Low pressure is forecast to intensify as it moves from Iowa northeast into Wisconsin and Lower Michigan during the next 24 hours.

Rain will spread over our area from the west and south and winds will gradually strengthen, shifting from southeast to southwest later tonight. Downpours with strong thunderstorms may occur here after midnight.

A High Wind Warning will be in effect Chicago area wide from Wednesday morning into Wednesday evening, with west to southwest winds gusting from 50 miles per hour to as much as 60 mph, with the strongest winds likely in the late morning into early afternoon.

These extremely strong winds could down trees and power lines with associated power outages, as well as make travel very difficult, especially for high-profile vehicles. High Wind Warnings/Advisories will also be in effect for portions of adjacent areas/states (gold and tan-shaded areas on the headlined map).

Note also on the headlined map, Winter Weather Warnings (Pink-shaded areas) for 6- to 12-inches of accumulating, blowing and drifting snow are in effect through Wednesday, including areas just north of the low pressure track from Nebraska, through northern Iowa and southern/central Minnesota, and into northern and central Wisconsin and Upper Michigan.

Travel will be extremely difficult and dangerous in these areas.

AAA predicts the second-highest number of travelers in over a decade this week. But for millions of Americans planning to travel this Thanksgiving, this is not the forecast they wanted to see. Some travelers are already feeling those effects.

There were about 1,000 cancelled flights Tuesday, nearly a quarter of them in and out of Denver. Some airlines are beginning to waive change fees ahead of expected delays.
