Winter weather possible Tuesday into Tuesday night


ST. LOUIS, MO —  A cold front moved through early Sunday morning and temperatures are falling along with gusty winds out of the northwest which will cause wind chills in the teens for most of the afternoon. Flurries will also be possible, but won’t amount to much.

A few spots of light snow will be around Monday evening into early Tuesday morning, but better snow chances stay north and northeast of the St. Louis region.

The main concern for the week ahead is Tuesday-Tuesday night. This system is still far away but confidence is growing that winter precipitation will affect much of the region. One question that still remains is how much snow accumulation we will see. This is largely dependent on the track of surface low. There are still some uncertainties with the track. Snow amounts will also depend on when the “icy mix” changes over to all snow, which will happen from the northwest to the southeast late Tuesday afternoon into Tuesday night.

Based on the latest data, there is a good chance that much of the viewing area will see 2″ or more of snow. How much more is still a good question.

To break it down geographically:

Areas from St. Louis to the northwest will see mainly snow from late Tuesday afternoon into Tuesday night.

Areas from St. Louis to the southeast are likely to see a mix of sleet and snow starting late Tuesday afternoon before switching to all snow during the evening.

Further south will have more of a freezing rain and sleet system to deal with, with some glazing/ice accumulation possible.

As the system gets closer we will be able to get more detailed in the snow and ice accumulation forecasts. Stay tuned.
