Area Forecast Discussion
National Weather Service Jackson MS
258 PM CDT Fri Jul 3 2020

.DISCUSSION...
Tonight and Saturday: The morning thunderstorm activity in our
southwest has pushed south of the CWA and only a small area of light
rain was noted dissipating over our southwest per local radars.
With the exception of east Mississippi, visible satellite imagery
was showing a suppressed cu field over the remainder of our CWA
early this afternoon. Expect that the cu over east Mississippi
will continue to develop with isolated to scattered showers and
thunderstorms tracking to the south southwest into portions of
central Mississippi through early evening before dissipating.
There is also a chance that some of the convection firing up over
central Alabama this afternoon will shift into our east central
and southeast Mississippi zones before dissipating. Per local wet
microburst checklist a few of the storms may produce strong wind
gusts. With the exception of our southwest, temperatures are
expected to rise into the lower 90s this afternoon and combine
with high humidity to raise heat stress concerns. Wl maintain
mention of Limited Heat Stress in our HWO into early evening.
Saturday morning our CWA will still be on the eastern fringe of a
mid level high resulting in northerly flow aloft but during peak
heating our flow aloft will become even lighter than today and
from the east. This should allow for a greater coverage of
convection than we will see today. Afternoon highs will again try
to climb into the lower 90s before the convection occurs. Peak
heat indices are expected to remain just below 105 and for a short
duration therefore wl not include heat stress in our HWO with
this forecast package. /22/

Tomorrow night through Friday...

An active period of weather will persist across the area through the
remainder of the holiday weekend and into next work week. The
forecast starts off tomorrow night with ridging across the Desert
Southwest/Four Corners region and a mean longwave trough over the
Pacific Northwest. Several shortwave perturbations embedded within
the progressive northern stream flow will rotate through the
northern Rockies and into the Canadian Prairies but will remain will
to our north across the upper reaches of the CONUS. Meanwhile,
across the Gulf Coast States, global guidance continues to paint an
active stretch of weather due to weak troughing and a mid/upper-
level low closing off as we head through early next week. Numerous
to widespread showers and thunderstorms are expected each day
through at least Wednesday. A warm and humid airmass will remain in
place with dewpoints in the mid to upper 70s. This will help showers
and storms get an early start with coverage increasing through the
mid to late morning hours. A few strong to severe thunderstorms
cannot be ruled out any given day, especially where pockets of
stronger instability materialize and in the vicinity of any remnant
MCVs and/or outflow boundaries. With that being said, severe
potential will have to be assessed on a day-to-day basis via the
local microburst checklist and detailed mesoanalysis, so will keep
the HWO/graphics clear. Temperatures will remain seasonably cool
owing to mostly cloudy skies and shower/storm coverage. Highs will
range from the mid 80s to low 90s with heat index values in the
upper 90s to near 100, which will keep heat stress conditions in
check.

Heading into the later portions of the week and next weekend, the
upper weakness is progged to lift northeast into the Tennessee
Valley with the Desert Southwest ridge retrograding slightly further
west. Several disturbances are progged to rotate around the ridge
and into the Mississippi River Valley within a north/northwesterly
flow regime. This synoptic setup could yield increased MCS activity
across the area and will be worth keeping an eye on. Additionally,
while storm chances will remain, temperatures will rebound as the
upper weakness moves away from the area with seasonable summer warmth
returning amidst relatively less cloud cover. /TW/

.AVIATION...
18Z TAF discussion:
VFR conditions were observed at 1730Z and VFR conditions are
expected to continue through this evening. A few isolated TSRA
will develop around the area later this aftn but miss the TAF
sites. A brief period of MVFR vsbys from 09-13Z Saturday is
possible areawide. Otherwise, VFR conditions will prevail through
Saturday morning before aftn convection occurs. /22/
