Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Verified. The Iowa Environmental Mesonet's Cow matched one storm report to this severe thunderstorm warning; the first came 7 minutes after it went out.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

Shreveport, LA (KSHV), launched 12:00Z, 10.0 hours before the alert went out and 190 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area forecast discussion, Jun 7, 3:22 PM CDT, 1 hour 36 minutes before

Area Forecast Discussion
National Weather Service Jackson MS
Issued by National Weather Service Huntsville AL
322 PM CDT Mon Jun 7 2021

.DISCUSSION...

Tonight through Thursday

A upper low continues to sit over Missouri and Arkansas. Breaks in
the cloud cover this afternoon have allowed temperatures to climb
into the lower to mid 80s. With humid airmass in place (dewpoints
70 to 75 degrees), SBCAPE between 3000 and 5000 J/KG can be seen
over southern Mississippi per mesoanalysis. Models still hint at
another weak shortwave pushing into the area during the
mid-afternoon into the evening timeframe. Despite this shortwave
pushing northeast through the area, shear with it will be very
minimal. However, given abundant instability and dry air aloft
forecast in soundings, damaging microbursts still look possible
this afternoon and evening. Models do show some very weak helicity
around 150 m2/s2 moving in with that weak shortwave. Cannot rule
out a tornado totally, but that chance is very minimal. Given
fairly slow movement of activity and higher PWATS, may have to
watch out for ponding of water, minor localized flooding in some
locations. With such a humid airmass in place, lows will likely
only drop into the 70 to 75 degree range at best,especially with
cloud cover a good portion of the night.

This pattern dosn't change much Tuesday through Thursday, as the
upper low and associated longwave trough axis very slowly creeps
east. The main result will be scattered to sometimes more numerous
showers and thunderstorms on and off during that period. This
precipitation and associated cloud cover should help to keep
temperatures in the 85 to 90 degree range primarily. If cloud
cover is less than expected, highs may be a few degrees warmer in
some locations on Thursday.

Thursday through Sunday

Chances of precipitation look like they will drop off Friday into
the weekend, as the axis of the longwave trough shifts into the
eastern Atlantic. Still will seeing some isolated to widely
scattered showers or thunderstorms during this period, but should
be drier and even warmer, as highs climb into the 90 to 95 degree
range (heat index values may climb to around 100 degree by then as
well).

&&

.AVIATION...
18Z TAF discussion:
TSRA coverage is the main concern thru 18Z/08; have attempted to
break out VCTS, TEMPO, and prevailing TSRA according to
confidence. GLH and GWO will have highest impacts and coverage
thru this aftn, with PIB, HBG, and GTR a close second. JAN and HKS
do not have immediate impacts at this time but should see coverage
and impacts increase by 20Z. TSRA coverage should scale back
somewhat after midnight but may continue to be a problem more than
indicated in the TAFS. IFR ceilings will take the place of storms
for most sites (MVFR at JAN and HKS). Ceilings should lift
somewhat after daybreak, but TSRA coverage may increase near the
very end of the TAF period. /BCC-HUN/
