.DISCUSSION...
A FEW SHOWERS ARE ALREADY MOVING INTO FAR SOUTHWESTERN SWEETWATER COUNTY
AT 10 AM THIS MORNING AND THE THREAT OF GUSTY SHOWERS OR AN ISOLATED
THUNDERSTORM WILL BE IN THE FIRE AREA FROM 11 AM THROUGH THE EARLY EVENING
HOURS. THE MAIN RISK FROM THESE STORMS WILL BE GUSTY OUTFLOW WINDS OF
40 TO 50 MPH WITH ISOLATED HIGHER GUSTS POSSIBLE. OTHERWISE, IT WILL BE
QUITE WARM AGAIN TODAY AND DRY WITH MIN RH`S UNDER 15 PERCENT THIS
AFTERNOON. THERE IS A SHALLOW COLD FRONT THAT WILL MOVE SOUTHWESTWARD
INTO EASTERN AND CENTRAL SWEETWATER COUNTY LATER TONIGHT WITH A GUSTY
NORTHEAST WIND BUT RIGHT NOW IT APPEARS THIS FRONT WILL STAY JUST EAST
OF THE FIRE AREA. WEDNESDAY LOOKS DRY, HOT WITH EVEN LOWER RH`S ALONG
WITH A GUSTY AFTERNOON WEST TO NORTHWEST WIND.
