Thunderstorms, A Few Severe, Tonight

Elevated Fire Danger Today

Warming Next Week

Another Round of Record Heat

Local Spring Frost & Freeze Climatology

Behind a southward-moving cold front, thunderstorms are expected tonight. A few thunderstorms could be severe with large hail, especially across northeastern MO and west-central/south-central IL.

Southwesterly winds and low humidity will lead to Elevated Fire Danger along/south of I-70 and along/west of the Mississippi River this afternoon. With potentially erratic fire behavior, it is best to leave burning to the professionals today.

After a cool down Friday into the weekend, warm temperatures will return next week along with opportunities for showers and thunderstorms.

Temperatures will be well above normal on Thursday with widespread 90s for high temperatures. Heat is likely to set records and also the first time St. Louis has recorded a high of 90 degrees more than once for the month of March.

We’ve had some warm stretches that may be getting you excited about outdoor spring planting. But beware, most of the area is still a couple weeks away from their average last freeze dates.
