Weather Summary
National Weather Service Quad Cities IA IL
817 AM CST Sat Feb 17 2018

Departing high pressure allowed mostly cloudy skies to build
across the middle Mississippi River Valley overnight. These clouds
were ahead of an upper level disturbance and low pressure over
eastern Colorado. Morning low temperatures ranged from 6 in
Independence, to 21 in Fort Madison.

The aforementioned disturbance and low pressure will continue to
move eastward, reaching the Mississippi River Valley late this
afternoon. Precipitation associated with this disturbance will
reach eastern Iowa late this morning, and will begin as all snow.
By this afternoon, warming temperatures will allow snow to mix
with or change over to rain, especially for locations south of
Interstate 80. Over these areas, expect little to no snow
accumulation. To the north, snow accumulations of a dusting to
half an inch are possible, especially along the Highway 20
corridor. Daytime high temperatures will range from the lower 30s
along Highway 20, to middle 40s over northeast Missouri.
Precipitation will wind down this evening as high pressure builds
across the region. Clearing skies overnight will help low
temperatures drop into the upper teens to lower 20s.
