with this morning's cold front a distant memory as it crosses the
central gulf this evening... Lowering dew points under weak winds
and clear skies will create an unseasonably cool early Monday
morning. Certainly a jacket morning for all of those early risers
as clear skies and near calm winds aid in having ambient
temperatures cool closer to 40 degree interior dew points. Inland
minimum temperatures will be around 8 to 12 degrees below normal
while near coastal readings will be within a few degrees of normal
(low to mid 60s). A beautiful sunny day tomorrow as afternoon
temperatures warm into the very do-able upper 70s to lower 80s
under 20-30% relative humidities. A secondary shot of colder air
Tuesday will regulate afternoon warmth to the lower to middle 70s
followed by a very crisp early Wednesday morning in the areawide
(inland) 40s upper 50s (coast). The next chance of rain looks to
be at the end of the week in association with the next cold
frontal passage. 31

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.
