Saturday. Temperatures will be 15 to 20 degrees above normal. Daytime 

heating will drive upslope/up-valley winds (generally out of the 

southeast) while increasing southerly flow aloft will bring gusty winds

to ridgelines, especially on Saturday. The next chance for showers at

the burn site will come Sunday and Monday.
