Area Forecast Discussion National Weather Service Springfield MO 632 AM CDT Sat Aug 15 2020 ...AVIATION UPDATE... .SHORT TERM...(Today and tonight) It was another typical summer night across extreme southeast Kansas and the Missouri Ozarks. Temperatures dropped into the low to mid 70s, under a mix of clear skies and some cloud cover. Thunderstorms had developed across northern Missouri in response to an approaching upper level disturbance and associated cold front. This energy will approach the Ozarks today, forcing a few showers and thunderstorms across central Missouri and the eastern Ozarks. Most locations across the region will remain dry today despite a few cells developing. The Ozarks airmass is dry for the time of year, as the 00z sounding only showed a PWAT of about 1.20 inches. Therefore we do not expect a high coverage of rainfall today. Again the better chances will be along and east of the Highway 5 corridor, with even better chances east of Highway 63. Look for highs ranging from the low 90s to the middle 80s this afternoon. For tonight, we could experience a few cells lingering in south central Missouri, however this activity will quickly end this evening. Overnight lows will drop well into the 60s. We could even drop into the 50s for locations along and north of the Highway 54 corridor. .LONG TERM...(Sunday through Friday) A large summertime ridge of high pressure will be centered across the Great Basin through almost all of next week, allowing northwest flow and a Great Lakes airmass to spread into the Ozarks. This regime will offer splendid weather conditions that are ideal for outdoor activities. There are no signals for obvious rain chances through the entire extended period from Sunday through Friday. With much less humidity, afternoon high temperatures will warm into the 80s on an afternoon basis from Sunday through Friday. Overnight lows will fall into the 60s. && .AVIATION...(For the 12Z TAFS through 12Z Sunday morning) Pilots flying in and out of the southwest Missouri airports may need to monitor radar trends through the afternoon. However, most locations across southern Missouri will remain dry, as only isolated to scattered showers and thunderstorms are expected. Look for surface winds to be light and variable, especially since a frontal passage from the north northeast will occur today. Safe Travels. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE.
