Area Forecast Discussion
National Weather Service Jackson MS
312 PM CDT Fri May 22 2020

.DISCUSSION...
Tonight and tomorrow...

A warm day has unfolded across the region. Temperatures have reached
the upper 80s and even 90 degrees at a few locations. Showers and
storms have occurred across the southeast part of the state and
these will continue through the afternoon. With decent lapse rates,
there could be a strong storm or two with this activity. Storms
should diminish with loss of daytime heating. As an upper level
storm moves to the northeast of the region, there are some
indications that the remnants of an MCS that will move through
portions of the Southern Plains and into Arkansas could move into
the Delta later this evening into overnight. Per hi-res model
guidance, the most likely time for this would be after midnight, but
confidence is not high that this will remain together and have left
out of the forecast for now. Later shifts may want to monitor this
potential. It is possible that this decaying system may leave a
boundary for focus on storms tomorrow. It appears the best chances
for storms will be around the Natchez Trace corridor. Highs tomorrow
will once again be warm with more locations potentially reaching
into the lower 90s. /28/

Tomorrow night through Thursday...
Looking at 500mb, there are three predominant lows...one well
defined over the upper Ohio River Valley, one over the NWrn CONUS,
and a third developing over the Missouri River Valley. The third low
is expected to continue to deepen, cutting off and moving a little
more slowly eastward, but finally kicking the eastern low out to the
Atlantic coast. At the surface, a Bermuda High and a developing low
pressure region over the Rockies keeps the flow southerly in the
southeast, pulling plenty of warmer air and moisture into ArkLaMiss
and surrounding areas.  This will ultimately mean a continued hot
and muggy holiday weekend.  With temperatures in the upper 80s/lower
90s, and moisture increasing through the weekend, there will be
plenty of general instability...but the lapse rates will lessen
slightly with time. Showers and thunderstorms will continue to be a
threat, particularly in the afternoon/evening hours with a steady
diurnal impact.

As the week progresses, the low over the NW will see a series of
shortwaves pivoting through the trough...deepening the
trough/amplifying the pattern and perpetuating the inflow of hot
temps and moisture. Sets up a forecast with persistent temps about 5
degrees above normal and scattered showers and thunderstorms,
particularly in the afternoon...but also with varying degrees of
isentropic influence with the amplifying pattern.  PW values range
from 1.4-1.8 through midweek, but the lifting mechanism is the
trick.  Regardless, a hot and summery pattern in place through the
forecast. /HJS/

.AVIATION...
18Z TAF discussion:
VFR conditions will mostly prevail through the period. Some
showers or thunderstorms may affect KHBG/KPIB/KMEI through this
evening before diminishing. MVFR to potentially IFR ceilings will
occur after midnight and before daybreak tomorrow. These should
lift by 14Z tomorrow back to VFR. Additional showers and storms
will be possible again tomorrow. /28/
