Updated for 18z aviation discussion.

18z TAF discussion:
low stratus deck and areas of moderate to heavy rain will continue
to make for poor flying conditions through most of the period.

Ceilings expected to remain MVFR to ifr, with even some lifr
ceilings being reported. Some possible clearing of ceilings late
in the period as drier air tries to move into the area from the
north and rain chances diminish. Nf

Short-term forecast thinking remains the same, however some
changes were made to update short-term elements based on latest
radar trends and hi-res guidance. Isentropic lift over the frontal
boundary will continue through this evening, keeping overcast with
low stratus and rain chances in the forecast. The best upper-level
lift and deepest moisture will be focused north of the natchez
trace today, thus focusing the greatest precip amounts generally
across the delta parishes counties north and east through the
grenada area. A limited amount of elevated instability will allow
for some isolated rainfall rates of one-half inch per hour or
more, however most of the rainfall will come through steady
accumulating one-tenth to one-quarter inch per hour. Due to the
potential for higher rates mixing in with the steady accumulating
rain, we will keep a limited flood threat area in the hazardous
weather outlook and graphics through this evening. Temperatures
will hold steady through today as cloud cover and precip limit
solar heating. Conversely the overnight low-level cloud cover
will also limit the cooling potential, so min temps for most areas
will only be slightly cooler than afternoon high temps. Nf
prior discussion below:
today and tonight: mid level ridge anchored off the southeast us
coast continues to stream a moist southwest flow up and over the
cool airmass in the lower levels. This is resulting in increasing
isentropic ascent and widespread rains breaking out over
northwestern sections. The best corridor of ascent will setup over
the northwestern third today as deep moisture (pws above 2
inches) is tapped from the western gulf of mexico. It is also in
this corridor that the models are showing a stripe of maul with
pockets of elevated cape. In addition to the rain, have mentioned
a slight chance of thunder in these areas.

The mid level ridge over the gulf will begin to nose northward
tonight across the southern plains. With winds aloft gradually
veering and weakening as a result, the rain should slowly begin to
taper off, especially after midnight. 26
Wednesday through Monday: clouds will linger much of the day
Wednesday as moisture aloft remains a fixture over the cwa.

However, rain chances will come to an end during the morning
hours, as high pressure at the surface builds south into the
region and drier air at the surface advects into the region. Highs
Wednesday afternoon will range from the lower 60s to middle 70s,
and lows Wednesday night will range from the upper 40s north to
middle 50s south.

High pressure at the surface shifts east of the CWA Thursday through
Friday, causing winds to swing back around from the south.

Conditions will begin to warm during this time, with more breaks in
the clouds being observed as well. However, this will all be brief
as a broad trough aloft swings southeast into and through the region
late Friday and over the weekend. Currently, this is progged to
send yet another cold front south into and through the cwa. As a
result, rain chances begin increasing late Friday through Saturday,
while coming to an end early Sunday morning.

High pressure yet again builds into the region Sunday into Monday.

Northerly flow will bring another bout of cooler drier air to the
forecast area during this time. Highs both Sunday and Monday will
range from the mid 60s to lower 70s. Lows Sunday night will be
chilly as they currently look to fall into the 40s areawide. Then
Monday night, temperatures will be slightly warmer as they range
from the upper 40s to lower 50s. 19

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
