Update
The forecast remains mostly on track as wedge conditions remain
solidly in place this morning. Morning low temperatures were the
coolest we've seen in the metro in the last 30 days and thick
overcast cloud cover remains in place with the latest guidance
suggesting it may be in place through the entire day. Patchy
areas of stratiform rain may be prevalent across the forecast area
at times as moist, gulf air overrides the wedge front ahead of a
troughing pattern currently in the ARKLATEX southern plains
region. Scattered showers are still expected to continue this
afternoon with the highest chances for western ga.

short term today through Monday ...

noticeably cooler conditions are in the offing through the short
term forecast period as a wedge of high pressure will be entrenched
at the surface. Shower and thunderstorm chances will be lower this
afternoon for much of the area given the cooler and more stable
airmass behind the wedge front. The better chance for any scattered
activity will thus be along the western periphery of the CWA with
otherwise mostly cloudy conditions for areas farther east. The
strong thunderstorm potential will also be reduced this afternoon
given the more stable airmass.

The wedge will remain in place at the surface through Monday, though
it will begin to gradually weaken. Rain chances will also be
increasing markedly from tonight into Monday as an upper trough
advances eastward towards the area. This will provide the focus for
increasing showers and thunderstorms from the west through the day
Monday. As pws will remain elevated above 2 inches, any slow moving
thunderstorm activity will continue to provide the risk for locally
heavy rainfall and localized flooding concerns.

High temperatures are forecast to run some 5 to nearly 10 degrees
below normal today and Monday under anticipated mostly cloudy skies
and cool easterly surface flow.

long term Monday night through Saturday ...

the wedge should be breaking down Tuesday as an upper trough
crosses the southeast. The upper dynamics and remaining tropical
moisture should still support likely pops for Tuesday. For
Wednesday... The flow begins to turn more northwest as a broad
trough deepens over the great lakes and into the oh tn valley
area. Gfs ECMWF agree that drier air will spread into the
southeast for the last half of the long term. Pops begin to taper
off after Wednesday and have removed pops altogether for north ga
Thursday and Friday. By Saturday it looks like the moisture will
start to surge northward again so have kept pops area wide.

Temperatures should be more toward normal over most of the
forecast area for the long term.

widespread ifr MVFR CIGS will persist through the morning hours
with at least MVFR CIGS likely through 16-18z. Some improvement to
high MVFR orVFR is possible thereafter. MVFR to ifr CIGS again
become more likely after 04-06z. While isolated to widely
scattered showers are possible today, highest coverage is
anticipated over western georgia. Shra tsra chances increase from
the west from tonight into Monday. Winds will remain from the east
at 8-12 kts through the period.

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.
