FIRE WEATHER PLANNING FORECAST FOR NORTHWEST CALIFORNIA  
NATIONAL WEATHER SERVICE EUREKA CA  
255 AM PDT THU JUL 2 2020  
 
...A VERY DRY AIR MASS AND CRITICALLY POOR RECOVERIES SATURDAY  
AND SUNDAY ALONG THE UPPER SLOPES AND RIDGES OF ZONES 264 AND  
277...  
 
   
DISCUSSION
 
INTERIOR HIGH TEMPERATURES WILL REMAIN IN THE 80S  
TO AROUND 90 ACROSS INTERIOR VALLEYS THIS WEEK. SOME NORTHWEST TO  
WEST BREEZES WILL CONTINUE, UP THE RIVER VALLEYS AND OVER EXPOSED  
RIDGETOPS, BUT SHOULD TREND LIGHTER THROUGH THE END OF THE WEEK  
COMPARED TO WHAT WE SAW EARLIER THIS WEEK. VERY DRY AIR WILL MOVE  
INTO THE SOUTHERN PORTION OF THE AREA ON SATURDAY AND SUNDAY.  
THIS WILL BRING VERY LOW RH VALUES BOTH DURING THE AFTERNOON AND  
AT NIGHT, WITH CRITICALLY POOR RH RECOVERIES EXPECTED ALONG THE  
UPPER SLOPES AND RIDGES.
