SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1141 PM CST Thu Jan 29 2026
Valid 301200Z - 311200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are not expected today or tonight.
...Synopsis/Discussion...
A longwave trough will remain steadfast east of the Rockies, with
upper ridging prevalent over much of the West aside from a few
ridge-riding shortwave troughs over the Pacific Northwest and
Canadian Rockies. Surface cyclogenesis is expected late tonight off
the coastal south Atlantic, with the expectation that convection
will also increase offshore in vicinity of the Gulf Stream overnight
through early Saturday morning. However, it appears that lightning
flash potential will remain limited (less than 10 percent) for the
near-coastal areas of the Carolinas.

Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1241 AM CST Fri Jan 30 2026
Valid 311200Z - 011200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are not forecast across the U.S. on Saturday and
Saturday night.
...DISCUSSION...
An upper-level trough will move through the Southeast on Saturday,
as high pressure settles into the western Gulf Coast states and
Mississippi Valley. Low-level northerly flow will keep a dry and
cool airmass in place over the central and eastern U.S., making
conditions unfavorable for thunderstorm development Saturday and
Saturday night.

Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1135 PM CST Thu Jan 29 2026
Valid 301200Z - 311200Z
...NO CRITICAL AREAS...
...Synopsis...
Fire weather concerns will be minimal across the CONUS today.
Surface high pressure and colder air will filter into areas east of
the Divide. Upper-level ridging will be maintained in the West, but
lack of stronger wind fields and receptive fuels will limit concerns
there.

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1136 PM CST Thu Jan 29 2026
Valid 311200Z - 011200Z
...NO CRITICAL AREAS...
...Synopsis...
A strong upper trough will continue to pivot through the Southeast
on Saturday. A low pressure system will deepen off the East Coast.
While fuels will continue to dry in the West where upper level
ridging will be present, surface high pressure/cold air should
greatly limit fire weather concerns for most areas with drier fuels.
...Southern Georgia into North Florida...
With a low pressure system deepening off the Mid-Atlantic coast,
stronger surface winds will develop behind the cold front within the
Southeast and the Florida Peninsula. Winds of 10-20 mph appear
possible. With cold advection occurring, it is not clear how warm
temperatures will rise or how low RH will fall. There does appear to
be a zone from southern Georgia into North Florida where 25-35% RH
is possible by the afternoon. However, temperatures will still
likely be near 40 F and there is a slight chance for precipitation
as the front moves through late Friday night. Uncertainty is too
high for highlights.
