Valid 101200Z - 111200Z
...NO CRITICAL AREAS...
...Synopsis...
Fire weather concerns are expected to be minimal today across the
CONUS. A trough will traverse the Great Lakes region, with cooler
and wetter conditions extending from the Upper Midwest into the Ohio
River Valley and up to the Northeast. Cooler post-frontal conditions
will extend across much of the Plains. Some briefly Elevated
conditions are possible in the Northeast ahead of the approaching
front, but wetting rainfall will be expected by the afternoon.
Lingering dry conditions will be possible across southern
California, but generally light winds will keep fire concerns low.

Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1219 AM CST Sun Nov 10 2024
Valid 111200Z - 121200Z
...NO CRITICAL AREAS...
...Synopsis...
A trough will move inland across the western US on Monday, bringing
enhanced westerly flow aloft across the Great Basin in addition to
potential for rain/snow showers. An increase in southwesterly
surface winds will overlap dry conditions across portions of
southern Nevada. Though relative-humidity reductions to around 15-20
percent are likely with sustained winds 10-15 mph (gusting higher),
fuels in the region are largely unreceptive to fire spread. This
will preclude the need to include probabilities at this time.

Day 3-8 Fire Weather Outlook

0157 PM CST Sat Nov 09 2024
Valid 111200Z - 171200Z
Generally speaking, fire weather concerns will be low this upcoming
week. A fairly progressive mid-level flow will bring another
mid-level trough across the eastern United States by midweek,
ushering in a cooler airmass. Areas where critically low relative
humidity may eventually overlap critically high wind include
portions of the Great Basin as the aforementioned trough moves
through. However, fuels should not be overly receptive. Elsewhere,
longer-range guidance indicates a potential return of strong,
northerly flow across southern California as another deep low
develops across the Great Basin. This may result in an off-shore
wind event next weekend -- just outside this forecast period.
