A long-duration winter storm system will approach the area overnight, with snow starting across western Missouri around midnight to 3 AM Wednesday morning. This snow will move east over the entire area Wednesday morning, with a switch to a rain/snow mix then rain in the afternoon hours of Wednesday, for all but northern Missouri.
Rain, with some snow mixed in across areas north of the River, will likely last through late Thursday morning before turning to all rain until sunset Thursday as surface temperatures climb above freezing for a while, however, after sunset Thursday, all precipitation will quickly turn back to snow, persisting on and off through Friday.
Overall snowfall totals will be 2″-4” south of the Missouri River and 3-6” north of the River. Any slight change in surface temperature could have major impacts on snow totals, so please keep a close eye on the forecast as we move through the middle and tail end of the workweek.
The upcoming winter weather has prompted the National Weather Service to issue a Winter Weather Advisory which will be in place from 3:00 am until 3:00 pm on Wednesday, January 22, 2020.
