FIRE WEATHER PLANNING FORECAST FOR NE OREGON AND SE WASHINGTON
NATIONAL WEATHER SERVICE PENDLETON OR
159 PM PDT WED SEP 30 2020
DISCUSSION
A HIGH PRESSURE RIDGE ALOFT WILL REMAIN OVER THE
DISTRICT THROUGH THE END OF THE WEEK INTO SATURDAY. HUMIDITY
RECOVERY AT NIGHT WILL BE MODERATE TO GOOD. IN THE AFTERNOONS,
THEY WILL BE MODERATELY LOW, BUT WINDS WILL BE LIGHT. THE
COMBINATION OF LOW RH AND WIND ARE NOT EXPECTED TO PRODUCE
CRITICAL FIRE WEATHER CONDITIONS DUE TO THE WINDS ONLY BEING
LIGHT. SMOKE FROM WILDFIRES TO THE SOUTH IN CALIFORNIA, AND ALSO
IN THE OREGON CASCADES WILL PRODUCE SMOKE WHICH WILL DEGRADE THE
AIR QUALITY OVER CENTRAL AND NORTH CENTRAL OREGON THROUGH THE END
OF THE WEEK.
***WINDS ARE 20 FOOT 10 MINUTE AVERAGES***
