Another very warm day is on tap across Southern California today with near record high temperatures expected this afternoon.  Highs will range from the upper 70s and 80s over the mountains of Southern California to the mid 90s at lower elevations.  Minimum RH yesterday was in the teens over most areas yesterday and very similar readings will occur this afternoon.  Across Central California, onshore flow will return to the coastal areas ahead of a trough approaching the Pacific Northwest and temperatures should be a bit cooler north of Pt. Conception.  This weekend, onshore flow will increase which will lead to cooler temperatures.  By Sunday, high temperatures will be in the 80s in the valleys and upper 60s to lower 70s in the mountains.  A very weak area of circulation may allow for some cumulus buildups across the Sierra Crest with one or two showers possible Saturday and Sunday afternoon.  Next week, a warming trend will occur during the first half of the week, but temperatures should not be nearly as hot as the last two days.  A pair of weak troughs well to our north may bring windy conditions to the Sierras, deserts and the Inyo National Forest next Tuesday and Friday.  No rain is expected during the next 7-10 days.

Fuels/Fire Potential

Exceptionally hot weather will result in a few starts again this afternoon.  Ignition components will be very high for this time of year due to strong sunshine and abnormally dry fuels.  ERC's are now at record high readings for this time of year in dead fuels over most areas.  Fine live fuels, such as seasonal grasses, have cured over most lower elevation sites and will be supportive of fires.  Fortunately, winds will be light this afternoon and rates of spread will be moderate, except where slope and fuels are favorable.  This weekend, cooler and more humid weather will result in fewer starts, but it will turn windy in the deserts and desert interface regions during the afternoon hours.  Next week, the highest potential for large fires will be in the deserts and higher elevations of Central California due to gusty winds.  Some light IA will be possible again today, but less resource demand is expected over the weekend.
