.SHORT TERM...(Tonight through Monday night)
Issued at 246 PM CDT Sun Jun 10 2018

Most of the area is dry and quite hot and humid. Boundary was from
near KFWC to KEHR, with strong to severe convection up across
central IL moving southeast. Convection continues across the KY
Pennyrile area as well. Airmass very unstable. However ML CIN just
now eroded. Best storm chances will be across north and east
sections (EVV Tristate, southern IL), with little if any chance
west into southeast MO through the evening hours. Storms could
once again produce severe downbursts and marginally severe hail.
Very heavy rainfall in a short amount of time is likely with
stronger storms. Evolution is still somewhat uncertain. The trend
is our friend, based on Sat and Radar, as CAM's continue to be
borderline useless, depending on which one you pick from the last
24 hours. Convection should taper off overnight. Lull Monday as
well, though small chances exist SEMO and the KEVV Tri-state.
Marginal day two is awful big. But any storms that do form could
produce strong wind gusts and marginally severe hail. Small
chances continue EVV Tristate Monday night.

.LONG TERM...(Tuesday through Sunday)
Issued at 246 PM CDT Sun Jun 10 2018

Models continue to have a front that will shift back and forth
across the region through the extended forecast.  GFS and ECMWF show
the front north of the PAH forecast area at 12z Tuesday, then along
the Ohio River into northern Arkansas by 18z Wednesday.  Models
indicate the front will eventually shift just north of our area by
Friday, but then drop back southwest for the weekend.  This
basically keeps us in an unstable weather pattern, with on and off
shower and thunderstorm chances.  The best chances will be the
daytime hours into the early evening, but kept overnight low chances
going in areas close to where the front is expected to be located.

It will remain hot and humid through the period.  Predominantly
south winds will continue to pump warm moist air into the middle
Mississippi and lower Ohio valleys.  Though the front may dip far
enough south to shift our winds to the north in our northern half of
counties at times, the air mass north of the front will only be a
degree or two cooler and less humid.  Highs will generally be around
90 degrees, with lows of 69 to 73 degrees.  Dew points will remain
around 70 degrees to the lower 70s, which will push afternoon heat
indices to around 100 degrees in some locations.

.AVIATION...
Issued at 1215 PM CDT Sun Jun 10 2018

VFR conditions save for areas of convection through this evening.
Best chances will be east of the MS River. Will have a VC mention
at KEVV and KOWB for later this afternoon and evening. SSW winds
will gust 15 to 20 kts at times til sunset. Behind morning
convection over SE IL, SW IN, SE winds behind outflow will
eventually become SSW.
