WINTER WEATHER ADVISORY in effect tonight through 9AM Wednesday morning from St. Louis to the north.  Pockets of freezing drizzle expected with a light glaze possible.

Winter Weather Advisory - Wide View

Tonight: Low 32. Patchy fog and drizzle, freezing in spots where it's cold enough creating patchy icy spots.  We'll need to monitor roads closely through the morning drive.  Especially on elevated surfaces like bridges and overpasses. Remember - It only takes a thin layer of ice to result in dangerous travel conditions, so please be cautious while traveling tonight and Wednesday morning.

Winter Weather Advisory - Tight View

Wednesday: High 35. Mostly cloudy skies. Winds: North 5 mph.

Wednesday Evening: Mid to Low 30s. Watch for a round of light rain or light freezing rain depending on temperatures.  Get an update on timing in case some freezing drizzle affects the evening commute, but current thinking is it will develop near or after 9PM into Thursday morning.  best chance for ice is north of St. Louis, but a close call and worth monitoring.  

Weekend Winter Storm Potential:

Friday night through Saturday night:

There remains quite a bit of uncertainty about precipitation type Friday night into Saturday morning.  We may see a rain to brief freezing rain then all snow transition on Saturday morning.  Then wind blown snow is expected Saturday ending Saturday night. While this is what we're seeing now, it is still too early to nail down storm timing and precipitation types.  We expect to see changes and will continue to update the forecast as this storm gets closer and our confidence in the details grows.  

It is possible, if not likely, that our region will see another accumulating snow, but that is highly dependent on storm track and the arrival of colder air. Latest models are not showing as much snow as we had last weekend, but at least a potential for some snow to shovel. We'll be tracking the changes with every model run and we'll keep you up to date.

Weekend Forecast Model

Sunday into Monday: 

Unlike last weekend, this storm will usher in dangerous cold and gusty winds. Winds will crank up late Saturday into Sunday, gusting over 40 MPH. We can expect single-digit lows Sunday morning with highs in the teens. wind chill readings will remain below zero.

Below-zero lows are possible for parts of the area Monday morning with a low close to zero in St. Louis MLK Day morning.
