Weather Impact: St. Louis 10-Day Forecast

Added: 2026-05-14

[00:00:04][music] >> Well, a good Wednesday evening to you.

[00:00:13]It is a cool crisp night, but the clouds rolled out during the day and now it looks like we're going to enjoy another very chilly night across the bi-state area. Listen, it was down to 46° this morning. Some spots tomorrow morning will once again flirt with that 38 39° mark. It's going to be chilly in some of the low spots. We did manage to get to 62 today. Overall, this below average temperature pattern will last one more day and then we're going to swing things a bit as we head into the beginning of the weekend. Rainfall amounts after midnight were certainly much lighter and today all of the stronger storms have been well to our south and southeast.

[00:00:51]And now that the skies are clearing up and we're seeing the winds die down, the temperatures are going down and doing so pretty quickly now that we have uh basically cleared out and you have very light breeze if you have a breeze at all. That has some spots already down into the mid to upper 40s at this hour.

[00:01:10]Our stronger storms, they've been down along the deep south here, Mississippi, Alabama, Georgia. Some of them really have been producing not only heavy rain, but some severe weather, couple of tornadoes reported today, even confirmed. And of course, you may have seen it, uh the snow out around Denver, Colorado Springs. They had a pretty decent snow in many spots, heavy wet snow. You know, Denver's one of those places where you can get the cold air in there, get snow and then a couple of days later it's 70 or warmer and that's kind of where they're going, but that system stays to our south. The next one that's going to impact us as we begin the weekend, it's Friday afternoon, Friday evening. It is what's dropping out of Canada into Idaho, into Montana right now. That will make its way towards the St. Louis area as we head into Friday. Let's start you out at early 7:00 or so Thursday morning. Our anticipation is you may have a few clouds, but in general, it's mostly sunny for most of the day.

[00:02:12]Temperatures are going to climb back into the 60s pretty easily, so despite that chilly start, we do get a nice bump during the afternoon hours. Now, another pretty nice evening Thursday night and going into Friday morning, it won't be as cool as we're kind of turning the pattern ahead of the next weather system, but then during the morning on Friday, clouds begin to increase toward our north and west, and that increasing cloud cover spreads into St. Louis by lunchtime. Going into the afternoon and evening hours, our chances for some showers, that would be on the increase here as we head towards 4:00, 5:00, 6:00. So, during the evening, we may have some showers come through. There's the potential of a rumble or two of thunder, but right now, we're not seeing uh this being a big overall problem. It looks like it's going to last in any one spot for an hour or two, and then it moves on. Now, Thursday, it is once again time for the annual Biz Dash 5K in St. Louis.

[00:03:12]It's known as St. Louis's healthiest happy hour, and you'll be happy about seeing that sunshine. Comfortable running weather here for sure as we head into the afternoon hours. Allergy numbers because of the rain and the chilly weather we had on Tuesday, that pretty much killed the tree pollen, the grass pollen, the weed pollen. Mold count is moderate. Now that we've had the opportunity to kind of break things back down and get the rain out of the air, even though it's been chilly, I think you're going to see the pollens jump back up pretty quickly. They'll jump faster than the mosquito population because these cool temperatures are not good for mosquito breeding. The damp ground and a breeze otherwise would be and as we warm up into the weekend, that'll be something we'll monitor. All right, mid to upper 60s for highs.

[00:04:01]That's your forecast for Thursday. Can't beat it. Let's jump ahead to Saturday.

[00:04:06]We think Saturday is the dry day. We're around 80. It's the warmest day of the weekend for sure. There's another front coming. Remember, we have some evening showers, afternoon evening shower chances Friday. And then on Saturday, mainly dry, but Saturday night here comes another front in from the north.

[00:04:22]It looks like scattered showers would be around early on Sunday for some of us, but they're quickly moving away. So, while there is the opportunity for at least some rain uh over our Mother's Day weekend from Friday afternoon through Sunday, it's not an extended period where we're looking at, you know, rain chances lingering in any one spot for any big amount of time. Most of that would happen overnight Saturday night while all of us are sleeping. And if that timing works out the way we think it will, that's going to set us up for a pretty decent Mother's Day. It'll be a little cooler on Sunday, only in the lower 70s. Next week, there'll be a couple of opportunities for some scattered showers and thunderstorms, but we also see those temperatures warming a bit next week. We go back above average for a change. Um I know we're going to be a little above average, at least close to or a little above average on Friday. Saturday's above average. And then, you know, you're kind of still flirting with average or a little below average Sunday and Monday before we bounce it back. It does look like as we head towards next weekend, not this weekend, but next weekend, we would go back into the mid 80s and as the humidity increases, that also could bring back an opportunity for at least a shower or a thunderstorm. We'll get closer and of course, we'll fine-tune the forecast as we do get closer.

[00:05:55]>> Mhm.
