Discussion
Beautiful weather is expected through the next couple of days in
the wake of last night's cold front. Overcast skies have finally
pushed off to the east this afternoon, leaving behind sunny and
dry conditions across the area. High temperatures will gradually
increase from near 70 today to the low to mid 80s by Tuesday under
mostly sunny skies. Clouds and moisture will finally return on
Wednesday as winds become onshore for a period before the arrival
of the next cold front Wednesday afternoon. Some showers and a few
thunderstorms may be possible with this front Wednesday into
Wednesday night. This cold front doesn't appear to be very strong-
only knocking high temperatures back down into the mid to upper
70s.

Models really begin to diverge heading into the second half of
the week. The GFS remains dry with high pressure settling into the
area in the wake of Wednesday's cold front, while the ECMWF has
been trying to bring another shortwave through with some
precipitation on Friday. While this latest ECMWF run is a bit
drier than previous runs, the current forecast will maintain a 20
pop on Friday to account for the uncertainty.

A moderate offshore flow will weaken this evening but will carry the scec
for the offshore waters through 03z to cover slightly higher wind speeds
this evening. A light offshore flow will prevail mon-tues as high pressure
settles over the southern plains. The sfc high will move east and a light
onshore flow will develop tues night into Wednesday. Another weak cold
front will cross the coastal waters Wednesday night with a weak offshore flow
redeveloping weds night and continue into Thursday. Models continue to
lack much run to run continuity and consistency toward the end of the
week. A weak wind regime looks likely toward the end of the week and
wind direction at this time looks like a pick 'em. 43

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.
