FREEZING FOG WILL PERSIST AGAIN THIS MORNING ACROSS THE AREAS LISTED
ABOVE. THERE WILL BE LOCAL DENSE FREEZING FOG WITH VISIBILITIES LESS
THAN A QUARTER MILE AT TIMES IN THESE AREAS AS WELL. FOG DROPLETS
WILL FREEZE ON ROADWAYS AND OTHER SURFACES CREATING SLICK
CONDITIONS. A FREEZING FOG ADVISORY IS IN EFFECT UNTIL 11 AM THIS
MORNING FOR THESE LOCATIONS. PLEASE REFER TO NWS HAZARD PRODUCT ID
PDXNPWPDT FOR MORE DETAILS.
HIGH PRESSURE ALOFT WILL CONTINUE TO PRODUCE LIGHT SURFACE WINDS AND
STRONG LOW LEVEL TEMPERATURE INVERSIONS THROUGH TONIGHT. THIS WILL
RESULT IN CONTINUED POOR MIXING AND STAGNANT AIR CONDITIONS. AN AIR
STAGNATION ADVISORY REMAINS IN EFFECT THROUGH AT LEAST TUESDAY
MORNING FOR MUCH OF THE FORECAST AREA. PLEASE REFER TO NWS HAZARD
PRODUCT ID PDXNPWPDT FOR MORE DETAILS. FAIR CONDITIONS WILL CONTINUE
IN THE MOUNTAINS ABOVE THE LOW LEVEL TEMPERATURE INVERSIONS.
.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY
THE PROBABILITY FOR WIDESPREAD HAZARDOUS WEATHER IS LOW.
THE AIR STAGNATION ADVISORY WILL CONTINUE THROUGH AT LEAST TUESDAY
MORNING AND MAY BE EXTENDED BEYOND TUESDAY MORNING IF THE STAGNANT
CONDITIONS DO NOT IMPROVE MUCH OR AT ALL. A WEAKENING PACIFIC WEATHER
SYSTEM WILL MOVE INTO THE REGION AND MAY HELP TO MIX OUT THE TRAPPED
POLLUTANTS UNDER THE LOW LEVEL TEMPERATURE INVERSIONS AS THE PACIFIC
WEATHER SYSTEM WEAKENS THESE INVERSIONS. HOWEVER...IT IS UNLIKELY
THAT THE STAGNANT AIR WILL COMPLETELY MIX OUT SINCE THIS WILL BE A
WEAK WEATHER SYSTEM WITH VERY LITTLE WIND EXPECTED TO BE WITH IT. IN
ADDITION THERE MAY BE AREAS OF FREEZING FOG AND/OR LOW CLOUDS AGAIN
DURING THE LATE NIGHT AND MORNING HOURS EACH DAY THIS WEEK WITH
POSSIBLE ADDITIONAL FREEZING FOG ADVISORIES ISSUED.
PERIODS OF VERY LIGHT RAIN OR SNOW MAY OCCUR ALONG THE CASCADE EAST
SLOPES AND IN THE NORTHEAST MOUNTAINS AS THE WEATHER SYSTEM CROSSES
THE REGION TUESDAY AND WEDNESDAY...AND THEN ANOTHER WEATHER SYSTEM
POSSIBLY BY NEXT WEEKEND.
.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION IS NOT ANTICIPATED AT THIS TIME.
WEATHER SPOTTERS ARE ENCOURAGED TO REPORT SIGNIFICANT WEATHER
CONDITIONS ACCORDING TO STANDARD OPERATING PROCEDURES.
