ST. LOUIS — Our next round of storms is on the move this morning, with a Tornado Watch in effect for portions of the area through 8 a.m. A tornado warning has been issued for St. Charles, St. Louis, Calhoun counties until 5 a.m. Take shelter now if you are in the warned area.
A line of strong storms continues marching east, and while straight line winds look to be of primary concern, embedded areas of weak circulation are also anticipated. This line will hold up as it migrates into the St. Louis area around 4 a.m., continuing its surge east into Illinois through the morning commute.
Brief, heavy rain can be expected which will lead to minor flooding in low-lying/poor drainage areas. This line of storms moves out as early as 9 a.m. The majority of the day Tuesday will be dry for some, but there may be scattered showers and storms by the afternoon.
The pattern quiets down Tuesday night, but not for long. Another round of strong storms is expected Wednesday, as early as the early portions of the afternoon. Let’s keep an eye out for all modes of severe weather through the evening hours.
A shift in dry weather is anticipated for Thursday and Friday as temperatures drop below normal (normal high being 74 degrees). A slight chance for a stray shower Saturday before temperatures climb back into the 80s by early next week.
