.DISCUSSION...AN UPPER LEVEL LOW WILL CONTINUE TO MOVE ACROSS
NORTHERN UTAH THROUGH LATE SATURDAY. MOISTURE AND LIFT WILL INCREASE
ACROSS NORTHERN UTAH TONIGHT AS THE LOW APPROACHES. THIS WILL RESULT
IN SHOWERS/THUNDERSTORMS DEVELOPING OVER AND NEAR THE BURN SITE
THROUGH SATURDAY. NORTHERLY WINDS WILL PREVAIL THROUGH TOMORROW
EVENING...HOWEVER THERE IS A SLIGHT CHANCE THAT LIGHT SOUTHERLY
WINDS COULD DEVELOP LATE TONIGHT. AS THE LOW PULLS AWAY ON
SUNDAY...EXPECT A DRIER AND STABLE AIRMASS TO SPREAD INTO THE AREA
WITH LIGHT TERRAIN-DRIVEN WINDS.

FOR THE WHITE ROCKS FIRE...EXPECT OVERNIGHT LOW TEMPERATURES TO BE A
FEW DEGREES COOLER THAN THE BIG POLE FIRE...WITH SLIGHTLY WARMER
DAYTIME HIGH TEMPERATURES. HUMIDITIES WILL BE A BIT LOWER AT WHITE
ROCKS AS WELL. WINDS WILL ALSO BE NORTHWESTERLY WITH SLIGHTLY
STRONGER SPEEDS.
