Day 2 Fire Weather Outlook

Valid 291200Z - 301200Z

A departing mid-level trough will aid in sustaining breezy northwest
winds of 15-20 mph across the Interstate 80 corridor in southwest
Wyoming Sunday. The winds overlapping with relative humidity in the
15-20 percent range amid a very dry fuelscape will support elevated
fire weather conditions across southwest Wyoming.  Otherwise, fire
weather concerns across much of the western U.S. will be mitigated
by a building upper-level ridge bringing warming temperatures and
generally light, terrain-driven winds.

...Synopsis...
Upper ridging is forecast to steadily build over the West Coast
Sunday, as weak troughing shifts eastward. As heights continue to
rise, weakening the flow aloft over the northern Rockies, a cold
front will move out of the Northwest ushering in a cooler and higher
humidity air mass. Some residual mid-level flow will linger across
WY and western CO Sunday, but surface winds are expected to be much
weaker and will shift to northwesterly. The weaker winds, along with
increasing humidity should limit broader fire-weather potential.
Some localized dry and breezy conditions will remain possible over
southwest WY, but widespread fire-weather concerns are not expected.
