The episode as NWS JAN wrote it up.

Area Forecast Discussion
National Weather Service Jackson MS
330 PM CDT TUE AUG 2 2016
.DISCUSSION...Tonight through Thursday night
Latest satellite imagery showed the CWA under a broad mid
to upper level ridge with the high centered over the ArkLaTex region.
Area radars were picking up isolated showers and thunderstorms east
of I-55 into Alabama. On the surface high pressure centered over
Southern Georgia was bringing in weak southerly flow with
precipitable water around 2 inches. The 850 mb high was centered
over the CWA with dryer deep layer airmass to the west of I-55
toward the mean ridge center. Mid afternoon temps were in the lower
to upper 90s. Dewpoints were in the mid to upper 70s...esp in the
delta region where we have the Heat Advisory in place. Heat indexes
were above 105 degrees in some locations.
For this afternoon Hi-Res models shows our rain chances in the east
tapering off by sunset. A few storms in the east may produce some
brief gusty winds and some downpours before diminishing with pwats
near 2 inches.
For the period expect warm days and muggy nights, especially across
the northwest delta region where heat indices during the day will
exceed 110 degrees in some locations there, while elsewhere it will
range from 105 to 110 degrees through Wednesday afternoon. Thus a
Heat Advisory is currently in effect for the delta region from this
afternoon through This evening. The advisory will be expanded across
the entire cwa on Wednesday morning. Portions of the northwest delta
may be under an Excessive Heat Warning on Wednesday. That will be
determined by the midnight shift. Looking at the heat potential for
Thursday the advisory may have to be extended into Thursday evening
with heat indexes projected to be from 105 to 110 degrees at that
time. Daily highs will be mainly in the middle to upper 90s. Nightly
lows will be mainly in the middle 70s with some upper 70s in the
delta region. The mid to upper ridge will remain dominant during
the period.
Isolated to scattered showers and thunderstorms will be possible
each afternoon across much of the forecast area, especially the
eastern half. PWATs will be 1.8 to around 2 inches for some brief
downpours. The upper ridge will be positioned such that a southeast
diving complex of storms could perhaps clip far eastern portions of
the CWA. Thus, attention will be paid upstream through the period to
see if such convection indeed develops in this northwest flow aloft
pattern. Otherwise, convection that simply develops over the region
each afternoon, will dissipate around sunset each evening as daytime
heating gradually wanes. /17/
Friday through Monday...At the beginning of the period, large
sprawling mid/upper level ridge will remain anchored over the
southern CONUS with its center over TX/OK. A weakness in the ridge
will exist over the TN valley into northwest FL resulting in light
northerly flow over the forecast area. The high center will readjust
itself to the Mid South Saturday and Sunday, sliding further east
into the TN valley by Monday.
All through this period the airmass will remain quite moist with
precipitable waters remaining near 2 inches. While the mostly
diurnal convection should be enhanced by shortwaves embedded in the
northerly flow at the end of the week, the convective potential
should continue through the weekend regardless of the high center
position given the moisture availability and lack of inhibition.
The heat looks to continue to be a problem through the extended
period with highs in the mid 90s and dewpoints in the 70s resulting
in heat indices around 105 or higher in the Delta regions near the
MS river. /26/

AVIATION...
Mainly VFR conditions are anticipated as we go through tonight and
Wednesday. TSRA activity could develop farther west into eastern MS
affecting the GTR/MEI/HBG corridor from late afternoon into this
evening.
