ST. LOUIS - Morning commuters will enjoy the calm before the storm Friday afternoon.
The St. Louis area will be dry through the morning, but chances of storms increase from the west ahead of a cold front by midday.
This powerful system is already bringing snow on the northern side of a low pressure system in Nebraska and South Dakota. However, our area will not see snow, but we could have a few storms headed this way that will become strong to severe late Friday afternoon, especially east of St. Louis. Damaging winds, or an isolated tornado, are possible with this line.
Storms will get going for the metro area by around 12 – 1 p.m., and could intensify to the east after 2 p.m. The Storm Prediction Center has much of the viewing area in a marginal risk for severe weather Friday.
Beyond that, temperatures will fall through the day with high temperatures spiking around lunch time, and cool off as the front sweeps through. We'll be quite windy today and Saturday, with gusts up to 30 mph both days - that wind will have a bite to it on Saturday.
The St. Louis area won't quite hit freezing overnight, but it will still be cold with lows in the mid-30s.
This weekend will be CHILLY! Highs only top in the upper 40s both days, and we'll fall into the 20s Sunday morning.
I expect frost will develop if winds remain pretty calm.
