Weather
Weaker onshore pressure gradients and a shallower marine layer will allow for quicker clearing along the coast and valleys today.  High temperatures will be 3-5 degrees warmer over most locations with valley high temperatures close to 80 degrees.  Mountain locations will be in the 60s.  Yesterday, only a handful of thunderstorms were seen in the high Sierra with around 30 lightning discharges near the Crest.  Expect similar numbers today and Thursday.  Winds in the deserts should be weaker than the past few days, but the Antelope Valley and Banning Pass may still see some gusts to 25 mph this afternoon.  Thursday and Friday, high pressure will build over the region, resulting in significantly warmer temperatures.  The valleys will be in the lower 90s by Friday with 100-105 readings returning to the low deserts.  Winds will be light. No thunderstorms are expected this weekend.  Afternoon RH will fall into the teens from 1,000 – 6,000 feet for 6-8 hours each afternoon Thursday through Saturday, but RH recovery should be good each night.  Cooler, onshore flow will return Sunday through the first half of next week.  Long range models indicate a change to a hotter and drier pattern may be ensuing during the second week of June.

Fuels/Fire Potential

Large fire potential will continue to be low during the period.  Live fuel moisture outside of the grasses is above normal for this time of year due to the recent rain and the cool weather.  However, dead fuel moisture will drop quickly Friday and Saturday as the weather turns warmer and drier.  ERC's will be higher toward the end of the week and higher afternoon IC values may result in a higher number of new starts in fuel beds dominated by dead fuels.  Winds will be light which will keep rates of spread low.  Expect light IA through the period.
