ST. LOUIS – We may still be in winter, but it’s never too early to think about springtime temperatures.

It’s that time for the Spring Weather Outlook.

March

March is never the spring month you want it to be—usually more winter than spring, and generally cooler than you think a spring month should be. Historical data suggests that March’s are getting cooler—meaning winter is lasting longer.

This March is a little different. We will get back to normal temperatures after this cold spell, and that will feel pretty good. Plus, I think we will see some 70-degree readings in March. But that all depends on the rain and storm chances. 

Our active weather pattern will be present with fast-moving storms rolling through, which could set us up for a wetter than normal month. Those rain chances will be followed by a quick warmup or two. Behind the fast storms could be some quick hits of cold, and that’s where we could see a couple of snowflakes. 

Last March started a very wet trend that lasted for a couple of months. 

This March will start dry, with an active pattern over the last couple of weeks—maybe a few strong storms too.

Last March was really mild, with some upper 70s and three 80+ days. 

This year, look for temperatures to feel good after the February chill, but the month will average near normal.

April

In April, we finally start to get a taste of spring. Average highs are in the 60s and lows in the 40s, so the snow threat is generally gone, and we can get some warm days.

The month often brings a mix of sunny days and rainy days, with around 11 to 15 days with rain, hence the old saying, “April showers bring May flowers.” This year we are on track for that.

It’s going to be hard to string dry days together to get out in fields or plan outside events. There may be a little dry stretch in the middle of the month, but don’t count on too much—it’s a bit wet. Temps will stay near average for the month, with some pops into the 70s, but no real warm days. 

Last year, our April was wet with six big events and 8 inches of rain. This year is going to be wet too, but maybe not that wet. Rain chances are higher than normal.

Temps last April were mild and mostly in the 70s and 80s. This year is cooler than that, but we will average a touch above normal.

May

May is a funny month in St. Louis. Some years it can be really warm. We can hit 90 degrees. Some years it can be cool and cloudy and wet, and make you anxious for summer.

But after a relatively wet April, May will open the door to a new pattern—one that could last into June, July, and August. More dry days are coming. That’s kind of odd to say since May is one of our wettest months. But while we normally average 10–12 days of rain, this year it will be less.

Now, those wet days could be stormy, but they will be a little less frequent. With the dry time, and roughly 9 hours of sunshine per day, we will be warmer than normal. 

Last May was very wet with 17 days of rain and a couple of those days totaling over an inch of rain. This year is drier, but look for a few stormy days with severe weather—this is the season after all. 

May 2024 was warmer than normal, with mostly 80s and a couple of 90-degree days.

This year could be warm again with highs that will make summer feel near.
