.PREV DISCUSSION... /issued 655 PM CDT Sun Apr 2 2017/

UPDATE...
Zone forecast just updated to cancel the TOR Watch 110 for
portions of Deep E TX and NW LA, as well as the Flash Flood Watch
for these areas, as the severe/heavy rainfall threat has ended.
The water vapor imagery indicates considerable dry air entraining
across E TX and likely into portions of NW LA attm ahead of the
WCntrl TX closed low, which has ended the convection over these
areas. Now seeing a flash flood threat developing over the Srn and
Ern sections of Ncntrl LA as strong to severe convection
continues to train NE along a convectively reinforced bndry behind
sandwiched in along the warm front over Cntrl and NE LA.
Widespread 2-5+ inches of rain (with isolated higher amounts) have
already fallen over these areas today, with additional rainfall
amounts of 1-3 inches with isolated higher amounts possible this
evening before the flash flood threat diminishes overnight.

The short term progs do suggest some wrap-around -SHRA possible
late over portions of extreme NE TX/SE OK/SW AR with the parent
closed low as it begins to lift NE across OK. Did maintain low
chance pops for these areas overnight, but tapered pops back to
slight chance for the remainder of E TX/Wrn LA late.

Zone update already out...grids will be available shortly.

PREV DISCUSSION... /issued 414 PM CDT Sun Apr 2 2017/

DISCUSSION...
Extreme intense rotating tstms movg east across northern LA with
more marginally svr storms movg across sw AR. Keeping pops in
areawide this eve for any possible convection with cold front just
to the west. If nothing develops, an early eve update will most
likely reflect this. Also cancelled tor watch 109 in effect until
6 pm as storms have just cleared out of that entire area, with
areas covered by tor watch 110 remaining under the gun. A short
wave mid week will skirt northern portions of the area and a few
stg storms possible, mainly tue eve. Thereafter, a cooler and
drier airmass in place for remainder of the week, with rainfree
conditions expected thru the upcoming weekend as well. /VII/
