   Valid 291200Z - 301200Z

   ...Synopsis...
   ...Southern California...
   Surface high pressure expanding across the Great Basin as an upper
   low moves into the Southwest will maintain dry, breezy offshore flow
   across parts of southern CA on Tuesday. Northerly winds of 15-20
   mph, with gusts to 30-45, are possible in wind-prone areas across
   southern Santa Barbara County and the mountains and foothills of
   Ventura and Los Angeles Counties. RH of 15-20 percent, combined with
   increasingly dry fuels, will support elevated fire-weather
   conditions. 

   ...North-central Montana...
   Increasing westerly flow aloft and a tightening surface pressure
   gradient across the northern Rockies/High Plains will promote
   breezy, downslope winds across north-central MT on Tuesday. Westerly
   surface winds of 15-25 mph and minimum RH of 15-20 percent will
   overlap dry fuels, yielding elevated fire-weather conditions.

   Day 3-8 Fire Weather Outlook  
   NWS Storm Prediction Center Norman OK
   0442 PM CDT Sun Sep 27 2026

   Valid 291200Z - 051200Z

   ...Synopsis...
   An embedded short wave within broader westerly flow aloft will
   support a dry, downslope environment over the high plains of MT on
   D3/Tuesday. A closed upper-low will pivot into the Southwest through
   D3/Tuesday while surface high pressure builds into the Intermountain
   West. This will aid in dry, offshore flow across portions of
   southern CA. Ahead of the slow-moving upper low, abundant moisture
   from the remnants of eastern Pacific hurricanes will stream into the
   Southwest and the central/southern Great Plains through midweek
   promoting widespread wetting rains and limited fire weather concerns
   through midweek. Upper level ridging expands across the western U.S.
   in the wake of the exiting closed low bringing warm and dry
   conditions but relatively light winds to the region into the
   weekend, manifesting primarily as a fuels drying event.

   ...Day 3/Tuesday...
   ...North Central Montana...
   Increasing westerly flow aloft over the Northern Rockies and a
   deepening surface low across the Canadian Prairies will support
   enhanced west winds and downslope drying across the high plains of
   MT D3/Tuesday. West winds of 15-25 mph and minimum RH of 15-20% will
   align with dry fuels across portions of north-central MT. 40%
   critical probabilities have largely been maintained. 

   ...Southern California...
   Modest offshore flow is expected to extend into D3/Tuesday across
   southern CA as a closed upper low pivots into the Southwest. A
   northerly wind component up to 20 mph in favored terrain along with
   low RH will support a fire weather concern across portions of
   southern CA where pockets of receptive fuels exist.
