.SYNOPSIS...A COLD UPPER LOW WILL LINGER OVER THE WEST INTO THIS
WEEKEND.

.DISCUSSION...BAROCLINIC BAND HAS HELD TOGETHER NICELY AS IT DRIFTED
SOUTHWARD TODAY AND HAVE EXTENDED SNOW ADVISORIES THRU TONIGHT FOR
UNDER THIS BAND. IT SHOULD DISSIPATE LATER TONIGHT AS THE JET
SUPPORT WANES AND FRONT CONTINUES ON SOUTH. COLD AIR INSTABILITY
SHOWERS WILL BE THE RULE FOR THE NORTH TONIGHT...AND EACH DAY THRU
FRIDAY. THESE WILL BE MOST ACTIVE IN THE AFTERNOONS AND EVENINGS
BUT SOME WEAK UPPER SUPPORT MAY KEEP A FEW GOING OVERNIGHT AND INTO
THE MORNINGS. COLD AIR ALOFT NEVER REALLY GETS INTO THE SOUTH SO
THEY WILL REMAIN ON THE DRY SIDE AFTER TONIGHT. WINDS SUFFICIENT
THRU THIS EVE TO KEEP AN ADVISORY GOING FOR THE SOUTHEAST PORTIONS
BUT THEY DECREASE ONCE THE FRONT PASSES...AND WILL DECOUPLE SOMEWHAT
LATE THIS EVENING...EVEN AHEAD OF THE FRONT.

LOW FINALLY MOVES OUT ON SUN WITH ANOTHER WEAKER TROF SLIDING PAST
IN THE NORTHWEST FLOW EARLY NEXT WEEK.
