...New SYNOPSIS, DISCUSSION, AVIATION...

.SYNOPSIS...
Issued at 232 PM CDT Fri Jun 16 2023

Thunderstorms will continue through the evening hours. A few
storms could be severe with heavy rain, hail and gusty winds being
the main threats. Sunday will bring a chance of severe storms to
most of the Midsouth, ahead of a low pressure trough lifting out
of the Great Plains. Large hail and damaging winds will be the
primary severe weather threats on Sunday.

&&

.DISCUSSION...
(This evening through next Thursday)
Issued at 232 PM CDT Fri Jun 16 2023

Showers and thunderstorms will continue through the evening hours.
Some storms can be severe with hail, winds, and heavy rain being
the main threats. Storms are training over the same areas so some
minor street flooding is possible. The good news is that storms
should diminish over the next 3 to 6 hours. We catch a break
Saturday as upper level ridging will limit storm chances. This
ridging will be brief, ahead of a progressive trough lifting
through the plains. We still have a Slight Risk over the Mid South
for Sunday, and we expect this area to be expanded and possibly
upgraded. The unfortunate thing is guidance still is struggling
with timing of storms on Sunday. We expect some prefrontal
convection on Sunday morning, but the more significant storms that
carry the greater chance to be severe should occur in the
afternoon and evening hours on Sunday. For early next week,
the medium range models are consistent in forming a cut-off low,
centered over middle and east TN. Scattered, mainly daytime storms
will be possible east of the MS River. To the west, an upper
level ridge will build through the plains, providing midsummer
like heat and dry conditions.

&&

.AVIATION...
(18Z TAFS)
Issued at 232 PM CDT Fri Jun 16 2023

Upstream convection over northwest and central Arkansas combined
with peak afternoon heating will be the focus for showers and
thunderstorms at TAF sites this afternoon and evening. Convective
initiation is anticipated to occur in the 19-21Z timeframe at TAF
sites and last into tonight. Instability may be weak enough to go
with prevailing VCSH for a few hours but enough elevated
instability justifies a mention of VCTS for the 4-8Z time frame
tonight. Mainly VFR conditions outside of thunderstorms and light
winds expected through the period.
