Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1054 AM CST Thu Feb 05 2026
Valid 051700Z - 061200Z
...Montana High Plains...
Stronger northwest flow aloft along with surface troughing across
the northern High Plains will continue to support elevated
west-northwest winds of 10-15 mph (locally 20-25 mph in favored
terrain gaps) across the northern High Plains of MT. Downslope
drying in the lee of the Northern Rockies will promote afternoon
relative humidity in the 15-20% range across the area, with current
relative humidity observations already nearing 20%. Several days of
above normal temperatures and persistent dry conditions have allowed
a more receptive fuelscape to develop. Elevated highlights were
added to the snow-free lower elevation areas of central MT.

.PREV DISCUSSION... /ISSUED 1249 AM CST Thu Feb 05 2026/
...Synopsis...
A highly amplified upper-level pattern will be in place today.
Ridging will dominate the West with troughing in the East. While
fire weather concerns will generally be low, some modestly dry and
breezy conditions are possible within a weak downslope flow regime.
These conditions will occur within the lee of the northern Rockies
extending into portions of the central High Plains. There are some
drying fuels in these areas that could allow for localized elevated
fire weather. RH will range from 15-25% with winds around 15 mph
(locally greater).

U.S. Day 2 Fire Weather Outlook

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1250 AM CST Thu Feb 05 2026
Valid 061200Z - 071200Z
...NO CRITICAL AREAS...
...Synopsis...
With the upper-level ridge becoming more expansive across the CONUS,
fire weather concerns are expected to remain low for most areas on
account of relatively weak winds. There will be pockets of
dry/breezy conditions in north/central Florida, but recent and
expected precipitation should keep any fire weather concerns
localized at best.

U.S. Day 3-8 Fire Weather Outlook

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0357 PM CST Wed Feb 04 2026
Valid 061200Z - 121200Z
...Synopsis...
The highly amplified upper ridge over the West will begin to break
down through the weekend while troughing across the eastern U.S.
shifts eastward. Troughing becomes established across the West next
week, providing some opportunities for precipitation and cooler
temperatures across the region and High Plains. A cut-off low
meanders eastward through Mexico into the Southern Plains by Day
6/Monday while surface high pressure pushes farther into the
Atlantic from the Southeast. This will aid in deeper boundary layer
moisture return, which should mitigate fire weather concerns across
the Southeast and FL next week. Stronger westerly flow aloft
attributed to the breakdown of the upper-level ridge and more
pronounced lee surface cyclogenesis in the Plains could elevate the
fire weather threat across the central and southern Plains Days
6-7/Monday-Tuesday of next week.
...Days 3-4/Friday-Saturday - Southeast and Florida...
Fairly widespread rain showers along a cold front moving through the
Southeast and FL through Day 2/Thursday should temporarily mitigate
fire weather concerns across much of the region before dry,
post-frontal flow commences on Day 3/Friday. However, drier pockets
of fuels could remain across northern FL, where recent fire activity
has been observed within a drought stressed fuelscape. Uncertainty
in the near-term precipitation distribution across Florida precludes
introducing critical probabilities at this time.
...Day 4/Saturday - Southern and Central High Plains...
A mid-level short wave within broader northwesterly flow aloft is
expected to reach the Northern Plains by Day 4/Saturday. Subsequent
lee cyclogenesis across the northern/central Plains should bring
increasing westerly to northwesterly winds to much of the northern
High Plains. This region remains mostly snow free, with fuels
continuing to dry under unseasonably warm temperatures. Although
breezy winds are expected, RH reductions are uncertain, likely
remaining above 20% based on latest model guidance.
Farther south, lower RH amid warmer temperatures across southeastern
WY, northeastern CO and far western NE should align with breezy
winds and dry fuels to bring an enhanced fire weather threat to the
area Saturday. Marked southwest flow and downslope drying south of
the evolving surface low/trough could support an additional fire
weather threat across portions of northeastern NM and the TX
Panhandle where drier fuels are expected to emerge. 40% critical
probabilities were added to these areas.
