Long Term Winter Weather Forecast, 2012/13
This may be of interest -- good news for those of us who are tired of putting up frost cloth in the Desert (but our water bills might be higher) :-)
From the NWS:
The December, January, February (DJF) 2012-13 temperature outlook indicates enhanced chances for above normal temperatures for much of the western continental U.S. stretching across the south central great plains to the western gulf coast. Below normal temperatures are favored for parts of the northern Great Plains and western great lakes and the Florida peninsula. For Alaska, there are elevated odds for above-normal temperatures along the North Slope and below normal temperatures for the southeast and Alaska panhandle.
The DJF 2012-13 precipitation outlook favors above-average precipitation for an area in the Tennessee valley and below-average precipitation for parts of California, Nevada, Southeast Alaska and the Alaska panhandle.
In locations where the likelihoods of seasonal mean temperatures and seasonal precipitation amounts are similar to the climatological probabilities, equal chances (ec) of below, near, and above-average temperature and precipitation are indicated.
Any questions, just ask.
