Area Forecast Discussion
National Weather Service Springfield MO
637 PM CDT Wed Jul 19 2017

.SHORT TERM...(This evening through Thursday)
Issued at 224 PM CDT Wed Jul 19 2017

An upper level ridge of high pressure will continue to build over
the region through Thursday. With a slight increase in partial
thicknesses expected between now and Thursday, we should add
another degree or two to high temperatures. This will put almost
all of the Missouri Ozarks solidly into the middle and upper 90s.

No precipitation is expected through Thursday due to subsidence
beneath the ridge.

.LONG TERM...(Thursday Night through Wednesday)
Issued at 224 PM CDT Wed Jul 19 2017

That ridge will keep a firm grip on the region through Saturday.
Thus, hot and humid conditions will continue with virtually no
chances for precipitation through the daytime hours on Saturday.

We did make some changes to the heat headlines across the region.
Given that areas along the I-49 corridor saw 105+ heat indices
today, we have now become confident that this area will see
similar heat indices for at least four consecutive days (through
Saturday). We have therefore upgraded the I-49 corridor and
portions of the Highway 54 corridor to an Excessive Heat Warning.
The Heat Advisory remains in effect across the remainder of the
Missouri Ozarks through Saturday.

By Sunday, models continue to indicate that the ridge will finally
begin to flatten as upper level energy dives southeast across the
Great Lakes. This should give us some opportunities for
thunderstorms from Sunday into the middle of next week.
Temperatures will also be a bit cooler as a frontal boundary
slides south into the region.
