Snow probably measurable Wednesday night on Thursday afternoon. A winter storm watch was issued for parts of the area south east of St. Louis. And this watch can expand, keep an eye on the updates. This could have a great impact on Thursday morning driving.

The current forecast has snow moving to areas south of St. Louis Wednesday night and to the subway at night and at night. The snow is likely to be diverted in the morning until noon, the snow changes to the east and disappears on Thursday afternoon.
With the current track of the low pressure system that will bring the snow, the best opportunity for the greater accumulation begins with the St. Louis and increases as you travel through the south and east. The lowest accumulation is expected to the northwest. See the map below for the current snowfall potential.
Any change in the storm track can cause major changes to that accumulation map. If the track changes more to the south or the east, we would see that the chances of snow lower and lower the totals around the St. metro. Louis.
If the track changes more to the north or the west, then we would see snow chances increase and the largest volumes return to the subway area.
A second variable is the temperature of Thursday. We all begin the day in the twenties and snow will immediately adhere to untreated surfaces. On Thursday afternoon some areas could see temperatures rise above freezing causing more sliding conditions and some fusion. This could cause the rain to remain with snow in spots, although the snow is lighter in the afternoon.
While the snow ends on Thursday night, observe a refreshment while temperatures fall below the temperature at night.
There is still time to change the storm track and the uncertainty in the temperatures of Thursday. Just a head that we could see more accumulated snow and the chances of a great impact on its Thursday morning. We encourage you to be aware as we make the planned adjustments.
