It has been ridiculously cold in Philadelphia this month, with afternoon temperatures among the coldest on record. I’m looking out the window watching snow falling.
Nighttime March temperatures have been declining in Pennsylvania since the 19th century.
And the likelihood of cold nights has been increasing since the 19th century.
It is cold here again today, but on this date in 1910 Philadelphia was 82 degrees, and more than half of the US was over 70 degrees. CO2 was 300 PPM at the time.
March 25 afternoon temperatures have dropped more than 10 degrees in Pennsylvania since the 1920’s.
The climate is always changing but the weatherman does not know why!
@tonyheller, thank you for UNHIDING.zip, works great on win.
I’m using date_range=0321:0920 (first equinox semester) but ghcn.py does not handle date_range=0921:0320 (the other equinox semester) in the result ?
It can’t go across year boundaries.
@tonyheller (March 25, 2018 at 4:24 pm), thanks. Now using option months= but the Average-Daily-Temperature-Range appears same for:
– ghcn US.txt months=10 11 12 1 2 3
– ghcn US.txt months=4 5 6 7 8 9
What can I do? Is ghcn.exe (13. August 2017, 21:02:30), downloaded as advised , still current.
It’s the politicians and their hot air.

This morning we tied the record low temperature for this date in WV, but it doesn’t show up at the above website.
