Discussion
An upper level long wave trough... With a couple of short wave
troughs lows rotating through... Across the eastern u.S. Through
tonight pivots offshore Fri as an upper level ridge from the western
gulf of mexico to the canadian prairies shifts east - stretching
along the mississippi valley by late fri. Surface high pressure
located in the central plains and mid-mississippi valley sprawls
down into the gulf of mexico and is reinforced from canada fri.

The week comes to an end with a dry and cool northwesterly low level
flow. Skies mostly clear to clear with no rainfall or fog expected.

Temperatures run on the cool side of normal.

For Sat through next thu: during the weekend deep layer ridging
slides across the area then exits to the atlantic mon. A long wave
trough with an associated cold front swings into the gulf Mon and
crosses fl tue. Deep ridging builds back in from the west for wed-
thu. Dry conditions prevail for the most part although the front
will bring some showers. Temperatures slowly warm to near normal
but dip as high pressure moves in behind the front.

Aviation
21 18z TAF cycle.VFR. Ocnl few CU sc. Northwesterly winds... Robust
at times

Marine
Winds increase late this afternoon and tonight... Reaching caution
speeds across some of the marine zones. A high pressure center tracks
by north of the waters fri-mon with winds diminishing and veering.

Fire weather
Drier air works in through sat... Perhaps at or below 35 percent.

While some erc values are high the winds remain below the threshold
for red flag warning for the most part. The exception is this
afternoon in hernando county where winds increased to 15 knots...

a warning will be in place through this evening. For Sun and
later veering winds will provide enough moisture... Aided by a
front tue... To preclude any low rh concerns.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
