.AVIATION...

Upper level high pressure continues to dominate. Convection
continues to wane with the loss of daytime heating and will
dissipate completely over the next few hours. Convection will
develop once again Thursday afternoon but remain isolated in
nature and VCTS will suffice. Widespread VFR conditions are
expected except for brief MVFR conditions around sunrise due to
fog. Light south to southeast winds will continue.

.PREV DISCUSSION...(ISSUED 257 PM CDT WED JUL 20 2016)

SHORT TERM...Tonight Through Thursday Night
A large area of high pressure aloft continues to be centered over
Oklahoma. No movement of this high is noted in the models through
Thursday. The pattern will continue with hot and humid conditions
with a slight chance of afternoon showers and thunderstorms. Many
areas will see heat indices at or above 105 degrees Thursday and
actually Friday. Therefore we have extended the Heat Advisory
through Friday afternoon. High temperatures will be mainly in the
mid and upper 90s.

LONG TERM...Friday Through Wednesday Night
The large and flattened upper level ridge that has been across the
area will persist through the weekend, but by Monday things will
start to change just a bit. The ridge will become more pronounced
over the east and west coasts, leaving a weakness and a bit of
troughing across the central part of the country, which should
enhance chances for afternoon convection. In addition, any
nocturnal MCS development that occurs over the plains will be more
likely to drift into our forecast area during the early AM hours.
