DISCUSSION
HIGH PRESSURE BRINGS CONTINUED DRY CONDITIONS TODAY. THE PREVAILING
BACKGROUND FLOW WILL REMAIN OUT OF THE NORTHWEST THROUGH LATE AFTERNOON,
WHEN IT WILL BEGIN TO BECOME VARIABLE. HOWEVER, THE FLOW MAY BE LIGHT
ENOUGH THAT LOCALIZED TERRAIN/UPSLOPE FLOWS DOMINATE WITH DAYTIME
HEATING. MINIMUM RH VALUES WILL MOST LIKELY BE IN THE UPPER 30S, BUT
COULD DROP AS LOW AS THE LOWER 30S.
THE NEXT POTENTIAL FOR ANY RAIN WILL COME WEDNESDAY AFTERNOON AND
EVENING, ALTHOUGH COVERAGE OF ANY SHOWERS OR THUNDERSTORMS WILL
REMAIN ISOLATED.
