.KEY MESSAGES...
- Arrival of drier air will result in more refreshing mornings
  and not quite as hot afternoons
- Little to no rain through the next 7 days
&&
.SHORT TERM (THROUGH FRIDAY NIGHT)...
A drier airmass will continue to filter into our region from today
into tonight with a northwesterly flow aloft and a northerly low
level flow following in the wake of yesterday`s front, which is
located to our south. Mid-level ridging centered over Mexico then
slowly nudges eastward from Friday into Friday night. Low-level
winds also turn back more easterly Friday as well. Given the dry
air, temperatures should be able to cool off faster each night and
allow for a more refreshing feel. Morning lows in the 60s should
trend common but low-lying valleys, especially across the Hill
Country, could dip into the 50s. Afternoon highs will continue to
run slightly above average but will be lower and not as hot as
majority of the past week. Partly to mostly sunny skies trend for
the rest of this afternoon while mostly clear skies are expected
through for the remainder of the period. Outside from perhaps a
brief stray shower in far southern Atascosa or Dewitt counties
later this afternoon, no rain is expected.
&&
.LONG TERM (SATURDAY THROUGH THURSDAY)...
The weather pattern remains persistent and doesn`t change much in
the long term period with mid-level ridging remaining in control
across the state and a general easterly flow in the low-levels.
Temperatures will continue to run slightly above average in the
afternoons with low to mid 90s for many near and east of the I-35
corridor while the Hill Country communities trend in the mid to
upper 80s. The mornings remain more seasonable and comfortable
featuring lows in the 60s for most while portions of the Hill
Country continue to dip into the 50s at times. Skies will remain
mostly clear to partly cloudy with not much hope for rain through
the next 7 or so days.
&&
.AVIATION (18Z THURSDAY THROUGH SATURDAY)...
VFR conditions are forecast for all area terminals through this
cycle. Northwest to north winds of 6 to 10 knots are forecast for
this afternoon and early evening. Light northerly winds are forecast
for tonight into Friday morning. The wind shifts to an easterly
direction on Friday afternoon as a result of the surface high
pressure system over northern Texas pushing to the northeast into
the middle Mississippi Valley area through the period.
