DSAWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, 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 this severe thunderstorm warning went out at Aug 15, 3:05 PM CDT, 1 hour 2 minutes earlier.
Area forecast discussion, Aug 15, 3:05 PM CDT, 1 hour 2 minutes before
Area Forecast Discussion National Weather Service Springfield MO 305 PM CDT Sat Aug 15 2020 .SHORT TERM...(This evening through Sunday) Issued at 242 PM CDT Sat Aug 15 2020 Expecting isolated to perhaps scattered convection near the Arkansas/Missouri border and in the far southwest CWA (far southeast Kansas and far SW Missouri). The convection is in response to an outflow boundary moving S-SW across the area and a cold front currently along the northern CWA border that will continue to move south. Current surface based CAPE is analyzed to be 4,500-5,500 J/kg and shear is very limited ahead of the boundaries. Limited moisture along with the weak shear will keep storms isolated and short lived, but with the instability in place we could see some brief strong to severe storms. Convection will diminish this evening, leaving a pleasant night and day Sunday. Lows tonight will be in the low to mid 60s with Sunday seeing sunny skies and highs in the mid 80s. Not only will Sunday be cooler, but also drier with dew points 15-20 degrees lower than today. .LONG TERM...(Sunday Night through Saturday) Issued at 242 PM CDT Sat Aug 15 2020 Not carrying any precip chances through this period and not seeing any chances for significant precip through the week. High temperatures will be warmest on Monday in the mid 80s to lower 90s, then in the mid to upper 80s the rest of the week. Afternoon dew points will be in the mid 50s to low 60s through the period, making conditions even more comfortable under mostly clear skies. Overnight low temperatures will be in the upper 50s to mid 60s. && .AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon) Issued at 1240 PM CDT Sat Aug 15 2020 A cold front moving through will switch winds to a northerly direction and bring chances for showers and storms later this afternoon and evening. Greatest chances for storms are at KJLN, with chances being too limited elsewhere to include in the forecast at this time. Otherwise, VFR conditions are expected. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. && SHORT TERM...Titus LONG TERM...Titus AVIATION...Titus
