Day 1 Fire Weather Outlook

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.

...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).

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0134 PM CST Thu Feb 05 2026
Valid 061200Z - 071200Z
...NO CRITICAL AREAS...
No changes to the Day 2 Fire Weather Outlook. Post-frontal dry and
breezy conditions including west winds of up to 15 mph, along with
minimum relative humidity in the 30-35% range are expected across
northeastern FL Saturday. However, recent rainfall from a cold front
will temporarily mitigate fire weather concerns across much of the
FL peninsula for Friday. Isolated areas that received less than a
tenth of an inch of rain could harbor more receptive fuels, but a
broader fire weather concern has been reduced.
..Williams.. 02/05/2026
.PREV DISCUSSION... /ISSUED 1250 AM CST Thu Feb 05 2026/
...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
0353 PM CST Thu Feb 05 2026
Valid 071200Z - 131200Z
...Synopsis...
A gradual breakdown of the highly amplified ridge across the western
U.S. is expected through the weekend, with troughing becoming more
established across the West by the middle of next week. An embedded
mid-level short wave within the devolving ridge along with deepening
lee surface troughing across the central/northern Plains will
present an increased fire weather threat across portions of the
central and southern Plains on Day 3/Saturday. Fire weather concerns
could persist for portions of the Southern Plains early next week as
surface troughing and subsequent stronger southwest flow affects the
region.
...Day 3/Saturday...
Dry and breezy conditions within a favorable downslope regime are
likely across portions of the central High Plains Day 3 Saturday,
where westerly winds align with low RH and persistently dry fuels.
Farther south, dry southwest flow south of a deepening lee surface
trough across the central Plains should support a fire weather
threat to portions of northeastern NM and the TX Panhandle. 40%
critical probabilities were maintained for these areas for Saturday.
An exiting mid-level trough and dry, post-frontal flow is expected
across the Mid Atlantic/Carolinas region Saturday. However, recent
precipitation and colder temperatures should mitigate a more
significant fire weather threat.
...Day 5/Monday - Southern High Plains...
Fire weather concerns could linger across the southern central High
Plains into early next week as surface lee troughing expands across
the central Plains in the shadow of increasing mid-level flow over
the central Rockies. However, increasing ensemble member spread and
uncertainty regarding the northern extent of return Gulf moisture
into the southern Plains precludes introduction of critical
probabilities at this time.
