Weather

A weak ridge of high pressure will build over the area today, bringing partly to mostly sunny and warmer weather to the region through Friday.  Temperatures today will climb well into the 80s across the inland valleys with 70s common along the coast and in the mountains below 7,000 feet.  By Thursday and Friday, some inland locations of Southern California will see highs near 90.  Winds will be light over most areas, but northwesterly winds of 15-25 mph with gusts to 35 mph will continue in northern Los Angeles County near the I-5 Corridor.  Minimum RH will fall into the 15-20% range away from the coast for 3-5 hours Thursday and Friday afternoon.  Much cooler weather can be expected for the weekend as a cold storm system passes through the northern part of the state.  Temperatures will fall to below normal readings Saturday and Sunday over most areas.  Widespread rain can be expected over the northern half of the state.  Most of the precipitation will remain to our north, but areas from San Luis Obispo and Fresno County northward may see some precipitation during the day Saturday.  The heaviest rain will likely occur over Monterey County and the Sierras from Yosemite N.P. northward where over a half inch of rain will be possible.  It will turn very windy in and near the deserts during the afternoon hours this weekend.  Next week, high pressure may rebuild over the area, leading to drier and warmer weather.  Weak offshore flow may occur next Monday before another storm impacts the northern part of the state during the middle of next week.

Fuels/Fire Potential

Large fire potential will be low overall during the next few days due to light winds.  However, warmer and drier conditions may allow for a higher number of new starts as burning indices will be quite high across inland areas each afternoon through Friday.  This weekend, the highest likelihood of a large fire may be across the desert interface regions such as the Banning Pass and the eastern Cleveland National Forest where conditions will be quite windy this weekend.  Even though RH will be higher over most areas by Saturday, new starts in these regions may grow quickly due to strong surface winds.  Next week, some light offshore flow may occur Monday, but winds are not expected to be strong enough to raise the Santa Ana Wildfire Threat Index beyond the "no rating" category.  Expect light IA through the period.
