.DISCUSSION...A SHORT WAVE CURRENTLY OVER THE GREAT SALT LAKE
SPAWNING SHOWERS AND ISOLATED THUNDERSTORMS WILL LIKELY SEND A
BRIEF SURGE OF SOUTHEAST WINDS TO THE FIRE SITE BETWEEN 0500 TO
0800 AS IT PASSES TO THE NORTHEAST...GUSTS UP TO 25 MPH. PASSAGE
OF THIS WAVE SHOULD SUPPRESS SHOWER AND THUNDERSTORM DEVELOPMENT
OVER THE AREA AGAIN UNTIL THIS AFTERNOON. ANOTHER ROUND OF RAIN
AND THUNDERSTORMS IS EXPECTED TO FORM OVER FAR EASTERN NEVADA
THIS AFTERNOON TRACKING FROM SOUTHEAST TO NORTHWEST. A DECENT
SHOT OF WETTING RAINS CAN BE EXPECTED AT TIMES IN THE 1300-2200
