Short term (tonight - Thursday
A moderately amplified upper level pattern continues over the conus
with troughing extending over the west coast and over the western
atlantic. In between this troughing, ridging extends from the gulf
of mexico northward through the central u.S. And will be the
dominant upper feature over the southeast u.S. For the next couple
of days. This ridging will slowly shift eastward by late Thursday
into early Friday with ridging extending over the entire eastern
seaboard.

On the surface, an area of low pressure off the mid-atlantic
coastline and associated frontal boundary continues to move eastward
into the central atlantic ocean. No effects from this system will be
felt here in florida. Behind this boundary, surface high pressure
extends south along the east coast and into the gulf of mexico. This
will keep a predominant northeast through east wind flow through the
period. Daily showers and storms will form over the inland areas and
move westward through the afternoon. Daytime highs will be well
above average with highs in the low to mid 90's region wide with
heat indices reaching 100-105 degrees.

Long term (Thursday night - Wednesday)
Upper ridging aloft over the deep south moves into the W atlantic as
a weak tutt slides over S fl Saturday. W atlantic upper ridge nudges
back over the area while tutt moves further westward into the gulf
of mexico Sun mon. Models bring upper troughiness into the central
u.S. Mid next week.

Surface high pressure axis down the eastern seaboard stretches back
across the SE u.S. And N gulf coast region into the weekend then
some models differences early next week with an old frontal boundary
feature in W atlantic. Expect generally easterly steering flow with
limited afternoon sea breezes producing isolated to scattered
showers and thunderstorms and continued warm temps daily.

or less and seas around 1 foot through the end of the week. Winds
will be on the slight increase by Friday and into the weekend with
easterly winds in the 10-15 knot range possible. With that being
said, the only real marine concerns will be higher winds and seas in
the vicinity of showers and storms that move over the coastal
waters.

Abundant atmospheric moisture will keep high humidity levels and
scattered rain showers and storms across the area for the next
several days which will preclude any fire weather concerns.

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.
