area forecast discussion

353 pm cdt Fri sep 20 2019

Discussion
Upper level ridge extends for most of the southern CONUS through
the atlantic with a surface high just off the coast of the eastern
coast around virginia to georgia. Drier air moving in from the
east has lowered pw values to around 1.5 inches for a good portion
of inland southeast louisiana and southern mississippi. As a
result, heat indices today were lower today and should generally
be less humid through the weekend. Temperatures, on the other
hand, will likely stay right in the 90s through this weekend and
into next week. The area will continue to be under a weaker ridge
through next week. -bl

Aviation
Vfr category conditions will generally prevail at the terminals
during the TAF forecast period. Isolated to scattered convection
this afternoon could impact any of the terminals, with kgpt having
the least chance. The convection should mostly dissipate after
sunset. Easterly wind flow will prevail especially for TAF sites
near the coast. 18

Marine
Strong easterly winds will affect the coastal waters through the
majority of the weekend. Because of this a small craft advisory
has been issued for the coastal waters and small craft exercise
caution for the tidal lakes. One or both may need an extension
with the eastern half of the coastal waters the most likely.

Additionally, due to the easterly flow and high tides some coastal
flooding may be possible for eastern coasts. Currently opted out
of any coastal flood advisories but that will need to be watched.

After this weekend, winds will subside and high pressure will
prevail through next week. -bl

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.
