Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
1248 AM CDT Tue Oct 20 2026

Valid 201200Z - 211200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
No severe thunderstorms are forecast across the U.S. today and
tonight.

...DISCUSSION...
A mid-level anticyclonic flow pattern will be in place across the
south-central U.S. today, as divergent flow aloft remains over the
Southwest. At the surface, a large area of high pressure will be
entrenched over the eastern half of the nation. An axis of low-level
moisture will be in place over the Desert Southwest, where scattered
thunderstorms will be possible today as instability increases. The
chance for storms in the Desert Southwest will continue into the
evening and overnight period. No severe threat is expected across
the continental U.S. through daybreak Wednesday.

Day 1 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
1251 AM CDT Tue Oct 20 2026

Valid 201200Z - 211200Z

...NO CRITICAL AREAS...

...Synopsis...
Fire weather concerns will remain low across CONUS today. An
upper-level low in the northeast Pacific will push southward  today
but remain offshore from the CA Central Coast through tonight.
Increasing southwest flow ahead of this low will promote a broad
diffluent pattern over the Southwest while ushering in increasing
cloud cover and Pacific moisture into the region. This should
mitigate significant fire potential. Surface high pressure
encompassing much of the eastern U.S. will provide seasonable
temperatures and dry conditions across the region, including minimum
daytime RH around 20% in parts of the Deep South. Although drought
stressed fuels remain across parts of the Deep South, weak surface
pressure gradients will promote light afternoon winds reducing the
overall fire weather threat.

Day 2 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
1256 AM CDT Tue Oct 20 2026

Valid 211200Z - 221200Z

...NO CRITICAL AREAS...

...Synopsis...
Fire weather concerns will remain low across CONUS D2/Wednesday. 
An upper-level low will move onshore into the CA Central Coast
Wednesday and Wednesday night ushering in expanding cloud cover and
precipitation into CA, the Great Basin and the Four Corners region.
Stagnant surface high pressure across the eastern U.S. in addition
to an amplifying ridge aloft over the Great Plains will bring
continued dry conditions to the Deep South. Receptive fuels will
persist across the lower MS River Valley while further drying of the
fuelscape occurs portions of the Southeast. However, surface winds
are expected to be rather light at 10 mph or less which should
reduce the overall fire weather threat.
