.DISCUSSION...

Warm evening temperatures and elevated onshore winds will maintain
near critical fire weather conditions into the late evening hours.
Winds will continue to be elevated through the forecast period but
onshore flow will lead to cooler temperatures and higher humidity
beginning on Wednesday and this will ease fire weather conditions.
A deepening marine layer by late Wednesday and into Thursday will
likely bring low clouds and fog to the forecast site further
increasing the humidity and cooling the temperature.
