.DISCUSSION...
Somewhat cooler temperatures and higher humidity levels will affect the
wildfire site today. The greatest concern today is increasing south to
southwest winds where gusts 25 to 30 mph may be common late morning
through the afternoon. Better chances of rainfall may remain just east of
the incident with only modest chances of wetting rainfall. The best
opportunity for rain will occur this evening and overnight. Good overnight
recovery will be followed by slightly drier conditions Tuesday. Although
temperatures will be much cooler through the middle of the week, a dry
airmass will sweep back across the wildfire site allowing minimum
humidity levels to fall back into the teens.


...Thunderstorms imply gusty winds...
