Lakeshore Flood Warning continues in effect for northeast Illinois until 10AM CDT Sunday – winter storm rages to the north

Update 7:45PM CDT…

The Lakeshore Flood Warning (Dark green-shaded area on the highlighted map)  continues in effect for the Illinois lake Michigan shoreline in Cook and Lake Counties until 10AM CDT Sunday. Strong east to northeast winds gusting to 40 miles per hour will continue to build 10 to 15-foot waves which will in turn threaten to inundate low-lying flood-prone areas along the shoreline.

The Wind Advisory for northeast Illinois expired at 7PM CDT and was not extended..east to northeast winds will continue into Sunday, but most gusts are expected to diminish slightly, for the most part staying in the 30 to 40 mph range.

The Winter Storm continues to rage to our north with Blizzard and Winter Storm Warnings and Advisories (see areas on map below) headlining heavy blowing and drifting snow, sleet and freezing rain making travel treacherous from Minnesota through Wisconsin into Michigan. Over two-feet of snow is expected in the Green Bay area.

Update 8:15AM CDT…

With east to northeast winds potentially gusting in excess of 50 miles per hour , building waves 12 to 18 feet, the Lakeshore Flood Advisory has been upgraded to a Lakeshore Flood Warning (dark green-shaded area on the highlighted map) this Saturday morning. The Warning will continue overnight until 10AM CDT Sunday. The Wind Advisory (brown-shaded areas on the highlighted map) for winds gusting to 45 to 50 miles per hour inland continues  until 7PM CDT this evening. Note the Winter Storm Warnings/Advisories (see map below) continue in effect to our north, northwest and northeast beginning just north of the Illinois-Wisconsin  and the Indiana-Michigan border with increasingly more dangerous travel conditions due to heavy blowing and drifting snow mixed with sleet and freezing rains the farther north you go – over a foot of snow could occur in some areas of Minnesota into Wisconsin – storm conditions will continue into Sunday.

With Low pressure intensifying over the Central Plains and approaching our area, a Wind Advisory calling for east to northeast winds 25 to 35 miles per hour with possible gusts to 50 is in effect between 7AM and 7PM CDT Saturday over a good portion of northeast Illinois mainly along and north of Interstate-80 (brown-shaded area on the highlighted map including Cook and Lake Counties. These strong winds will cause 10 to 16-foot waves to develop resulting in elevated lake levels and flooding of susceptible areas with a Lakeshore Flood Advisory in effect Saturday/Saturday night into Sunday morning for areas adjacent to the Illinois Lake Michigan shoreline (green-shaded areas on the highlighted map).

The center of low pressure is forecast to track east, passing over our area Sunday. The north side of the system is expected to produce 8 to 15-inches of blowing and drifting snow with Blizzard and Winter Storm Warnings/Advisories in effect (see map below) from South Dakota and Nebraska and northwest Iowa across Minnesota and Wisconsin. Travel north could become very hazardous just across the Illinois-Wisconsin state line with conditions further deteriorating as you go farther north and west.
