.DISCUSSION...
Advancing high pressure is expected to keep largely dry conditions
under sunny skies. Winds will be generally easterly to begin the
day and then will slowly veer to the south and then west. Winds
are expected to be largely on the lighter side owing to high
pressure. A brief period in the mid morning hours may feature
SE`rly winds parallel to the two ridges on either side of Sandy
Creek but wind speeds are expected to be less than 10 mph during
this time frame. Minimum RH is expected to be near 50 percent but
could dip into the upper 40 percents. The inversion looks to break
by noon.
