This hazardous weather outlook is for eastern Utah and western
Colorado.

.DAY ONE...Today and Tonight

Drier air pushing in from the north will result in a reduction in
storm coverage compared to previous days. Storms are expected to
develop over the high terrain this afternoon with better coverage
across southeast Utah and southwest Colorado where localized
flooding is possible due to heavy rain. Elsewhere, gusty outflow
winds and lightning appear the main concerns with storms.

.DAYS TWO THROUGH SEVEN...Monday through Saturday

Drier air moving in from the north will result in a gradual
reduction in storm coverage through mid week with gusty winds more
of a concern than heavy rain. Storms still develop over the high
terrain each afternoon despite less coverage and drier air.
Potential exists for moisture to increase late this week,
resulting in more widespread storm coverage.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed.

This Hazardous Weather Outlook is for Western and Central Wyoming.

.DAY ONE...Today and Tonight.

Very isolated rain showers and thunderstorms this afternoon into this
evening. Gusty wind will be the predominant weather threat.

.DAYS TWO THROUGH SEVEN...Monday through Saturday.

Isolated to scattered thunderstorms will occur each afternoon. No
severe weather is expected at this time, but gusty wind, frequent
lightning, and brief heavy rain are all threats with any storms that
develop. From Wednesday onward the heat will return. Fire weather
concerns remain high, especially due to the possibility for fire
starts from lightning and very low relative humidity heading into
next week. Thursday looks like it will feature the highest fire
weather concerns of the period due to increased wind ahead of a
weather system.

.SPOTTER INFORMATION STATEMENT...

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