New Record Low Temperature for Chico

19record_low.jpg

This still image above from my Bidwell Ranch weather station at 10:30 this morning.

The cold air mass that originated in Siberian Polar regions made its way into Northern California yesterday, and as winds died last night, the temperature plummeted in the still unmixed air. The new record low for this date is 19 degrees, besting the old record of 22 degrees set in 1963.

More record cold is expected tonight. We could see 16 degrees in the outlying areas and 20 in the City.

the most current forecast from my automated forecast system is available here

Note that the record high for this date was 76 in 1920.

The hottest temperatures on recrod wordlwide are available at the NOAA NCDC Climate Center

What I find most interesting is the fact that none of the hottest temperatures worldwide have occurred during the 1998-2006 period of hot weather that many claim is the beginning of irreversible global warming. In fact they mostly occurred in the early and mid 20th century.

And its not just Chico that set new records lows overnight.
