The weak trough which has brought relatively cool weather to much of the area will depart the region, allowing high pressure to build over the state during the second half of the week.  This will result in drier and warmer weather Wednesday through Friday.  Yesterday, onshore flow produced wind gusts to around 45 mph in the Antelope Valley and Banning Pass, but wind speeds should only reach the 15-25 mph this afternoon.  As high pressure strengthens across the state, expect weaker onshore flow and light winds the rest of the week.  By Thursday and Friday, the interior valleys and lower foothills below 2,000 feet to approach 100 degrees with readings in the upper 70s to mid 80s in the mountains below 7,000 feet. Minimum RH may reach 10-15% for 3-5 hours each afternoon in the midslope regions. Remnant moisture from Hurricane Marie may result in an increase in high clouds which may take the edge off afternoon temperatures Friday. This weekend, another trough over the Great Basin is expected to produce cooler temperatures and stronger onshore flow.  Wind gusts to 45 mph may be possible in and near the deserts during the afternoon hours this weekend.  No thunderstorms are expected during the period

Fuels/Fire Potential

Large fire potential will generally remain low over most of the region this week, mainly due to a lack of lightning.  However, gusty winds would allow for rapid rates of spread on desert-adjacent areas of the Angeles, San Bernardino and Cleveland National Forest again this afternoon.  The rest of the week, sunny and warm weather will result in strong drying conditions in areas which received recent rainfall.  Higher ERC and BI values will return during the afternoon hours later this week which may result in rapid fire spread and good consumption in exposed areas.  This weekend, large fire potential may climb in urban interface regions and in areas near the desert as strong onshore flow brings windy weather during the afternoon hours.  IA will generally be light this week.
