(KPLR)- Temperatures began to fall Friday afternoon signaling the beginning of an active weekend of weather.  A winter storm will bring a little bit of everything to the St. Louis area as an area of low pressure moves up and over the region.

To the north and west of St. Louis, a band of accumulating ice is possible late Friday night through Saturday.  MoDOT is already warning drivers to avoid Interstate 70 Saturday due to the risk of freezing rain in central and western Missouri. That threat stretches in to Pike, Montgomery, Gasconade, Warren, Franklin, and Lincoln Counties. Calhoun and Greene Counties in Illinois also will see the threat of some accumulating ice.

In the slightly warmer air, heavy rains will fall across southeast Missouri and southern Illinois leading to the threat of flooding.

Two to four inches of rain with locally higher amounts are forecast. The highest rainfall totals will be along and south of a Centerville, Farmington, Ste. Genevieve, MO to  Salem, IL line.

For most of the St. Louis area, a cold rain will fall all day Saturday with an inch of rain in the forecast. The rain will change over to flurries or light snow late Saturday before tapering off early Sunday morning. A dusting of snow is possible in spots.

Those planning to travel for the holidays should be prepared for delays.
