Numerous outflow boundaries and weakening storms remained over the
region after 6 pm this evening. These storms will continue to
weaken and dissipate as the sun sets and day time heating is lost.
High pressure will continue to influence the regions weather
through the overnight hours with cloud cover diminishing, allowing
for mostly clear skies and temperatures falling into the lower
.SHORT TERM...(This Evening through Wednesday)
Temperatures were approaching 100 degrees once again in several
areas of southern Missouri and southeast Kansas. The summertime
high is firmly in control of the Ozarks weather.
A weak area of convergence was analyzed along the Interstate 44
corridor this afternoon, helping to trigger a few thunderstorms
from Rolla over toward Avila.
We suspect these updrafts will continue to develop in isolated to
scattered fashion the rest of the afternoon, eventually
dissipating around sunset.
We decided to extend the Heat Advisory through Wednesday
afternoon. Temperatures could certainly be a little cooler
tomorrow, however, dew points are not expected to mix down as
much, keeping the Ozarks airmass feeling humid. Therefore we
expect heat indices to range from 98 - 104 degrees Wednesday
Other than a few isolated thunderstorms Wednesday, nearly all
locations should remain dry. The better chances for rain should
occur near a frontal system stretched across central Missouri.
.LONG TERM...(Wednesday Night through Tuesday)
Regarding this Heat Advisory, we`ll take it one day at a time. The
summertime high gradually breaks down in the mid levels Thursday
and Friday. But how this translates into cooler temperatures is
still unknown...specifically for Thursday. It`s quite possible an
extension of the advisory may be needed into Thursday, but we`ll
assess that tonight and again tomorrow.
By Friday, cloud cover is expected to spread over the Ozarks from
the southwest, in advance of an approaching upper level low
Eventually rain will follow, most likely Friday night and through
Saturday. The holiday campers, boaters, and floaters should
monitor radar trends prior to hitting the water, in case
thunderstorms are rolling in. In fact, anyone participating in
Labor Day Weekend outdoor festivities should remain abreast of
thunderstorms risks. The great thing about Saturday and Sunday,
temperatures will be cooler, with highs only in the 80s.
As of now, Labor Day (next Monday), looks ideal for outdoor
activities, with temperatures potentially warming back toward the
upper 80s or 90.
