.AVIATION...
VFR conditions have returned to Austin and San Antonio. MVFR CIG
remains at DRT, but should scatter out over the next hour or two. VFR
conditions will prevail at all airports through the afternoon and
evening. A cold front will approach the region tonight, but before it
arrives CIGs will drop to IFR in San Antonio and Austin by around 09Z
and at DRT by around 12Z. The front will bring a wind shift to the
north and a chance for showers and thunderstorms during the mid-
morning in Austin and San Antonio. We do not expect any precipitation
at DRT, but there is a slight chance. Rain chances will end during
the early afternoon and winds will increase and become gusty,
possibly as high as 25 kts.

.PREV DISCUSSION... /ISSUED 328 AM CDT Sat Oct 14 2017/

SHORT TERM (Today through Sunday)...
Another morning with abundant cloudiness and patchy to areas of fog
across the area, especially east of Interstate 35. We are monitoring
closely surface observations as dense fog areas have already
developed to the south and east of our CWA. Otherwise, a cloudy
morning is expected across much areas with party cloudy skies this
afternoon. There is a slight chance for showers and thunderstorms
across the coastal plains by mid to late afternoon, if the cap
erodes. Highs are expected to range from the mid 80s across the Hill
Country to the lower 90s east of Interstate 35 and the southwest part
of South Central Texas.

Clouds return this evening as well as patchy to areas of fog in
advance of a cold front coming into our area from the north. The cold
front is expected to arrive between 6 and 7 am Sunday to the
northern part of the Hill Country and southern Edwards Plateau. All
HiRes models bring a broken line of showers and thunderstorms across
the area with activity decreasing as it pushes to the south and dry
and cooler airmass mixes down. Rain chances come to an end by mid to
late Sunday afternoon. Rainfall amounts are expected to range from
few hundredths to one quarter inch.

LONG TERM (Sunday Night through Friday)...
A dry and cool airmass will spread across the area Sunday night into
the first part of the week with lows in the mid 40s across the Hill
Country on Monday, Tuesday and Wednesday mornings. Highs will be
averaging from the mid 70s to lower 80s through mid week with a
warming trend expected for the latter part of the work week.
Have introduced slight chance of showers and thunderstorms for
Friday across the eastern zones as medium range models suggest an
increased area of tropical moisture to move into the mid and upper
Texas coast in combination with the passage of an upper level
disturbance.
