Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0331 PM CDT Thu Mar 22 2018

Valid 241200Z - 301200Z

A prolonged period of elevated to critical fire weather conditions
is expected across portions of the southern Rockies and the
central/southern High Plains. Enhanced southwesterly deep-layer flow
will be entrenched over the region through at least Day 5/Monday,
and possibly longer, as an amplified eastern upper ridge blocks the
progression of large-scale trough over the western U.S. A weak lee
trough will develop on Day 3/Saturday, resulting in breezy and dry
downslope winds. By Day 4/Sunday, a stronger lee cyclone is expected
to develop over eastern CO and stronger winds will overspread the
region in conjunction with persistent dry conditions behind a
surface dryline. Elevated to critical conditions should persist into
Day 5/Monday as the lee cyclone tracks east/southeast into KS/OK.

Beyond Day 5/Monday confidence wanes with varied guidance with
regards to the evolution of the western trough. Some fire weather
potential could persist across portions of the southern
Rockies/southern High Plains on Day 6/Tue before the western trough
finally begins to slowly migrate eastward by the end of the period.
