Update
Temperatures today are expected to rise into the low 60s and then
dropping into the 40s overnight. Winds will be predominantly out
of the north and northeast today with high pressure to our north.

A relatively dry frontal passage will bring increased clouds
throughout the region tonight with some light precipitation in
the northwestern areas. A few ice pellets or flurries are possible
mixing in with the rain in the area north and west of alma
tomorrow morning as the cold air filters in. No matter what
happens with freezing frozen precipitation it is going to be a raw
and cold morning in that area. No significant accumulations of
ice or snow are expected.

A cold airmass is expected to dominate the entire area tomorrow,
resulting in strong cold air advection and dropping temperatures dry
conditions through the day. Low temperatures Wednesday night for
most areas are expected to be in the 20s, so hard freeze
conditions are expected especially in areas with critical
vegetation and crops.

Aviation
Vfr conditions will prevail through the period. Winds between 5-10
knots out of the northeast, becoming light and variable at night.

High clouds will increase through the period.

Marine
The pressure gradient will weaken today as high pressure builds
into the region but seas will be slow to subside over the offshore
portion. For that reason a strong cold front will push through
the atlantic waters on Wednesday, with small craft advisory
conditions developing once again. High pressure will then build
into the region from the west through the end of the week. High
pressure is then forecast to build east of the region late in the
weekend.

Rip currents:low risk of rip currents southeast georgia beaches,
and moderate risk of rip currents northeast florida beaches today.

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.
