Next weather system turns Missouri purple with winter weather advisories

Winter Weather Advisories for February 10th, 2019

Winter Weather Advisories expand nearly the entire state of Missouri as the next weather system to bring rain, sleet, and snow Sunday.

A Winter Weather Advisory begins at 12 a.m. Sunday and lasts until 12 p.m. for Chariton, Saline, Pettis, Benton, Camden, Morgan, Miller, Maries, Phelps, Pulaski, Cooper, Howard, Randolph, Moniteau, Cole, Boone, Callaway, Audrian, Montgomery, Osage, and Gasconade County.

A mix of rain, sleet, and snow will move in overnight Saturday into Sunday and last through the first half of the day Sunday. Roads could become slippery early Sunday morning as precipitation begins to fall and accumulate on roads.

With temperatures below freezing Sunday morning, the first type of precipitation to fall will likely be flurries. As this system moves further east through the morning and temperatures rise to near freezing, sleet and rain could mix with snow through Noon.

Snow totals could reach up to 2 inches at most for areas north of I-70. The rest of mid-Missouri could receive a dusting before precipitation transitions to sleet.

What makes this forecast tricky, again, is where temperatures will be as precipitation falls.

Below is a screenshot of Futurecast at 7 a.m. Sunday.

With the freezing line right along I-70 at sunrise, snow and sleet could be falling at the same time across the region with temperatures right at, above, or below freezing. It's likely precipitation will fall as snow Sunday, but it's the temperatures near the surface that will dictate what it falls as.

It is also possible areas of central Missouri will see little to no precipitation, but even freezing drizzle could create slippery roads Sunday morning.

Untreated surfaces, bridges, overpasses, and neighborhood roads are the most prone to becoming slick.
