.DISCUSSION...
Moisture begins to decrease today, dropping to near normal levels
through the weekend. Shower and storm chances will continue to be
possible each afternoon, particularly over the higher terrain. On
the other hand, wetting rain chances decrease. Localized heavy
rainfall is possible with these storms, which pose a threat of
flash flooding and debris flows, especially over recent burn
scars. Critical fire weather conditions are not expected through
at least early next week.
