ST. LOUIS - Arctic air continues to be firmly entrenched across the St. Louis metropolitan region Friday.

As of 7 a.m. Friday, southern Missouri and southern Illinois are blanketed by as much as 10 inches of snow.

Another disturbance pushing northeast from Oklahoma will provide more snow for the area Friday afternoon and bringing the areas with the heaviest snow totals of about 12 inches. The area stretching from Lesterville to Farmington to Chester to Mount Vernon will also receive around 12 inches.

In the metro St. Louis area, another one to three inches of snow is expected before the system tapers to flurries late Friday afternoon.

As the sky clears overnight, temperatures will drop into the single digits with wind chills below zero.

Another weather system will pass through the area Sunday but should only bring a chance for light precipitation.
