.PREV DISCUSSION... /ISSUED 428 AM CST Mon Feb 27 2017/

SHORT TERM (Today through Tuesday)...
The latest water vapor and infrared satellite imagery shows a fairly
active southwest flow aloft across south central Texas early this
morning. We have seen some weak echoes across Burnet and Williamson
counties this morning and several of the hi-res models suggest this
area could see enough lift for a few thunderstorms to develop.
Farther south across the I-35 corridor north of San Antonio and the
coastal plains, we will keep a low chance for showers this morning.
Areas of fog will also continue through mid-morning across portions
of the Hill Country, southern Edwards Plateau and Rio Grande plains.
Skies will remain cloudy across most areas through mid-morning, with
a clearing trend from west to east this afternoon. This should allow
temperatures to warm into the upper 80s along the Rio Grande to the
mid 70s farther east where clouds will linger. Temperatures continue
to warm on Tuesday with highs mostly in the 80s, except near 90 along
the Rio Grande. We will also continue to mention a low chance for
convection mainly east of Highway 83 given the warm temperatures and
an approaching upper trough axis.

LONG TERM (Tuesday Night through Sunday)...
As the above mentioned trough axis moves through Tuesday night, we
will continue a low chance for showers and thunderstorms across the
Hill Country and along/east of the I-35 corridor. We also expect a
cold front to move through late Tuesday night into Wednesday morning
and this could aid in the development of additional convection. The
cold front will quickly move east of the region by mid-morning
Wednesday, bringing gusty north winds and cooler temperatures in it`s
wake. Dry weather with near normal temperatures are in store on
Thursday. Temperatures continue to remain near normal on Friday as
some return flow begins to take shape. We will mention a low chance
for showers for areas generally along and south of Highway 90 on
Friday, with shower and thunderstorm chances expected across most
areas on Saturday and Sunday as the next upper level system moves
into Mexico.
