.DISCUSSION...

Light but generally southerly winds will persist across the
region through Saturday keeping moisture profiles fairly stable.
Despite dry weather and a breezy southerly wind, relative
humidity levels each day will be well above critical thresholds.
Wetting rainfall is anticipated Sunday.

.REMARKS...
1) This morning does not look to be a super fog event since the mixed
layer is about 3500ft deep this morning. This changes tonight
into Saturday morning as mixing depths lower to about 1100ft and
chances of fog reducing vis to <=1/2 mile is about 40%. These
conditions can cause a super fog event Saturday morning. These
depths are maximum in feet, but these levels and the lowering of
the mixed layer are also shown well in the text below labeled "Mix
hgt (km or m)".
