.DISCUSSION... Issued at 225 PM CDT Mon Sep 8 2025
As of 2 PM, numerous showers and thunderstorms continue across portions of central and south-central KS. These are due in part to a persistent low-mid level WAA pattern. The duration of these storms has been due to the large scale midlevel trough remaining well-west across northeast CO and the mean flow is orthogonal to the initiation zone. Latest WV reveals the main shortwave trough is ejecting into northwest KS and is gradually shifting the axis of rainfall east and southeast. Thus far, MRMS is suggesting upwards of 12" of rain has fallen over portions of Lincoln, Ellsworth, and Saline counties. Fortunately, the heaviest rain is shifting out of these areas.
The LLJ will strengthen overnight from the eastern TX Panhandle through southeast NE. This may provide another focal point for WAA driven showers and storms along and east of the KS Turnpike. PW up to 1.5" once again will support heavy rainfall. Another night/morning of WAA driven convection is possible late Tuesday through Wednesday morning with the best chances west of I-135. The midlevel ridge will slide across the area Thursday into the upcoming weekend. A strong midlevel trough will eject into the northern Plains late Saturday into Sunday, shunting a cold front towards the area for Sunday. The overall pattern will become dominate by an omega block with troughing in the western and eastern CONUS with ridging across the Plains. This is should lead to mostly dry conditions with seasonal temperatures next week.
