NATIONAL WEATHER SERVICE GRAND JUNCTION CO
1039 AM MDT MON AUG 3 2009

FORECAST IS BASED ON REQUEST TIME OF 0950 MDT ON AUGUST 03.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.

.DISCUSSION...THE PATTERN REMAINS THE SAME...WITH A RIDGE OF HIGH
PRESSURE STRETCHED FROM NEW MEXICO TO OREGON. THERE IS SOME MID-
LEVEL MOISTURE THAT MAY PRODUCE SOME AFTERNOON VIRGA AND LOCAL
OUTFLOW WINDS...PERHAPS A THUNDERSTORM OVER THE ABAJO MOUNTAINS.
NOT MUCH CHANGE EXPECTED ON TUESDAY AS THE RIDGE BUILDS OVERHEAD.
THEN SOUTH-SOUTHWEST GRADIENT WINDS INCREASE ON WEDNESDAY...AND
COMBINES WITH INCREASED MOISTURE ON THURSDAY AND FRIDAY AS A
PACIFIC LOW PRESSURE SYSTEM PUSHES TOWARDS THE NORTHERN ROCKIES.

***FEEDBACK NOTE: WHILE MID-MORNING OBS ARE USEFUL TO DETERMINE
 WHEN THE INVERSION IS BREAKING...WE WOULD LIKE TO GET SOME
 FEEDBACK ON HOW THE FORECASTED MAX/MIN T/RH AND WINDS ARE DOING.
