Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0104 AM CST Mon Feb 19 2018

Valid 191200Z - 201200Z

...Synopsis...
An upper-level trough over the West will shift eastward today as a
midlevel speed max moves through the base of the trough. This
pattern will continue to support strong southwesterly flow aloft
over the southern High Plains.  In response at the surface, a
strengthening low pressure system will develop over Colorado during
the afternoon hours.

...Portions of the Southern High Plains...
An increasing surface pressure gradient coupled with downward
vertical mixing of high momentum air from aloft will contribute to
windy conditions today across much of the Southwest and southern
High Plains.  While sustained afternoon wind speeds will exceed
critical thresholds across the region (30 mph across southeastern
Colorado/northeastern New Mexico decreasing to 20 mph farther east
into western Oklahoma), RH values are expected to remain above
critical thresholds (generally at or above 25%).  Nevertheless, fire
weather conditions will be elevated given the ongoing drought,
dry/dormant fuels, and strong winds across the region.
