The current mild weather pattern will continue through Thursday, as temperatures will remain well above average for the third week of February.

The morning commute on Thursday could be slowed due to icy roads, as early morning rain will freeze on paved surfaces that will be below freezing.

Warmer air will surge northward during the day and temperatures will approach 50 degrees in the afternoon.

Roads will become wet by midday, as waves of rain will move through Chicagoland during the day. The rain could be accompanied by lightning and rumbles of thunder.

However, rain, snowmelt and frozen ground will combine to create an increased threat for flooding, especially in low lying and poor drainage areas.

By the end of the week, temperatures will dip back into the 30s and then plummet to below freezing by Sunday. The colder pattern is likely to persist through much of next week.
