...More Summer Heat and Humidity through Wednesday...

.SHORT TERM...(This evening through Tuesday)
Issued at 224 PM CDT Mon Jul 24 2017

A storm or two cannot be ruled across far southern Missouri and
eastern Ozarks through early this evening and again Tuesday
afternoon within a low level moisture axis. However the lack of
low level convergence and relatively dry mean moisture within the
700 to 300 MB layer will be limiting factors to convective
development.

Otherwise most if not all locations will remain dry through
Tuesday as the upper level ridge begins to expand back over the
region. High temperatures Tuesday will edge upward a degree or two
with maximum heat index values approaching 100 in some areas
particularly from southeastern Kansas into central Missouri.

.LONG TERM...(Tuesday Night through Monday)
Issued at 224 PM CDT Mon Jul 24 2017

The upper ridge will maintains it's grip on the area into
Wednesday allowing for highs to climb into the middle 90s. Heat
index values Wednesday will climb to between 100 and 105 degrees.
A Heat Advisory may eventually be needed for portions of the area
Wednesday.

A front sag southward into the region Thursday and Friday as an
upper level trough tracks across the Great Lakes region. This
front will be trigger for isolated to scattered showers and
thunderstorms. Organized severe weather is not anticipate but a
few stronger storms are possible given the moderate instability.

Dry and relatively cooler weather will follow this frontal
passage for the weekend with highs generally in the 80s to near 90
degrees.

.AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon)
Issued at 1151 AM CDT Mon Jul 24 2017

cumulus will impact the region this afternoon. Winds will be light
out of the north.
