1142 PM CDT Tue Jul 18 2017

.SHORT TERM...(This evening through Wednesday)
Issued at 250 PM CDT Tue Jul 18 2017

An upper level ridge of high pressure will continue to build over
the region. This will keep conditions dry with a slight uptick in
temperatures. Highs on Wednesday should be a degree or so warmer
than what we see this afternoon. This will put heat indices in the
97 to 105 degree range with the warmest readings extending from
the I-49 corridor into central Missouri. Slightly drier dew points
(due to mixing effects) will keep heat indices slightly cooler
elsewhere across the Ozarks.

.LONG TERM...(Wednesday Night through Tuesday)
Issued at 250 PM CDT Tue Jul 18 2017

The summertime ridge will continue to expand over the region to
end the week. This will result in even warmer temperatures with
most places warming into the middle to upper 90s from Thursday
through Saturday. Confidence is now high that much of the Missouri
Ozarks and southeastern Kansas will see at least four consecutive
days of heat indices around or slightly above 100 degrees
(Wednesday through Saturday). Thus, we have issued a Heat Advisory
for much of the area. The Excessive Heat Warning was left intact
over portions of central Missouri. Heat indices over that area
will be closer to 105 degrees for four consecutive days.

Global models begin to flatten and suppress the ridge as we get
into Sunday and early next week. This should result in some
chances for thunderstorm activity along with slightly cooler
temperatures. It is possible that heat headlines may need to be
extended into Sunday depending on how quickly that ridge flattens
along with the coverage of thunderstorms.
