AREA FORECAST DISCUSSION National Weather Service Kansas City/Pleasant Hill MO 627 AM CDT Sat Apr 30 2022 .Discussion... Issued at 333 AM CDT SAT APR 30 2022 It has been a dark and stormy night for much of eastern KS and western MO; however, rain is expected to be mostly out of the area by sunrise. While cloudy skies remain, temperatures are expected to reach back into the mid to upper 60s for most of the area with far NW MO around 60F and central MO in the low to mid 70s. As the surface low which brought last nights storms moves toward the NE, some wrap around light precipitation is possible for far NW MO. Cloudy skies continue north of the MO River through Sunday with highs once again in the 60s and 70s. The pressure gradient remains quite tight as the low pressure center passes to the north keeping winds gusty through Saturday and Sunday with generally westerly winds around 15-20 MPH gusting to 25-35 MPH Saturday and 25-30 MPH Sunday. The weather pattern remains fairly active after the weekend. Another wave from the west CONUS spins up a leeward surface cyclone this time across the southern Plains. Showers and thunderstorms are possible Monday night into Tuesday morning as the low pressure center passes over the area. Hot on its heels is another storm system that looks to move through Wednesday and Thursday bringing with it more chances for widespread showers and thunderstorms. One might say spring has arrived as winds consistently maintain 10-15 MPH thanks to diurnal heating, temperatures fluctuate between highs in the 60s and 70s to lows in the 40s and 50s, and routine waves of thunderstorms return. && .Aviation...(For the 12Z TAFS through 12Z Sunday Morning) Issued at 626 AM CDT SAT APR 30 2022 A low pressure system is passing by the area to the NW then north. At the moment, there is an area of clearing over the terminals. Sky coverage increases through the morning as clouds wrap around the low from the west. CIGs remain mainly VFR; however, some MVFR CIGs are possible. Gusty winds move into the area from the west aided further by solar heating this morning. Westerly winds sustain around 15-20 kts through the day with gusts around 30-35 kts dissipating after sunset. && .EAX WATCHES/WARNINGS/ADVISORIES... KS...NONE. MO...NONE. && Discussion...Pesel Aviation...Pesel
