NATIONAL WEATHER SERVICE SALT LAKE CITY UT
921 AM MDT MON MAY 18 2009

.DISCUSSION...A WARM AIRMASS IS IN PLACE ACROSS THE FIRE DISTRICT
TODAY. THIS WILL GENERATE ENOUGH INSTABILITY FOR ISOLATED
THUNDERSTORMS TO FORM THIS AFTERNOON IN THE VICINITY OF THE
PROJECT. THESE WILL BE HIGH BASED AND MOSTLY DRY WITH GUSTY WINDS
AND DRY LIGHTNING POSSIBLE. AN INCREASING SOUTHWEST FLOW WILL
BRING AN INCREASE IN MOISTURE TO THE AREA TUESDAY. THESE
SOUTHWEST WINDS WILL MIX DOWN TO THE PROJECT SITE BY AFTERNOON
BUT THERE WILL ALSO BE A GREATER CHANCE OF SHOWERS AND
THUNDERSTORMS. THESE WILL BE WETTER STORMS THAN TODAY BUT THERE
WILL STILL BE A THREAT OF GUSTY WINDS AND LIGHTNING. A COLD FRONT
WORKING ACROSS NORTHERN UTAH ON WEDNESDAY IS FORECAST TO STALL
NEAR OR JUST NORTH OF THE PROJECT. SHOWERS AND THUNDERSTORMS ARE
EXPECTED TO DEVELOP ALONG THIS BOUNDARY AGAIN WEDNESDAY AFTERNOON
AND EVENING...ONCE AGAIN IMPACTING THE PROJECT SITE. ENOUGH
MOISTURE IS EXPECTED TO REMAIN ACROSS THE AREA THROUGH THE END OF
THE WEEK TO GENERATE SHOWERS AND THUNDERSTORMS EACH DAY.
