Area Forecast Discussion
National Weather Service Springfield MO
628 AM CDT Tue Jul 18 2017

.SHORT TERM...(Today and tonight)
Issued at 334 AM CDT Tue Jul 18 2017

Another seasonably hot and humid day is in store as high pressure
at the surface and aloft become entrenched across the region.
Highs today will climb into the middle 90s at most locations while
afternoon heat index values generally range in the upper 90s to
near 100. No heat headlines issued for today.

.LONG TERM...(Wednesday through Monday)
Issued at 334 AM CDT Tue Jul 18 2017

A prolonged hot spell will impact the region from mid week into
the weekend as the upper level ridge remains the dominant weather
factor. High temperatures will climb into the mid and upper 90s on
a daily basis and may approach the 100 degree mark across central
Missouri. A humid airmass will remain in place but the degree of
low level mixing and lowering afternoon dewpoints is a question
that will impact heat index values. Generally expect heat index
values to range from the upper 90s to around 105 on a daily basis
with the highest readings across central Missouri.

Went ahead and upgraded the existing Excessive Heat Watch to
warning across portions of central Missouri beginning Wednesday
through Saturday. Heat Advisories will likely need to be issued
for portions of southern Missouri and southeastern Kansas.

The upper ridge may break down abit later this weekend or early
next week allowing for minor cooling. This may also allow a weak
frontal boundary to sag southward into the region Sunday or Monday
resulting in a low chance for showers and storms.
