.DISCUSSION...A WEAK WEATHER DISTURBANCE MOVING ACROSS NORTHERN
UTAH TODAY WILL RESULT IN INCREASING MOISTURE AND SOUTHWEST WINDS
OVER THE BURN SITE TODAY. BECAUSE OF THIS...A FEW HIGH BASED
THUNDERSTORMS ARE EXPECTED TO DEVELOP IN THE VICINITY OF THE BURN
SITE DURING THE AFTERNOON HOURS. BY TOMORROW MORNING...THE
DISTURBANCE WILL HAVE EXITED THE REGION...ALLOWING HIGH PRESSURE
TO REDEVELOP. AS A RESULT...WINDS WILL DECREASE AND BECOME
GENERALLY LIGHT AND TERRAIN DRIVEN. HOWEVER...THE AIRMASS WILL
REMAIN SOMEWHAT MOIST...ALLOWING FOR ISOLATED SHOWERS AND
THUNDERSTORMS TO DEVELOP DURING THE AFTERNOON HOURS ONCE AGAIN.
DRIER AIR WILL MOVE OVER THE SITE THURSDAY AS THE RIDGE AXIS MOVES
OVERHEAD. SOUTHWEST FLOW WILL RESULT IN FURTHER DRYING FRIDAY
THROUGH THE WEEKEND.
