Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0134 AM CST Mon Jan 19 2026
Valid 191200Z - 201200Z
...NO CRITICAL AREAS...
...Synopsis...
Fire-weather concerns are generally low across the CONUS today. The
one exception will be across parts of central into southwest FL,
where dry post-frontal conditions are expected during the afternoon.
A brief overlap of around 10 mph sustained northerly surface winds
and 20-30 percent RH may yield locally elevated fire-weather
conditions.

U.S. Day 2 Fire Weather Outlook

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0134 AM CST Mon Jan 19 2026
Valid 201200Z - 211200Z
...Synopsis...
Embedded within a belt of enhanced northwest flow aloft, a midlevel
impulse and related jet streak will overspread the northern/central
Rockies and adjacent High Plains during the afternoon. At the same
time, an accompanying surface low will track southeastward along the
northern/central High Plains.
This will result in a tightening pressure gradient and 20-25 mph
sustained northwesterly surface winds (with higher gusts) across
parts of the central High Plains. The combination of these winds and
around 15-20 percent RH will favor elevated to locally critical
fire-weather conditions. Preceding snowfall in the vicinity
(especially along the southern flank of the Elevated area) does cast
some uncertainty on the overall fire risk, and fuel trends will be
monitored for future adjustments to these highlights.

U.S. Day 3-8 Fire Weather Outlook
ZCZC SPCFWDD38 ALL

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0325 PM CST Sun Jan 18 2026
Valid 201200Z - 261200Z
...Synopsis...
Large scale upper-level troughing is expected to persist across the
eastern U.S. through midweek while drier and above seasonal warmth
under ridging is expected across much of the West. Longer term model
guidance suggests a breakdown of the persistent ridge across the
northeastern Pacific, inviting an upper-level trough into the
Southwest by the weekend while a cold front transfers a much colder
air mass into the eastern U.S. Widespread precipitation attributed
to the upper trough and surface cold front across the Southwest,
Southern Plains and Southeast should mitigate fire weather concerns
over the weekend into early next week.
...Day 3/Tuesday - Central High Plains...
An upper-level short wave moving into the central/southern Rockies
within broad northwest flow aloft and attendant lee cyclone
development in the central High Plains on Day 3/Tuesday could bring
a brief fire weather threat to portions of the central High Plains.
Snowfall preceding this downslope-enhanced event on Day 2/Monday
could mitigate fire weather concerns for much of north-central and
east-central CO into western KS. The most likely snow-free area will
be across far northeastern CO into the southwest NE, where recent
fire activity has occurred and receptive fuels remain. Introduced
40% critical probabilities for this area within a zone of stronger
west-northwest winds, low relative humidity and seasonably warm
temperatures.
