Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0459 PM CDT Mon Apr 07 2025

Valid 091200Z - 151200Z

An amplifying upper-level wave pattern is expected to develop across
the U.S. beginning day 3/Wednesday with broad ridging over the West
and a deepening trough, cold front intrusion and attendant
precipitation across the eastern U.S. Extended model guidance shows
another upper trough entering the Intermountain West which could
introduce a MULT day fire weather threat to portions of the Desert
Southwest starting on Day 6/Saturday, shifting eastward into the
High Plains by Day 7/Sunday.

...Day 3/Wednesday: Central High Plains...
An area of 40 percent probability for Critical fire weather
conditions including northwest winds of 25 to 35 mph and daytime
relative humidity in the 15 to 20 percent range was introduced into
portions of southeastern Wyoming, northeastern Colorado and western
Nebraska. This is in response to accelerating northwest surface flow
from a strengthening mid-level jet translating over the Central
Rockies and dry fuels.

...Day 6/Saturday - Day 7/Sunday: Desert Southwest and High
Plains...
Upper-level ridging over the western U.S. will bring an extended
period of warm and above normal temperatures to the region aiding in
drying of fuels. An upper-level trough and associated induced
stronger surface wind field combined with a very dry air mass could
bring Elevated to Critical fire weather risks to portions of the
Desert Southwest and High Plains over the weekend (Day 6/Day 7).
However, some inter-model inconsistencies combined with expected sub
prime fuel dryness precludes introduction of Critical probabilities
at this time.
