Area Forecast Discussion...UPDATED
National Weather Service Jackson MS
1250 PM CDT Fri Aug 9 2019
.UPDATE...
Updated for 18Z aviation discussion

.AVIATION...
18Z TAF discussion:
VFR conditions will prevail through the forecast period.
Thunderstorms/showers chances will continue through the afternoon.
Some sites may briefly drop in visibility with heavy rain, but
conditions will quickly improve as things begin to clear out. Some
patchy BR and low stratus are possible by early tomorrow morning
at some sites./JNE/
&&
.DISCUSSION...
No major changes were made to the forecast through this afternoon.
High temperatures will hover around the mid 90s with heat
indices reaching near 105-110 in most locations in the region.
Heat will continue to be the main concern in the short term
forecast period. A Microburst Composite checklist was done this
morning and we received a '5' which is lower than yesterday.
Although wet microburst chances are slightly lower than
yesterday, some storms today could still produce brief gusty winds
and localized heavy down pours./JNE/
Prior discussion below:
Today and Tonight: Weak shortwaves will continue to parade around
the northern periphery of mid level ridge today with one of the more
potent ones arriving over north MS during period of max heating.
Local microburst composite parameter indicating decent chances in
this same general area, as well. With upstream cold pool advancement
appearing most favorable through this area, will keep the marginal
severe risk going in the HWO.
Otherwise, the slow eastward progression of the ridge center will
mean another hot day in store. Local climatological data suggests
mid 90s for highs today which seems reasonable given 850 mb temps
around 20C. This with afternoon dewpoints remaining in the mid 70s
will keep heat indices 105-110./GG/
Saturday through Tuesday: Oppressive and potentially dangerous heat
will continue to escalate through the early portion of next week.
A stout mid/upper ridge will be situated from the Red River Valley
through the ArkLaTex on Saturday with a surface high centered over
the Gulf. Despite the close proximity of the ridge, considerable low
level moisture (PW progged to approach 2.5") will exist across the
region and the area will be close to passing mid level NW flow
disturbances. This will maintain good chances for rain on Saturday,
particularly during the daytime instability period. Outside of the
shielding influence of rain/clouds, heat indices may surpass 105F at
times. Given uncertainties with respect to which areas will be
impacted by clouds/rain on Saturday, we will not yet make a decision
on extending the Heat Advisory into this period yet, but one may
well be needed for at least a portion of the area.
Sunday through Tuesday, the mid/upper ridge will begin building
eastward, with the center becoming closer to our forecast area.
Increasing thermal capping associated with the ridge will begin to
limit precip coverage on these days, though rich low level moisture
will persist and scattered diurnal convection will remain possible.
With low level heights increasing, temperatures will also tick
upward toward the upper 90s in many areas with a few triple digit
readings not out of the question. Given the lingering low level
moisture, heat indices will push further, into the 110-115F range in
some areas. A Heat Advisory will almost certainly be needed, with an
Excessive Heat Warning not out of the question for some portion of
the area. We will continue to advertise a 'significant' threat for
heat stress in our HWO/graphical products mainly west of I-55. Heat
indices will be regulated to some extent by the presence of
scattered convection, though most of this development will occur in
the afternoons, allowing ample time for heat indices to rise earlier
in the day.
Wednesday and Thursday: Model agreement is somewhat better in a
much-welcomed front approaching the area as we head into the
latter portion of the week, though perhaps not reaching the area
until after the current forecast period. While temps may still run
near to slightly above normal ahead of this front and low level
moisture will remain plentiful on Wednesday and Thursday, there will
be an increase in rain chances, which will hopefully serve to
provide greater relief from the heat. /DL/
