Area Forecast Discussion
National Weather Service Memphis TN
1149 AM CDT Mon Apr 3 2017

.DISCUSSION... /issued 405 AM CDT Mon Apr 3 2017/

A few severe thunderstorms moved into north MS during the early
evening hours, eventually transitioning to a stratiform rain event
with a few embedded thunderstorms during the overnight hours.
Within this area of stratiform rain, a phenomenon known as a wake
low developed Sunday evening. These wake lows occasionally form in
areas of stratiform precipitation where evaporative cooling fails
to balance adiabatic warming associated with mesoscale
subsidence, resulting in low pressure at the surface. The gradient
between the wake low and the meso high associated with the
thunderstorm cold pool is what causes the strong winds. With the
convection weakening over the Mid-South, this pressure gradient
has relaxed sufficiently to allow the Wind Advisory to be
cancelled. Though winds will be gusty at times overnight, wind
speeds will generally remain below advisory criteria.

The existing area of stratiform precipitation will continue to
move off to the east this morning, leaving a more stable
environment in its wake. The upper-level trough remains to our
west this morning and will make its way northeast across the
region later today. As the cold core of this upper low traverses
the area, mid-level lapse rates will steepen, enhancing
instability as temperatures warm throughout the day. Scattered
showers and thunderstorms are expected to develop again by
mid/late morning. Model data indicates modest deep-layer shear
this afternoon, suggesting that a few updrafts could organize into
strong to potentially severe thunderstorms. That said, this
potential is relatively low and is covered nicely by the marginal
risk issued by the SPC. South-southwest winds will be a bit gusty
today at 15-25 mph.

Rain chances come to an end this evening as the upper low departs.
Subsident, drier air will settle over the area late tonight and
Tuesday, providing warm and dry weather across the Mid-South.
Temperatures are expected to warm into the mid 70s to lower 80s
with south winds of 5-10 mph. The next shortwave trough will
begin to affect the area Tuesday night into Wednesday.
Thunderstorms associated with the main wave are expected to move
east into northeast AR and the Bootheel by midnight. Farther
south, isolated showers and thunderstorms are anticipated in the
warm sector of the approaching cyclone.

The main forcing with this trough stays to the north and the
attendant cold front is progged to make an early arrival in the
Mid-South Wednesday morning. There is a bit of a cap early in the
day when frontal convergence is most favorable for convective
development but by the time the cap weakens, winds have veered
from the west and drier, cooler air begins to advect into the
region. This will keep PoPs limited to 20-30% for Wednesday and
Wednesday night. Temperatures were lowered a bit to account for
the earlier fropa, with highs ranging from the mid 60s in
northeast AR to the low/mid 70s along the Tennessee River Valley.

Low PoPs were continued on Thursday as moisture wraps around the
backside of the deepening east CONUS trough, but were trimmed
back in coverage, primarily focused on west TN. Dewpoints are
forecast to be in the 30s by Thursday afternoon suggesting much of
this precipitation could evaporate before reaching the ground.
Temperatures will be a bit cooler, with afternoon highs in the mid
50s to lower 60s. Temperatures are forecast to fall into the
low/mid 40s across most of the area Thursday night, but lingering
cloud cover should preclude frost formation.

Dry weather is anticipated across the Mid-South Friday through
Sunday. Afternoon temperatures will again be in the low/mid 60s
for much of the area on Friday, but should warm into the 70s over
the weekend. Overnight lows will be on the cool side. Expect lows
in the upper 30s and lower 40s for the most part, but some low-
lying areas and river valleys (mainly west TN and north MS) may
dip into the mid 30s, increasing the potential for a frost. We'll
continue to monitor these trends.

.AVIATION...

18Z TAF Set

Line of SHRAs, with thus far one embedded TSRA, is developing
just west of the MS River. This line is expected to develop into a
line of TSRAS as it pushes east into West Tennessee and North
Mississippi. Conditions will temporarily lower to MVFR with the
line of convection. Otherwise, VFR conditions are expected for
the remainder of the period. Gusty SW winds of 12-17 KTS sustained
with higher gusts up to 27 KTS will occur through 00Z.
Thereafter, speeds will gradually diminish to around 6 KTS.
