.PREVIOUS DISCUSSION /Issued at 246 PM CST/...
Upper low has moved across MS river valley and eastward across TN,
with low clouds slowly eroding across ne TX as trailing wk warm
frontal boundary movg nwd. Fog and or low clouds expected
overnight by around midnight as se winds run moisture across a sfc
based inversion. Increased se winds and deepening southerly flow
will disrupt these conditions durg early mrng and with amplified
short wave ridging ovhd, expect a rapid warmup Sunday with highs
either side of 80 degrees for all but mainly OK/AR portions of
area what may remain in the 70s. Deep upper trough will produce a
well defined axis of mstr and instability running north to south,
reaching extreme western CWA by eve, although a few stray cells
possible out ahead of axis. Stg storms possible with moderate low
lvl shear to the mix, with convection weakening into Monday as
this shear diminishes. Upper low gradually closing off from parent
trough and dipping well into the gulf Tuesday night, with low pops
eastern cwa diminishing before Wednesday. Trailing cold front will
enter a fairly dry regime just before the wknd and only isold pops
for eastern cwa along this front. More seasonal temps in store the
following wknd after this front./VII/.
