662 FNUS73 KLSX 281945 FWSLSX Spot Forecast for Ebo Walker RX...USFS Mark Twain NF National Weather Service Saint Louis MO 145 PM CST Sat Feb 28 2026 Forecast is based on ignition time of 1300 CST on February 28. If conditions become unrepresentative, contact the National Weather Service. .DISCUSSION... There is an area of light rain just to the north of the burn area. But, the burn area is located within a small pocket of clearing. This clearing has allowed for locally enhanced sunshine leading to relative humidity values that are at least 10 percent lower than areas nearby. As a result, relative humidity values are forecasted to remain in the low to mid 20s until overcast cloud cover moves back into the burn area within the next few hours. For the burn area, the biggest impact this afternoon and evening will be the increasing cloud cover that may work to raise relative humidity values slightly to near 30 percent before they rise quickly into the 50s after sunset. Surface winds will be light and southerly this afternoon before a cold front arrives overnight leading to northerly winds for tomorrow. Brief clearing should occur overnight before more clouds move in ahead of the next system that will bring a round of precipitation beginning late Sunday evening. .REST OF TODAY...
