St. Louis Forecast: Storms possible Sunday
street. LOUIS – Our next set of storms is moving across the state. Heavy rain and storms move east past I-70. By lunchtime, rain and storms will reach 5 On Your Side’s coverage area.
We cannot eliminate the threat of severe weather. This afternoon and into the night, we will have the potential for strong storms. The main issue the Weather First team will be tracking is damaging wind gusts.
The Storm Prediction Center is currently under a slight risk for severe weather (Category 2 out of 5 in intensity) on Sunday. In all honesty, this will likely be a little farther south of our area, with the main threats in southern Missouri, but some of the key spots and movement of the storm are important to the storm threat on Sunday.
Showers and storms will be around midday Sunday as this complex moves from central Kansas eastward. The biggest question that will ultimately determine our severe weather threat: How fast will this move? If you move too quickly and get out of here early this afternoon, the warming of the day could set the atmosphere for a storm to develop. But if it continues around one or two in the afternoon, our threat is much less.
As the main front moves in late Sunday into early Monday, a line of strong thunderstorms is expected to develop. To me, this is the most likely scenario at this point. Areas in southern Missouri, and even a few of our southern communities, appear to be the areas most likely to be affected by severe weather Sunday night.
Sunday will be an alert day for the possibility of severe weather. The bottom line is that the midday rain will not be severe. But if we get a break in the cloud cover this afternoon and the sun comes out, we could see severe weather. We will monitor the terms as they develop and provide you with updates throughout the day.
