Discussion
Storms have dissipated for the night, but will be keeping an eye
on a possible boundary moving in from the east along the coast.

Otherwise, clear skies, light winds and slightly lower dewpoints
will make for favorable conditions for patchy fog overnight once
again. Current forecast appears to be on track so no changes are
planned at this time. 41

looks like last of the shra tsra near sgr have dissipated.

Seabreeze continues to push inland and winds becoming south to
southeasterly in the wake of it. ExpectVFR conditions tonight for
most sites though uts cxo cll may briefly go MVFR with CIGS around
1000-1500ft toward sunrise. Otherwise will be watching the
moisture over eastern la NRN gulf spread into the area during the
late morning and especially afternoon and evening. Soundings
showing convective temps around 91-92 degrees with dry subcloud
'high' based storms. May see some gusty winds of 30+ kts during
the mid to late afternoon hours as storms spread west from the
bpt-jas area tapering off early in the evening Sunday. With the
plume of richer moisture over the region Sunday night-tue showers
and thunderstorms impacts may become more common for regional
terminals.

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.
