This Hazardous Weather Outlook is for Western and Central Wyoming.

.DAY ONE...This Afternoon and Tonight.

Another round of scattered showers and thunderstorms returns with
gusty outflow wind 35 to 45 mph being the primary hazard. Coverage
is greatest between 1 PM and 6 PM, especially along and east of the
Continental Divide, before coverage and intensity decreases by 10 PM.
Elevated fire weather conditions may be possible over portions of
southern Wyoming through 8 PM, due to low relative humidity and gusty
surface wind, including those from showers and storms.

.DAYS TWO THROUGH SEVEN...Sunday through Friday.

Sunday and Monday...Daily chances for afternoon showers and
thunderstorms. The best chances will be in central and northern
Wyoming with lesser chances elsewhere. Low minimum relative humidity
and breezy westerly wind persists across southern Wyoming. These
conditions are expected to gradually spread north leading to elevated
to near-critical fire weather conditions to start the week.

Tuesday through Friday...The combination of gusty westerly wind,
above normal temperatures, and low relative humidity will create
elevated to perhaps critical fire weather conditions across portions
of southwest and central Wyoming.

.SPOTTER INFORMATION STATEMENT...

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