Area Forecast Discussion National Weather Service Springfield MO 1217 AM CDT Tue Jun 12 2018 .SHORT TERM...(This evening through Tonight) It was another long hot summer day over extreme southeast Kansas and the Missouri Ozarks. Temperatures warmed into the upper 80s and lower 90s, under mostly sunny skies and light breezes. There is a chance for widely scattered showers and thunderstorms this afternoon and early evening. The environment is not great for micro-bursts. Dry mid levels are keeping severe pulse t-storm indices at low values, despite the high cape. For tonight, look for lows to fall into the low 70s or upper 60s. Organized thunderstorms will be ongoing across eastern Kansas. Some of this activity could reach the Ozarks, however, it should be dying out at the same time it reaches the Kansas and Missouri line. There is a marginal risk of a severe storm or two in southeast Kansas and far western Missouri after midnight tonight. .LONG TERM...(Tuesday through Monday) Outflow boundaries and weaknesses within the periphery of the summertime high will provide scattered thunderstorm chances for the Ozarks from Tuesday morning through Thursday afternoon. Most locations should remain dry, although, many locations will experience some much needed rain. By Thursday night into Friday, models suggest that the summertime high will strengthen over southern Missouri, ending the chances for rain through the upcoming weekend. Look for temperatures warm into the middle to upper 90s in some locations, as the summertime high center assumes a position directly over the Ozarks. There are some signals that deeper moisture will spread into the region next week, and provide widespread rain chances. We will have a better handle on that with future model runs. && .AVIATION...(For the 06Z TAFS through 06Z Tuesday night) Issued at 1202 AM CDT Tue Jun 12 2018 A line of thunderstorms will impact western Missouri overnight. MVFR and brief IFR conditions can be expected at Joplin and possibly at Springfield. Brisk and gusty north to northwest winds can also be expected with this line of storms, with gusts approaching 40 knots likely around Joplin. The storms will then diminish and exit the area by sunrise. There is then some potential for more scattered thunderstorms Tuesday afternoon. We have introduced PROB30 groups to cover this potential. Outside of thunderstorms, surface winds should remain out of the south to southwest below 12 knots. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE.

Weather hazards expected... Limited hail risk. Elevated thunderstorm wind damage risk. Significant lightning risk. DISCUSSION... A line of thunderstorms will push due south across eastern Kansas and western Missouri overnight. There is increasing confidence that these storms may produce damaging wind gusts of 60 to 70 mph, especially across portions of west-central Missouri and extreme southeastern Kansas. Frequent lightning, locally heavy rainfall, and hail up to the size of quarters will also be possible with these storms. The threat for flooding looks very limited given dry soil conditions and the expected quick moving nature to these storms. .DAYS TWO THROUGH SEVEN...Tuesday through Sunday. Heat index values in the middle 90s to around 100 degrees will occur late in the workweek into the weekend. A few strong to severe storms will be possible again on Tuesday as a weak frontal boundary moves into the region. Afternoon and early evening scattered storms will then be possible during the middle and end of the week. .SPOTTER INFORMATION STATEMENT... Spotter activation may be needed overnight along and west of the U.S. 65 corridor. && 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 Schaumann
