SPOT FORECAST FOR RIFLE AIR SHOW...NFS
NATIONAL WEATHER SERVICE GRAND JUNCTION CO
614 PM MDT FRI JUL 13 2012

FORECAST IS BASED ON INCIDENT TIME OF 1755 MDT ON JULY 13.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...THE COLLAPSING THUNDERSTORM CELL THAT GENERATED 50
MPH WINDS AT THE AIRFIELD HAS CAUSED SHOWERS AND EMBEDDED
THUNDERSTORMS TO DEVELOP WEST AND NORTHWEST OF THE AIRPORT. AS A
RESULT...EXPECT STRONG SOUTHWEST WINDS TO GRADUALLY SHIFT TO THE
WEST WHILE DECREASING OVER THE NEXT 30 MINUTES. DURING THIS TIME
LIGHT SHOWERS WILL BRIEFLY IMPACT THE AIRPORT BUT SHOULD DISSIPATE
BY OR SHORTLY AFTER 630 PM. ADDITIONAL SHOWERS WERE LOCATED OVER
THE MOUNTAINS SOUTH OF RIFLE AND MAY IMPACT THE AIRSHOW AGAIN
AROUND 7 PM. MUCH OF THIS ACTIVITY WAS MOVING ALONG THE BATTLEMENT
MESA AND AS SUCH SHOULD PASS SOUTH OF THE AIRFIELD. OUTFLOW WINDS
GENERATED WOULD BE CONSIDERABLY LIGHTER THAN EARLIER AS LOWER
ATMOSPHERE NOW MUCH MORE MOIST THAN PRIOR TO THE EARLIER GUST.

.REST OF TONIGHT...

SKY/WEATHER.........MOSTLY CLOUDY (60-70%) THEN BECOMING PARTLY
                    CLOUDY (40-50%) LATER TONIGHT. BRIEF LIGHT
    SHOWERS THROUGH 630 PM WITH POSSIBLE
    REDEVELOPMENT AROUND 7 PM. SHOWERS AND
    THUNDERSTORMS DIMINISHING OVERNIGHT.
MIN TEMPERATURE.....55-60 F.
20-FOOT WINDS.......SOUTHWEST 10 TO 15 MPH WITH GUSTS TO 25 MPH
    GRADUALLY SHIFTING WEST AND DECREASING TO 5 TO
    10 MPH BY AROUND 630 PM. AS ALWAYS...GUSTY AND
    ERRATIC WINDS CAN BE EXPECTED NEAR THUNDERSTORMS.
