.KEY MESSAGES...
Issued at 1202 AM CST Sat Mar 7 2026

- Widespread showers and thunderstorms will develop early
  Saturday, focused near a slow-moving cold front. A Marginal to
  Slight risk for severe storms is in place with damaging winds
  and heavy rainfall the primary concerns.

- Daily shower and thunderstorm chances are expected into next
  week. Rainfall totals will range from 3 to 5 inches.

.DISCUSSION...
(Tonight through next Friday)
Issued at 1041 PM CST Fri Mar 6 2026

The latest NQA radar sweep indicates an uptick in thunderstorms
moving northwest Mississppi from the ArkLaTex region with lift
from warm air advection, a weak shortwave, and a low-level jet.
As we move into the overnight hours, mid-level and low-level
clouds will begin to increase, preceding a slow-moving cold
front.

Widespread showers and thunderstorms, currently oriented just
west of Arkansas, will begin pushing into the Mid-South around
sunrise, aided by this cold front. Looking at severe parameters
ahead of this line of storms, forecast SBCAPE values will be on
the order of 700-1200 J/kg, effective bulk wind shear values of
around 30 kts, and mid-level lapse rates around 6-6.5 C/km.
Though the parameter space is not optimal for a slam dunk severe
weather day, instability will be efficient enough for isolated to
scattered severe thunderstorms with a primary threat of damaging
winds.  Brief spin-up tornadoes along the main line of storms
will be a secondary threat tomorrow as 0-1km SRH values are
forecast to be upwards of 200 m2/s2 and MLCAPE values >500 J/kg.
CAMs over the last 18 hours or so have trended slower than
initially anticipated, therefore, the environment will likely
have more time to destabilize as we move into mid-morning/early
afternoon. Severe weather will be a threat all day as the severe
parameter space increases with daytime heating as this line of
storms moves southwest.

Flooding will also be a concern as PWATs surge to around 1.7",
nearing the climatological maximum for this time of the year.
Latest CAMs are in good agreement that training storms will move
mainly over the Mississippi Delta region and extend into
northwest Mississippi. Forecast QPF amounts in the aforementioned
area are upward of 3". Nuisance flooding and urban and small
streams will likely be the biggest concern, warranting potential
Flood Advisories, especially in the afternoon into early evening
hours. The cold front will push past our area by early Sunday
drying us out and leaving temperatures in the mid 60s to lower
70s. A bit of relief after the past several record breaking
temperature days.

Dry conditions will not last long, however, as the aforementioned
front lifts back north and a few shortwaves increase our shower
and thunderstorm chances once again Monday morning. By Tuesday,
our weather pattern will begin to be greatly influenced by a
closed upper-level low over Baja California. Several shortwaves
will eject from this region bringing daily rain chances through
mid-week. As far as severe weather goes Tuesday and Wednesday,
deterministic model guidance suggests a more southern track of
this upper-low leading to severe weather staying just south of
our area. However, ensemble solutions and cluster analysis
suggest a more northern orientation resulting in severe weather
creeping into southern portions of the Mid-South. Something to
keep an eye on. The latter part of the week looks dry and cooler
as a cold front pushes through Thursday.

.AVIATION...
(06Z TAFS)
Issued at 1202 AM CST Sat Mar 7 2026

An elevated warm front lifted north of MEM around 05Z, having
served as a focus for Isolated TSRA over north MS late Friday
evening. Latest GOES low level water vapor imagery showed an area
of drying and subsidence behind the warm front, while KNQA and
TMEM VAD wind profiles measured southerly FL020 winds of 45 to
50KT. While TSRA cannot be ruled out through 09Z or so, it`s more
likely that TSRA formation will await the arrival of additional
shortwave energy from the Arklamiss. And then it may -SHRA.

Of greater certainty, an MVFR cloud deck over central and
southern MS will spread northward overnight, first reaching TUP,
then MEM and MKL prior to sunrise.

00Z CAMs were in better alignment on TSRA timing on Saturday,
leading to increased confidence.

.FIRE WEATHER...
Issued at 1041 PM CST Fri Mar 6 2026

Fire weather concerns will be limited over the next several days
as wetting rain chances increase, aided by a cold front. Minimum
relative humidity values will remain above 50% through at least
early week. Warm temperatures will continue into next week.
