.DISCUSSION...
A wind shift has moved through your area which has brought the winds
around to a north, to north northwest direction, and it will settle
into a 10 to 20 mph range until mid afternoon. From about 3 pm
onward, the winds will decrease a bit. This will change on Saturday
however, as northwest winds will be quite strong at about 20 to 30
mph, perhaps with even some gusts upwards of 35 mph. Smoke dispersion
will be fair to good by late morning as the lower atmosphere mixes
out. Minimum humidity values will bottom out in the mid 50s percent.
