.DAY ONE...Today and tonight.
Showers and thunderstorms are expected to develop throughout the day

east of the Divide. Daytime heating and above normal moisture will be
capable of fueling the development of a few strong to severe
storms. The main hazards as a result of any strong to severe storms
will be large hail, strong gusty winds, and heavy downpours. Isolated
flash flooding will be possible with any showers or storms. Showers
and storms will start to gradually dissipate by the late evening
into the early morning hours Thursday.
.DAYS TWO THROUGH SEVEN...Thursday through Tuesday.
Thursday through Monday...Daily chances for afternoon showers and
thunderstorms. The best chances will remain over central and northern
WY with lesser chances elsewhere. Periodic heavy downpours will be
possible with any showers or thunderstorms that develop.
Precipitation chances will decrease through the weekend becoming more
focus across northern WY. Low min RH and breezy winds will develop
across southern WY. This may lead to elevated or near critical fire
weather conditions through the weekend.

Weather spotters are encouraged to report significant weather
conditions according to Standard Operating Procedures.
