Autumn/Fall 2015 Thread (Northern Hemisphere, Sep-Nov) (snow, warm, ice, average)

[ral31]

It looks like it got down 36F at the airport this morning, but I noticed a few patches of frost on roofs in my neighborhood.

Tonight is supposed to be even cooler at 29F. Today's high is 52F and sunny.

There is a very light dusting of snow on the roof.

It irks me when "normal" is used rather than "the long term average", especially in regards to weather. Especially with something as variable as snow, rain or drought.

I should start a topic.

You must of had some snow showers over night and was cold enough to stick around. LEX at 6am had "unknown precip" so looks like there was moisture around as snow maybe graupel.

Not sure if you guys will like this site, just came across it. Wind Chill Map. Where is the legend though? That should be a given to anyone creating these.

Anyway. Feels like 30s down south almost lunchtime.
