.DISCUSSION...
A low level jet will impart south-southeast winds overnight. Peak
wind gusts to 30 mph possible, peaking shortly before midnight.
Shower activity from storms to the southwest over Colorado may
persist overnight to pass over the site. No wetting rainfall
is anticipated from these showers, but could improve overnight
humidity recoveries. Forecasted recoveries are good at around
90%. Tomorrow winds shift out of the southwest to west in the late
morning and early afternoon hours. A few showers may be possible
in the afternoon but confidence in wetting rainfall is low.
