AREA FORECAST DISCUSSION National Weather Service Kansas City/Pleasant Hill MO 626 PM CDT Mon May 2 2022 .Discussion... Issued at 251 PM CDT MON MAY 2 2022 Overview: Scattered showers will continue to be possible through this afternoon. An additional round of stronger storms will be possible tonight with strong winds and hail as the main threat. Heavy rain could lead localized flooding. Dry conditions will return after midnight. Another mid-week system will bring additions rounds of showers and thunderstorms. Today: Scattered shower activity continues to push into the area today. A few rumbles of thunder will also continue to be possible. For much of the day, these showers have been struggling to overcome dry air, but we are starting to see more widespread activity spread into the area for the next few hours. A low currently situated over central Kansas will continue pushing to the northeast this evening. Ahead of it, a warm front has been gradually pushing to the north and expected to stall our somewhere near our southern CWA. How far north the warm front can reach this afternoon is a limiting factor in the afternoons severe potential. Additionally, morning activity has limited any recovery in instability. With those factors still in question, the severe threat this evening still remains quite conditional. The highest severe threat looks to remain just south of the KC Metro where the warm front will likely stall out. Highest threat will be damaging winds and large hail. Thunderstorm activity will remain possible across much of the area (beyond area where severe is possible). Precipitable water amounts look to be around 1.5 across the area. With already saturated ground, the strongest storms will pose a flooding threat, especially in urban area. A cold front is expected to push through the area by midnight will push storms out of the area. Tonight and Tuesday: Dry conditions are expected to return late Monday night through Tuesday. We will remain on the gloomy side through Tuesday, with clouds and cooler conditions lingering behind the passage of the cold front. Highs on Tuesday will top out in the lower 60s. Wednesday and Thursday: Dry conditions will be short-lived this week with another trough pushing its way into our area by Wednesday. A bit of a blocking pattern briefly sets up over us which will lead to lingering rainfall chances through thursday. Additional heavy rain and flooding is the biggest concern with the mid-week system with an additional 1-2 inches possible. && .Aviation...(For the 00Z TAFS through 00Z Tuesday Evening) Issued at 625 PM CDT MON MAY 2 2022 MVFR/IFR conditions expected, scattered showers and embedded thunderstorms impacting TAF sites through 03/04Z.
