Area Forecast Discussion
National Weather Service Springfield MO
232 PM CDT Tue Aug 2 2022

Key Messages:

1. Heat Advisory continues through Wednesday. Heat Index around
100-105+ degrees.

2. A few isolated thunderstorms this afternoon east of Highway
65.

3. Elevated Fire Weather potential on Wednesday.

4. Showers and thunderstorms likely Wednesday Evening-Thursday
Morning.

5. Excessive heat continues through the weekend.

.SHORT TERM...(This evening through Thursday)
Issued at 230 PM CDT Tue Aug 2 2022

Through Tonight: Latest visible satellite imagery depicts a
deepening cumulus field across southern and central Missouri this
afternoon. A few isolated showers and thunderstorms have developed
across this area. Recent analysis of the mesoscale environment
shows MLCAPE values of 2000 to 3000 J/kg in the presence of a
moist airmass (PWAT values around 1.7 inches). However, forcing
remains limited across the area. Expectations are for coverage to
remain sparse and limited to areas east of the Highway 65
corridor. Otherwise, most locations will remain hot and dry
through the evening. Overnight lows fall into the 70s areawide
with dry weather expected.

Wednesday: Changes are on the horizon heading into Wednesday as a
shortwave drops south through the region. This will result in an
increase in precipitation chances. Ahead of the system, another
hot and humid day is expected across the area. The hottest day of
the week could come on Wednesday as ensemble guidance suggests
850mb temperatures reaching around 24-26 C. Expect afternoon
highs to reach into the upper 90s to around 100 in many locations.
Afternoon heat indicies will approach 100-108.

An additional concern is the dry/hot conditions and fire weather
potential on Wednesday. A combination of wind gusts of 25-30 mph
and relative humidity values as low as 35% may result in the rapid
spread of fires. This will need to be monitored across portions of
southeast Kansas and southwest Missouri.

The attention turns to Wednesday evening as clouds and
precipitation build into the region. Strong forcing ahead of a
shortwave will allow convection to develop across central Missouri
as early as Wednesday evening. The environment may be conducive
for a couple strong to severe thunderstorms across central
Missouri given the large amounts of forecast instability. It
should be noted that most of the activity will remain sub-severe,
with the best chances and SPC marginal severe weather outlook
along and north of the Highway 54 corridor. Damaging wind gusts
will be primary risk in the strongest thunderstorms. Coverage in
showers and thunderstorms will increase late Wednesday into the
overnight hours. Most locations will receive a 0.50 inch or less.
However, convective elements and training thunderstorms could aid
in the potential for highly localized rainfall amounts of 1-2
inches. The highest rainfall totals will likely occur across
portions of central and south central Missouri. A widespread
excessive rainfall is not expected at this time.

Thursday: Scattered showers and thunderstorms linger into Thursday
morning before dissipating to the southeast in the afternoon.
Precipitation and clouds slowly clearing the region will give way
to high temperatures likely in the lower 90s.

.LONG TERM...(Friday through Tuesday)
Issued at 230 PM CDT Tue Aug 2 2022

Friday-Sunday: Hot and humid conditions are likely to return this
weekend. Expect daily highs in the middle to upper 90s, with
afternoon heat indicies of 100-105. This will keep the area
running anywhere from 5-10 degrees above normal for early August.
Additional heat headlines may be needed through the weekend.

Precipitation chances look to remain low (20% or less) through the
weekend. Most locations will remain dry.

Next Week: Looking ahead to next week, dry and hot weather look to
continue. Likewise, minimal rainfall chances are in the forecast.
The combination of dry and hot conditions will allow the drought
to persist.
