.SHORT TERM...(Tonight through Friday night)
Issued at 239 PM CDT Wed Apr 29 2020

This morning's destructive sunshine in southeast Missouri has led
to scattered showers and a few thunderstorms developing, with the
greatest coverage stretching from the MO Bootheel through the KY
Purchase and into SE Illinois and SW Indiana. The greatest chance
of thunder this afternoon will be in the corridor of highest
lapse rates and surface-based CAPE, covering the MO Bootheel into
western KY and far southern IL. Tonight, we'll lose shower and
thunderstorm coverage with the loss of diurnal heating after 0z
Thursday. Gusty post-frontal west-northwesterly winds of 20-25
kts will gradually relax this evening.

With another weak trough progged to rotate around the back of the
departing upper low, have maintained slight to low chances POPs
through much of Thursday in the Evansville Tri-State, West KY
Coalfields, and southern KY Pennyrile. This trough will lead to a
stark gradient in sky coverage tonight through Thursday, with
mostly clear skies in the Ozark Foothills to mostly cloudy in the
Evansville Tri-State and KY Pennyrile. After, 0z Friday, dry
conditions are expected areawide through Friday night as upper-
level ridging takes hold.

Temperatures will not cool much behind the cold front tomorrow,
with highs generally in the low to middle 60s. A warming trend
will begin Friday, with high temperatures warming into the upper
60s to lower 70s. Overnight lows will fall into the 40s both
tonight and Thursday night.

.LONG TERM...(Saturday through Wednesday)
Issued at 239 PM CDT Wed Apr 29 2020

The long term begins with the above normal temperatures from the
Desert Southwest having spread into/across the southern Plains, into
the South. These 10-20F above normal readings will be closer to the
low end of that threshold here, as that airmass modifies, but it
will still mean some 80F readings popping up for weekend highs.

The weekend will start out dry, but as the transitioning to zonal
flow pattern works the warm air in, so too does it lead to some
incoming energy pushing a front into our neck of the woods by
Sunday. Moisture increasing/pooling along this boundary, combined
with daytime heating/instability, spells our next best chance of
storms Sunday pm. The 12Z deterministic runs of the GFS/ECMWF both
show PW's increasing to about 1.6" by 00Z Monday, near the 99th
percentile. The NAEFS confirms, pinging Q/PW standard deviations
approaching 2. And while deep layer shear will increase some as well
during this time frame, sounding numbers are not so impressive just
yet to warrant inclusion on the SPC outlook.

The latter half of the long range is where lower confidence enters
the forecast thinking, with regard to specificities of the relative
dry wx lull Monday, in between the departing Sunday and then
reintroducing Tuesday-Wednesday pops. The GFS appears overly
aggressive with in between pcpn generation, while the ECMWF is on
the other end. The blend straddles the median, painting low pops
thru the entire frame. The collaborative approach has been and
appears to continue to be going dry the latter half of Monday, with
relative small pops immediately before and after (morning/evening).
We see no new data argument to deviate from that approach.

The Tuesday-Wednesday return pops of the NBM are accepted, with
thunder chances primarily during the PM hours Tuesday. The
additional pops/clouds means mid week temps will mute closer to/if
not slightly still just above seasonal norms.

.AVIATION...
Issued at 1225 PM CDT Wed Apr 29 2020

With the upper-level low overhead, widespread CU along with
scattered showers and isolated thunderstorms are developing over
southern Illinois, southeast Missouri, and far western Kentucky
early this afternoon. With the steepest lapse rates over southeast
Missouri and the KY Purchase, added a mention of VCTS through 00
UTC Thursday at KCGI and KPAH. Elsewhere, have maintained VCSH.
At KEVV/KOWB, isolated showers will be possible throughout the
night.

Cigs will deteriorate to MVFR tonight as low stratus continues to
wrap behind the departing upper low. Cigs will improve after 12z
Thursday. Winds will be generally west-northwest at 10-15 kts with
gusts to 20-23 kts at times.

...Gusty Thunderstorms With Small Hail and Cold Air Funnel Clouds
This Afternoon...

Through late this afternoon, thunderstorms capable of producing
gusty winds of 40 to possibly as high as 50 mph, pea size hail,
and cold air funnel clouds are possible. Cold air funnel clouds
rarely touch the ground. If they do reach the ground, they
typically produce minimal damage for a brief amount of time.
