...12z Aviation Forecast Update...

.SHORT TERM...(Today and tonight)
Issued at 236 AM CDT Sat May 26 2018

A leftover mid level impulse or "swirl" being seen on the
satellite imagery this morning near the Arkansas and Missouri
border. Radar still seeing some light showers over south central
Missouri. Where there was rainfall yesterday and where skies have
cleared out a bit, there is some patchy fog this morning. An
observation from one of the local weather cameras in Republic
showing some of that fog. That will burn off quickly shortly after
sunrise.

If you were needing some rain, hope you got some over the last few
days because rain chances will go away for a while. There could be
a couple spotty and isolated showers and storms pop up again later
today. The best chance for that will be over the eastern Ozarks
and south central Missouri. Otherwise, we are cranking up the
temperatures and the humidity as upper level ridging over the
Central U.S. builds slowly into our area.

.LONG TERM...(Sunday through Friday)
Issued at 236 AM CDT Sat May 26 2018

Sunday may be the hottest day so far this season and the heat is
just getting started. Highs will be in the lower 90s with heat
index values in the middle to upper 90s. We will be watching a
Tropical Storm Alberto`s track as it moves into the southern U.S.
by early next week. Usually around or west of tropical systems,
there is subsidence and warmer temperatures. This tropical system
may bring some additional high clouds and some tropical moisture
into the region starting late Monday into Tuesday. Models take the
core of the tropical moisture and low pressure up the Mississippi
Valley region with the majority of the rainfall just east of the
Ozarks. But it could skim portions of the far eastern Ozarks
middle of next week and something to keep an eye on. A weak
frontal boundary will also sag down on Wednesday and Thursday. It
interact with any of the leftover tropical moisture to give us a
good chance of showers and storms. That will also knock our
temperatures back into the middle and upper 80s for a couple days
middle of next week.

Medium to long range guidance shows a big summer time upper level
ridge building over the south central U.S. by the end of next
week through next weekend. That means big time heat may be coming
with highs easily approaching the middle 90s and heat index
values between 100 and 105 degrees by next weekend.
