975 FXUS63 KEAX 272309 AFDEAX Area Forecast Discussion National Weather Service Kansas City/Pleasant Hill MO 609 PM CDT Wed Aug 27 2025 .KEY MESSAGES... - Isolated to scattered showers and storms possible late this evening into Thursday mainly for eastern KS and western MO, south of I-70. No severe weather is expected. - Temperatures ranging from upper 70s to lower 80s over the next few days. - Additional spotty chances for showers and storms this weekend into early next week. && .DISCUSSION... Issued at 230 PM CDT Wed Aug 27 2025 Broad mid to upper level ridging continues its gradual eastward track entering the Great Plains Region. Troughing remains over the North Atlantic region as well as the Pacific Northwest. At the surface, a high pressure just to the east of our area has shifted winds across the area out of the south. This high has brought an air mass that has kept high temperatures below seasonal averages for this time of year. Highs today will mostly range in the upper 70s to low 80s. A surface low and its associated warm front emerging out of the Front Range has provided lift for showers and storms to our west over eastern KS this morning. Current (as of 18Z) radar shows returns gradually approaching the area over central and eastern KS. With southerly flow slowly increasing moisture transport and diurnal heating increasing instability, this should provide just enough to allow showers to hold together as they approach our area later this afternoon/early evening. Areas in eastern KS and western MO, south of I-70, will have the best chances for a few isolated to scattered showers this evening. As showers track to the south-southeast, they will be entering an environment with very limited instability (MUCAPE values ranging less than 100 J/kg). Given this, as well as an overall unfavorable environment for storms, severe weather is not anticipated. As we go into the overnight hours, the warm front is anticipated to stall out and become more diffuse to our southwest. A H700 shortwave moves over the area providing increased lift aloft. Additionally, a low-level jet intensifies well to the southwest of our area increasing low-level convergence, reinvigorating convection. Any showers and storms that develop are anticipated to stay along our southern fringes (Linn, Henry, and Bates counties). No severe threat is expected given the very limited instability, unfavorable environment, and better forcing remaining to our south and west. Taking a look from the hydro perspective, the primary threat from the rounds of precipitation expected today and tomorrow will be brief periods of moderate to heavy rainfall. PWATs increase to around 1.2-1.8 inches as a result of increased moisture transport from southerly winds and the low-level jet. This, combined with 10- 12 kft warm cloud layers suggests the potential for a few showers and storms to be efficient rain-producers. The main limiting factor will be the much-lacking instability which will impede storm formation. For Wednesday and Thursday combined, forecasted rain totals range up to 1.5 inches with the higher end of that range concentrated near areas in southern Linn and Bates Counties. Areas south of the KC Metro will mostly likely see a few sprinkles up to around half an inch. Ensemble guidance has significantly backed off forecasted rain totals since yesterday, reducing any potential flooding concerns. Better chances for higher precipitation remain just to the west and south of the area. With the period of precipitation spanning near 24 hours (Wednesday afternoon-Thursday afternoon) and tolerant FFG, the likelihood of any flooding significantly decreases. If any flooding occurs, it will most likely be very isolated. Going into the weekend, highs remain around the upper 70s to low 80s which happens to be just below seasonal averages as another surface high pushes south from eastern Canada. Our winds shift out of the east keeping our dew points out of the 70s. This should make for continued pleasant conditions into early next week. Otherwise, a few spotty chances for precipitation remain this weekend into early next week as multiple shortwaves move through the flow. && .AVIATION /00Z TAFS THROUGH 00Z FRIDAY/...
