Severe Thunderstorm Warning 192, NWS Jackson, MS

Area Forecast Discussion
National Weather Service Jackson MS
241 PM CDT Thu May 5 2022

.DISCUSSION...
Through Friday: A shortwave has initiated convection from near
the MS River south of Memphis, WSW through south of Pine Bluff
and extending from SE Arkansas into NE Texas. These storms will
gradually converge into our Delta areas over the next few hours
and progress east and northeastward through the evening. Some of
these storms have already exhibited severe characteristics over
the past hour or two, and as they move into a region of moderate
to strong instability and strong deep layer shear over our
northwestern zones this afternoon into this evening, severe
weather will continue to be a threat. Given the more linear storm
mode and weak directional shear, damaging wind gusts should be the
primary threat, but with any discrete cells, large hail is
possible, as we've already seen across AR this afternoon. The
tornado threat is relatively low but can't be ruled out. While the
greatest severe focus will be from northeast LA across into
northwest and north MS, additional convection will spread across
much of the remainder of the area through the evening. As it does
so, it will likely become increasingly boundary-parallel which
should generally limit the intensity of the storms with further
southward and eastward extent as they become regularly undercut
by the cold pool. Still, isolated instances of damaging wind gusts
will remain possible into this evening, particularly for any line
segments that are able to surge more.

We may see a bit of a break behind the initial round of storms,
with lagging shower activity and isolated thunder and a more
stable airmass overspreading much of the region in the wake of
this activity. Overnight, as the main cold front pushes across
the area, redevelopment of convection is possible along and ahead
of it. Given the limited instability and unfavorable time of day,
severe storms appear unlikely at this time. However, we can't
rule out just enough instability working back in across
south/east MS for an isolated damaging wind gust early Friday
morning through around daybreak.

Lingering showers will decrease in the east through the morning,
with clearing from west to east through the day. Westerly winds
will be breezy at times during the day. /DL/

Saturday through Thursday:

The prevailing influence on our weather for this weekend through the
middle of next week will be an upper-level ridge of high pressure
strengthening and building from Northern Mexico toward the Great
Lakes. This will be as a low pressure system moves out over the
Atlantic over the weekend and then cuts off and stalls off the
East Coast, and as a deep trough develops over the Pacific
Northwest and helps to amplify southwest flow from the Desert
Southwest into the Plains. Surface troughing east of the Rockies
and surface high pressure wedged down the East Coast will support
continued warm, generally southerly flow over our area into the
middle of next week.

The effects of high pressure aloft should suppress convection,
although heat and humidity will only be on the increase. High
temperatures in the 90s are expected to be common by Monday, with
forecasted MaxT's above the 90th percentile for early May. Peak
heat index values will likely climb to around 100 degrees, which
is just shy of thresholds for mentioning in the Hazardous Weather
Outlook. But considering this will be the first round of
summerlike heat for the season, it is still highly recommended to
check on your neighbors and relatives to make sure they are
prepared for the warm weather ahead. The pattern becomes less
certain at the tail end of the forecast period, as models indicate
the low pressure system off the East Coast may begin to
retrograde and nudge better moisture and rain chances in from the
east. Or it may also erode the eastern edge of the ridge enough to
let an MCS run down toward the Gulf Coast from the Midwest at
some point. /NF/

.AVIATION...
18Z TAF discussion:
VFR conditions prevail across the region early this afternoon,
though S/SW winds are gusty in many areas. However, TS will
increase this afternoon and early evening, initially in the
GLH/GWO area, spreading south and east through the evening. Some
gusts to 50 kt and large hail are possible, and tornadoes can't be
ruled out with the highest potential for severe storms in the
northwest/GLH area. MVFR ceilings and brief visibility reductions
are possible in the heavier storms. VFR conditions may return in
many areas overnight before MVFR or IFR low stratus return toward
daybreak. Additionally, another round of SHRA or TS is possible
early Fri morning as a cold front moves through. Conditions will
begin to improve from west to east after sunrise, with VFR
conditions returning in most areas by midday. West winds will be
gusty at times tomorrow. /DL/
