VERY COLD AIR BEHIND THE ARCTIC FRONT IN A NORTHERLY FLOW WILL
SETTLE ACROSS THE PACIFIC NORTHWEST THE FIRST PART OF THE COMING
WEEK. TEMPERATURES WILL BE WELL BELOW NORMAL AND WILL NOT RISE TO
ABOVE FREEZING THROUGH AT LEAST TUESDAY. LATER THIS WEEK THE FLOW
ALOFT WILL BECOME MORE NORTHWEST AND THEN WEST WHICH WILL ALLOW A
SLOW MODERATION OF TEMPERATURES DURING THE LATTER HALF OF THE WEEK.
THERE MAY BE VARIOUS PACIFIC WEATHER SYSTEMS THAT MAY RIDE UP AND
OVER THE DOME OF ARCTIC AIR IN PLACE LATER THIS WEEK AND COULD CAUSE
A WINTRY MIX OF PRECIPITATION TOWARD THE END OF THE WEEK INTO NEXT
WEEKEND. THAT SITUATION WILL BE MONITORED CLOSELY. PLEASE KEEP AWARE
OF THE LATEST FORECASTS AND WARNING AND/OR ADVISORIES WHICH MAY BE
ISSUED AS A RESULT THROUGH THIS NEXT COMING WEEK.
