Stick a Fork In It

A Freeze Warning is in effect for 1am to 7am tomorrow morning.

Now

Cold. Put away the lawnmower, get out the rake or leaf blower, stick a fork in it, this growing season is about to be declared officially done. Lows last night were 35° at National, 32° at Dulles, and 33° at BWI; temperatures below freezing are likely tonight throughout the Washington metro area. Under northwesterly breezes, temperatures this afternoon have struggled even to make it into the upper half of the 40s, more typical of the average daily highs in mid December. The official high at National was 46&deg.

Tonight and Tomorrow

Freeze Warning. With clear skies and light winds, lows tonight should be near 30° downtown to the lower 20s in some outlying areas. Tomorrow will again be sunny with highs a little warmer, near 49°.

It is described by the publisher as "a balanced and comprehensive guide to global warming, covering the science, the symptoms and the solutions."
