.DISCUSSION...

Good morning Nate,

I re-ran the winds this morning to see if I could squeeze any more
north out of them; but as the high pressure tracks off to our east
we only seem to settle more into easterly winds. The best you`ll
see today is probably 060 around 5-10 mph with gusts as high as 15
mph.

Chance for patchy fog in low lying areas is still there tomorrow
morning as winds turn light and variable overnight with RH
recoveries around 95%.

I`m in the office all day today, so feel free to give us a call if
you have any questions.
