ST. LOUIS – It’s going to be a very active week of weather across the bi-state region, with most of the action book-ending the week. Expect a rather potent March-type storm Thursday into Friday.

Look for winds to remain very gusty through at least early Monday afternoon. Sustained winds will reach 25–30 mph, but some gusts will continue to push 50 mph through at least lunchtime. Winds will settle down late in the day.

Skipping ahead to the next big change of the week, Thursday into Friday. A classic looking March storm system will spin across the Mississippi Valley, with rain and wind developing during the day and into Thursday night.

Cold air is now forecast to wrap into the backside of the system as it passes just to our south, and this opens the door to a changeover to some really sloppy, wet snow Friday. If the snow falls hard enough, some of that snow may accumulate. But like that last similar storm back a few weeks ago, this is a very marginal temperature set-up that could just as easily end up being a cold rain. Either way, it’s the next big thing on the charts after Monday.
