.DISCUSSION...
Issued at 253 PM CDT Sat May 4 2024

Tonight through Sunday...Isolated showers/storms will be possible
into the early evening hours, but will dissipate with skies
becoming partly cloudy overnight. A short wave will move into the
area on Sunday with more scattered showers/storms Sunday afternoon
and evening. With decent instability, afternoon heating and at least
some flow, strong to possibly severe storms will be possible mainly
for areas along and north of the Natchez Trace Corridor. A graphic
has already been issued for this potential. Highs will range from
around 80 in the west to the upper 80s in the east. The storms will
move east of the area during the evening hours. /15/

Monday through Saturday:

As a closed low pressure system cuts off over the Northern High
Plains through the early part of the work week, upper-level flow
over the Southern CONUS will increase. Ripples in the flow
interacting with a warm, moist air mass over the Gulf Coast will
continue to support mainly diurnal showers and thunderstorms through
midweek. Thursday into Friday, ridging over the eastern CONUS is
expected to flatten and allow for shortwave energy to eject east
across the Midwest and Great Lakes region. A cold front pushing
south into our forecast area during this time frame will be a focus
for additional shower and thunderstorm activity, eventually yielding
to cooler and drier air with high pressure coming out of the Plains.
