Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0945 AM CST Fri Feb 06 2026
Valid 061700Z - 071200Z
...Morning Update...
Elevated fire weather conditions are expected across the northern
Florida Peninsula this afternoon. Relatively light westerly winds
this morning will increase to 10-15 mph with RH falling between
25-35 percent. Despite recent rainfall in the previous days, the
fuelscape remains fairly dry. See the previous discussion for more
information.
..Elizalde-Garcia/Lyons.. 02/06/2026
.PREV DISCUSSION... /ISSUED 0127 AM CST Fri Feb 06 2026/
...Synopsis...
Upper ridging will build over the Plains states as a highly
amplified mid-level trough ejects into the Atlantic today. Surface
high pressure and an accompanying cool airmass will overspread much
of the U.S. from the Plains eastward, limiting significant
wildfire-spread concerns, except over the northern Florida Peninsula
this afternoon. The passage of a surface trough will encourage 10-15
mph sustained westerly surface winds as RH dips into the 25-35
percent range. Given the lack of recent rainfall over northern parts
of the Peninsula, Elevated highlights have been introduced.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0133 PM CST Fri Feb 06 2026
Valid 071200Z - 081200Z
...High Plains...
Downslope winds and unusually dry conditions are expected Saturday
afternoon over parts of CO, WY western NE and northwest KS. RH below
20% and winds gusting to 20-30 mph are likely behind a lee trough
amid unseasonably dry fuels. This will support Elevated fire-weather
conditions for a few hours.
Similar downslope enhanced winds and drying are expected farther
south into parts of West TX and eastern NM. While winds will be
somewhat weaker and more southerly, a few gusts to 20-25 mph and RH
below 20% will still favor Elevated fire-weather conditions.
...FL...
Mid-level subsidence on the back side of the departing eastern US
trough will allow very dry mid-level air to move into parts of FL.
While cooler surface temperatures are expected behind a departing
surface cold front, mixing may allow RH values to fall below 20%
during the day. Occasional gusts to 10-15 mph could support brief
locally elevated fire-weather conditions Saturday afternoon across
the Fl Peninsula. However, cooler surface temperatures and minimal
overlap with dry fuels should preclude broader fire-weather
concerns.
..Lyons.. 02/06/2026
.PREV DISCUSSION... /ISSUED 0139 AM CST Fri Feb 06 2026/
...Synopsis...
Predominantly upper ridging will prevail over the central U.S.
tomorrow (Saturday). However, an embedded mid-level impulse will
traverse the ridge over the central Rockies and overspread the
central Plains by afternoon. Surface lee troughing will encourage
dry downslope flow over portions of the Colorado/Wyoming border into
western Nebraska, and northeast New Mexico into the northern Texas
Panhandle by afternoon peak heating. Over both of these areas, 15+
mph sustained westerly surface winds should overlap with 25 percent
RH for at least a few hours. Given the lack of recent precipitation
over these areas, fuels should be dry enough to support some
wildfire-spread potential, warranting the introduction of Elevated
highlights.
U.S. Day 3-8 Fire Weather Outlook

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0353 PM CST Fri Feb 06 2026
Valid 081200Z - 141200Z
Active and progressive mid-level flow is expected across the CONUS
through the extended forecast period. Shortwave troughing will
progress through the Rockies and Plains this weekend with more
troughing expected later next week. Fire weather concerns
should generally increase for portions of the Southern Plains early
next week as stronger southwest flow affects the region.
...Northern Rockies D3-D4...
Dry and breezy downslope conditions are possible ahead of a northern
stream shortwave trough across parts of the northern Rockies
D3/Sunday and D4/Monday. With westerly flow expected to increase
behind a departing lee low, downslope winds of 15-30 mph are
possible. Uncertainty exists on how dry surface conditions will be
given the arrival of western troughing and snow. However, some
localized fire-weather concerns are possible given ongoing drought
and increase in low-level winds, especially D4/Monday over parts of
WY and CO.
...Southwest/Southern Plains D4-D7...
Increasing mid-level flow over the central Rockies is expected much
of next week as the large-scale pattern moves toward more active
southern stream flow. A shortwave trough will move across the
southern Rockies D4/Monday increasing winds across portions of
eastern NM and west TX. Episodic troughing and stronger flow aloft
will continue through much of the week and into next weekend with an
increase in the fire-weather risk given dry fuels and warm
temperatures.
While some fire-weather risk appears possible, increasing ensemble
member spread and uncertainty regarding the northern extent of
returning Gulf moisture and precipitation into the southern Plains
precludes the introduction of probabilities at this time.
