The episode as NWS SGF wrote it up.
An upper level disturbance interacted with moisture overriding a stalled front over Arkansas to produce showers and a few thunderstorms over the area from the afternoon of the 7th to the early morning of the 8th. While most of the area received between one-quarter to one-half inch of rain, locations along Interstate 44 from Joplin to Springfield and along Highway 60 from Springfield to Cabool received over one and a half inches. Isolated reports of flooding were received from Lawrence, Douglas and Wright counties where soils were already saturated from heavy rain earlier in the month.
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 Mar 8, 5:06 AM CST, 38 minutes earlier.
Area Forecast Discussion National Weather Service Springfield MO 506 AM CST Wed Mar 8 2023 Key Messages: 1. Several rounds of rainfall from currently through Sunday. 2. Cooler than normal temperatures through the seven day forecast period. 3. Low end chances(<30%) of excessive rainfall with these rain events. .SHORT TERM...(Today and tonight) Issued at 210 AM CST Wed Mar 8 2023 A solid band of light to moderate rainfall was working its way eastward across the forecast area early this morning with the leading edge pushing into south central MO and the back edge from near Joplin to the Lake of the Ozarks. Upper level energy embedded in a broad area of southwest flow aloft was interacting with a low level moisture surge from the southwest into the area to produce the rainfall. HREF members are in decent agreement in shifting the main area of precipitation eastward and then south of the area this morning, but there also appears to be a good signal for some stratus and drizzle behind the main area of rain. Will maintain some drizzle chances through midday in an area of 10% pops behind the main rainfall. Temperatures were in the low to mid 40s across the area early this morning and will not see much of a temperature rise today with the expected cloud cover. Highs are expected to reach the mid to upper 40s in the east and the upper 40s to mid 50s in the west. HREF probabilistic data show main area of rain ending this morning with the drizzle potential continuing into midday. Tonight, additional shortwave energy will begin to shift into the area along with another surge of low level moisture. Rainfall is expected to spread from southwest to northeast during the night and into Thursday. Lows will range from the upper 30s in the east to the mid 40s in the west. .LONG TERM...(Thursday through Tuesday) Issued at 210 AM CST Wed Mar 8 2023 The main shortwave energy will shift eastward from the plains into the Mississippi valley on Thursday but remain north of the forecast area. Rain is expected over the area for much of the day and into the evening before ending as a cold front moves through the area. With the rainfall ongoing into this morning, will have to monitor this second system for some minor flooding, but the heaviest rain chances look to be both south and north of the forecast area. North with the better lifting associated with the shortwave and south with the better moisture. The better chances for flooding will exist south of the area. The clouds/precipitation will keep temperatures generally in the 50s for most of the area on Thursday and dipping into the low to mid 30s for lows behind the front on Thursday night. A cooler and drier air mass will move in behind the front, with highs on Friday from the mid 40s in the north to the mid 50s in the south. Lows are expected to dip back down into the 30s Friday night. The upper flow remains active and more shortwave energy is expected to shift east into the area over the weekend with rain chances increasing again from Saturday into Sunday. It appears the colder air supporting snow chances will remain north of the area. For Monday into Tuesday, a much colder air mass will then move into the area behind the front on Sunday. We could see lows Monday night dip into the mid to upper 20s with highs only in the 40s on Monday. && .AVIATION...(For the 12Z TAFS through 12Z Thursday morning) Issued at 505 AM CST Wed Mar 8 2023 For the 12z TAFS, stratus expected to continue today with mainly MVFR conditions. Will probably see some IFR as we head into the evening and overnight with the next wave of moisture and rain moving into the area. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE.
