 2am and then slightly warmed toward dawn.
-
Finally saw comet atlas
-
Pretty sunset clouds

Frost advisory for northern MD
-
Colors have popped a lot in the last 5 days. I’d expect them to continue changing quickly this week with cool weather. Just seems leaf drop is happening almost as quickly as they change color
-
This clearly got slowed down by 4-6 hours
-
On paper, easiest stretch of the schedule coming up. Need to take care of business.
-
Front goes through around 7-10z tomorrow morning west to east. Our first midnight high of the season for tomorrow??

Good game Commies. Daniels is legit.
