THE RULE AS THE COLD FRONT PASSES BY THIS AFTN. SNOW LEVELS WILL
GRADUALLY RISE TO 5000-5500 FEET ACROSS EASTERN OREGON BY THIS
AFTN...SO SNOW ACCUMS WILL REMAIN UNDER ADVISORY CRITERIA. THIS

REACH THEIR MAXIMUM THIS MORNING...AS DOES THE MID LEVEL JET
(50-60 KT). WILL HAVE TO MONITOR CLOSELY FOR PSBL WARNING LEVEL
WINDS ACROSS THE BASIN/FOOTHILLS...BUT WITH THE BEST SETUP OCCURRING
