Today: Low 32/High 38. Cloudy and chilly. Watch for rain to move into the Metro area after 8 PM. Looks like rain tonight for St. Louis with the rain/snow line north of the metro. We expect a change to snow Saturday morning.
Winter Weather Advisory for the News 4 area from midnight to 6 PM Saturday. A Winter Storm Warning is in effect from 3 PM through 6 PM Saturday for Bowling Green, MO and points north.
Saturday: Low 30s to Upper 20s. Windy with snow showers and falling temperatures. A moderate to heavy band of snow may develop mid-morning to early afternoon near the metro. That is one of the keys to snow totals and without it, we may see less than 2". Our current accumulation forecast for St. Louis is 2-4", but there is still a lot of uncertainty in this forecast, so check back frequently for updates.
Weekend Winter Weather Potential:
Tonight through Saturday Evening:
This storm looks to start as rain in the metro after 8 PM or later tonight. Areas north will begin with a rain, mix or snow. The snow/rain line sets up north of the metro for the night. St. Louis sees rain for most of the night. The transition to snow will occur on Saturday morning.
After the transition to all snow at some point on Saturday morning, most likely between 6 AM and 10 AM, wind-blown snow is expected Saturday late morning to afternoon. Snow then lightens and ends Saturday night.
Our going forecast for the metro is 2-4". However, snow amounts are still very uncertain for St. Louis mainly because we are unsure if a heavy band of snow will develop in the morning to early afternoon. If so, we could see 2" to 4" or a bit more. If not, then we'll end up with under 2".
Sunday-Monday Frigid Air:
The coldest air of the season follows this system with highs in the teens to near 20 on Sunday. Monday morning we will face lows in the single digits to low teens.
