Near record heat and dry weather this memorial day weekend...

Update
Strong 500 mb ridge is noted over the forecast area with rap model
showing heights of about 593 to 594 decameters today. These
levels are record heights based on sounding climatology since at
least 1995. Sfc data shows high pressure ridge around 1022 is
across the wern atlantic through northern fl and into the lower
ms valley. As such, a weak southwest flow is noted over parts of
southeast ga southward to just south of i-10. A few clouds noted
over ga just below an inversion around 8000 ft but these should
dissipate today. Not much moisture to develop some cumulus so
just few expected to form.

Main story of course, continues to be the heat, with highs in the
mid 90s to around 100. Hottest MAX temps will be in southeast ga
at about 100 to 103. Though scorching temps, dewpoints will
bottom out this aftn in the lower to mid 60s most areas which
will keep heat indices below local heat advisory criteria. Sea
breeze relief expected for the coastal areas, but unfortunately
the sea breeze will be moving relatively slow given weak synoptic
winds. We expect some records to be broken or tied today. Climate
section below denotes current records today, through Tuesday.

Aviation
PrevailingVFR conditions, though very brief cig issues at sgj due
to patch of low clouds there. Winds increase from the southeast
during the afternoon (18-19z) for the coastal tafs with the
passage of the east coast sea- breeze.

Marine
Little change for the morning cwf update. Winds will transition
from southwest to south and southeast in the aftn. Seas around 2
ft at this time but will trend up a bit late this aftn evening as
the sea breeze strengthens to near 15 mph.

Rip currents: generally low risk of rip currents due to low surf
conditions but onshore winds increase during the afternoon as the
sea-breeze moves inland. Rips will be stronger and more frequent near
structures such as jetties and piers.

Climate
Record highs at climate sites for memorial day weekend & early next week:

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.
