.DISCUSSION...High pressure continues to build in bringing
warming and drying conditions to the site. RH recoveries will be
moderate on the ridges, but are expected to be better in the
valleys. Winds are generally expected to be diurnally driven
becoming northeast overnight and northwest in the afternoon. An
upper low brings a slight chance (15% or less) for dry
thunderstorms Monday and again on Wednesday. The storms may stay
north and east of the area, but there is quite a bit of
uncertainty on the exact location. Even if the storms remain away
from the site there may still be better ventilation.
