temperature

We are getting frosted morning tomorrow. According to weather report, temperature will be low to 38F.

Man, that's FROST, in May 4th. Are we in Siberia?

And we had a 70F warm & humid day around December 20th, 2010. I don't remember exactly which day that was. There was tornado warning that day.

Excess of snow this winter, latest snow fall in April when the temperature was around 80F.

What's happening there?
