Area Forecast Discussion...UPDATED
National Weather Service Jackson MS
1156 AM CST Tue Feb 7 2017

...SEVERE WEATHER EXPECTED TODAY...

.UPDATE...
Updated for 18Z aviation discussion

&&

.AVIATION...
18Z TAF discussion:
Broken/overcast MVFR to low end VFR ceilings exist across the area
this afternoon. Scattered to numerous SHRA/TSRA will continue roughly
along and east of the Natchez Trace through mid afternoon, moving out
of the area by sunset. Brief lower visbys/ceilings will be possible
with individual storms, and some storms may produce large hail and 50
kt wind gusts. Behind the storms, VFR conditions are expected
through the early evening, but then low clouds and some fog are
expected to redevelop overnight across the south half of the area
with IFR/LIFR conditions possible, spreading northward toward
daybreak. Visibilities/ceilings will improve beginning by mid morning
and continuing into the middle of the day. /DL/

&&

.DISCUSSION...
Tornado Watch 26 has been issued for roughly the I-20 corridor
southward in MS and portions of central LA through 20Z.

Morning water vapor imagery reveals a shortwave swinging into the
Lower MS Valley promoting increasing upper divergence. This has
helped spark off a NNE/SSW oriented band of convection shifting
eastward across central and southern portions of the CWA this
morning. Through much of the morning, this convection has remained
below severe thresholds and has been increasingly elevated with
northward extent. However, convection is becoming increasingly
vigorous over southern portions of the area. The surface front
remains well back to the west across the Red River Valley, so
scattered convection is expected to continue to develop and move
northeastward across especially the southeast half through the
remainder of the morning and early afternoon as the shortwave pushes
across the region. The shortwave is expected to push past the area
this afternoon, so we're thinking the severe threat will come to a
pretty quick conclusion by around mid afternoon.

In terms of hazards, all modes of severe weather remain possible.
Our 12Z sounding sampled a quite impressive 7.8 C/km mid level lapse
rate, so large hail might be the stand out threat of the day. The
better surface based instability is expected to hang over the south
and western portions of the area around the pool of mid 60s+
dewpoints. With a ~40 kt low level jet axis sliding across the area
through the day, there will be damaging wind gust potential with
convection that can become surface based. In addition, effective SRH
in the 300-400 m2/s2 range indicates the potential for tornadoes,
particularly along and south of the I-20 corridor, where storms are
more likely to be surface based.

The severe threat over the Delta may remain more limited due to a
lack of convective development, and things may be more limited over
the north central/northeast part of the area due to lesser low level
instability, though more impressive mid level lapse rates would still
portend a hail thread.

We will continue to make incremental forecast updates to adjust to
current trends, but no significant changes are planned at this time.
/DL/

Relevant portions of the prior discussion below:

Through tonight...

Storms look to clear out by late afternoon/early evening as the
upper level trough swings over the region. Clearing skies should even
occur from west to east by late day. There might be some lingering
very light rain in the eastern part of the state into the early
evening but the remainder of tonight should be dry. The actual cold
front won't make it into the region until later in the week, which
means that cooler weather won't move in right away. Overnight lows
tonight will only be in the lower 60s with some mid to upper 50s
possible in the Highway 82 corridor. Dewpoints will still remain in
the 50s and 60s so "muggy" conditions will continue, likely leading
to some fog potential for tonight. Dense fog is likely going to be a
concern, especially in locations that saw a good bit of rain today.
/28/

Wednesday through Monday

On Wednesday into Wednesday night there will be low end chances of
rain over the east half for the period. The showers will exit the
region by early Thursday. The cold front will finally move through
the region on late Wednesday night into Thursday. Pwats will be less
than 0.50 inch for any rain to develop ahead of the front for
Thursday. In the wake of the front we will have a brief cool down
before southerly return flow brings the forecast area back into a
warming trend as we move into the weekend. Daily highs will push back
into the mild 70s over the weekend. Upper ridging will build back
over the region over the weekend in response to a closed upper low
over the southwest Conus. This will bring back more chances of rain
for the weekend as pwats to back to around one inch. Rain chances
will continue into Monday as another cold front passes through the
forecast area. Drier conditions will come back for Monday night.

Looking ahead the models and their ensembles show the closed low
over the southwest Conus will phase in with northern stream upper
trough pushing into the Lower Mississippi Valley at the middle of
next week as our next storm system./17/
