.DISCUSSION...

Hey Nathan,

There is the possibility of some fog forming in low areas tomorrow
morning. Wide spread dense fog is not expected. Winds will be
light overnight and temperatures should rise quickly. Any fog that
does form in low area or drainages will likely evaporate after
10AM as temps start to increase.

We`ll re-run the spot on the overnight shift to give you a more
updated version and writeup with the latest forecast. Please let
us know if you have any additional concerns.
