 SYNOP:An approaching Pacific trough will bring much cooler temperatures to the region through Thursday. Maximum temperatures will be in the mid 50s to mid 60s across the mountains and 70s to low 80s in the valleys today, with mid 30s to mid 40s across the mountains and upper 50s and 60s in the valleys Thursday.  This trough will also bring showers with up to an inch of rainfall over the Sierra tonight.  The snow level will be around 6,000 feet.  Westerly winds of 20 to 40 mph with gusts to 60 mph will surface across the mountain ridges and desert passes this afternoon through Thursday afternoon.  On the back side of this trough, there will be northerly winds of 20 to 40 mph with gusts to 60 mph across much of Santa Barbara County, the Grapevine, and the Owens Valley Thursday night.  Significant warming along with minimum humidity in the single digits and teens will occur Friday and Saturday as a ridge of high pressure builds into California from the Pacific Ocean.  Local northeast winds of 10 to 20 mph with gusts to 35 mph will surface over the mountains and below the canyons and passes of Southern California Friday morning through Saturday morning.  Another Pacific trough will approach the West Coast Sunday and move inland Monday causing a big cool down and increase in humidity.  Scattered showers with light rainfall totals will move across most of the region Sunday night through Monday evening.  There will be strong westerly winds over the mountains and deserts Sunday afternoon through Monday evening.  A little warming will take place Tuesday and Wednesday as a weak ridge builds into California.   NWS LAS VEGAS – (NORTH & EAST OF BARSTOW TO STATE LINE)

FORECAST DETAILS

significant snow amounts expected.

Visibilities

 

Fire danger will remain elevated for Mohave County & most of the Colorado River Valley through FRI. Fire Potential Discussion: There will be an elevated threat for large fire over the Owens Valley and some other desert/urban interface areas through Thursday due to very strong winds along with humidity in the teens. Rapid rates of spread and long range spotting will be likely on any new ignition in a windy desert area.  Elsewhere, the large fire threat will be low through Thursday as winds will be accompanied by cool temperatures and high humidity.  The potential for large fire will increase a little across Southern California Friday and Saturday as a weak Santa Ana event combines with warm temperatures and very low humidity.  Even though a large fire will be possible across Southern California Friday and Saturday, one will be unlikely since green-up of the annual grasses is prevalent and the live fuel moisture is high.  Strong westerly winds along with low humidity will cause the large fire threat to be focused across the desert/urban interface areas once again Sunday and Monday.  Light initial attack activity will be possible across the region through the forecast period.    

SPECIAL NOTES: NO NEW UPDATES AT THIS TIME
