.DISCUSSION...
Near by convection may produce gusty outflow winds and frequent
lightning. Showers may drift over the Fair later this evening,
though embedded thunderstorms are more likely to hug higher terrain.
Expect clearing conditions after 9 PM MDT with another round of
afternoon convection possible tomorrow by mid- afternoon and carrying
into evening hours. Heavy rain, frequent lightning and gusty outflow
winds are possible with stronger storms Saturday. This will increase
the concern for minor, localized flooding.
