.DISCUSSION...
Atmospheric moisture begins to decrease today, dropping to near
or just above normal levels through the weekend. Showers and
thunderstorms will continue to be possible daily, particularly
over the high terrain, but wetting rain chances decrease. Today
localized heavy rainfall is still possible, which may 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.
