Aviation...
line of solid convection from south central Oklahoma into north
central Texas will continue moving east...providing a major
weather hazard for east...west aviation traffic this evening.
Latest trends indicated slow weakening...and the solid line
should become more scattered with time. By 08z the line should be
along a kdeq to ktyr line reaching a keld...kshv...klfk line between
10z and 12z if it holds together. Outside of the convection...MVFR
ceilings are expected to spread back into the area...along with
patchy MVFR/IFR visibilities in fog. The lower flight conditions will
gradually improve to VFR by middle to late morning with most
convection ending or moving east of the area. However...scattered
thunderstorms are expected to develop area wide once again during
the afternoon. /14/

Discussion...
earlier convection that generated along weak outflow boundaries
across the region has dissipated. Heavy rainfall contributed to
some flash flooding across portions of northwest Louisiana.
Otherwise...severe weather threat was limited to a few trees down
across portions of Winn Parish.

For the remainder of the night...large convective complex across
central Texas moving east. Question is whether convective line
will hold together through the remainder of the evening as it
encroaches upon Tyler/Lufkin. Current radar trends indicate a
gradual weaking along southern flank of line...with severe
weather threat continuing along Red River valley. For this
update...will maintain mention of scattered convection overnight
across East Texas as line dissipates during the predawn hours.
