Area Forecast Discussion
National Weather Service Shreveport LA
302 PM CDT Wed May 23 2018

.SHORT TERM.../tonight through Thursday Night/

Isold convection has developed by mid aftn, but expecting a
little more coverage by early eve, before diurnal dissipation
occurs. With pwat values around 1.6 to 1.9, and K index values in
mid to upper 40s, very little reason to think much will be
different on Thursday, with widely sct to sct diurnal convection
and aftn temps either side of 90 degrees along with overnight
temps either side of 70 degrees. Lgt winds to continue as
well./07/

.LONG TERM.../Friday Morning through Tuesday Night/

Broad upper-trough across the central Gulf of Mexico extending
through Louisiana and into the Mississippi River Valley to maintain
a chance of mainly afternoon and evening showers and thunderstorms
trough the weekend. Surface and upper trough to move inland on
Sunday night across the northeast gulf coast near the Florida
panhandle. As this disturbance drifts north and east, upper-level
ridge to build across the Red River valley bringing hot and dry
conditions across the ArkLaTex early next week.

Temperatures from Friday through Monday to range from highs in the
lower 90s to lows around 70. Expect a gradual warming trend early
next week with high temperatures across East Texas on Monday and
Tuesday to approach the mid 90s.

Otherwise, best chances for afternoon showers and thunderstorms
through the weekend will be across northeast Louisiana and south-
centeral Arkansas. /05/

.PREV DISCUSSION... /issued 1247 PM CDT Wed May 23 2018/

AVIATION...
Although cumulus development is only taking place gradually at
some locations, isold convection has begun to recently develop
elsewhere. Juicy unstable airmass suggest that rapid development
is possible, although weak wind shear suggest cells very slow
movers and svr wx unlikely. For now, will handle with vcnty tstms
and update to localized thunder at areal terminals when necessary.
Fog possible where rain occurs but very localized and cannot
narrow down this 18z taf package. Sfc winds mostly lgt and vrbl
thru period but could be gusty near convection./07/.

PREV DISCUSSION... /issued 1037 AM CDT Wed May 23 2018/

UPDATE...
Decided not to lower pops as airmass quite juicy with K index
values in mid/upper 30s and lack of any dry layers on areal 12z
soundings. Scattered convection movg nwd across I-10 attm which
may justify high end chance across southern portions of area,
while stgr moisture convergence across nrn portions of area may
allow for more rapid development once convective temps around
upper 80s are reached in mid aftn. No update needed but reran
zones and rec to remove morning wording./07/

Arkansas, southwest Arkansas, north central Louisiana, northwest
Louisiana, southeast Oklahoma, east Texas and northeast Texas.

.DAY ONE...Today and Tonight...

Isolated to scattered thunderstorms will be possible today and
into tonight across the entire Four State Region. The best chances
for thunderstorms will be this afternoon during peak daytime
heating. This activity should slowly decrease through the evening
and nighttime hours. Brief heavy downpours, gusty winds, and
frequent cloud to ground lightning will be the primary threats.
While an isolated storm could become severe, widespread severe
thunderstorms are not expected.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday...

Scattered thunderstorms are expected each day from Thursday
through Tuesday. The greatest thunderstorm activity is expected
each afternoon during peak daytime heating, and any storms that
develop will gradually dissipate during the evening. Brief heavy
downpours, gusty winds, and frequent cloud to ground lightning
will be possible, but widespread severe weather is not expected.

A tropical low pressure system moving northward from the Gulf of
Mexico and along the Mississippi River may provide more widespread
and persistent thunderstorm chances across mainly Southern
Arkansas and Northern Louisiana Saturday through Monday.

.SPOTTER INFORMATION STATEMENT...

Activation of emergency management personnel, amateur radio
operators, and storm spotters is not anticipated through tonight.
