weather across the area today. A clipper will dive down east of
the Continental Divide this afternoon and evening, and this should
bring a boost to the normal N-NE drainage/downslope winds across
the area after sunset.

Temperatures will continue to trend higher, RH lower on Thursday
as a ridge strengthens over the area; winds will be light with
mountain/valley diurnal flows prevailing.

...Thunderstorms imply strong gusty and erratic winds...
