Discussion
The weather is expected to remain pleasant through the weekend. A
high pressure system is still over our area, which will cause
subsidence and stable conditions through Sunday due to the upper
level convergence and mostly northerly winds present.

The winds will shift to be predominantly southerly by Sunday
morning. This wind shift will allow for some moisture and warm air
advection into the area Sunday night into Monday morning. There is
expected to be upper level divergence Monday morning into Monday
evening, which will help to promote the amount of lift in the
atmosphere. The winds at the middle levels are expected to be
predominantly westerly. A low pressure frontal system is expected
to move through the area Monday night into Tuesday morning. The
middle level winds will shift to be northwesterly Monday morning
into Tuesday evening, which will help enhance the lapse rates.

This could cause a chance of thunderstorms to develop within the
frontal system. Because of the presence of lift and moisture
availability, there will likely be showers and a possible
thunderstorm or two associated with this frontal system.

As the system moves eastward through our area, rain chances will
decrease rapidly. Tuesday night through Thursday, the weather
will return to a neutral synoptic pattern, and the conditions will
return to a normal state. There is a chance of some more showers
and a weak cold front to develop towards Wednesday into Thursday
of next week, but there is still a lot of uncertainty in the
models surrounding this event. Msw

Aviation VFR conditions prevail at all terminals and likely
through the forecast. There may be temporary brat a few sites like
btr hum msy dropping them to MVFR but otherwise expectVFR
conditions. Cab

Marine High pressure currently sitting over the area will
begin to slide northeast tomorrow. This will lead to return flow
eventually setting back up Saturday night or Sunday. Winds will
still be on the light side until late Monday as a cold front
approaches. The cold front is expected to push through the coastal
waters overnight Monday night and may bring moderate to strong winds
of the coastal waters. Cab

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.
