.DISCUSSION...
Issued at 415 PM CDT Fri May 22 2026

In the near term, the morning MCV responsible for a weak brief
tornado in Hinds County and areas of heavy rainfall has moved off
to the east, but a lingering moist convergence axis, located
roughly along the I-59 and Hwy 45 corridors, has been the focus
for renewed convective development during peak heating. Additional
intense rainfall rates and strong updrafts are resulting in a
renewed low-end severe/flash flood threats for the next few hours
in those areas. Later tonight, we could see the nocturnal
enhancement of ~ H850 winds and moisture transport support
additional flash flood concerns. Following days of heavy rainfall,
many locations are becoming more flood prone and sensitive to
additional heavy rainfall, and so have continued the limited flash
flood threat messaging in our HWO graphics through tonight.

Looking ahead, heavy rainfall threats will continue through the
weekend and into next week as a persistent trough to ridge
longwave pattern remains anchored over central and eastern CONUS.
This will continue to bring our region a steady stream of
subtropical moisture with seasonably high moisture content, and
multiple upper level perturbations that will provide lift to help
initiate additional rounds of convective rainfall. Once we get to
about Sunday, a greater threat for flash flooding should evolve
as a more favorable set-up and coupled upper level jet
interaction team up with the very moist air to bring a more
widespread heavy rainfall threat. As of now this appears it will
be over mainly western/southern portions of the area and have
maintained an "elevated" flood threat in this area.

Otherwise, it appears the thermodynamic/shear profiles will not
be particularly favorable for severe weather concerns given the
deep moisture and influence from the southeast CONUS ridge, but as
is the case in the near term, we'll need to monitor for marginal
tornado risks given the potential for enhanced low level shear in
the very moist air. As previously mentioned, it's difficult to
find an end to this wet pattern in the guidance through most of
the remainder of the month. /EC/

.AVIATION...
(00Z TAFS)
Issued at 654 PM CDT Fri May 22 2026

A very humid airmass will maintain threats for MVFR/IFR category
stratus through the weekend with ceilings most hazardous during
the early morning hours. TSRA should be at their greatest threat
during the peak heating hours, but could occur at just about any
time of the day or night. Surface wind will be on the light side.
