Area Forecast Discussion
National Weather Service Jackson MS
1241 PM CDT Fri Mar 24 2023

...New AVIATION...

.MESOSCALE UPDATE...
Issued at 908 AM CDT Fri Mar 24 2023

The near term forecast looks to be on track with the center of an
upper ridge having moved east of our area this morning. An upper
trough is analyzed west moving into the central and southern
Plains this morning. By late afternoon and evening, this trough
will be responsible for a likely severe weather event with the
details in the previous discussion still aligned with current
forecast thinking. Visible satellite imagery depicts southerly
low level flow in cumulus cloud streets, associated with
substantial moistening in the boundary layer that is expected to
continue into this evening.

Storms will be moving quickly late today due to the strong upper
level steering flow and that will mean that tornadoes may cover
long distances in relatively short periods of time. This suggests
some increased risk for long-track tornadoes. Again, as noted
previously, some of these tornadoes particularly across
approximately the northwestern half of the area could be strong.
The area in the higher risk for this possibility is denoted by the
"Moderate" (4/5) risk area in ongoing Hazardous Weather Outlook
(HWO) products. /86/

 &&

.DISCUSSION...
Issued at 428 AM CDT Fri Mar 24 2023

Today and Tonight:

The threat for severe weather today remains at a Moderate Risk -
centered on the ArkLaMiss Delta region. Apart from minor adjustments
to timing and areas in the various threat categories, no major
adjustments were needed to the short-term forecast this morning.
Details of the severe weather threat are outlined below, but the
primary message for interests across the region is that a severe
weather outbreak is anticipated in our region this afternoon into
the overnight hours, with the possibility for overnight tornadoes,
damaging wind gusts, and hail. Care should be taken today to prepare
for what you may need to do as severe weather enters the region
later this afternoon. Identify a safe shelter location (a sturdy
well-built home, a community shelter, or nearby friend or relative's
house), and have multiple ways to receive Watch and Warning
notifications through the evening.

Severe Thunderstorm details:

An upper-level shortwave trough over the Southern Rockies this
morning will continue to pivot eastward today, with a tightening
height gradient between this anomalously deep trough to the west and
anomalously strong ridge centered over the eastern Gulf of Mexico.
The result is increasing wind speeds through the depth of the
atmosphere. At the surface, a frontal boundary stretched northeast
from Oklahoma into the Ohio River Valley has been the focus for
ongoing storms overnight and early this morning. The strong
southwesterly flow ahead of the shortwave trough will not allow this
to progress too far south, and a developing surface low is expected
to eject northeast along this boundary from northeast Texas this
morning toward southern Indiana/Illinois by late tonight. Height
falls aloft and decreasing pressure at the surface will maintain the
influx of warm, moist air through the lower levels of the
atmosphere. And model forecasts show a 50-70kt low-level jet
developing on the eastern side of this surface low (over northern
LA) by around the 4PM-7PM time frame. Increasing moisture and
daytime heating will boost MLCAPE values into the 1200-1500 J/kg
range over this same sector by late afternoon, with deep-layer wind
shear increasing to 45-60 kts. An old Pacific cold front/dry line
trough south of the developing low will push eastward, and
confluence in this trough axis should serve as a focus for afternoon
convection to develop in an environment ripe for supercells.

The maximum threat area and time frame for tornadoes to develop with
this activity will be late afternoon into the early evening, across
northeast Louisiana/southeast Arkansas/northern Mississippi, as the
negatively-tilted upper-level trough and nose of the LLJ pivot over
those areas. Effective storm-relative helicity exceeding 300-400
m2/s2 would support strong tornadoes from discreet storms or
bowing line segments. Expect some upscale growth of storms into
the later evening/overnight hours, although it is possible for
discrete storms to be maintained given the fact most of the
convection will track eastward independent/east of the cold front.
General agreement among the various models is for a line of
storms to clear eastern Mississippi by around 1-3 AM early
Saturday morning, with the threat for severe storms tapering off
to the south and east from the main thrust earlier in the evening.
Hi-res model guidance indicate some isolated severe storms could
continue after midnight along the trailing outflow
boundary/weakening cold frontal boundary, but will keep timing on
local hazardous weather outlook graphics focused on the main
period of storms and adjust as finer details become apparent.

Strong gradient wind threat:

As described above, the dynamic weather system will see increasing
wind speeds through all layers of the atmosphere today. Have
outlined an "Elevated" threat area for strong gradient winds and
gusts for mainly north of Interstate 20 into the evening hours, with
"Limited" impacts to the south. Deep mixing ahead of storms this
afternoon/evening could get help some gusts into the 40+ mph range
down to the surface, and the always-windy Delta is likely to see
some sustained speeds around 25-30 mph by late afternoon. Most of
the gradient wind threat will develop shortly before the onset of
thunderstorms, so have opted not to issue a Wind Advisory for the
time being. Speeds and gusts will be near criteria, so will monitor
trends through the morning to re-evaluate if needed. /NF/

Saturday through Thursday night...Weak high pressure and drier air
will briefly build in behind the front on Saturday. Highs will range
from the mid 70s in the north to the mid 80s in the south. The
front will turn around and move back north across the area on
Sunday, with increasing chances for storms once again. With lapse
rates of around 7.0 c/km on Sunday, the main risk looks to be
wind/hail Sunday into Sunday night and SPC has issued a marginal
risk for this period. The models indicate that the boundary will
hang around the southern portions of the area on Monday with a
continued chance for showers. Another short wave will move across
the area Monday night into Tuesday with another round of storms
across much of the area. High pressure and drier/cooler weather will
move in on Tuesday, with high pressure continuing on Wednesday.
Another short wave may bring showers/storms back to the area on
Thursday into Thursday night./15/
