National Weather Service Shreveport LA
947 AM CDT Sat Oct 13 2018

.UPDATE...
A large area of showers and thunderstorms, associated with the
remnants of Sergio, is poised to enter our East Texas and
Southeast Oklahoma zones this morning. Our current forecast has
higher rain chances from Tyler/Rusk northeastward to Texarkana and
all points along and north of this. Precipitation forecast looks
good but will lower temperatures somewhat from northwest to
southeast to better align with where the axis of higher rain
chances is forecasted to setup. /35/

.PREV DISCUSSION... /issued 708 AM CDT Sat Oct 13 2018/

AVIATION...
For the 13/12z TAFs, the remnants of Tropical Storm Sergio are
rapidly moving across West Texas and into the Southern Plains.
Widespread convection associated with Sergio will move eastward
into the ArkLaTex region today. A frontal boundary across the
region will also serve as a focus for additional convective
development. Showers and thunderstorms will likely prevail at
KTXK, KTYR, and KGGG for most of the TAF period. KELD and KSHV
will likely see impacts by early this afternoon. KMLU should
remain dry, but convection may begin to move into Northeast
Louisiana very near or just after the end of the period. Flight
conditions will likely be highly variable but can be expected to
deteriorate as the precipitation begins. Conditions at all sites
will likely become MVFR/IFR during the overnight hours. The actual
coverage of thunderstorms is highly uncertain, so thunder was not
mentioned in the TAFs.

PREV DISCUSSION... /issued Issued by National Weather Service Fort Worth TX/

DISCUSSION...
The remnants of Sergio (formerly an Eastern Pacific hurricane) have
entered West Texas and will race eastward today. Although the early
morning convective complex is far from the Ark-La-Tex, showers are
expected to develop this morning within East Texas as moisture flux
intensifies across a stalled frontal boundary. As the more intense
convection approaches from the west later today, the upper support
responsible for its initiation will have left it behind. However, as
the associated surface low tugs our old frontal boundary to the
north, surging low-level moisture back into the region, the complex
may be able to survive its journey into the Ark-La-Tex late this
afternoon and into the evening hours. The activity will likely have
already transitioned into a linear complex along an effective cold
front, on the back side of the departing low, with a small window
for a damaging wind threat in East Texas before the convective
elements within the line diminish in intensity.

The passage of the front should spell an end to the rain chances
until a stronger cold front arrives late Sunday. The coldest air of
the season will pour into the Ark-La-Tex to start the workweek. With
troughing still upstream, the sky will remain cluttered with clouds.
As the trough digs into the Desert Southwest and eventually cuts
off, considerable cloudiness and rain chances will persist
throughout the remainder of the week. This will keep daytime
temperatures well below normal, slowing the warming trend.
