429 AM MDT TUE AUG 21 2012

.DISCUSSION...DRY MOST DAY TODAY WITH STORMS AND GUSTY OUTFLOW
WINDS EXPECTED TO HOLD OFF UNTIL LATER THIS EVENING INTO THE
OVERNIGHT HOURS. THIS SAID...PRECEDING THE MOISTURE SURGE AND
COINCIDENT RISE OF HUMIDITY TONIGHT THE RED LEDGES FIRE SITE CAN
EXPECT ANOTHER DAY OF DRY CONDITIONS WITH INCREASING
SOUTHWESTERLY WINDS THIS AFTERNOON. HUMIDITY TODAY LOOKS TO
BOTTOM OUT IN THE UPPER TEENS WITH MORNING DRAINAGE FLOW BECOMING
BREEZY SOUTHWEST BY 13-1400. GUSTS TO 25 MPH LOOK LIKELY DURING
PEAK HEATING HOURS WHEN HUMIDITY WILL BE THE LOWEST AS WELL.

REGARDING THE INCREASE OF MOISTURE TONIGHT...SURGE WILL BE COMING
IN FROM THE WEST AFTER 1800 AND WILL PRIMARILY BE AT THE MID
LEVELS. WITH THIS...TIMING SHOULD LIMIT SHOWER/STORM POTENTIAL TO
ISOLATED FOR THE OVERNIGHT HOURS...WITH LITTLE CHANCE OF WETTING
RAINS BUT A HIGHER LIKELIHOOD OF BRIEF GUSTY OUTFLOW. OUTSIDE OF
THE OUTFLOW WINDS WILL BE TRANSITIONING TO LIGHT DRAINAGE BY
22/2300.

MOISTURE WILL CONTINUE TO INCREASE LATE TONIGHT THROUGH TUESDAY
AS A DISTURBANCE APPROACHES FROM THE WEST. WITH THIS LOOK FOR A
HIGHER LIKELIHOOD OF WETTING RAIN POTENTIAL TUESDAY INTO THE
OVERNIGHT HOURS. MOIST CONDITIONS WITH HIGHER HUMIDITY AND A
CHANCE OF WETTING RAINS LOOKS TO CONTINUE THEREAFTER THROUGH
THURSDAY.
