FORECAST IS BASED ON REQUEST TIME OF 0857 MST ON JULY 18.
IF CONDITIONS BECOME UNREPRESENTATIVE, CONTACT THE NATIONAL WEATHER

.DISCUSSION...TODAY IS EXPECTED TO BE SIMILAR TO YESTERDAY OVER
THE FIRE SITE...AS THE REMAINDER OF THE MORNING IS EXPECTED TO
REMAIN QUIET BEFORE SHOWER AND THUNDERSTORM ACTIVITY RETURNS FOR
THE AFTERNOON AND EVENING HOURS. THE BEST CHANCE FOR SHOWERS AND
THUNDERSTORMS WILL START BETWEEN 1400 AND 1600 MST THIS AFTERNOON
AND WILL CONTINUE THROUGH THE EVENING. OBSERVERS IN THE FIELD
SHOULD BE MINDFUL OF SKY CONDITIONS...AS THE APPEARANCE OF TOWERING
CUMULUS CLOUDS WILL BE AN EARLY INDICATOR OF THUNDERSTORM
DEVELOPMENT. THE MAIN THREAT FROM ANY STORMS THAT DEVELOP WILL BE
VERY STRONG...GUSTY...ERRATIC WINDS...ALTHOUGH THE POTENTIAL FOR
PERIODS OF BRIEF HEAVY RAIN AND DANGEROUS CLOUD TO GROUND
LIGHTNING EXIST AS WELL.
