SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1224 AM CST Tue Jan 27 2026
Valid 281200Z - 291200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are not expected Wednesday.
...Synopsis...
Upper troughing will continue over the eastern half of the CONUS
Wednesday. Mid-level ridging over the Rockies and Great Basin will
weaken slightly as a subtle mid-level perturbation moves inland from
the eastern Pacific. However, ridging will quickly rebound with the
amplified flow pattern favoring continued northwesterly flow aloft
over the continent. This will reinforce a cold dry and stable air
mass over much of the country. With no inland moisture
return/destabilization, thunderstorm potential is negligible.

SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0231 AM CST Tue Jan 27 2026
Valid 291200Z - 301200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are unlikely Thursday.
...Synopsis...
Broad-scale troughing will continue across the eastern half of the
US as the primary upper trough moves off the East Coast into early
Friday. At the same time several shortwave perturbations, emanating
from southern Canada and the central Rockies respectively, will
begin to converge and strengthen over the central US. In the wake of
these systems, ridging will build over the West supporting continued
strong northwesterly flow aloft. A cold front and Arctic high
pressure will move south forcing offshore flow over the CONUS. This
will again negate thunderstorm potential through the forecast
period.

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0149 AM CST Tue Jan 27 2026
Valid 271200Z - 281200Z
...Synopsis...
Dry post-frontal northwesterly flow across the southern Florida
Peninsula will bring a period of Elevated fire concerns today.
Relative humidity reductions to around 20-25% will overlap with
sustained northwesterly flow around 10-15 mph. Fuels in this region
are critically dry with ongoing drought conditions. The frontal
passage did bring some rainfall across portions of the peninsula but
little to no rainfall occurred across the far southern west coast,
where the Elevated was maintained with this outlook.

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0150 AM CST Tue Jan 27 2026
Valid 281200Z - 291200Z
...NO CRITICAL AREAS...
...Synopsis...
Fire weather concerns are expected to remain low on D2/Wednesday. A
cool and dry air mass will remain in place across much of the CONUS,
with extensive snow pack reaching from the Southern Plains into
portions of the Northeast. Overall, the recent cold and wet pattern
has improved status of fuels in many areas. Some dry conditions will
continue across southern Florida but winds should be lighter,
precluding the need to include any areas.
