Discussion
An upper level ridge stretching from the eastern gulf of mexico
to the upper midwest slowly moves to the eastern seaboard by late
sun as a short wave trough pushes across the gulf of mexico and a
low slides over the central plains from the west. Sprawling
surface high pressure centered over the ohio valley-carolina coast
this afternoon slides east tonight and Sun - while ridging back
across fl to the gulf of mexico.

Westerly flow aloft becomes slightly more west-southwest while
the prevailing lower level flow shifts from northeasterly to
easterly. Although the surface gradient remains relaxed enough to
allow onshore near the coast in the afternoons. There will be a
subtle increase in low level moisture with patchy ground fog later
tonight... Mainly over the nature coast and inland. Skies will be
clear to mostly clear and rain free. There will be one more night
of temperatures on the cool side then becoming near normal for
sun.

For Mon through next sat: the central plains low develops into a
long wave trough with an accompanying cold front that moves into
the gulf of mexico mon... Across fl tue... Then out over the
atlantic during wed. Deep layer ridging builds in across the area
thu- sat. The front arrives diffuse and with limited moisture...

keeping precipitation widely scattered Tue night and early wed.

Temperatures run just above normal for the first half of the week.

Then the high pressure behind the front will cool readings to
just under normal for the last half of the work week.

Aviation
23 18z TAF cycle.VFR. Few CU and few-ocnl sct ci. E winds shift to
onshore at coastal tafs aft 20-23z. Ltav aft 01-04z then E aft 13-15z.

Subtle increase in moisture will support limited br but with little
impact at main terminals.

Marine
Benign winds and seas as high pressure continues through sun. Winds begin
to shift and increase as a front approaches Mon and tracks across the
waters tue. High pressure builds in behind the front with some robust
winds at caution advisory speeds that may begin Tue night or early wed.

Fire weather

will preclude any red flag warnings. Veering winds will begin a gradual

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.
