SPOT FORECAST FOR BOX CREEK ASPEN REG
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
924 AM MDT MON SEP 5 2011

.DISCUSSION...QUICK OVERVIEW...MID LEVEL MOISTURE WILL CONTINUE TO
INCREASE FROM THE SOUTH TODAY...WITH SHOWERS AND THUNDERSTORMS
ANTICIPATED TO BUILD THROUGH THE AFTERNOON HOURS. A DISTURBANCE
WILL TRACK IN FROM THE WEST LATE TONIGHT AND TUESDAY THAT WILL
SHIFT MOISTURE A BIT TO THE EAST OF THE BOX CREEK SITE...BUT
ISOLATED THUNDERSTORMS REMAIN A POSSIBILITY TOMORROW AFTERNOON.
MIDWEEK LOOKS DRY WITH MOISTURE RETURNING LATE WEEK.

TRENDS...WITH INCREASED MOISTURE HUMIDITY WILL BE RUNNING HIGHER
AT THE SITE TODAY WITH GOOD RECOVERY TONIGHT. A SLIGHT DECREASING
HUMIDITY TREND IS EXPECTED THROUGH MIDWEEK BUT NOT SUBSTANTIAL.
WINDS WILL GENERALLY REMAIN ON THE LIGHT SIDE WITH NORMAL DIURNAL
FLUCTUATIONS...IE NNE IN THE 3-7 MPH RANGE AT NIGHT AND SW
PHASING WEST DURING THE DAYTIME HOURS. THE ONE HITCH TO THE ABOVE
MENTIONED WINDS IS THAT TODAY SOUTHWESTERLY FLOW ALOFT HAS
INCREASED AND AFTERNOON WINDS MAY TEND TO STAY MORE SOUTHWEST
THAN WEST. CLEARING INDICES WILL RUN EXCELLENT TODAY BUT INCREASED
STABILITY WILL KNOCK THEM DOWN TOMORROW. THAT SAID FEEL THERE
WILL BE ENOUGH TRANSPORT WINDS TO KEEP THEM ABOVE 500. CI TRENDS
LOOK TO GRADUALLY IMPROVE MIDWEEK BUT NOT BY MUCH.
