Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1036 AM CST Mon Jan 19 2026
Valid 191700Z - 201200Z
...NO CRITICAL AREAS...
...Florida Panhandle...
Dry, post-frontal northerly to northeasterly surface winds of 10 mph
(15 mph locally) across FL coinciding with RH reductions in the
20-30% range will yield an increased fire weather concern over the
western/southwestern FL Panhandle through the afternoon. However,
cooler temperatures and marginally receptive fuels should limit a
more significant fire weather threat.

.PREV DISCUSSION... /ISSUED 0134 AM CST Mon Jan 19 2026/
...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.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0152 PM CST Mon Jan 19 2026
Valid 201200Z - 211200Z
...Central High Plains...
An approaching mid-level wave and associated increasing northwest
flow aloft, coinciding with a deepening surface low in the lee of
the Southern Rockies will support downslope enhanced west/northwest
surface winds across portions of the central High Plains Tuesday.
Only minor changes were needed to the existing Elevated highlights
across far northeastern CO, extreme southeastern WY, southwestern NE
and far northwestern KS to account for recent snowfall from the CO
Front Range into western KS. Farther south, downslope enhanced
drying and warming should result in relative humidity as low as 10
percent Tuesday. This aligned with sustained west winds of 15-20 mph
and dry fuels will support at least elevated fire weather conditions
for several hours in the lee of the Sangre De Cristo Range. Locally
critical conditions are possible where wind speeds of 25 mph develop
in favored terrain gaps. Thus, Elevated highlights were introduced
across portions of south-central CO.
..Williams.. 01/19/2026
.PREV DISCUSSION... /ISSUED 0134 AM CST Mon Jan 19 2026/
...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

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0341 PM CST Mon Jan 19 2026
Valid 211200Z - 271200Z
...Synopsis...
Reduced fire weather concerns are expected across CONUS through
early next week. An arctic air mass intrusion begins Day 4/Thursday
across the Northern Plains as upper-level troughing impinges on
coastal California. The upper-level trough moves into the Southwest
and Southern Plains by Day 5/Friday, interacting with deeper Gulf
moisture to support expansive precipitation across much of the
Southern U.S. through the weekend as the trough translates eastward.
The lingering cold and stable air mass across the eastern U.S. along
with likely widespread rain and potential snow over much of the
Southern U.S. should mitigate the overall fire weather threat
through early next week.
