Missouri – Warm air is surging across the St. Louis region this morning, and dry ground combined with rising temperatures is quickly elevating fire risk across both Missouri and Illinois. Grass and brush can ignite fast under these conditions.
According to the National Weather Service in St. Louis, elevated fire danger is expected through the afternoon as temperatures climb to around 88°F. Humidity drops while light winds shift from the south, creating an environment where fires can spread rapidly across eastern Missouri and southwest Illinois.
Conditions stay quiet through much of the day, with clear skies and strong sunshine warming surfaces quickly. Areas along I-64, I-44, and I-55 may see increased roadside fire risk, especially where dry vegetation is present. Avoid outdoor burning and use caution with equipment that can spark.
Changes begin late Sunday as clouds increase and a slight chance of thunderstorms develops after 10 p.m. While coverage remains limited, brief downpours and gusty winds could impact late-night travel across the metro.
By Monday, cooler air settles in with highs near 58°F. Winds turn north and increase, making conditions feel noticeably cooler after the weekend warmth. Layers will be needed again for the morning commute.
Looking ahead to Tuesday, temperatures rebound into the low 60s with partly sunny skies, offering more stable spring conditions.
Stay alert for fire risk today and shifting temperatures into early next week. Are you noticing dry conditions in your area this morning?
