Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0252 PM CDT Fri May 26 2017

Valid 281200Z - 031200Z

An upper trough/low should continue moving eastward across the
central/eastern CONUS on Day 3/Sunday, with an upper ridge building
over the western states. This upper ridge should generally remain in
place across the western CONUS through at least Day 5/Tuesday.
Consensus of medium-range guidance suggests an upper trough should
move from the eastern Pacific to the West Coast by Day 6/Wednesday,
possibly undercutting the ridge and becoming closed off across the
Southwest late in the forecast period. Some increase in critical
fire weather potential may occur from Day 6/Wednesday into Day
8/Friday across parts of the southern Great Basin and Southwest with
the approach of the upper trough/low. However, considerable
uncertainty regarding the evolution of this trough/low and
associated enhanced mid-level winds precludes the introduction of
any probabilities at this time.
