.DISCUSSION...HIGH PRESSURE OVER THE AREA TODAY WILL SHIFT EAST
TOMORROW AS A SERIES OF WEAK SYSTEMS BEGIN TO MOVE THROUGH THE
NORTHERN INTERMOUNTAIN REGION. MOSTLY CLEAR SKIES AND DIURNALLY
DRIVEN WINDS CAN BE EXPECTED AGAIN TONIGHT. A WEAK COLD FRONT WILL
MOVE INTO NORTHERN UTAH ON WEDNESDAY.  AHEAD OF THIS
BOUNDARY...ANTICIPATE THAT SOUTHWEST WINDS WILL INCREASE A BIT OVER
THE BURN AREA ON WEDNESDAY. THERE WILL ALSO BE A SLIGHT CHANCE OF
THUNDERSTORMS OVER THE HIGH TERRAIN AS THE AIRMASS BECOMES A BIT
MORE UNSTABLE AHEAD OF THE FRONT. THIS THREAT FOR ISOLATED STORMS
OVER THE HIGHER TERRAIN WILL CONTINUE THROUGH THE END OF THE WEEK.
BELIEVE THAT WINDS WILL BACK DOWN A BIT ON THURSDAY AS THE WEAK
SYSTEM IN THE NORTHERN INTERMOUNTAIN REGION MOVES EAST. FOR FRIDAY
WINDS MAY INCREASE ONCE AGAIN AS ANOTHER WEAK FRONT APPROACHES
NORTHERN UTAH.  ALSO ANTICIPATE A BIT OF AN UPWARD TREND IN THE
MINIMUM RELATIVE HUMIDITY VALUES TOWARD THE END OF THE WEEK.
