.DISCUSSION...
A WARM AND MOIST SOUTHERLY FLOW ALOFT WITH A WEAK SURFACE THERMAL
TROUGH OVER THE COLUMBIA BASIN WILL PROMOTE WARM TEMPERATURES...LIGHT
AND MAINLY TERRAIN DRIVEN WINDS...AND A CHANCE OF THUNDERSTORMS OVER
NEARBY PEAKS AND RIDGE LINES TODAY THROUGH MONDAY. THESE STORMS AND
THE WETTING RAIN UNDER THEIR CORES WILL LIKELY REMAIN NEARLY STATIONARY
OVER PEAKS AND RIDGES. THE FIRE AREA WILL LIKELY RECEIVE ONLY SPRINKLES
OR A LIGHT BRIEF SHOWER ON THE EDGE OF THESE STORMS. THE THUNDERSTORM
THREAT WILL PEAK IN THE EARLY EVENING TONIGHT AND ABATE AFTER SUNSET.
ON MONDAY GENERALLY SIMILAR CONDITIONS ARE EXPECTED...BUT WITH A SLIGHTLY
SMALLER RISK OF NEARBY AFTERNOON THUNDERSTORMS.
