ST. LOUIS - The snow we had last week and the arctic air that arrived Wednesday will drop the temperatures we get tonight to and even below zero for areas that still have deep snow now.

Expect lows in the single digits for the St. Louis metro area, but away from the city and near suburbs, those lows will be in the low single digits. For areas with a lot of snow on the ground, however, clear skies, light winds and a very cold air mass mean lows will be between zero and 3 below.

On Thursday we'll warm quickly with lots of sun and south winds but highs will still be colder than normal when we top out in the low to mid 30s, and then Friday happens. Friday into Saturday, a weather system will arrive from the southwest, bringing a mix of freezing rain, sleet and snow and into the NewsChannel 5 viewing area. That will change to snow Friday night.

It's too early to put numbers on this storm, but accumulations are likely by early Saturday morning when the storm lifts, leaving clouds and highs in the low 30s for Saturday. Expect sun for Sunday, along with highs in the upper 20s.

Winter is coming, folks.
