Area forecast discussion, May 25, 3:22 PM CDT, 1 hour 34 minutes before
Area Forecast Discussion National Weather Service Topeka KS 322 PM CDT Tue May 25 2021 .DISCUSSION... Issued at 321 PM CDT Tue May 25 2021 Latest satellite loop and VAD winds show a weak disturbance moving through south central Kansas at 1930Z. Regional radar also shows a small cluster of storms moving across south central Kansas and more isolated convection across east central Kansas southeast of the Turnpike at 1945Z. Tonight, the convection across southern Kansas and east central Kansas may linger through the early to mid evening hours. CAMS solutions vary on the amount of convection coverage this evening across northeast Kansas. Expect isolated convection to be the rule with little in the way of forcing for ascent and a weak sheared environment. Lows tonight will drop down into the low t mid 60s. Wednesday will be dry for much of the day and into the evening hours under the influence of the a mid level ridge. An MCS is forecast to develop across western Nebraska and into northwest Kansas. Models suggest that the MCS should progress eastward into north central Kansas late in the evening and then continue across the region through the overnight hours. Currently given the 850-300mb thickness the MCS should move across southern Nebraska and northern Kansas with a hail and wind threat. Locally heavy rainfall will also be possible as good moisture transport through a deep later is forecast Wednesday night which will increase precipitation efficiency. An outflow boundary will likely be somewhere over east central Kansas and be a focus for storms in the afternoon hours. Parameters for severe weather will be in place for all modes to be possible within the warm sector Thursday afternoon and evening. A return to relatively dry weather occurs Friday into the first half of the Memorial Day Weekend with a return of convection for Memorial Day into next Tuesday. After highs in the 80s on Thursday, temperatures cool off into the 070s for the Holiday Weekend and into early next week. && .AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon) Issued at 1228 PM CDT Tue May 25 2021 Isolated TSRA expected at TOP and FOE through 03Z and may just stay south of the FOE and TOP terminals.

Winds south southwest around 10 kts or less becoming east under 10kts after 15Z. && .TOP WATCHES/WARNINGS/ADVISORIES... NONE. && DISCUSSION...53 AVIATION...53
