AFTER LINGERING MOISTURE
BROUGHT DAILY SHOWERS AND THUNDERSTORMS FOR THE PAST WEEK, WE
BEGIN AN AGGRESSIVE DRYING TREND ON THE PERIPHERY OF AN APPROACHING
TROUGH. DEWPOINTS THIS AFTERNOON ARE FORECAST TO FALL 10-20
DEGREES FROM YESTERDAY, AND PW RETURNS TO NEAR/BELOW-NORMAL FOR

OF TERRAIN FEATURES THROUGH THE WEEKEND. ALSO EXPECT SOME
SLIGHTLY COOLER TEMPERATURES, BUT NOT A SUBSTANTIAL COOLING TREND.
DAYTIME TEMPERATURES THIS WEEKEND WILL LAND RIGHT AROUND NORMAL
FOR THIS TIME OF YEAR.
MONDAY AND ONWARD...RIDGING BEGINS TO BUILD FROM THE SOUTH FOLLOWING
THE TROUGHS DEPARTURE. EXPECT A SLIGHT WARMING TREND TO BEGIN NEXT
WEEK. THE SETUP MAY ALLOW FOR MOISTURE TO NUDGE BACK INTO THE

GUIDANCE THAT ABOVE NORMAL PW WILL RETURN BY THE MIDDLE OF NEXT
WEEK. THE CURRENT FORECAST MAINTAINS A SLIGHT CHANCE OF DAILY
