Day 3-8 Fire Weather Outlook 
NWS Storm Prediction Center Norman OK
0518 PM CDT Fri Nov 01 2024

Valid 031200Z - 091200Z

A mid-level trough will deepen across the Interior West on Sunday
and will de-amplify while ejecting into the Mississippi Valley by
mid-week, when another mid-level trough will amplify across the
western U.S. As both mid-level troughs amplify, surface high
pressure will build across the Interior West as surface cyclone
development takes place across the Plains on Sunday and mid-week.

On Days 3 and 6 (Sunday and Wednesday), medium-range guidance shows
deep-layer northwesterly flow overspreading California as the
backside of the mid-level trough coincides with a surface pressure
gradient across the state. Dry and breezy conditions may occur
across northern parts of the northern California Valley region,
though questions regarding marginal RH dips and fuel receptiveness
preclude Critical probabilities in this region. Locally dry and
breezy conditions may also occur over the higher terrain-favoring
areas around the Los Angeles area Sunday evening into Monday
morning. However, the relatively greater threat for dry offshore
surface flow in this region may occur on Day 6/Wednesday, when a
stronger surface gradient may develop, necessitating the
introduction of 40 percent Critical probabilities.
