ST. LOUIS (KPLR) – Snow amounts are not what we expected within the metro area and for points to the north. However the ice sure was and we are still not done with snowfall.
As we go through this evening the main wave of low pressure is ejecting out of the southwest and will continue to spread snow northeast into the metro St. Louis area up to about I-70. The snow will be light to moderate at times for a few hours in the metro before ending after 9pm. Accumulations will range from 1" to 3" within the metro.
Further south, moderate to heavy snow can be expected through about midnight along and south of a line from Rolla to Steelville, to Ste. Genevieve, over to Mount Vernon. In this region, accumulations on top of the existing 1-2" of sleet will range from 3" to 6".
In addition to the snow, arctic air continues to surge into the region on gusty northwest winds. By morning, low temperatures will be within a few degrees of 0° in most spots with wind chills of -10° to -15°.
Monday is dry, but very cold with near record cold, with a high staying in the teens.
