ST. LOUIS - The Five On Your Side team of meteorologists are tracking an atmospheric one-two punch that could amount to some snow for parts of the Bi-state by Wednesday evening.

At this point, it looks to be a light accumulator for us with the system aiming for the western part of Missouri and Kansas City where one to three inches of snow is forecast.

First punch: Cold air begins to filter in later Tuesday evening into Wednesday. Wednesday temperatures will likely remain in the 30s for highs.

By Thursday and Friday, highs will be in the upper 20s to near 30 degrees!

Second punch: A weak system coming from the Pacific Northwest to arrive late Wednesday. By the afternoon, we may see a brief period of light snow or flurries.

Any possibility for snow would end during the overnight hours Wednesday with very low chances for anything more than a dusting around St. Louis.

That said, there will be some snow covered roads for Thursday morning’s commute. And we feel the best chances for accumulation will be from Metro St. Louis and the Mississippi River westward.

We are watching for another weak system to skirt by the area over the weekend with yet another chance for some light rain or snow.
