AREA FORECAST DISCUSSION National Weather Service Kansas City/Pleasant Hill MO 124 PM CDT Sun Oct 24 2021 .Discussion... Issued at 238 AM CDT SUN OCT 24 2021 Today: Overnight, a warm front lifted north across mid Missouri. Storms have stayed fairly well behaved overnight, with most staying below severe limits. A few additional showers and thunderstorms have developed in the warm sector in a broad area of ascent. Severe weather is not anticipated with these morning storms, but brief heavy downpours will be possible. Shower and thunderstorm activity will move out by mid morning and we will see some dry time through the day. Likely will see quite a bit of cloud cover lingering through the day, but expect to see some clearing in the warm sector. Ample southerly flow will continue to draw moisture north through the day. As this happens, increasing cape values up to 2000 j/kg will be in place by the afternoon. Additionally healthy shear approaching 50 knots will also increase through the afternoon. By early afternoon, expect a cold front to be moving into western Missouri. The front will continue tracking east, where eventually storms will ignite along it. Storms are expected to develop east of I-35 and well east of the Kansas City Metro. Most will stay dry, but those in our far western and southeastern counties will want to pay close attention to the skies in the afternoon. Storms are expected to quickly develop and merge into a line with the main severe threat being strong winds. But any storms that can stay more discrete will have a short lived potential for large hail and a tornado can't be ruled out. The line of storms will move out of our area by sunset and will track through southeast Missouri with continued potential for strong winds in those area. But for us, expect a dry forecast to return by late Sunday evening. The workweek: Things will cool off behind the cold front and Monday morning lows may dip into the 30s again for those in northwest Missouri. The rest of the area should expect mid 40s to start the day Monday. Sunshine will return Monday, but its going to remain chilly with highs only topping out in the 50s across the area. Dry weather will continue on Tuesday with a brief warm up into the 60s again. Active weather will return to the area Wednesday and Thursday as a deepening trough swings thorough the midwest. This will bring additional chances for showers and thunderstorms. Highs will return to the upper 50s for the second half of the week with lows remaining in the 40s. Dry conditions will return for Friday into Halloween weekend with highs back to the low 60s to upper 50s. && .Aviation...(For the 18Z TAFS through 18Z Monday Afternoon) Issued at 123 PM CDT SUN OCT 24 2021 Terminals have improved to VFR with a mid level cloud deck in place as southerly winds have increased out ahead of an approaching surface low and cold front. This front will move through the terminals around 20z, with winds turning westerly behind the front and gusting to 25 knots or so. An isolated shower or storm will be possible with the frontal passage, but better coverage of storms will remain east of the terminals. MVFR CIGs should return later this afternoon and remain there through the majority of the period before improving to VFR by mid to late Monday morning. Winds will turn northwesterly overnight tonight with gusts relaxing. && .EAX WATCHES/WARNINGS/ADVISORIES... KS...NONE. MO...NONE. && Discussion...HB Aviation...BMW
