18z aviation update...

Prev discussion issued 641 am est Thu nov 15 2018
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.

Atwell
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.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
