No major changes from the previous TAFs other than to include an
MVFR tempo at Waco on Friday morning. High res guidance has been
consistently hinting at a finger of low stratus working northward
along the I-35 corridor overnight. Also, isolated showers have
developed just west/southwest of Waco within the past hour within
an axis of richer low-level moisture but do not expect this
activity to directly impact the Waco TAF site overnight.
Scattered showers and thunderstorms will develop midday Friday
across most of North and Central Texas which may have
intermittent impacts on area airports. Have maintained the
VCSH/VCTS mentions through the afternoon and evening hours at all
sites. Activity will wane by nightfall with VFR conditions
prevailing Friday night into Saturday.
The isolated showers and thunderstorms that developed across
Central Texas during the late afternoon have dissipated. Outflow
from the large area of showers and thunderstorms over East Texas
has helped initiate a few showers/thunderstorms across the
extreme eastern part of the forecast area this evening. Thus, have
left some low PoPs across the area southeast of a Canton to Hearne
line through 06z.
.PREV DISCUSSION... /ISSUED 320 PM CDT THU AUG 25 2016/
North and Central Texas will remain between a developing trough
across the western states and ridge of high pressure across the
Southeastern United States. A few storms across East and Southeast
Texas may reach the eastern zones late this afternoon or early
evening but any storms that develop should dissipate around
sunset. The storms currently across West Texas along a retreating
front will not have any impacts on North Texas tonight.
The western U.S. upper trough will translate east on Friday which
will nudge the upper ridge toward the southeast coast. Increasing
large scale upward vertical motion and increasing moisture will
result in scattered showers and thunderstorms. The best storm
chances Friday will be across the eastern zones in the afternoon
where moisture and instability will be the most abundant. Some
storms may linger in the east Friday evening, but overall
coverage and intensity should decrease with the loss of surface
heating. Severe storms are not anticipated but the stronger storms
may produce locally heavy rainfall and gusty winds.
The general upper level pattern will not change much Saturday.
However, a weak low pressure system is progged to develop along
the Texas Coast which will begin to shunt the feed of moisture
into South Texas. Therefore, the chances for showers and storms
Saturday will be less than on Friday.
The upper level ridge will begin to build back to the west on Sunday
as the flow across the western U.S. becomes zonal. The
disturbance on the Texas Coast will continue to divert the best
moisture into South Texas, but there should be enough weak lift
and moisture for isolated showers and storms Sunday afternoon.
The upper ridge will become more established across the Central CONUS
Monday through Thursday which will result in seasonably hot and
mainly rain free weather with the exception of isolated storms
