Area Forecast Discussion
National Weather Service Jackson MS
621 PM CDT Sun Aug 5 2018

.UPDATE...
Updated for 00Z aviation discussion

&&

.AVIATION...
00Z TAF discussion:
A cluster of weakening -TSRA/SHRA will impact KJAN and KHKS very
early in the period before dissipating altogether. VFR flight
conditions will prevail overnight and through the day tomorrow.
Some isolated thunderstorms may develop by tomorrow afternoon but
there was not enough confidence in coverage to add VCTS to any
site. Winds will be light and mainly from the south through the
period.

&&

.DISCUSSION...
Tonight and Monday: A weak mid/upper-level low and associated
vorticity maximum remains in place over Arkansas and cut off from
a belt of broad westerly zonal flow across the central portion of
the country. Two areas of ridging reside on either side of the low
with the eastern ridge centered over Georgia and a western ridge
over New Mexico resulting in a weak shear axis over the Lower
Mississippi River Valley. Isolated to scattered showers and
thunderstorms are ongoing along the Hwy 84 corridor and across
portions of the Delta. This activity is expected to continue into
the early evening hours before quickly dissipating after sunset
and loss of heating. Expect partly cloudy skies tonight with
overnight low temperatures dropping into the low to mid 70s.

By tomorrow, the main synoptic features will remain relatively
unchanged with the shear axis and vorticity maximum over the
ArkLaMiss Delta and ridging still in place to the east and west.
The better moisture quality will shift further east across
eastern Mississippi as dry mid-level air works into the Delta
from the west. This will focus any isolated to scattered
afternoon showers and thunderstorms mainly along and east of the
I-55 corridor. While locally gusty winds from any stronger storms
cannot be ruled out, area averaged forecast soundings across
eastern Mississippi reveal tall skinny CAPE profiles and weak
lapse rates which will preclude a greater severe weather threat.
Otherwise, expect partly cloudy skies with high temperatures in
the low to mid 90s. /TW/

Monday night through Sunday: Any isolated convection that develops
in the east Monday should dissipate rapidly by Monday evening.
Otherwise, near normal overnight lows in the lower 70s are
expected. Come Tuesday morning our CWA wl still be in a weakness
between a 592dam high just to our east and a second high centered
to our west. A >1018mb surface ridge is expected to continue
nosing in from the east. This high pressure surface and aloft wl
continue to limit convection and contribute to a warmer than
normal day. Tuesday looks to be the warmest day of the long term
period as highs top out 92-95F. Although wl still have a moist
airmass in place, surface dewpoints look to mix to around 70F
during the afternoon. This will result in peak heat index values
in the lower 100s. Wednesday the mid level ridge will be shunted
south as increasing troughiness over the mid/upper MS valley digs
south. This will lead to slightly cooler temperatures greater rain
chances. The main upper level trough will slide east Thursday but
broad troughiness and a stalled surface boundary will linger over
our region into Friday. Another shortwave trough looks to drop
out of the mid/upper MS valley Friday into Saturday prolonging
decent rain chances into the weekend. The rain chances and
associated cloud cover wl help keep afternoon highs cooler than
normal while morning lows run near normal through the period. /22/
