ST. LOUIS, Mo. – A Winter Weather Advisory is in place for much of the FOX 2 viewing area, including the St. Louis metro, from 12 p.m. Saturday until 9 p.m. Driving conditions may deteriorate quickly, especially on any untreated roadways.
Expect mostly cloudy skies on Saturday and snow moving into the northern and northwestern portion of the viewing area by midday. Snow continues to build into the region through the afternoon, arriving in St. Louis between 2 p.m. to 4 p.m. Accumulating snow should be done by about 9 p.m.
For St. Louis, snow accumulations from 1″ to 3″ are possible. Accumulations will be highest in central and northeastern Missouri where up to 4″ of snow may fall.
Temperatures will plummet from the low 30s on Saturday to around 9 degrees Sunday morning. This may cause any slush or water on the roadways to freeze. With gusty northerly winds, wind chills will fall below 0 degrees and as low as -5 to -10 from St. Louis and points north and northwest to start Sunday.
Sunday will stay very cold all day long with highs only reaching the low 20s. Plenty of clouds will be leftover along with a few flurries.
