Knox Severe Watches & Warnings NOAA Weather Radio

Special Statement
Statement as of 2:18 PM CST on December 22, 2014

...Christmas eve snow...

A storm system will impact central and southeast Illinois late Tuesday night into Wednesday...bringing a mixture of rain and snow to the area. Temperatures will initially be warm enough to support mostly rain...but as colder air aloft gradually arrives from the west...the precipitation will change to snow on Wednesday. The heaviest snow will likely fall Wednesday afternoon and evening east of the I-55 corridor. At this time...it appears 1 to 2 inches of snow will accumulate east of I-55...with less than 1 inch further west into the Illinois River valley.

For those with Holiday travel plans on Wednesday...please be aware of the potential for slick and hazardous driving conditions. Considerable uncertainty still exists concerning the location of the heaviest precipitation axis and the exact timing of the change from rain to snow...so keep abreast of later forecasts and statements for updates.
