Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
1153 PM CST Thu Nov 05 2026

Valid 061200Z - 071200Z

...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM PORTIONS OF
THE CAROLINAS TO THE MID ATLANTIC COAST...

...SUMMARY...
Isolated strong to severe storms are possible over parts of the
eastern Carolinas and southern Mid Atlantic Coast.

...Carolinas/Atlantic Coast...
An upper low over eastern Great Lakes at the start of the forecast
period is forecast merge with a shortwave trough moving from the mid
MS Valley across the central Appalachians. A belt of enhanced
deep-layer southwesterly flow will accompany the low across much of
the Eastern Seaboard. At the surface, a cold front and broad area of
low pressure will stretch from southern New England to eastern North
Carolina. The low and front should gradually strengthen as they and
the upper trough move offshore into early Saturday morning.

Early in the period ahead of the cold front, a band of scattered
showers and thunderstorms are likely to be ongoing from southern New
England to the Carolinas, associated with continued northward
advection of mid 60s to low 70s F surface dewpoints. Enhanced flow
aloft will overspread the area through the morning generally
parallel to the advancing front. The strongest upper-level winds
will likely remain on the cool side of the boundary, but model
soundings show effective shear values increasing to 30-40 kt within
the warm sector by late morning.

Given the presence of the unseasonably humid air mass, diurnal
heating and destabilization will tend to be muted by residual cloud
cover, especially with northward extent. Still, cooling mid-level
temperatures and modest buoyancy (MLCAPE ~500 J/kg) should be
sufficient to maintain isolated stronger storms eastward through
midday. Some organization into linear clusters or short bowing
segments is possible which would support a risk for damaging gusts.
Adequate hodograph curvature in the lowest 1-2 km could also support
a brief tornado before convection weakens and moves offshore later
in the afternoon/early evening.

...AZ...
A second upper trough will move from the southern Great Basin into
the Southwest today and tonight. Cold mid-level temperatures will
accompany the upper trough, steeping mid-level lapse rates and
allowing for weak elevated buoyancy to develop. However the limited
instability and vertical shear should preclude a severe risk outside
of sporadic hail with an isolated stronger storm.

Day 1 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
1149 PM CST Thu Nov 05 2026

Valid 061200Z - 071200Z

...NO CRITICAL AREAS...

...Synopsis...
A minimal fire-weather threat is forecast for today owing to a lack
of receptive fuels and relatively calm meteorological conditions. An
exception is the onset of a period of dry and windy conditions with
offshore Santa Ana winds in Southern California this weekend, but
conditions should remain below Elevated criteria for today.

Day 2 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
1150 PM CST Thu Nov 05 2026

Valid 071200Z - 081200Z

...Synopsis...
Elevated fire-weather conditions are forecast across a localized
area of Southern California tomorrow. Portions of the San Gabriel,
Santa Monica, and Santa Susana mountains, along with the San Gabriel
Valley, are forecast to experience a weak to moderate Santa Ana wind
event from late morning into early afternoon Saturday. Sustained
northeasterly off-shore winds of around 20 MPH (gusting to 30-40
MPH) are expected with relative humidity of 15-20%. Current fuels
guidance has ERCs reaching the 90th seasonal percentile for the
region, driven primarily by critically-low 10-hour and 100-hour dead
fuel moisture. Locally Critical conditions are possible where local
terrain favors, and Critical highlights may be introduced if newer
forecast guidance indicates drier or windier conditions than
currently expected.
