...ELEVATED FIRE WEATHER CONCERNS FROM THUNDERSTORM CHANCES TODAY...
.DISCUSSION...
Scattered showers and thunderstorms are in the forecast across
interior NorCal today. Storms that do develop are expected to be
mostly wet, but lightning strikes outside the main precipitation
core will pose a risk for new fire starts. Gusty erratic outflow
winds from storms that develop will also pose a risk. High
temperatures continue to cool today, but will gradually warm
into the weekend with lowering humidities.
