Leon,s Backyard WX Report

Large fire potential will moderate somewhat due to cooler temperatures over the weekend. However, locally breezy conditions in the desert interface regions will allow any new start to grow rapidly and move quickly through dead fuels and cured grasses. During the past 10 days, fires have been showing rapid growth in continuous dead fuels and cured grasses, but less aggressive behavior in live fuels. This may be due to live fuel moisture readings remaining well above critical thresholds at the…

  DAILY FUELS/FIRE POTENTIAL: Large fire potential will be elevated once again across the Kern County Mountains, the north sides of the Angeles and San Bernardino N.F. as well as Canyon Country of northern Los Angeles County. Gusty winds, above normal temperatures and single digit RH will cause rapid fire spread in any new start during the afternoon hours today. After today, large fire potential will be lower across the region due to less windy weather. However, it will turn…

**Cooler weather expected by mid-week***   ***Windy and dry across the deserts during the afternoon and evening hours through Tuesday*** High pressure over the Desert Southwest will weaken as a trough moves across the Pacific Northwest and Northern California during the next few days. While temperatures will start to lower in some areas today, it will still be very hot and dry across many of the inland valleys with afternoon highs near 105. The mountains will see temperatures in the…

DAILY FUELS/FIRE POTENTIAL: Another sunny and very hot day will send ERCs and ignition components to very high levels during the afternoon. Expect moderate to rapid rates of spread during peak heating hours where fuels and terrain are in alignment. The highest potential of large fires today will be in the Sierra Foothills where near record high temperatures and a fuel bed loaded with dead fuels and heavy grass will allow for rapid fire growth. The focus of large fire…

  DAILY FUELS/FIRE POTENTIAL: Large fire potential will continue to be elevated the next few days due to hot and dry conditions. Dead fuel moisture is below normal, except for the highest elevations of the Sierras. Large diameter fuels will now support fire growth during peak heating hours. Expect high energy release components and burning indices the next few days with very rapid rates of spread where fuels and terrain are in alignment. The highest potential for the development of…
