THE FIRE WEATHER WATCH IN EFFECT

HIGH PRESSURE WILL CONTINUE OVER THE NORTHERN ROCKIES ON FRIDAY
MORNING, THEN THE RIDGE FLATTENS IN THE AFTERNOON. THE RIDGE
BREAKDOWN WILL BRING CONTINUED DRY CONDITIONS WITH INCREASED WEST
WINDS. EXPECT GUSTS TO REACH 25 MPH IN THE AFTERNOON, WITH ABOUT A
30% CHANCE OF REACHING 30 MPH, ALONG WITH HUMIDITY IN THE LOW
