Type in your town, state or zip code.
Then on the Weather Report line go to Historic averages.
It will bring up months, highs and lows, averages for those dates.
Click on the month you want to see and it will give these readings for each day of the month.
I right now show us to be having a normal cold winter based on readings for the last 60 years.
Great link, thanks!
