.DISCUSSION...
Issued at 219 AM CDT Tue Jun 18 2024

Little has changed in the forecast with hot and humid conditions
still expected the next several days. Stout ridging along with
surface high pressure is situated over the eastern US with troughing
over the west. We remain caught in the middle with ample warm air
advection and southerly flow thanks to the ridge to our west.
Temperatures are expected to rise to the low to mid 90s for another
day. Heat indices will top out in the mid to upper 90s. Like Monday,
winds will be breezy again with gusts up to 30 mph possible this
afternoon.

By the afternoon/evening, our attention will turn to a shortwave
trough shifting to the northeast through the northern High Plains.
This will send a frontal boundary toward our area along with
increasing shower and thunderstorm potential. Storm will develop
across Nebraska and Iowa and shift southeast into the evening,
eventually making it into far northern Missouri overnight. For the
most part, storms are expected to decrease in intensity as they move
toward our area, so widespread strong storms are not expected with
this system. As far as rainfall amounts, our far northwest will see
highest amounts with potential for as high as 2.5 inches. Shower and
thunderstorm activity may linger into Wednesday afternoon but will
gradually decrease over time. As the front moves through, highs will
vary greatly across the forecast area Wednesday with northwestern MO
only in the low to mid 90s with the remainder of the area still near
90 degrees.

For the rest of the week mainly dry conditions are currently
expected, however nearby shortwaves will decrease certainty. As far
as temperatures go, highs on Thursday will bounce right back to the
the upper 80s to low 90s. Temperatures are expected to be on a
warming trend for the later half of the week into the weekend with
mid 90s expected for Friday and Saturday. A better chance for
rainfall looks to hold off until Saturday night as a shortwave
slides north of the forecast area.
