...Synopsis...
Fire weather concerns are expected to remain low across the CONUS
today. The western US trough will begin to move into the southern
Rockies, with a front bringing rainfall extending into the central
Plains/Midwest. Dry and warm conditions are expected across the
Southeast in association with the eastern US high. Generally light
surface winds will keep fire concerns low despite a few areas with
lower afternoon relative humidity amid dry fuels.

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0437 PM CDT Sat Oct 24 2026
Valid 261200Z - 011200Z
...Synopsis...
A series of mid/upper short waves will lift northeastward from the
central and northern Rockies into the Plains, Upper Midwest and
Great Lakes through Day 6/Thursday as a ridging pattern maintains
over much of the eastern U.S. A robust mid-level jet over WY and an
evolving surface low across the northern Plains will contribute to
downslope drying and stronger westerly winds across eastern WY on
Day 4/Tuesday, although cooler temperatures and precipitation
preceding this wind event on Day 3/Monday could reduce overall fire
weather threat.
Fuels continue to degrade within the lower MS River Basin as severe
to extreme drought slowly expands under persistently dry conditions.
Although receptive fuels exist, a light wind regime under a ridging
pattern and weak surface pressure gradients will limit fire weather
concerns through much of the week. Northeast to east wind
trajectories will keep deeper atmospheric moisture towards the Gulf
Coast resulting in low daytime RH each day across much of the
interior Deep South. Longer term ensemble guidance suggests a return
of more established and deeper troughing across the West while
ridging remains over the eastern CONUS but fire weather concerns are
likely to remain subdued.
