Area forecast discussion, Jul 21, 6:14 PM CDT, 51 minutes before
Area Forecast Discussion National Weather Service Springfield MO 614 PM CDT Sun Jul 21 2019 ...AVIATION UPDATE... .SHORT TERM...(This evening through Monday) Issued at 157 PM CDT Sun Jul 21 2019 Most of the Missouri Ozarks and southeastern Kansas are experiencing one final day of heat and humidity. All locations are in the upper 80s and lower 90s. There is some variance to dew points due to an outflow boundary which is moving southwest across the area. South of a Nevada to Bolivar to Willow Springs line, dew points are in the lower to even middle 70s. This is resulting in heat indices between 95 and 108 degrees. North of that boundary, dew points are around 70 degrees with heat indices between 93 and 102 degrees. As we get into late this afternoon and early this evening, widely scattered thunderstorms will be possible along that boundary. Coverage will remain limited due to the presence of a dry air mass in the middle and upper portions of the atmosphere. Locally gusty winds will be possible if any of these storms do develop. Much better chances for storms will spread southeast across the area later tonight as a much welcome cold front approaches. We are generally looking at these storms pushing into southeastern Kansas and west-central Missouri sometime in the 9 to 11 PM time frame. These storms will then spread southeast across the remainder of the area overnight. Damaging wind gusts will be possible with these storms, mainly across southeastern Kansas and west-central Missouri in the vicinity of an SPC Slight Risk for severe storms. We will also have to monitor the potential for flash flooding given a rather moist air mass in place. HREF ensembles do indicate some potential for localized 2 to 4" amounts. We will have to closely watch locations where convection trains. One prospect for training could be that outflow boundary. Rain showers and a few thunderstorms will then persist into Monday morning as that front pushes southeast across southern Missouri. We could even see some pockets of drizzle behind the front with a low cloud deck. We went slightly below the model mean for high temperatures Monday due to cool air advection and morning/early afternoon cloud cover. Highs should only warm into the upper 70s and lower 80s with much drier dew points also beginning to advect into the region. .LONG TERM...(Monday Night through Sunday) Issued at 157 PM CDT Sun Jul 21 2019 Surface high pressure will slowly build southeast towards the region before finally settling over the Missouri Ozarks by Wednesday. Dry weather and below normal temperatures can be expected with highs ranging from the upper 70s to middle 80s. Lows will range from the upper 50s to middle 60s. We will see a slight warming trend towards the end of the week as weak height rises overspread the area. Highs are expected to creep back up into the middle and upper 80s by Saturday. We are seeing no signals for precipitation through the end of the week. && .AVIATION...(For the 00Z TAFS through 00Z Monday evening) Pilots flying in and out of the southwest Missouri airports will need to monitor radar trends for thunderstorm impacts tonight and into Monday morning. An upper level disturbance has already forced thunderstorms to develop across eastern Kansas and western Missouri. This activity will become more numerous as the disturbance spreads across the Ozarks this evening and through the overnight hours. There is a damaging wind risk with some of the more intense storms tonight, along with excessive rainfall. Otherwise, if storms are not directly impacting an airfield, VFR conditions are expected. Flight conditions will drop if storms and precipitation does impact an airfield. Safe travels. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. && SHORT TERM...Schaumann LONG TERM...Schaumann AVIATION...Cramer
