Winter Storm Watch issued January 29 at 1:29PM CST until January 31 at 6:00AM CST by NWS Chicago IL
* WHAT...For the Winter Weather Advisory, snow expected. Total snow
accumulations 2 to 3 inches, within a few hour period. For the
Winter Storm Watch, heavy lake effect snow possible. Total snow
accumulations locally in excess of 6 inches possible, mainly near
Lake Michigan.
* WHERE...Central Cook and Southern Cook Counties.
* WHEN...For the Winter Weather Advisory, from 9 AM to 3 PM CST
Friday. For the Winter Storm Watch, from Friday afternoon through
late Friday night.
* IMPACTS...Roads will likely become slick and hazardous. The
hazardous conditions will likely impact parts of the Friday
commutes. Visibilities may drop below 1/4 mile due to falling and
blowing snow.
* ADDITIONAL DETAILS...A burst of accumulating snow is expected mid
to late Friday morning through early afternoon. The snow during
this period may briefly fall at a rate of up to an inch per hour
and make for slick travel conditions. Then, later Friday afternoon
and evening, an intense band of heavy lake effect snow will
develop over southern Lake Michigan, and may impact portions of
central and southern Cook county near the lake for a period Friday
evening before focusing eastward into northwestern Indiana later
Friday night. While the residence time of this lake effect band
over Cook county may only be 3 to 5 hours, the potential for heavy
snow rates of 2+ inches per hour could result in localized
accumulations exceeding 6 inches, particularly near the lake from
the city southward.
Monitor the latest forecasts for updates on this situation.
During lake effect snow, the weather can vary from bands of locally
heavy snow to dry weather just a few miles away. Visibilities can
also vary greatly. Be prepared for rapid changes in weather,
visibility, and road conditions.
