SYNOP: (NWS SAN DIEGO)
Low inland humidity and gusty southwest to west winds will bring elevated to locally critical fire weather conditions for the mountains and deserts for this afternoon. Saturday through Monday will have weaker winds with high pressure to the south bringing a daytime warming trend. A trough of low pressure passing by to the north will spread cooling and higher coastal humidity inland for Tuesday and Wednesday. For Thursday into Friday, a period of moderate strength offshore flow could bring critical fire weather conditions to the mountains, valleys, and inland Orange County from the combination of stronger and gusty northeast winds and lower inland humidity.

There will be little change in temperature today.

· Temperatures will be near normal, with upper 50s and 60s across the mountains and mid 70s to mid 80s in the valleys.

· West winds of 15 to 25 mph with gusts to 40 mph will surface across the desert passes this morning.

· Temperatures will become a little above normal Saturday through Monday.

· Temperatures will cool Tuesday and Wednesday, with near normal temperatures Wednesday and Thursday.

· West winds of 20 to 30 mph with gusts to 50 mph will surface across the desert passes Tuesday afternoon through Wednesday evening.

· Minimum humidity will be mainly in the single digits and teens away from the coastal areas through Thursday.

· Gusty northeast winds will surface across the mountains and below the canyons and passes of Southern California Thursday.

NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)
Dry and mild conditions are expected through early next week. Some breezy winds are expected across central NV and northwest AZ this afternoon as a trough continues to dig into the region. West to southwest winds expected to remain below 20-25 mph in those regions. Lighter winds expected Saturday. Some breezy north winds are expected early Sunday as a weather system passes to the northeast. Otherwise, the next notable weather impacts are expected middle of next week with another weather system which will bring gusty winds and cooler temperatures.

DAILY FUELS/FIRE POTENTIAL:
Light winds away from the desert passes will keep the large fire threat low across the area through the middle of next week. The large fire threat may increase Thursday depending on the strength of an expected offshore flow event. There will be a significant decrease in fuel moistures and a substantial increase in ERC’s over the next week due to the long period of very low humidity. Expect light initial attack activity to continue through the middle of next week and then possibly an increase in IA activity Thursday.

SANTA ANA WILDFIRE THREAT INDEX: TODAY: GREY-NO RATING
NO RATING: Sundowner winds are either not expected, or will not contribute to significant fire activity.

MARGINAL: Upon ignition, fires may grow rapidly.

MODERATE: Upon ignition, fires will grow rapidly and will be difficult to control.

HIGH: Upon ignition, fires will grow very rapidly, will burn intensely, and will be very difficult to control

EXTREME: Upon ignition, fires will have extreme growth, will burn very intensely, and will be uncontrollable.
