Day 1 Fire Weather Outlook

1259 AM CDT Fri Sep 20 2019
Valid 201200Z - 211200Z
...CRITICAL FIRE WEATHER AREA FOR THE FOUR CORNERS REGION...
A highly amplified upper-level trough positioned over the Great
Basin will shift east through the Northern Rockies into portions of
the central/northern Plains. Enhanced mid-level flow of 60-70 kt
will be present within the base of the trough during this
progression. At the surface, a broad region of dry and breezy
southwesterly winds will develop during the afternoon beneath the
...Four Corners Region and portions of the central Rockies and
central High Plains...
Sustained winds of 15-25 mph will develop during the afternoon while
RH values fall into the 15-20% range over much of the region. Fuels
remain receptive to large-fire spread, and thus, elevated to
critical fire-weather conditions are possible. Refinements were made
to the existing elevated area over portions of the central High
Plans and central Rockies, based on the position of moist boundaries
as depicted in the latest high-resolution guidance. A critical area
was added near the Four Corners region, where it appears most likely
that critical wind/RH thresholds will be exceeded for a few hours
during the afternoon.
