... Another round of mixed wintry precipitation expected Friday and Friday night...
A storm system currently off of the Southern California coast is expected to track through the southern rockies and into the Southern Plains by Friday morning... interacting with Gulf of Mexico moisture and throwing that north into much colder air in place over the mid-Mississippi Valley.
The result will be a rapidly developing wintry mix of snow... sleet... freezing rain... and cold rain on Friday morning over central and southeast Missouri... with this expanding into the Saint Louis Metro area during the midday hours and further east into southwest Illinois on Friday afternoon.
As colder air filters southward on Friday night... precipitation will gradually favor snow with everything coming to an end by Saturday morning.
Snow and some sleet accumulations are expected to reach around 3 inches for areas near the Interstate 70 corridor... with an inch or less for much of southeast Missouri and far southern Illinois. Up to a tenth of an inch of ice accumulation from freezing rain is also possible during this time. Heavier amounts of snow of 4 to 6 inches are forecast for areas north of Interstate 70... where a Winter Storm Watch is in effect.
