.DISCUSSION...

AN UPPER LEVEL LOW PRESSURE SYSTEM WILL MOVE SLOWLY SOUTHEAST OUT
OF IDAHO TODAY. THIS DISTURBANCE WILL BRING A SLIGHT CHANCE OF
SHOWERS AND POSSIBLE THUNDERSTORM TODAY THROUGH TUESDAY TO THE
FIRE SITE. THE UPPER LOW WILL SPREAD INCREASING CLOUD COVER OVER
THE AREA ALONG WITH AN INCREASE IN LOW LEVEL MOISTURE. MINIMUM
RH'S ARE ONLY EXPECTED TO FALL INTO THE MID TO UPPER 30 PERCENT
RANGE TODAY AND TUESDAY WITH GOOD RECOVERIES TONIGHT. AREA TERRAIN
WILL CONTINUE TO BRING LIGHT UPSLOPE/VALLEY WINDS DURING THE DAY
WITH DOWNSLOPE/VALLEY WINDS OVERNIGHT. ANY THUNDERSTORMS THAT DO
DEVELOP WILL HAVE THE POTENTIAL TO PRODUCE GUSTY WINDS.
