Aviation
A mix of MVFR andVFR ceilings will persist through the afternoon
hours with ceilings generally ranging from 2500 to 5000 feet.

Winds will be gusty from the south with some gusts to around 20 to
25 knots possible through 00z. After 00z, winds should begin to
die off as daytime heating wanes. This drop off in winds will also
allow for another low level inversion to begin forming, and
expect to see another round of low ceilings and fog take hold
after 08z. Ceilings should drop down to lifr range of 300 to 500
feet by 10z and remain at these levels through around 14 to 15z.

Visibilities should also drop off in response to the lower
ceilings with most areas remaining between 1 and 3 miles. However,
kmcb could once again fall to around 1/2 mile for an hour or two
around 12z. After 15z, enough mixing of the boundary layer should
occur to increase ceilings back into MVFR and fuel alternate range
of around 1500 to 2000 feet. 32

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
