Area Forecast Discussion National Weather Service Topeka KS 103 AM CDT Fri May 6 2022 ...Update to aviation forecast discussion... .DISCUSSION... Issued at 250 PM CDT Thu May 5 2022 Key Points: - Another round of rain with isolated thunderstorms moves through this afternoon and evening. Locally heavy rain, small hail, and gusty winds are possible with the strongest storm(s). - Dry weather returns to begin the weekend. Much warmer temps arrive next week. The upper low has been slowly circulating across western KS throughout the day, with sfc low pressure passing to our south through OK. Our next batch of rain has gradually progressed into the area from central KS this afternoon with isolated to scattered thunderstorms embedded within the line of showers. CAMs are generally in better agreement with the progression of this line across the area today than they were yesterday. Most locations should see some soaking rain as it moves west to east this afternoon into tonight. East central KS does have slightly better moisture quality and could see the higher totals again as a result, though ensemble solutions area-wide generally are clustering within 0.25- 1.5", with a few up to 2". Still not expecting widespread flooding to be a major concern, but there could be rises in rivers and creeks and localized flooding particularly in those east central KS locations that received the bulk of the rain yesterday. It remains worth monitoring the potential for a stronger storm or two late this afternoon and early evening with a few hundred J/kg of MUCAPE and brief periods of clearing in east central KS. Small hail and gusty winds would be the main hazards with the strongest storm(s), mainly along and southeast of I-35. Showers should gradually taper off overnight as the upper low moves east and wrap-around moisture exits behind it. Skies clear throughout the day Friday with highs near 70 degrees. A low- amplitude ridge moves overhead on Saturday, beginning the warming trend into next week. While a broad upper trough approaches on Sunday with a surface low in response in the High Plains, the cold front is washed out by the time it extends to our area, so precip chances look low with most of it remaining north. WAA increases into early next week with a thermal axis working into the state by Monday. Highs in the 90s and lows near 70 become increasingly likely by Tuesday and Wednesday, which is well above average and the warmest we've been in quite some time. && .AVIATION...(For the 06Z TAFS through 06Z Friday night) Issued at 1258 AM CDT Fri May 6 2022 For the 06Z TAFS, rain showers will continue to impact the Topeka terminals for the first few hours of the period. Visibility will vary with showers in the area, but is generally expected to be MVFR. Rain will move east of sites by around sunrise, but low stratus will remain in place until later this afternoon. A return to VFR is expected around 21Z Friday. && .TOP WATCHES/WARNINGS/ADVISORIES... NONE. && DISCUSSION...Picha AVIATION...Teefey
