.DISCUSSION...
Good afternoon Amy,
Tomorrow morning we`ll start off with some patchy fog as RH values
recover to near 100%. Light winds in the morning will gradually
increase in the afternoon to around 5 mph. Although surface winds
will be on the lighter side of ideal, transport winds should
increase to 10+ mph by early afternoon. RH values are expected to
drop into the mid 30s with plenty of sunshine and a high near 90.
Conditions for patchy fog are expected to set up again on Sunday
morning, but widespread dense fog is not expected. Just the
typical low lying areas that could see some reduced visibility
before 10 am.
We`ll have the mid shift re-run this spot for you, but please let
us know if you have any questions for planning purposes.
