Short term
Higher pw values are lurking along the louisiana coastline this
morning. These 2+" pw numbers will begin to slowly move inland
today and should cover the entire area by Sunday. This will bring
the percentage of sh TS back up as well which will help to cool
things off for some. Temps hit the mid to upper 90s yesterday and
today should see close to those numbers as well. Pascagoula hit
99f yesterday for the warmest mark in the area. This may once
again be the case today. A daily cycle of sh TS will continue
through the upcoming week with activity inland during the day and
over the coastal waters during the early morning hours.

Aviation Vfr conditions will prevail at all of the terminals
through the morning hours except hum where visibilities could be
reduced to under 1sm at times as well as ceilings lowering to less
than 500 feet. Otherwise... Expect tempo groups for TS at all
terminals after 18z as widespread convection is expected.

Marine southerly to southwesterly onshore flow will dominate
through through the next 7 days as surface 1018 mb high pressure
sits over the northeastern and northcentral gulf. The waves and
winds expected to remain fairly calm outside of any thunderstorm
activity.

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.
