.SHORT TERM...
A hot but slightly less humid day is underway this afternoon.
Temperatures have climbed into the mid and upper 90s, but
dewpoints have mixed into the 60s across most of the area which
has helped hold heat index values below 105. Drier air can be
seen working into our western counties while slightly higher
moisture content remains across the eastern 2/3rds of the area.
Cumulus development has been relatively unimpressive thus far
with practically no ascent present, and as a result, only a very
low potential for a couple showers exists. Have maintained some 10
PoPs through this evening across our eastern zones within the
area of better moisture. Otherwise, a warm and dry summer night is
expected with lows in the mid 70s to near 80 degrees.

.LONG TERM...
An upper level ridge will start to weaken on Tuesday but will
keep us hot and mostly rain-free through the day Tuesday. The
good news is that the weather across North and Central Texas will
be nice for viewing Monday`s solar eclipse with mostly sunny
skies expected area wide. There will be low chances of showers and
thunderstorms Monday afternoon east of a Bonham to Corsicana to
Temple line and on Tuesday afternoon southeast of a Temple to
Palestine line. Highs will be in the 90s both days with heat index
values in the upper 90s to 108 degrees.

As a shortwave moves down the Northern and Central Plains in the
northwesterly flow aloft, a cold front will slide down the Plains
on Tuesday. This front will approach the Red River Tuesday night.
Thunderstorms chances will spread southeastward during the
evening through the overnight hours. A few strong to severe
thunderstorms will be possible Tuesday night and some locally
heavy rain will also be possible.

We will have below seasonal normal highs for the rest of the week
thanks to the increased cloud cover and chances of showers and
thunderstorms. Highs will be in the mid 80s north to upper 90s
south Wednesday, mid 80s to lower 90s Thursday and Friday.
Some drier air looks like it will work its way in from the
northeast Thursday and Friday bringing lower rain chances to our
northeastern zones Thursday night and Friday. Another decent
shortwave is expected to approach late Saturday into Sunday
bringing better chances of showers and thunderstorms for next
Saturday night and Sunday.

.AVIATION... /Issued 131 PM CDT Sun Aug 20 2017/
VFR conditions and southerly winds in the 6 to 10 kt range will
continue to prevail for all the TAF sites through the forecast
period with scattered mid-to-high level clouds. The latest high
resolution model guidance shows some short lived isolated showers
developing across the Metroplex around 20-22Z, likely due to the
growth of cumulus clouds in areas where there is plenty of
moisture. However, the potential for showers to develop is too low
for it to be mentioned in the TAF.

For tomorrow morning, MVFR stratus will likely develop in the
Hill Country, but it is not expected to reach the KACT TAF site.
