Synopsis
High pressure at the surface and aloft will dominate through the
weekend into early next week. A weak cold front with little
moisture will move through the area Monday night.

Near term through tonight
High pressure both aloft and at the surface will result in dry
conditions through tonight due to large scale subsidence.

Satellite imagery this afternoon showing some cumulus
development in the southeastern midlands, where moisture is just
a bit deeper than in other parts of the forecast area. Shower
activity should remain along the coast. Calm winds coupled with
mostly clear skies overnight should lead to excellent
radiational cooling conditions. Lowered overnight low
temperatures a couple of degrees resulting in expected lows in
the middle to upper 50s.

Short term Saturday through Monday night
Ridging will remain across the region, both at the surface and
aloft, through the early part of next week. A weak cold front
will then approach the area by Monday night. Moisture will be
limited this weekend, and the forecast is expected to remain
dry, with pops near zero. Ahead of the front on Monday and
Monday night, limited moisture once again, with any light rain
they may develop along the central appalachians diminishing as
the airmass pushes east of the mountains. Kept the forecast with
the front dry.

Temperatures begin climbing back up above normal, with highs
during the weekend in the mid to upper 80s, then by Monday
temperatures will reach back into the lower 90s once again. Lows
expected in the lower to middle 60s.

Long term Tuesday through Friday
As the front becomes diffuse and dissipates, ridging builds
back into the area for the remainder of the week. Rainfall
chances remain low, and dry forecast will continue for now.

Temperatures will begin to climb well above normal, with the
potential for near record afternoon high temperatures by the end
of the period.

Aviation 18z Friday through Wednesday
High confidence inVFR conditions through the 24-hr period.

Exception may be possible brief patchy fog at ags ogb early
Saturday.

High pressure coupled with a dry airmass will continue to result
inVFR conditions at the terminals through Saturday. Cannot
rule out a brief visibility restriction at fog prone, ags and
ogb, but the chance was too low to include mention. Lamp
guidance does indicate brief restrictions at ags and ogb, but
moisture may be too shallow for any fog to materialize. Light
easterly winds will become calm overnight.

Extended aviation outlook... Brief periods of shallow fog
possible at fog prone ags and ogb through the extended period.

Cae watches warnings advisories
Ga... None.

Sc... None.

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.
