Updated for 06z aviation discussion

Aviation
06z TAF discussion:
low stratus and some lingering patchy drizzle, left in the wake of
a cold front that's finally moved east into alabama, will continue
to clear out of the region from west to east overnight. Until it
does clear, a mix of MVFR ifr flight categories will be observed
at sites tonight, with kgtr and kmei likely observing such
categories through perhaps 14-15z Thursday. Once the low stratus
moves out,VFR flight categories will prevail at TAF sites through
the remainder of this forecast period. Otherwise, winds will
generally be from the northwest throughout the period, between
5-10 knots. 19

Discussion
Much colder and drier air continues to filter into the CWA this
evening. Satellite imagery shows the back edge of the cloud cover
nearing the mississippi river. Local radars show the back edge of
the very light rain east of interstate 55. The cloud cover and
light rain will continue to shift east through the night. The
light rain should be east of mississippi by midnight. Only minor
tweaks to cloud cover and hourly temperatures were made as the
forecast remains on track. 22
prior discussion below:
this evening through Thursday: in the wake of today's cold front
passage, some light to moderate rainfall will continue into the
evening across parts of the forecast area. Will hold onto the
limited flash flood threat in our hazardous weather outlook just a
little while longer until the last of the moderate rainfall winds
down this evening. As the axis of an upper- level trough passes
overhead this evening, rain chances will quickly drop off from
west to east. Subsidence in the wake of the trough will help to
erode low clouds overnight, and this should allow for temperatures
in northern and western parts of the forecast area to dip into
the upper-20s by tomorrow morning. The pine belt may hang onto
temperatures closer to the freezing mark if low clouds persist
closer to sunrise. Building surface high pressure will usher in
dry and sunny weather for Thursday. High temperatures expected to
be around 45 to 50 degrees (or around 10 degrees below normal for
late january). Nf
Thursday night through next Tuesday: a general west to west
northwest flow aloft will remain over the region through much of
the forecast period. High pressure at the surface building into
the region in the wake of Wednesday's front, will result in a cold
dry airmass over the forecast area as we begin the long term
period. A reinforcing shot of cold dry air will advect into the
region on Friday, as strong high pressure builds in behind another
cold front that races southeast through the CWA late Thursday
night into Friday morning. Other than a slight increase in
northwest winds and an increase in clouds over the area during
this time, no precipitation is currently expected to accompany the
passage of this cold front.

High pressure at the surface quickly builds into and through the
region Friday and through the weekend. Winds will become more
west southwesterly allowing conditions to warm a bit Saturday into
Sunday. A weakening boundary will drop south into the region on
Sunday, but again looks to currently result in only a slight
increase in cloud cover over the cwa.

Through the course of the day Monday and into Tuesday, conditions
will continue to moisten over the area. By late in the day Monday
and overnight, rain chances will increase as another cold front is
currently advertised to shift east through the region. Rain will
gradually exit the eastern half of the CWA through Tuesday morning,
as high pressure and another cold dry airmass advects southeastward
into the lower mississippi river valley. 19 27

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.
