NWS Springfield, MO wrote its last area forecast discussion before the first event at Jul 20, 5:15 AM CST, 6 hours 45 minutes earlier.
Area Forecast Discussion National Weather Service Springfield MO 615 AM CDT Mon Jul 20 2020 .SHORT TERM...(Today and tonight) Issued at 250 AM CDT Mon Jul 20 2020 Convection has all but dissipated across the forecast area early this morning except for a few showers across portions of central. An upper level shortwave trough is moving across the central Plains and convection has developed in Nebraska into northern Kansas early this morning. This activity will move to the southeast this morning. Models are showing that the mu cap over the area will start to weaken the next couple hours. Once this occurs there should be just enough lift for some isolated to scattered showers and storms to start developing through sunrise mainly along and north of Hwy 60 this morning. This activity should start to wane by mid day. Then additional scattered showers and storms are expected to develop during the mid afternoon hours into early this evening. The entire area could be affected by this activity but the better coverage and chances should be north of Hwy 60. Not expecting widespread severe weather, but there could be a few strong storms with winds to around 50 mph and penny size hail the main risk along with frequent lightning. Heavy rainfall will also occur with any storm. Anywhere multiple storms track over the same location there will be a localized flooding risk from early this morning through early this evening. The storms should start to dissipate by the mid evening hours today. Additional storms will develop across the Plains tonight into early Tuesday morning. The better chances should remain to the west and north of the area but this activity should clip the western and northern potions of the forecast area. Locally heavy rainfall and lightning will be the main risk with this activity. Highs will warm into the upper 80s to the lower 90s this afternoon. Humidity will not be as high with heat index values in the middle 90s to around 100 degrees. Clouds and storms will also have an impact on temperatures this afternoon. .LONG TERM...(Tuesday through Sunday) Issued at 250 AM CDT Mon Jul 20 2020 Scattered pulse type storms will then be possible Tuesday afternoon and evening. The better coverage will likely be along and east of Hwy 65. A few strong to severe storms will be possible with wind gusts up to 60 mph and penny size hail the main risk with a few of the strongest storms. Frequent lighting and locally heavy rainfall will also occur with the storms. Highs in the upper 80s to the lower 90s will occur on Tuesday with heat index values in the middle 90s to around 100 degrees. An upper level ridge will start to build back over the region by the end of the week into the weekend. Highs in the upper 80s to the lower 90s will occur through mid week with highs in the lower to middle 90s expected Friday into the weekend. Heat index values in the middle 90s to around 100 will occur on most days through the week. This weekend heat index values in the 100 to 105 range will be possible. Widespread rainfall is not expected through much of the week, but isolated to scattered storms will be possible each day, but not all locations will be affected. && .AVIATION...(For the 12Z TAFS through 12Z Tuesday morning) Issued at 610 AM CDT Mon Jul 20 2020 Scattered storms will occur at times from this morning into early this evening across mainly west central and central Missouri. At this time the better potential appears to remain just north of the TAF sites. Left any mention of thunder out of the TAF sites as coverage will not be as good to the south so confidence in the TAF sites being effected were to low to include. Will continue to monitor and amend the TAF is the potential increases. Another complex of storms will develop across the Plains tonight and could approach portions of west central and central Missouri late tonight into early Tuesday morning. The better potential will be north and west of the TAF sites. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. && SHORT TERM...Wise LONG TERM...Wise AVIATION...Wise
