.PREV DISCUSSION... /Issued 226 AM CDT FRI JUL 22 2016/

DISCUSSION...
The persistent heat and humidity will once again be the main story
today and tomorrow, with many locations likely to hit triple
digit high temperatures both afternoons. No changes will be made
to today`s Heat Advisory, which will remain in effect for the
entire forecast area from Noon to 9pm, and with similar heat index
values expected tomorrow, will issue another advisory areawide for
tomorrow with this forecast package. At least a portion of the
area will likely need an additional advisory for Sunday.

As was the case yesterday, afternoon convection should remain east
of the forecast area, but that should change for both tomorrow and
Sunday afternoons as the ridge overhead begins to shift slowly
westward. Eastern portions of the forecast area will be the focus
for the afternoon thunderstorms both days.

More widespread thunderstorm potential will arrive Monday and into
Tuesday as a cold front approaches from the north and passes
through the region. With the weakened upper level ridge positioned
in the western United States for much of next week, at least low
thunderstorm chances will persist even beyond Tuesday.
In addition to the increased rain chances, temperatures will be
cooler and closer to seasonal normals, especially through the
early to middle part of next week.
