Normal freeze date for IAD isn't until November, IIRC.

IAD is actually like Oct 20? BWI around Nov 1 and DCA in mid January.

Nice! Got sounding data to post?

Unfortunately I don’t think I’ll be able to get my hands on it. Though next semester when I’m in lab for the class I’ll have access to it and will use it to create a scew T diagram!

There's been some epic fall mornings here in the lowlands the past several days. This weather has been amazing.

In 1993, IAD had a freeze on October 1. I was working a temp job in a building on Avion Parkway right next to the airport, and all the grass was white with frost.

Thank you for the info, IAD seems to be an ice box compared to the other climate sites.

Should be a fun night in the mountains of Washington State.  Perhaps they will get more snow tonight and tomorrow than what we will see in 2+ years.  I remember being up there in September a few years ago near Leavenworth, WA and there was snow/sleet with accumulation at some higher elevations.
