==============================================================================
SOUTH OPS WX:
High pressure and very light northeast gradients will maintain mostly sunny, warm and dry weather through the weekend. Low level winds will turn northerly Saturday night which will lead to some gusty winds along the I-5 Corridor which will last through Monday. A weak trough will produce cooler temperatures with strong north winds in the desert and Owens Valley Sunday night into Monday. Offshore winds will likely develop across Southern CA late Monday night which will continue into midweek.

ꞏ High temperatures through Saturday ranging from the 50s in the mountains to the mid 70s across lower elevations. Temperatures will drop 5-8 degrees Monday before warming back up by next Wednesday.

ꞏ Minimum RH will continue to be in the teens across the Sierras and in the 20% elsewhere away from the coast. Looking ahead to next week…there may be some areas of Southern CA which experience RH approaching the single digits by next Tuesday afternoon.

ꞏ North winds of 20-30 mph across the I-5 Corridor Saturday night into Sunday. Monday, expect widespread north winds of 20-30 mph with gusts to 50 mph across the desert, especially the Colorado River Valley and the Owens Valley.

ꞏ Northeasterly offshore winds will likely develop Monday night, which may last through next Wednesday. At this time, wind speeds look to be moderate with some gusts in the 40-50 mph range possible.

ꞏ Light showers (precipitation < 0.10”) possible in the Sierras north of Fresno County Sunday. Some long-range models show additional rainfall chances the weekend of the 22nd, but rainfall amounts do not appear substantial at this time. SYNOP: (NWS SAN DIEGO) Weak onshore flow will prevail through the weekend. Gusty offshore winds are expected to develop as early as Monday, with offshore flow likely continuing through at least Wednesday. There is potential for these winds to be strong and damaging, especially on Wednesday. However, there remains some uncertainty regarding timing and exact strength. NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY) Dry and tranquil conditions are expected through Sunday with generally light winds and above normal temperatures. A weak weather system will bring increasing winds to the region Monday into the middle of next week, along with cooler temperatures. DAILY FUELS/FIRE POTENTIAL: Large fire potential will remain low through the weekend. However, the specter of offshore winds returning next week may lead to some IA across Southern CA due to deteriorating fuel moisture conditions. Dead fuel moisture is plummeting and is well below normal across areas of Southern CA below 6,000 feet. Fuel beds dominated by dead fuels – even those of larger diameter – may carry fire during windy periods next Monday night through Wednesday. Live fuel moisture may limit spread across many areas, but areas with a lot of old growth or dead fuels may see some large fire potential for the first time in months. Winds will be light by the end of next week, but a lack of recent rainfall may be a harbinger of an early start to “spring grass fire season.” SANTA ANA WILDFIRE THREAT INDEX: TODAY: GREY-NO RATING -------------------------------------------------------------------------------------- APPLE VALLEY / HESPERIA-VICTOR VALLEY (CAZ260): .TODAY...
