.AVIATION DISCUSSION...FOR 12Z TAF PERIOD...
MVFR CIGs were sporadically impacting the I-35 terminals at TAF
issuance. Thus, instead of prevailing lines for MVFR impacts, opted
to treat this with TEMPO groups for the first hour of the TAF.
Afterwards, VFR conditions are expected to prevail through the rest
of the daylight hours. A return of MVFR CIGs will be possible
overnight tonight for KSAT/KSSF.

.PREV DISCUSSION... /ISSUED 311 AM CDT Mon Jul 16 2018/ 
SHORT TERM (Today through Tuesday)...
Warm and dry conditions will prevail today and Tuesday. In addition, 
hazy conditions today lingering into Tuesday as Saharan Dust remains 
over the region. Highs warm slightly Tuesday as the ridge to the 
north nudges slightly southward.
LONG TERM (Tuesday Night through Sunday)...
Wednesday through Sunday will feature a gradual warm trend as a 
595-598 decameter high expands from the Desert Southwest into the 
northern half of Texas by the end of the week. Through the latter 
half of the week triple digit highs are expected across most if not 
all of South Central Texas, ranging from around 100 degrees across 
the Hill Country, 101-104 degrees along and east the I-35 corridor 
and near 104-107 along the Rio Grande. Mixing in the afternoons 
should prevent heat index values from getting too out of control. 
Nevertheless it will be hot with some locations flirting with heat 
advisory criteria. Will continue the heat safety messaging in various
products.
