A storm with rain, ice and snow will disrupt travel and daily routines in the Midwest and part of Canada, through Tuesday night.

"Enough rain, sleet and snow will fall to cause road conditions to vary from wet to slushy and snowcovered," according to AccuWeather Senior Meteorologist Alex Sosnowski.


"Enough snow and wintry mix will fall or has already occurred at the major airports in Chicago, Detroit, Cleveland and Toronto to lead to airline delays and flight cancellations."

Increasing wind and an injection of colder air will cause some blowing snow and rain to change to snow in some locations.

The exact track of the storm will determine where the heaviest band of snow develops and the dividing line between rain and snow forms.

Just a few dozen miles may mark the difference between mainly wet roads and snowcovered conditions.


A few inches of snow will fall in Detroit and Kalamazoo, Michigan, and Cleveland.

Moderate to heavy snow will fall on Grand Rapids, Lansing and Flint, Michigan, and into part of southern Ontario, including London, Hamilton and Toronto.

"It generally has to snow very hard to accumulate on road surfaces during the midday and afternoon hours during March," Sosnowski said. "However, less-intense snowfall can make roads slippery from the evening to the morning rush hour."

Quick-hitting, heavy snow pushed southward into Chicago during the midday hours. In Detroit, the same conditions with slippery roads can occur during Tuesday evening, when snow moves back in from the west. The worst road conditions around Cleveland are likely to be late Tuesday night.

Bridges and overpasses will become slippery before other road surfaces, as they tend to cool at a faster rate than the surrounding ground.

"The heaviest snow, between 12 and 18 inches (30 and 45 cm), will fall from cottage country, north of Toronto, to Ottawa and Quebec City," Sosnowski said.

South of the snow, rain will soak the middle Mississippi and Ohio valleys on Tuesday into Tuesday night.

The danger of a freeze-up, especially on bridges and overpasses, will expand toward the Ohio River as colder air plunges south later Tuesday night.

Strong to locally severe thunderstorms will affect part of the middle and lower Mississippi Valley into Tuesday evening.

Colder air will settle over the region during the middle of the week and could pave the way for another storm on Thursday.
