This hazardous weather outlook is for eastern Utah and western

.DAY ONE...Today and Tonight

Breezy to windy conditions will persist today as a strong upper
level disturbance begins to impact the region. The strongest winds
are expected across areas north of I-70 with the peak gusts
up to 40 mph at lower elevations. Travel may be difficult,
especially for high profile vehicles.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

Breezy to windy conditions will persist into the late week period
under the continued influence of the strong upper level
disturbance. A return to more unsettled weather as well as a
significant cool down is looking probable by late this week as a
cold front treks through the region which should lead to snow
levels lowering in the mountains going into the weekend,
especially further north.


Spotter activation will not be needed.
