917 FNUS53 KLSX 202105 FWFLSX Fire Weather Planning Forecast for Eastern/Central MO and Southwest IL National Weather Service Saint Louis MO 405 PM CDT Sat Sep 20 2025 Scattered showers and thunderstorms continue across the region this afternoon, with additional chances for rain tonight, tomorrow afternoon, and overnight Sunday. While most of this rain is expected to be scattered, with some not seeing rain at all, confidence is increasing in widespread rain during the work week. Rainfall amounts remain uncertain, though at this point any amount is helpful. RH values will only fall into the 50-60s over the coming days thanks to increased moisture, even where it hasn't rained yet. Winds will persist from the south to southwest until mid week when a system will move through and shift winds to the north.
