Area Forecast Discussion
National Weather Service Memphis TN
928 PM CDT Sun Jun 23 2019

.UPDATE...

Evening update. The main convective line of storms has pushed off
to the east in the past hour or so. The focus now shifts to a
newer area of convection to our southwest. Latest GOES Water Vapor
Imagery shows an MCS lifting northeast across the ArkLaMiss
region. New surface-based storms have begun to fire up over
northeast Mississippi. There is a thin sliver of northeast
Mississippi that is still pretty unstable with latest
mesonanalysis data showing 2000-2500 J/kg of MLCAPE and no cap.
Combined with the LLJ, a few strong to severe storms will be
possible over the next couple of hours or so. Elsewhere, the
severe threat looks quite limited due to earlier convection.
Expect mainly light to moderate rainfall through the overnight
hours with scattered thunderstorms. About another 0.5 to 1.5
inches of rainfall is possible across the southern half of the
forecast area.

Went ahead and bumped up POPs in the short term. The HWO will be
adjusted to reflect strong and possibly a severe storm over
northeast Mississippi.

.PREV DISCUSSION... /issued 406 PM CDT Sun Jun 23 2019/

DISCUSSION...GOES-16 Water Vapor Satellite and regional WSR-88D
radar trends indicate a Mesoscale Convective System moving over
portions of Arkansas, Southeast Missouri and the Missouri Bootheel this
afternoon. A line of showers and thunderstorms with a few
scattered showers and thunderstorms just ahead of the line extend
from the Missouri Bootheel back into East Central Arkansas. As of
3 PM CDT, temperatures across the Mid-South are in the lower 90s
where rain free conditions are still occurring, and 70s where
showers and thunderstorms have already occurred this afternoon.
Short term convective trends are the primary concern in this
afternoon's forecast issuance.

The aforementioned line of showers and thunderstorms with a cold
pool will continue to push across portions of the Mid-South into
this evening. Surface based CAPE values in excess of 3000 J/kg and
0-6 km Bulk Shear values approaching 35 kts will support a
potential for damaging winds as the primary severe weather threat.
Hail is not as much of a concern as wind as freezing levels
remain quite high. Precipitable water values around 2 inches will
also support localized heavy rainfall, especially with training
thunderstorms.

Models indicate the potential for showers and thunderstorms will
continue across the Mid-South this week with another shortwave
trough moving across the area on Tuesday and a warm, moist, and
unstable airmass remaining in place across the Lower Mississippi
Valley. Overall shear is expected to remain weak with pulse type
thunderstorms being the most probable convective mode in a high
CAPE, low shear environment. In this scenario, the best shower and
thunderstorm chances would typically occur during the afternoon-
early/mid evening hours. Overall temperatures this week will
remain nearly similar over the next 7 days with highs in the 80s
to approaching 90 degrees and lows in the upper 60s to lower 70s.

.AVIATION...
/00z TAFs/

A line of storms is currently moving across the Mid-South and
should be out of the area before midnight tonight. Gusty winds
from the outflow of this line have been the main threat with gusts
reaching 30kts. Additional storms are possible overnight but
should move out of the area early morning. Confidence of timing
and extent for this additional rainfall is low. Lower clouds are
expected to persist through Monday evening. Gusts will diminish
by Monday afternoon with dry weather as rainfall moves eastward.
