Discussion
High pressure aloft and at the surface continues to influence
conditions across the region with generally partly cloudy skies
and variable to light easterly flow. Shower activity has affected
a few southern offshore locations overnight although nothing
widespread. More of the same can be expected over the next 24
hours with a gradual increase in westerly flow aloft as the upper
ridge retreats south in response to a deep closed low moving
across the great lakes region. Surface flow will become
southwesterly Wednesday as the surface ridge weakens and moves
east into the atlantic in advance of an approaching front sinking
into the region associated with a developing low pressure system
off the mid-atlantic coast.

Wednesday will feature more in the way of cloudiness and rain
chances as southwesterly flow aids moisture transport across the
region ahead of the approaching frontal boundary. Greatest rain
chances currently appear likely extending from the nature coast
south to central interior and southwest coastal sections. As the
mid-atlantic system deepens and lifts northeast Thursday, high
pressure building across the ohio valley in its wake will force
the frontal boundary south thru the remainder of the peninsula
allowing somewhat cooler and drier air to begin filtering into the
region under northerly flow.

It appears Friday will be relatively close to average, temperature-
wise, with increasing cloud cover as northerly surface flow
gradually transitions to easterly while southwest flow aloft
strengthens out ahead of a shortwave progressing east across the
northern gulf coast. A weak surface trough area of low pressure is
expected to develop over the southwest gulf Friday into Saturday
in response to the shortwave energy and ride northeast toward the
central gulf coast and fl panhandle throughout the day Saturday,
shifting winds across the peninsula to south southeast as
moisture again increases across the region and lingers through the
weekend along with the return of above normal temps. Ridging
aloft builds across the region and into the western atlantic early
next week... With the surface ridge displaced a bit further out in
the atlantic, allowing continued south southeast flow across the
state until another front approaches heading into mid-week.

Aviation
Vfr conditions expected thru period with variable light easterly
flow increasing to southeast 6 to 8 knots by 15z, shifting southwest
by 20-21z, decreasing to light variable at southern interior
terminals after 02z.

Marine
High pressure stretching across the peninsula continues light east
southeast winds and slight seas today before shifting increasing
to southwest 10 to 15 knots Wednesday ahead of an approaching cold
front with showers and storms possible. Flow diminishes slightly
and becomes northerly Thursday before gradually shifting to
east southeast Friday and increasing Saturday. Seas generally 2
to 3 feet in open waters, light chop bay and inland waters.

Fire weather
Humidity values expected to remain above critical thresholds
throughout the period. High pressure to the east responsible for
light east southeast flow will give way to an approaching frontal
system and increasing rain chances Wednesday with west southwest
flow... Gradually shifting to south southeast during the weekend.

Rh values will drop behind the front Thursday and Friday but will
recover over the weekend.

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.
