Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1136 AM CDT Fri Oct 30 2026
Valid 301700Z - 311200Z
...NO CRITICAL AREAS...
The upper pattern is categorized by broad upper troughing over the
western CONUS, prevailing northwest flow from the Upper Midwest into
the Mid-Atlantic, and a mid-level ridge over the Southeast.
Widespread precipitation is expected today across the Greater Four
Corners region into the Great Plains, while dry conditions will
linger for one more day in the Mid-South amid light surface winds.
As a result, fire weather concerns are reduced across the CONUS.

Fire-weather concerns will remain minimal across the CONUS today,
given widespread precipitation and a limited overlap of dry and
windy conditions.

Day 2 Fire Weather Outlook

Valid 311200Z - 011200Z
...NO CRITICAL AREAS...
Fire weather concerns will remain low across the CONUS on Day
2/Saturday. A low-amplitude shortwave trough will lift out of TX
into the Mid-South/Southeast with embedded tropical remnants and
Gulf moisture pervading much of the region. Impulses within
southwesterly flow aloft will promote scattered showers where dry
fuels exist in the lower MS River Valley, bringing some relief to a
drought-stressed fuelscape.

...Synopsis...
A limited overlap of dry and windy conditions atop receptive fuels
will keep fire-weather concerns minimal across the CONUS on
Saturday.

Valid 011200Z - 071200Z
...Discussion...
A high amplitude trough will slide eastward over the Great Basin on
Day 3/Sunday, keeping the western half of the CONUS under increased
cloud cover, below-normal temperatures, and periodic precipitation.
Farther east, a mid-level ridge will temporarily build over the
ArkLaTex ahead of the aforementioned trough, promoting slightly
above-normal temperatures. Persistently dry conditions will finally
come to an end in the Southeast as surface high pressure diverges to
the Eastern Seaboard, allowing chances of accumulating precipitation
and higher surface RH (greater than 40%). As the amplified trough
progresses, it will deliver cooler-than-normal temperatures and
another round of widespread precipitation across much of the CONUS
early next week. Thus, any threat of significant fire weather
remains low and will trend even lower by next week in almost all
CONUS locations.
