.SHORT TERM...(Today through Tuesday night)
Issued at 333 AM CDT Sun Aug 22 2021

In the very near term, visibilities have dropped to a half mile or
less in portions of southeast Illinois, southwest Indiana and
northwest Kentucky. Will be issuing a dense fog advisory for
these locations.

Models show a mid/upper level high centered over the Arklatex
region today into the early part of the work week, with broad
ridging extending into the upper Mississippi valley and Great
Lakes region. At the surface, models show a weak cold front
sinking south of the PAH forecast this morning. Light northerly
winds behind the front will help keep high temperatures today
near seasonal readings in the 87-91 degree range, but
unfortunately will not bring down our dew points more than a
degree or two. An isolated shower or storm is not completely out
of the question today, but the upper level ridge is most likely
going to tamp down any convection and will go with a dry forecast
for now.

The front will lift back north tonight and wash out as surface
high pressure settles east of our region. Winds will shift back to
the south, and this will bring hotter and more humid air to the
middle Mississippi and lower Ohio valleys. High temperatures
Monday will reach the lower 90s, and the middle 90s Tuesday, and
dew points will climb into the lower to middle 70s. Afternoon heat
indices will reach 100 to 105 degrees Monday, and potentially
around 105 degrees on Tuesday.

.LONG TERM...(Wednesday through Saturday)
Issued at 333 AM CDT Sun Aug 22 2021

As we head into midweek, we will remain on the eastern side of an
upper level high. Seeing the trends in the forecast for the first
part of the week, causes some pause on letting the forecast go
totally dry on Wednesday, given the prospects of energy riding
around the eastern side of this upper ridge. Currently have some
slight chance PoPs in place for Wednesday into Wednesday night in
our northeastern sections, which will be near the ring of possible
fire on the edge of the upper ridge. The latest operational models
do hint at convection diving south across the area mainly Wednesday
night across our northeastern to eastern counties. Something to keep
an eye on to possibly raise PoPs if we see some consistency and
confidence increases. The main issue will be the continued heat,
with highs continuing in the lower to mid 90s with heat index values
generally in the 100 to 105 degree range.

As we head into Thursday and Friday, PoPs will go up a bit due to
the increase in moisture from the southeast, as an upper level
system develops in the Gulf Coast area and moves westward with time.
This southeasterly fetch of moisture even continues into the first
part of the weekend. In addition, the upper high begins to break
down by the weekend. This moisture combined with possible surface
troughs developing in the area along with upper level energy, could
yield some scattered convection for the latter part of the week and
into the weekend.

The good thing is, we should see an increase in cloud cover and with
the rain prospects going up a bit, temperatures should not be as
blazing hot and will drop a few degrees each day starting on
Thursday, which will still be in the low 90s. However, heading into
Friday and the weekend, highs should drop back down into the upper
80s to near 90 degrees.

.AVIATION...
Issued at 1205 PM CDT Sun Aug 22 2021

Pesky MVFR cigs have been reluctant to scatter out today, but
expecting bases to rise into low VFR territory nearly everywhere
by 19-20z. Skies clear out this evening and winds go calm, setting
the stage for some IFR/MVFR fog development overnight into the
early morning. As the fog dissipates, winds become light southwest
tomorrow morning.
