.DISCUSSION...
(Today through Sunday)
Issued at 211 AM CDT Mon Jul 14 2025

A bit more of an active overnight period with thunderstorms
moving across NE AR and the MO Bootheel. Storms have been able to
tap into some lingering instability, but are expected to continue
moving out of the area with southwesterly flow aloft. Will keep
some PoPs running mainly north of I-40 through the remainder of
the early morning hours, but the best coverage will likely remain
just north of our CWA. In addition, some patchy fog could develop
through sunrise near bodies of water and locations that have
experienced rainfall over the past few hours, with improvements
shortly after sunrise. For the remainder of the day, we will turn
our eyes westward to a lingering MCV as it slowly pushes towards
the area. While our daily, afternoon thunderstorm trend will
continue, this could bring an additional push for more coverage of
storms by the afternoon to early evening. Will continue to carry
40-70% PoPs, with the highest chances along and north of the I-40
corridor. Similar to the past few days, can`t rule out a strong
storm or two with periods of heavy rainfall (rainfall rates > 2")
and strong winds (30 to 50 mph). Coverage should wane following
sunset, with patchy fog in some locations again overnight.

By tomorrow, largely zonal flow aloft with little forcing will be
the main story for the remainder of the week. What this will mean
for the Mid-South is a continued hot and humid pattern, with
daily, afternoon thunderstorm chances. Surface southwesterly winds
will allow some additional WAA to the area by midweek, with high
temperatures creeping into the mid-90s by Wednesday and Thursday
for much of the area. This coupled with dew point temps remaining
in low to mid 70s will likely warrant the need for heat headlines
for at least some portion of the Mid-South. These oppressive
conditions may continue into Friday, although the forecast does
become somewhat more uncertain heading into the weekend. Of note,
through this week a weak disturbance will be trekking across the
Gulf, eventually moving into the deep south by the end of the
week. While no direct impacts are expected to the Mid-South, the
influx of moisture from the Gulf to the area will be something to
watch and observe how guidance evolves. Majority of guidance does
have a stout high pressure building into the region around this
time, which should curb any type of issues for our area. As such,
will continue to carry daily, afternoon thunderstorm chances
(30-50%) into the weekend with highs generally spanning the low to
mid 90s.

Primary short term concern is timing of IFR CIG dissipation. GOES
IR imagery showed high clouds clearing post-sunrise. This should
encourage low level mixing out of the IFR deck, with a brief
period of MVFR CIGs possible in the interim.

Otherwise, a persistence forecast in tap, with isolated TSRA
favoring the afternoon hours.
