Updated for 00Z aviation forecast discussion,.

.SHORT TERM...(Tonight through Wednesday night)
Issued at 305 PM CDT Mon May 9 2016

Southerly winds through the short term period will bring an ever
more humid air mass across the region. This will help to fuel
periods of convection as a series of upper-level disturbances move
through the region. There currently are 3 periods of concern for
strong to severe thunderstorms. The first will be tonight, the
second will be Tuesday afternoon/evening, and the third will be
Wednesday night.

A weak disturbance that is currently pushing some light rain through
western portions of southeast Missouri will lift northeast with
showers skirting along the northwest periphery of the area this
afternoon. A lack of destabilization today should prevent any
thunderstorms with this activity.

A stronger upper-level disturbance will push northeast into the
area tonight. This disturbance will likely touch off strong to
severe thunderstorms over Arkansas later this afternoon, and
these storms should eventually attempt to push into at least
southeast Missouri. Given the lack of destabilization over our
area, we would expect these storms to be weakening and pose mainly
a locally heavy rain/lightning threat. However, it is likely that
these storms will be organized into one or more linear clusters,
which may maintain a damaging wind threat into our region. Figure
the severe threat will be confined to southeast Missouri and
southern Illinois this evening. Widespread showers and
thunderstorms are expected to push eastward through the entire
region overnight, but Tuesday should start out dry for much of the
region.

By midday Tuesday, a much stronger upper-level trough will be
moving eastward just to the north of the region, resulting in
strong westerly flow aloft over the four state area. This should
prime the environment for our best shot of severe weather through
the afternoon. However, as was the case today, destabilization may
be difficult to achieve, so this is by no measure a slam dunk
severe weather event. Think that SPC's Slight Risk looks good for
Day 2.

After Tuesday's system pushes east of the area, we should dry out
for much of Tuesday night and possibly Wednesday, as short-wave
ridging passes through the region. The base of a larger-scale
trough is forecast to push into the region Wednesday night, and
severe weather is likely to our west/northwest during the day. The
flow aloft over our region is quite weak through Wednesday
evening, so we could see a strong to severe storm/cluster try to
maintain strength into southeast Missouri and southern Illinois
in the evening, but this activity would generally be weakening as
it moves deeper into the area.

.LONG TERM...(Thursday through Sunday)
Issued at 331 PM CDT Mon May 9 2016

The medium range models and their ensemble means were in reasonable
agreement in depictions of the mid/upper pattern over the CONUS.

The extended period will start out with waning probabilities of
showers and tstms Thursday and Thursday night as a cold front,
driven by northern stream shortwave energy, sweeps through the PAH
forecast area. The pcpn will be replaced by high pressure at the
surface Friday as the mid/upper flow switches to a more
northwesterly direction. In this west northwesterly flow aloft, a
reinforcing surge of cool air is expected to arrive in our region
early Saturday, with most of the measurable rainfall occurring
Friday night. There could be a sprinkle or two Saturday morning if
there's any deeper moisture left, along with cooler than average
temperatures.

For the latter half of the weekend, a baroclinic zone (and focus for
shower and tstm development) is progged to set up in or near the PAH
forecast area, between high surface pressure to the north and low
surface pressure developing in the southern Plains. Though the
smaller details of the deterministic models are more murky at this
time frame, it appears that shower and tstm chances will be fairly
decent across our region Sunday through Monday, as indicated by the
initialization blend. Warm advection should help boost temperatures
back to near seasonable by Monday (Day 7).

.AVIATION...
Issued at 620 PM CDT Mon May 9 2016

Lots of mid clouds over the area today along with scattered
rain showers this afternoon. Some MVFR ceilings will gradually
spread east across southeast MO this evening and the rest of the
region tonight. There is some evidence for IFR ceilings as well
with time. The convective forecast continues to be seriously
muddled due to a lack of instability. The forecasts represent our
best guess at this time, but confidence is not great.

Another potential round convection is expected to develop over the
region by midday Tuesday and move east through the entire area
through the afternoon. For now, tried to highlight best chance for
storms early on this evening, but left VCSH or VCTS for the
remainder of the forecast. There will be dry periods however.
Winds will remain southerly and gusty at times.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF SOUTHERN
ILLINOIS...SOUTHWEST INDIANA...WESTERN KENTUCKY AND SOUTHEAST
MISSOURI.

.DAY ONE...THIS AFTERNOON AND TONIGHT

THUNDERSTORMS WILL PUSH NORTHEAST INTO AND THROUGH THE FOUR STATE
REGION FROM MID-EVENING THROUGH THE OVERNIGHT HOURS. A FEW STORMS
MAY PRODUCE DAMAGING WINDS MAINLY OVER SOUTHEAST MISSOURI AND WEST
KENTUCKY. OTHERWISE...LOCALLY HEAVY RAINFALL AND LIGHTNING WILL
BE THE PRIMARY CONCERNS.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

SCATTERED TO NUMEROUS THUNDERSTORMS ARE EXPECTED TO DEVELOP OVER
THE REGION AROUND MIDDAY TUESDAY AND THEN PUSH EASTWARD THROUGH
ENTIRE REGION IN THE AFTERNOON. SEVERE STORMS WITH LARGE HAIL AND
DAMAGING WINDS WILL BE POSSIBLE...ALONG WITH LOCALLY HEAVY
RAINFALL AND LIGHTNING. THE AMOUNT OF INSTABILITY THAT CAN DEVELOP
DURING THE DAY IS IN QUESTION AND WILL BE THE LIMITING FACTOR FOR
SEVERE WEATHER TUESDAY.

ISOLATED TO SCATTERED THUNDERSTORMS WILL BE POSSIBLE TUESDAY NIGHT
AND WEDNESDAY...BUT SEVERE STORMS ARE NOT EXPECTED. THUNDERSTORMS
ARE FORECAST TO PUSH THROUGH THE ENTIRE AREA WEDNESDAY NIGHT. A
FEW STRONG TO SEVERE STORMS MAY REACH SOUTHEAST MISSOURI AND
SOUTHERN ILLINOIS WEDNESDAY EVENING BEFORE WEAKENING. DAMAGING
WINDS AND LARGE HAIL WILL BE THE PRIMARY CONCERNS.

SMALL CHANCES OF THUNDERSTORMS ARE FORECAST OFF AND ON FROM
THURSDAY THROUGH SUNDAY. ANY THUNDERSTORMS IN THIS PERIOD WILL
REMAIN BELOW SEVERE LEVELS.

.SPOTTER INFORMATION STATEMENT...

SPOTTERS SHOULD BE PREPARED FOR POSSIBLE ACTIVATION LATE THIS
EVENING AND OVERNIGHT...AND AGAIN TUESDAY AFTERNOON AND EVENING.
