Short term today through Friday
The final wave of precipitation is moving across the area with
several north-south oriented lines of heavier rainfall moving
across the area. The rainfall will taper off from west to east as
the upper low lifts through the tennessee valley by daybreak
this morning and continues into the ohio valley by this afternoon.

The associated surface low will also lift to the northeast, over
the carolinas by early this afternoon. As the upper level trough
base shifts over the carolinas by 18z, this will push the moisture
flow off the gulf of mexico east of the forecast area, allowing
drier air to filter into the area under west-northwest flow aloft.

Have continued the flood watch through 7am, with the areas of
heavy rains lifting northward over the same area, we may see
isolated flash flood warnings through this morning until the
moderate rain tapers off at most locations by noontime. Please see
the flood watch for more information. Surface winds will also
shift from northeast to northwest and west this morning, which
will also aid in drier air filtering into the area. While low
clouds will be slow to lift through this afternoon, as the upper
level trough lifts away from the forecast area it will allow
surface high pressure and more zonal flow to set up which will
allow skies to clear quickly this evening. Surface winds will be
slow to diminish, with 10-15mph winds continuing until just before
daybreak. While radiational cooling will have a hard time setting
up, temperatures will drop into the upper 20s to lower 30s across
much of the forecast area and have issued a freeze warning for
tonight with temperatures below freezing expected between midnight
and 8am, please see the freeze warning for more information.

Temperatures on Friday will remain cooler than normal but should
be in the 50s, up to 10 degrees warmer than the past few days in
several locations. Have stayed close to guidance temperatures
through the period.

Long term Friday night through Wednesday
Dry weather looks like it will dominate our area through the middle
of next week. The long term period begins with high pressure over
the southeast and a broad westerly flow aloft. A frontal boundary
pushes into the tn valley on Monday but GFS and ECMWF show the
associated moisture diminishing as the front moves into ga. For now
will keep Monday dry. After that... Northwest flow aloft prevails
over the southeast... With another front crossing the appalachians
late Tuesday or early Wednesday. This front also looks like it will
be moisture starved. Temperatures will moderate through the period.

drier air bringingVFR around 00z. Winds remain from the E ne
12-18 kts but will diminish between 10-12z to 5-10kts. Winds will
shift to the NW over atl csg mcn by 15z and ahn by 18z, with wind
speeds increasing with the wind shift to near 10kts again.

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.
