.DISCUSSION...AN AREA OF SHOWERS AND EMBEDDED THUNDERSTORMS WILL
CONTINUE TO PUSH NORTHWARD ACROSS SOUTHWESTERN UTAH THIS
AFTERNOON. THIS AREA OF CONVECTION IS ASSOCIATED WITH A MOISTURE
SURGE MOVING NORTHWARD ACROSS SOUTHERN UTAH THIS AFTERNOON. WITH
A LARGE AREA OF RAIN COOLED TEMPERATURES ACROSS NORTHERN ARIZONA
AND EXTREME SOUTHERN UTAH...A SOUTH TO EAST SOUTHEASTERLY
GRADIENT HAS DEVELOPED AND SHIFTED WINDS TO THIS DIRECTION. THIS
SHOULD KEEP SOUTHEAST TO SOUTH WINDS AT THE FIRE SITE. WINDS MAY
BE ERRATIC AT TIMES NEAR STRONGER SHOWERS AND THUNDERSTORMS.
WHILE SOUTHERLY WINDS ARE EXPECTED TO CONTINUE ACROSS
SOUTHWESTERN UTAH OVERNIGHT...THERE IS A SLIGHT CHANCE CONDITIONS
WILL STABILIZE ENOUGH TO SHIFT WINDS TO A MORE
DOWNSLOPE/DOWNVALLEY COMPONENT.

HUMIDITIES WILL RAPIDLY DECREASE TOMORROW AFTERNOON AS A PACIFIC
TROUGH APPROACHES THE REGION. WINDS WILL ALSO BE QUITE STRONG
DURING THE AFTERNOON AND EVENING. THIS WILL BRING NEAR RED FLAG
CONDITIONS TO THE BURN SITE...ALTHOUGH A RED FLAG WARNING HAS NOT
BEEN ISSUED FOR THE FIRE LOCATION ITSELF DUE TO FUEL STATUS.
