...HEAT ADVISORY IN EFFECT UNTIL 11 PM MDT THIS EVENING...

.DISCUSSION...High pressure continues to drive our current weather
pattern with hot temperatures, breezy afternoon winds, and
critically low min RHs. There is a very small chance for an
isolated shower/storm during the afternoon/evening, but is a bit
more likely south of the fire. Overall confidence in any
shower/storm really getting going is low. Think 5 to 10 percent
chance at fire vs 10 to 15 percent chance farther south near ID/UT
state line. Sunday and Monday will be nearly identical forecasts,
but temperatures drop a couple of degrees each afternoon.
