Weather Impact: St. Louis 7-Day forecast

追加: 2026-05-05

[00:00:04]This is a 5 on your side local news update. Happy Wednesday afternoon to you. Hopefully your day is off to a great start. It's a live look up in Grafton right now. The American flag looking good up there. Nice little breeze outside. Temperatures are very comfortable. In fact, there was at Honestly, it was a speedboat that actually went by here this view just a few moments ago. So, some folks are out enjoying the nice weather here this afternoon. I hope you have a chance to do that as well. Temperatures are in the low to mid 70s for us at this hour. 72° for us here downtown. DeSoto just to our south at 79. Scott Air Force Base 74.

[00:00:37]Flora checking in in Clay County at 75°.

[00:00:40]Through the afternoon, we'll see high temperatures in the upper 70s. Mostly sunny. A few clouds roll into the picture late in the evening hours. But otherwise, a very nice afternoon on tap for us. Tomorrow is also going to be nice. A touch warmer with highs in the low 80s across the region. Partly cloudy skies, but again, dry for us here tomorrow. Storm Prediction Center does have a severe weather outlook in our region tomorrow, but there's a little asterisk to this because this actually the outlook for day two goes through 7:00 a.m. on Friday. So, this outlook with a marginal risk, which means isolated strong and severe storms are possible, is primarily for Friday morning. A little bit deceiving. It's a little bit tough to follow there sometimes. But Friday covers, of course, Friday morning and then through the afternoon hours.

[00:01:30]This starts at 7:00 a.m. on Friday. So again, the severe threat really is not in place for us during the daytime tomorrow. It really just goes into effect overnight. This is all the way out into Monday. So again, this is this time of year. We get these types of severe weather threats. What I will say is this is that none of these look markedly impressive for our region.

[00:01:50]There will be severe weather outside of our area to our west and to our south, though. As we check out one of the high-resolution forecast models, this is starting at 10:00 p.m. tomorrow. So, no rain during the daytime hours. But as we move this forward, you can see a line of strong to severe storms moving in from the west. Primarily just heavy rain, frequent lightning, maybe some gusty winds upwards of 50 or 60 mph. In fact, this is the latest update now just coming in.

[00:02:16]Still shows St. Louis dry through about 6:00 a.m. But as we move it forward, you can see it moves over our area. Light to moderate rain expected at this point through your morning commute. Some I want to add on a few extra minutes. You know how things can slow down when the downpours come through the area, especially during the commute. But as we move through 10:15, 11:00 a.m., we'll start to see those showers move off to the east.

[00:02:38]Perhaps a few thunderstorms with that.

[00:02:40]But again, while we're under that severe weather threat, it's very low overall.

[00:02:43]Something else we're watching for is the possibility of a few more storms developing during the afternoon. That's highly dependent upon what happens during the daytime hours with that rain.

[00:02:53]Does it hold longer? Does the cloud cover last? We're not I'm skeptical of this, to be honest with you, especially that widespread with thunderstorms in the area. But that would press eastbound and again, just an isolated severe threat at worst with that. Over the coming days, again, this is that first system. So, it's through here Thursday night, Friday morning. Gets out of here just in time for the weekend. Saturday and Sunday look great. We'll already be watching for our next weather maker developing off to the west Sunday night into Monday bringing another chance of showers and possibly some storms as well. But again, I think the primary severe threat with this setup is actually south of us once again. But we'll continue to watch that and of course, we'll keep you updated here as well.

[00:03:35]The extended forecast period, well, we've got these two main chances of rain. Another one arrives the last couple days of April. So, still somewhat of an active weather pattern with multiple systems moving across the region over the coming days. As we look ahead to the long-term data, the trends in the data show the first week of May with a few rain chances. Nothing too widespread, no major washouts. But check out our temperatures.

[00:04:00]High temperatures first week of May ranging 65 to 75°. Technically, I could have put this up to 70°. So, the first week of May might be really nice temperatures-wise and that will, of course, keep our severe weather threat low as well. So, we'll look forward to that. Over the coming days, though, more detail for us. Today's highs in the upper 70s, low 80s tomorrow. Then widespread rain likely during the morning on Friday with a lower chance of showers and storms through the afternoon. But Saturday and Sunday both stay dry with highs in the mid 70s.

[00:04:31]Looking ahead to next week, more widespread showers and storms possible for Monday. Behind that front, highs only top out in the upper 60s on Tuesday.

[00:04:45]This has been a 5 on your side local news update.
