Fire Weather Planning Forecast for Southwestern California
National Weather Service Los Angeles/Oxnard CA
859 AM PDT Mon May 21 2018

.DISCUSSION...
A cutoff low pressure system has moved over the area today and has
deepened the marine layer to as high as 5000 feet across LA County
and up to 3000 feet north of Pt Conception. While officially there is
a very small chance of thunderstorms over the mountains and Antelope
Valley today, in reality there is very little moisture and
instability to work with and thunderstorms are very unlikely, less
than 10 percent chance. Little change is expected on Tuesday. Some
warming and drying and marine layer shrinking is expected Wednesday
through Friday, but another low pressure system from the Pacific
will approach California by the end of the week which will temper the
warming and maintain below normal temperatures.
