Lehigh Valley winter weather advisory: 3-6 inches of snow Tuesday

The Chicago Department of Aviation said about 790 flights were canceled at O'Hare International Airport and about 220 were canceled at Midway International Airport as of Monday morning. Other airlines reported delays averaging an hour. In its forecast discussion for the region, the Weather Service wrote that the danger of the predicted temperatures "can't be overstated", noting they will be 30 to 40°F (17 to 22°C) below normal. All Georgia state offices will be closed Tuesday and several precautionary measures are taking effect.

The entirety of Minnesota and Wisconsin and much of northern IL is expected to remain below zero for all of Wednesday.

A winter storm brought several inches of snow to northern IL as the region braces for record-low subzero temperatures. Palatine, a suburban Chicago, saw 5.2 inches this morning as the storm created hard travel conditions or drivers and fliers.

Up to 6 inches of snow fell overnight in parts of McHenry County, according to the National Weather Service.

Tuesday: Sleet and snow showers will continue in the west during the morning. The precipitation is expected to end by Tuesday evening.

The weather could break some records. The high on Thusday in Chicago is not expected to top -14 degrees.

The upper Midwest could be hit by -60 degrees Farenheit wind chills, and the upper Mississippi Valley could see chills as brutally cold as -55 degrees Fahrenheit. And heavier snow is expected in the Upper Midwest and Great lakes, meaning "dangerous to impossible travel conditions".

Even snowplow drivers are having trouble keeping up with conditions Monday.

This will be a quick hitter, moving in and out of the region very quickly. Snow is even expected to reach down all the way to MS and Alabama. Areas of Missouri, Illinois, Indiana and OH are under a wind chill watch, while parts of Louisiana, Tennessee, Alabama, Kentucky and West Virginia have been placed under winter weather advisories.

Snowfall will occur in the Dakotas, Minneapolis and St. Paul, Minnesota; and in Central Michigan, where a foot (30 cm) or more of snow is expected, the weather service said.

It will come in as mainly snow but change over to rain in most of eastern MA overnight.

The Weather Service is calling for 6 to 12 inches of total snow accumulations. Not a major snow storm by any means, the rain and snow Tuesday night combined with the Arctic chill to follow does make for a busy week of weather ahead.
