SchaumannWhat 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 May 26, 3:33 AM CDT, 1 hour 57 minutes earlier.
Area forecast discussion, May 26, 3:33 AM CDT, 1 hour 57 minutes before
Area Forecast Discussion National Weather Service Springfield MO 333 AM CDT Fri May 26 2017 .SHORT TERM...(Today and tonight) Issued at 231 AM CDT Fri May 26 2017 Surface low pressure across the plains and an upper level short wave were acting to shift the upper ridge that was over the region yesterday to the east of the Ozarks. The surface low however, is expected by the models to make little to no progress to the east through today, keeping the Ozarks and southeastern Kansas in the warm sector south of the warm front now across northern Missouri. A few storms over northeastern Kansas early this morning were moving to the east. Mesoscale and short range models were not handling this well at all this morning. The GFS did show some depiction of the storms, but will need to see if they can hold together with the current hostile environment over the Ozarks region. The southerly flow will help bring more moisture from the Gulf into the region through the day today. A strong capping inversion noted on last evening's sounding and continued by the forecast soundings through tonight should keep storms from forming through today and through tonight. If a storm or two do develop, they will be elevated in nature with large hail the primary concern. .LONG TERM...(Saturday through Thursday) Issued at 231 AM CDT Fri May 26 2017 Today's surface low is expected to wash out leaving a stationary/warm front across central Missouri as lee cyclogenesis occurs and another surface low develops over eastern Colorado early Saturday morning. Deep southerly to southwesterly flow will continue to pump moisture into the region through early Saturday as the surface low moves across the plains. A strong low level jet will begin to impinge on the region as several short wave troughs move through the upper level southwesterly flow and across the Ozarks. Forecast soundings have been consistent in showing a very unstable airmass in place across the region Saturday afternoon and evening with 3800 to 4500 J/kg of ML CAPE. Increasing low level convergence and a weakening cap will act to kick off thunderstorms Saturday afternoon and continue into the evening. Indications and sounding analogs have shown a consistent signal for large hail to the size of baseballs and a damaging wind signal. Much of this will depend on the mode the storms ultimately take. More wind damage with bowing segments verses large hail with more clusters or individual supercells. This will be more of a mesoscale forecast issue to watch Saturday. The system looks to move through the region by Sunday morning to early Sunday afternoon depending of your model of choice. Either way, this will lead to the potential for lingering thunderstorms. Overall, the end of the Memorial Day weekend looks to be fairly nice with temperatures in the middle to upper 70s Sunday and Monday with skies becoming partly cloudy later Sunday and mostly sunny on Monday. The first half of next week looks fair as well with the next potential for rain and storms coming Thursday into Friday. This will be the result of a warm front over the area and an upper level trough moving across the Plains. && .AVIATION...(For the 06Z TAFS through 06Z Friday night) Issued at 1146 PM CDT Thu May 25 2017 Mainly VFR will continue for the next 24 hours at all TAF sites. The only aviation concern will be a strengthening low level jet tonight causing potential non thunderstorm wind shear right off the surface. Otherwise southerly winds will be breezy around 10 to 13 knots. There will be some gusty winds up to 20 knots Friday morning through the afternoon. There may be the potential for isolated convection around the area late Friday afternoon and evening but confidence is low to mention it in the TAFs at this time. && .SGF WATCHES/WARNINGS/ADVISORIES...

Weather hazards expected... Limited Hail risk. Limited Thunderstorm wind damage risk. Elevated Lightning risk. DISCUSSION... There is a very slight risk for isolated stront to severe thunderstorms through sunrise this morning across portions of Central Missouri. Hail to quarters in size and cloud to ground lightning would be the main risk. Unsettled conditions will begin to develop over the area today. Warming mid level temperatures will develop a thermal cap in the atmosphere today which will likely keep most thunderstorm activity from developing until at tonight. Any activity that does occur today into this evening will ve elevated and produce large hail. .DAYS TWO THROUGH SEVEN...Saturday through Thursday. The overall best chance of strong to severe storms will occur from Saturday afternoon into Saturday night as the cap weakens and very strong instability develops ahead of a cold front which will move through Saturday night. All modes of severe weather will be possible, with the main risks of large hail to the size of baseballs and damaging wind in excess of 60 mph. .SPOTTER INFORMATION STATEMENT... Spotter activation may be needed today or tonight for central Missouri. && More detailed information can be accessed at: http://www.weather.gov/sgf/sitrep This product in graphical format...along with other weather... hydrological and climate information...at http://www.weather.gov/sgf Hatch
