955 AM MDT TUE OCT 19 2010

.DISCUSSION...ENOUGH MOISTURE REMAINS IN PLACE ACROSS SOUTHERN
UTAH TODAY FOR A THREAT OF AFTERNOON SHOWERS AND THE SLIGHT
CHANCE OF A THUNDERSTORM IN THE VICINITY OF THE PROJECT. MIXING
IS FORECAST TO BE POOR TODAY DUE TO LIGHT TRANSPORT WINDS AND
ONLY A WEAKLY UNSTABLE AIRMASS RESULTING IN LOW CLEARING INDICES.

THE CALIFORNIA UPPER LOW WILL START TO MOVE SLOWLY EAST WEDNESDAY
AND THIS WILL SPREAD ADDITIONAL MOISTURE INTO SOUTHERN UTAH
INCREASING THE CHANCE OF SHOWERS AND THUNDERSTORMS ON THE
PROJECT. CLEARING INDICES WILL IMPROVE WEDNESDAY AS TRANSPORT
WINDS INCREASE OUT OF THE EAST AND THE AIRMASS BECOMES
INCREASINGLY UNSTABLE. THIS LOW CROSSES ARIZONA WEDNESDAY NIGHT
AND THURSDAY...AND KEEPS SPREADING MOISTURE INTO SOUTHERN UTAH AS
IT PASSES TO THE SOUTH. ENOUGH MOISTURE IS LEFT IN PLACE FRIDAY
FOR A CONTINUED CHANCE OF SHOWERS AND THUNDERSTORMS ACROSS THE
PROJECT SITE.
