Weather
A return to a cooler and more humid weather pattern is expected as a series of cold core systems make their way into the area.  However, today will be sunny and warm with above normal temperatures.  Highs will reach the mid and upper 80s in the valleys and some mid slope and lower elevations will continue to see afternoon RH readings below 15%.  Winds will be light throughout the day with some afternoon sea breezes of 10-15 mph this afternoon.  This weekend, onshore flow will strengthen, which will bring 3-5 degrees of cooling each day along with a return of the marine layer to coastal areas.  Northerly flow will introduce some mid level moisture into Central California, allowing isolated showers and one or two high elevation thunderstorms to develop in the Sierras Saturday and Sunday.  Rainfall will be under a tenth of an inch.  Monday and Tuesday, a weak low over the area may allow additional showers to develop over the rest of Central California, including the San Joaquin Valley and the central coast region.  Rainfall will continue to be very light.  A deeper trough is expected to arrive during the middle of next week which may bring a bit more moisture into the area.  More widespread rainfall may be possible in Central California next Wednesday and Thursday with isolated showers possible as far south as the Angeles and San Bernardino National Forests.  Some areas of Central California, including the central and southern Sierras may see over a quarter of an inch of rain from these midweek showers.  Temperatures next week look to remain a few degrees below normal with highs in the 50s in the mountains to the lower 70s in the valleys.  Snow levels may fall to under 5,000 feet by next Wednesday or Thursday.  The precipitation should end by next Friday, leaving cool temperatures and strong northwest winds in its wake for the weekend of the 25th

Fuels/Fire Potential

Large fire potential should decrease markedly this weekend as cooler and more humid conditions envelop the area.  It will turn windy in the Antelope Valley and nearby areas of Canyon Country during the afternoon hours this weekend.  While ignition components will be lower this weekend, wind driven fire behavior can be expected with any new start in the desert interface regions.  Next week, large fire potential will be low with cool, cloudy and showery weather.  Some high elevation thunderstorms can be expected in the Sierras this weekend and over much of Central California during the middle of next week.  But all of the thunderstorms should be accompanied by some precipitation.  Look for light IA today through the weekend with little, if any, resource demand next week.
