Winter storm expected to bring several inches of snow to St. Louis area

ST. LOUIS, Mo. — There is a winter storm in the forecast for Wednesday night and Thursday. The heaviest snow will be from the St. Louis metro to the east. Snow will develop from and build in from the southeast to the northwest, toward the St. Louis metro on Wednesday night and continue at least through noon Thursday.

The National Weather Service upgraded its Winter Weather Advisory to a Winter Storm Warning for St. Louis City, St. Louis County, Jersey County, Calhoun County, and Greene County.

Snow will begin after the Wednesday rush hour, with heavy snow for the Thursday morning rush before diminishing from west to east through the afternoon. Remember: do not just focus on the 8" max listed. It is a range: 4" to 8". Some will get 4" and others may push to near 8".

To the west, the gradient between no snow and 4" or more could stretch over only a few miles.

Obviously, standard disclaimers apply. A shift of 20 miles east or west will drastically change the outcome, especially in areas along I-44 through metro STL and west of I-55 in Illinois.

If you are right on the 4"+ and 2" to 4" line, that means you could get 3" to 5" inches of snow. The National Weather Service says that there could be hazardous travel conditions Thursday afternoon and evening.
