...FLASH FLOOD WATCH IN EFFECT THROUGH FRIDAY MORNING...

.Rainfall amounts from five to eleven inches have occurred since
late yesterday across the Pine Belt and portions of eastern
Mississippi and widespread flooding is occuring. Heavy rainfall 
will be transitioning to the east of the area through daybreak, 
but some precipitation will continue into the morning hours and 
the further rainfall will keep water levels from falling rapidly. 
In addition, rivers are starting to rise from all the recent rain 
and will continue to rise in many spots through the next few days.
In short, just because rain is starting to let up you should be 
very cautious of flooded roadways and remember to turn around, 
don't drown.

Area forecast discussion, Dec 25, 11:47 PM CST, 3 hours 57 minutes before
Area Forecast Discussion...UPDATED
National Weather Service Jackson MS
1147 PM CST Tue Dec 25 2018

.UPDATE...
Updated for 06Z aviation discussion

&&

.AVIATION...
06Z TAF discussion:
Most TAF sites will deal with some patchy fog reducing
visibilities to MVFR overnight, otherwise intermittent VFR
ceilings will periodically develop and move over. HBG and PIB will
see denser fog develop in those area with IFR/LIFR conditions from
26/08Z to 26/14Z. Thereafter, conditions improve to VFR and stay
as such at all TAF sites through the end of the period. Winds look
to stay southeasterly at 5 to around 10 knots with gusts from 20
to 25 knots during the afternoon and continuing through the end of
the period./26/

&&

.DISCUSSION...
Expect isolated light rain showers tonight for mainly western and
central portions of the area as a boundary lifts north through the
region. Patchy fog will be possible later tonight across mainly
southern portions of the area. Low temperatures will be in the mid
40s to lower 50s. No major changes were needed to the current
forecast. /27/

Prior discussion below:

Through Wednesday: The sun has been more plentiful that previously
anticipated across much of the area this Christmas Day, allowing
temperatures to soar through the 60s to near 70 in some areas.
Meanwhile, clouds have persisted along the US 82 corridor, where
temps remain in the 50s and upper 40s in North MS. The disturbance
which sparked off isolated showers in these areas earlier today is
now moving away toward the Mid-Atlantic coast. Tonight, a pseudo-
warm front will develop across the area as our next storm system
begins to take shape over the Southwestern states. As this subtle
boundary lifts northward across the area, clouds will increase and a
band of isolated/scattered showers will lift northward through the
night. The greatest chances for very light rain amounts will be over
the western half of the area. These showers are expected to lift
north of our area by Wednesday morning. Patchy fog will be possible
across Central LA and South MS around daybreak, but for now it
appears considerable cloudiness will prevent fog from being
widespread. Low level southeasterly flow will pick up through the
day as the developing surface low deepens over West TX. By late
afternoon and early evening, showers may begin to move into the
MissLou region as deeper moisture and increasing lift advance into
the region. In spite of the clouds, it should be relatively warm
again with highs possibly touching 70 in a few areas. /DL/

Wednesday night through New Years Eve...

An active weather pattern will take shape which should feature
several rounds of rain and some storms.

The first weather system to affect our region will begin to
develop across the Southern Plains by Wednesday night. The upper
ridging that has been over us will push off to the east as an
upper trough digs across west Texas and New Mexico. A deepening
area of low pressure will track across Kansas and Nebraska and
toward the Upper Mississippi Valley region. Moisture will stream
into the region ahead of this heading into Thursday with PW values
increasing to around 1.6 inches by Thursday morning. Some showers
could be ongoing by daybreak Thursday but the bulk of our expected
weather will come later into the afternoon through Thursday night.
A cold front will push into the region, with a line of storms
ahead of it. Dewpoints are forecast to reach into the lower to mid
60s across the area, as well as vertical totals around 25-27C and
sufficient low and deep layer wind shear. This would suggest
potential for damaging winds and of course tornadoes. Going
marginal risk is sufficient for the time being and will be
continued.

The other risk with this system will be from heavy rain and
flooding potential, particularly in the east and southeast part
of the forecast area. Ample moisture will be in place and with a
slower moving system that appears to hang up in the east and
southeast, this could bring potential for 2-4 inches of rain here.
Elsewhere, 1-3 inches will be possible. Inherited limited and
elevated risks appear fine but did expand the elevated risk just a
little to the west.

With strong ridging across the Atlantic, this front will hang up
around our area and keep rain chances in the forecast, especially
for locations along and south of I-20 through the remainder of the
year. A few areas of low pressure look to develop along this
stalled front which could bring rain to the entire area and
potential for some stormy weather as well, particularly around the
New Year. Hope people got some umbrellas or rain jackets for
Christmas, because it looks like they will be put to good use over
the course of the next week! /28/
