Area Forecast Discussion

1002 PM CDT Thu Mar 14 2024

...New NEAR TERM...

.NEAR TERM...
(Rest of tonight)
Issued at 1002 PM CDT Thu Mar 14 2024

Strong-severe thunderstorms developed late this afternoon/early
this evening across northern MS/southwestern TN, in the vicinity
of a diffuse NNW-SSE oriented warm front separating dewpoints in
the m-u 50s (northeast AL) and l-m 60s (northwest AL). Present
indications are that this activity will continue to spread
eastward across the CWFA through the late evening hours (in
conjunction with the slow-moving warm front), with further
convective development aided by synoptic scale lift on the
northern fringe of a low-latitude shortwave trough moving
northeastward from the central Gulf Coast. SPC mesoanalysis
suggests that MUCAPE values currently range from 1000-1250 J/kg
within the plume of richer moisture (along the MS border) to less
than 500 J/kg along the GA border, so we generally expect the
intensity of convection to diminish with eastward extent.
Nonetheless, a favorable combination of instability and effective
bulk shear in the 35-40 knot range will exist across the western
half of the forecast are to support organized updrafts capable of
producing severe hail/wind gusts.

During the early morning hours, we still anticipate that an
outflow boundary (originating from thunderstorms well to our
northwest earlier today) will spread southeastward into the TN
Valley, likely reaching northwest AL between 2-4 AM CDT and
spreading very slowly southeastward thereafter. Although bulk
shear will remain favorable for storm organization (especially as
the southwesterly low-level jet strengthens to 30-40 knots),
instability should be progressively less of an issue, in part due
to extensive convective overturning. However, with kinematic
parameters remaining favorable, we will continue to advertise
another brief window for the potential for marginally severe wind
gusts (associated with the initial outflow boundary), followed by
a rapid transition to a locally heavy rainfall/flooding threat.

&&

.SHORT TERM...
(Friday Afternoon through Saturday Night)
Issued at 250 PM CDT Thu Mar 14 2024

After the severe and flooding threats come to an end between mid to
late Friday morning, medium chances (40-60%) of lingering showers and
embedded thunderstorms (non-severe) will be possible through the
remainder of the afternoon. Dry weather will then return to the
Tennessee Valley by Friday night and will persist through Saturday
night. With the passage of the aforementioned storm system, cooler
temperatures are expected. Highs Saturday will top out in the upper
60s to around 70 degrees, with lows decreasing to be in the mid to
upper 40s Saturday night. Much colder weather is on the way for early
next week, which is discussed below.

&&

.LONG TERM...
(Sunday through Wednesday)
Issued at 318 AM CDT Thu Mar 14 2024

[250PM UPDATE] - Not too much has changed with regards to the long
term period. After low chances of rain (10-20%) generally along and
south of the Tennessee River Sunday morning, no rain is anticipated
through at least midweek. A reinforcing surface cold front will
traverse the region on Sunday as well, bringing much cooler
temperatures and breezy conditions to the area for early next week.
Temperatures Monday night may dip into the mid to upper 20s, with
wind chills in the lower 20s early Tuesday morning! Stay tuned!

Lingering impacts will be felt on Sunday from the cold front passage
on Friday. The front will be well south of us, however a shortwave
propagating NE along the boundary will support low rain chances
(10-25%) Sunday evening with dry conditions developing overnight.
Further, a secondary dry cold front is also forecast to pass through
our area Sunday during the day, this will have a significant impact
on temperatures through the duration of the long term.

Post frontal clouds should clear overnight Sunday with mostly clear
conditions continuing through the long term period. Fortunately these
sunny conditions will be met with much cooler post frontal
temperatures. The passage of the cold front on Sunday will once again
usher in much colder and drier continental air. Monday afternoon
highs will top out in the mid 50s with overnight lows plunging into
the upper 20s and lower 30s. While overnight conditions look to be
clear, winds are currently forecast to remain elevated from the NW,
this could limit our frost potential. Conversely, this will create
morning wind chills Tuesday morning a few degrees cooler in the low
to mid 20s. Fortunately we will warm up quickly through the week with
each day and night warmer than the last with highs will be back in
the 60s by Wednesday.

&&

.AVIATION...
(00Z TAFS)
Issued at 635 PM CDT Thu Mar 14 2024

VFR conditions will continue at both KMSL and KHSV for now,
however, high chances of thunderstorms will cause decreased
ceilings and visibilities overnight into Friday morning. In
response to this, periods of IFR to MVFR conditions are in the
official TAF package with PROB30 groups allowing conditions to
fall into VLIFR to LIFR.
