OVERCAST WITH LIGHT RAINFALL FROM LAURA….
Today we observed overcast skies with a maximum
visibility of 10 miles at the 1 P.M. observation.
This morning, we had a visibility of a 1/2 mile,
but the fog has let up a little since then. We
had rainfall after 10 A.M., amounting to 0.06
inches by 1 P.M. Wind was 20 mph on average from
the southwest. On radar, it seemed much of the
remnants from tropical system Laura missed us to
the north and south.

the daily normal maximum of 77F. The low since midnight
is 65F, 5 degrees above the average of 60F.
