BUSY NIGHT. FLASH FLOOD WATCH AND WIND ADVISORY ARE WORKING OUT WELL.
CPL OF FLASH FLOOD WARNINGS NOW IN EFFECT...AND KMRX 88D SHOWING 40-45
KT WINDS AT MT ELEVATIONS. VALLEY LOW TEMPS A BIT TRICKY. DEWPTS IN
THE LOWER 40S ATTM. W/STRONG SRLY FLOW AND WIDESPREAD RAIN DON'T
EXPECT MUCH MORE OF A FALL. WOULD PREFER UPPER 30S TRI AREA TO LOWER
40S CHA. FROPA WL PASS CSV BEFORE 12Z. HOWEVER MID 20S SOUNDS TOO LOW
THERE AS WELL. WOULD PREFER AROUND 30. WINDS TAKING FOREVER TO MIX
DOWN HERE IN THE VALLEY. BELIEVE WINDS WL REACH THEIR FCSTD SPEEDS SO
ONLY CHG WOULD BE TO ADD "BECOMING".
