Area Forecast Discussion

.UPDATE...

See the 06Z aviation discussion below.

.PREV DISCUSSION... /issued 847 PM CST Sun Mar 6 2022/

UPDATE...
/Mesoscale update/

Modest instability remains in place this evening,
mainly along and west of the MS River. However, with the cooling
of the boundary layer we're seeing increasing convective
inhibition which is significantly limiting convection across the
CWA at this time. The only storm in the area is passing just to
the north of Clay County and has had a history of tornadoes and
funnel clouds. Once this cell passes northwest Clay, we'll likely
be in a lull for a few hours. Dynamics have been modest across the
Mid-South this afternoon and evening, but we're beginning to see
the stronger forcing for ascent overspread the area per the latest
water vapor loop.

A few warm advection showers continue across the delta and near
the Memphis area, but this activity is not a concern. The NQA VWP
is depicting 2-3 kft AGL winds near 50 kts, a substantial increase
over the past hour. This strengthening low-level jet will lengthen
hodographs overnight ahead of the approaching cold front. Deep-
layer shear will be strong overnight and will assist in
maintaining a QLCS as it moves through AR and across the MS River.
The RAP 0-3 km AGL shear vectors are oriented roughly boundary
parallel which isn't really conducive to mesovortex generation.
However, the storm-relative helicity (both in the 0-1 km and 0-3
km layers) will be quite strong at 200-300 m2/s2 (or greater in
some areas). Recent VWP hodographs are indicating quite a bit
more SRH that what the RAP is suggesting. With that in mind, the
primary concern along the QLCS will be damaging winds with a few
tornadoes possible as well.

The timing still looks good with the line reaching the Jonesboro
around 2 AM, the Memphis area 4-5 AM, and the Tupelo area around 8
AM.

DISCUSSION...

Currently, another warm day is occurring across the Mid-South.
Temperatures have climbed into the mid 70s to lower 80s. A front
is stalled across Southeast Missouri northeastward along the Ohio
River. A few clusters of showers and thunderstorms continue to
occur across Northeast Arkansas, the Missouri Bootheel, and
Northwest Tennessee. With CAPE values in the 1500-2000 J/kg range,
can't rule out an isolated storm becoming severe. However thus
far because the main forcing remains located back across Oklahoma,
storms have remain below severe limits. As the stalled front
begins to lift northward over the next couple of hours, the
convection will also shift northward. A lull will occur this
evening until the cold front pushes into the Mid-South. The latest
CAMs are showing this occurring around midnight. This timing will
align with a shortwave trough that will be moving into the
Midwest. With adequate forcing and sufficient instability, storms
that form along cold front will likely become severe with damaging
winds being the main threat. As instability wanes, the severe
threat will begin to diminish as sunrise approaches.

The front will continue to push to the southeast through the CWA
on Monday. There is a chance that the line of convection could
reintensify before it exits the CWA around midday producing a few
severe storms across Northeast Mississippi, but the likelihood is
small. Cooler temperatures will filter into the area behind the
front. Highs will be in the 50s with lows in the 30s.

The front will sag south and stall along the Gulf Coast on Tuesday
as low pressure develops along it.  The low will track northeastward
along the front putting the Mid-South into an overrunning
pattern. In addition, another shortwave trough will move eastward
into the Lower Mississippi Valley on Wednesday. Rain will begin
spread back into North Mississippi late Tuesday afternoon and
will spread over much of the Mid-South Tuesday Night into
Wednesday morning before tapering off from west to east.

Winds will turn around to the south quickly behind the midweek
system. This will allow highs to warm into the mid 60s to lower
70s on Thursday. The warm weather will be short-lived as a strong
arctic cold front will move into the area on Friday. Temperatures
will plummet behind the front. Questions remain about
precipitation chances with the system as models differ on
solutions. Highs on Saturday will only be in the lower to mid 40s.
However, temperatures are expected to begin to rebound on Sunday.

.AVIATION...
/06z TAFs/

VFR conds will deteriorate to MVFR conds over the next few hours
as a cold front moves into the area. Added tempos for frontal
passage at each TAF site. Expect TSRAs, MVFR CIGs, and a wind
shift to the northwest with FROPA.

Post-frontal SHRAs will continue through late morning and into
the early afternoon hours before tapering off. MVFR conds should
gradually improve from west to east by late afternoon.

This hazardous weather outlook is for portions of East Arkansas...
the Missouri Bootheel...North Mississippi...and West Tennessee.

.DAY ONE...Tonight

Strong to severe thunderstorms are expected across the Mid-South
tonight. The greatest risk will be across northeast Arkansas, the
Missouri Bootheel, and extreme northwest Tennessee where an
enhanced risk is in place. However, the threat for severe weather
will exist area wide. Damaging winds will be the primary hazard
with a secondary threat of tornadoes. Localized heavy rainfall is
also possible.

Strong southerly winds are expected overnight as well, with gusts
to 35 mph at times.

.DAYS TWO THROUGH SEVEN...Monday through Saturday

The potential for strong to severe thunderstorms will shift into
the Tennessee Valley and northeast Mississippi Monday morning.
Damaging winds will remain the primary severe weather threat.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is requested tonight through Monday morning.
Please relay any information about observed severe weather to
the NWS while following all local, state, and CDC guidelines.
