Area Forecast Discussion...UPDATED
National Weather Service Austin/San Antonio TX
923 AM CDT Thu Apr 13 2017

.UPDATE...
Area radar data continues to show an area of showers and
thunderstorms ongoing across the southern Edwards Plateau and Rio
Grande Plains this morning. An MCV has formed and this has helped
maintain convection. We do see some slow warming of cloud tops, which
argues for decreased activity. However, we are seeing some new
development ahead of the MCV and have opted to increase rain chances
for areas mainly west of Highway 83 through mid-morning. We will need
to keep an eye on any outflow boundaries produced by this convective
complex as this could provide a focus for afternoon convection
farther east across the Hill Country and I-35 corridor.

&&

.PREV DISCUSSION... /ISSUED 626 AM CDT Thu Apr 13 2017/

AVIATION...
SHRA/TSRA SW to NW of KDRT will continue to drift E for a few hours
this morning and have mentioned at KDRT through 15z when they will
dissipate. ISOLD/SCT SHRA/TSRA later this morning into afternoon and
ISOLD SHRA/TSRA western areas tonight into Friday are expected.
PROBs are too low to mention, although will monitor radar and model
trends for possible updates. IFR/MVFR CIGs and patchy IFR/MVFR VSBYs
will lift to VFR this afternoon with some areas becoming SCT. CIGs
will lower to MVFR late this evening and IFR overnight. VSBYs ranging
from LIFR to MVFR are possible in SHRA/TSRA. SE winds 5 to 12 KTs
increase to 10 to 18 KTs by midday and then decrease to 5 to 12 KTs
tonight.

PREV DISCUSSION... /ISSUED 455 AM CDT Thu Apr 13 2017/

SHORT TERM (Today through Friday)...
A broken line of showers and thunderstorms are ongoing across
portions of the western Edwards Plateau. These will continue their
east/northeast motion, potentially impacting the northern reaches of
Val Verde and Edwards County this morning. Severe threat is minimal
as storms will continue to weaken as they move eastward. Meanwhile,
some patchy fog may develop across portions of the coastal plains
this morning.

As the upper ridge shifts eastward, the upper disturbance will
continue its advance northeastward toward northern TX/OK through the
daytime hours of Thursday. Ample moisture due to southeasterly winds
advecting moisture from the Gulf, weak dynamics from the base of the
lifting upper ridge, as well as sufficient instability, will yield
the chance for isolated to scattered thunderstorms across much of the
region today. Severe threat should be minimal given the weak shear
profiles, which will be supportive of pulse-type thunderstorms.
Friday will be fairly similar to Thursday, with isolated showers and
thunderstorms possible.

LONG TERM (Friday Night through Wednesday)...
From Friday evening through Monday morning, small scale disturbances
embedded within the zonal westerly flow aloft will yield unsettled
weather. Surface winds will continue to be out of the southeast and
will continue to advect ample boundary layer moisture into south
central TX. This moisture will yield ample cloud cover and slight
chances for showers and thunderstorms, but accumulated rainfall
amounts are expected to be minimal. However, models are suggesting a
slightly more potent shortwave trough coming across northern Mexico
and ejecting into south central TX on Monday night into Tuesday
morning. Significant severe weather or heavy rainfall does not
appear likely from this system at this time, but is worth keeping an
eye on. Beyond this, the GFS continues to hint at embedded
shortwave activity through the middle-to-end of next week.
