The episode as NWS SGF wrote it up.
An isolated thunderstorm produced hail up to quarters in size.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Springfield, MO wrote its last area forecast discussion before the first event at Apr 9, 1:16 PM CST, 2 hours 43 minutes earlier.
Area Forecast Discussion National Weather Service Springfield MO 216 PM CDT Fri Apr 9 2021 .SHORT TERM...(Tonight through Saturday) Issued at 216 PM CDT Fri Apr 9 2021 Warm front location remains a bit uncertain given variable winds and mixing of dew points that had surged earlier in the day...though attention is with band of convection moving northward over northwest Arkansas. Convective models tend to wash out this initial activity and reform it in a west to east band over southwest Missouri between 1930 and 21z. Temperatures that have warmed into the upper 70s to low 80s have helped CAPES climb to around 1500...combined with bulk shears around 40 to be enough for a window of organized convection with this initial round of convection. Hail to the size of golf balls along with winds to 60 mph are the primary threats. Good confidence then for discrete cells to form ahead of a complex boundary system over Oklahoma to grow into a line of storms that will propagate eastward into Arkansas later this evening. Far southwest Missouri will find itself on the northern end of this second area of potential damaging wind threat with instability and threats diminishing along the frontal boundary as it extends northeast out of Oklahoma to eventual lay roughly along I-44. The combination of thunderstorm clusters will lead to 0.75 to 1.75 QPF making isolated flooding also a possibility. Showers with embedded non severe thunderstorms to be found farther north this evening to extend forecast area wide overnight as an upper low approaches Joplin toward 12z. May see an uptick in convection as the upper low approaches late tonight but additional severe storms are not expected. Cool and wet conditions are then expected on Saturday as cold advection on the back side of the low results in lingering light rain/drizzle throughout much of Saturday. .LONG TERM...(Sunday through Friday) Issued at 216 PM CDT Fri Apr 9 2021 Just as quick as they fell on Saturday...heights will rebound on Sunday as the upper low departs eastward and ridging develops ahead of the next wave. Temperatures as a result will warm back into the 70s. The passage of a cold front though Sunday night will continue the temperature roller coaster that will see high temperatures on Monday back in the 60s and the potential for some patchy light rain. The seasonal cool weather will then remain through the end of the work week as waves in the northern stream periodically cross the Plains. While outside the forecast period the amplification of the upper ridge over the West Coast signals the approach of the anticipated well below temperatures next week. && .AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon) Issued at 1247 CDT Fri Apr 9 2021 Thunderstorms to form into two predominate areas early in the forecast period. First convection will be scattered in nature along a warm front lifting northward over southern Missouri during the mid afternoon hours followed by a line of storms moving west to east this evening. Some of these storms may be severe over southwest Missouri from I-44 southward into Arkansas. Otherwise...MVFR will give way to IFR overnight as lower levels in the atmosphere cool and saturate leading to widespread light rain and drizzle into Saturday morning. && .SGF WATCHES/WARNINGS/ADVISORIES...
