.DISCUSSION...
UPPER LEVEL RIDGING WILL BUILD OVER THE FIRE FOR THE NEXT COUPLE
DAYS. THE BUILDING UPPER LEVEL RIDGE WILL GRADUALLY STRENGTHEN THE
LOW-LEVEL THERMAL RIDGE. FOR TODAY...THE THERMAL RIDGE WILL AMPLIFY OFF
THE COAST...WHICH WILL WEAKEN THE CROSS-CASCADE PRESSURE GRADIENTS. THIS
WILL RESULT IN LIGHT TERRAIN DRIVEN WINDS. THE THERMAL RIDGE WILL NUDGE
CLOSER TO THE CREST ON SATURDAY...BUT WINDS WILL REMAIN FAIRLY LIGHT. BY
SUNDAY...THE RIDGE WILL FINALLY SHIFT EAST OF THE CASCADES...RESULTING IN
HOT AND DRY WEATHER WITH UNSTABLE LAPSE RATES AND INCREASING WINDS.
