Winter Weather Advisory in effect for Christmas Eve, be careful traveling

A flurry or two.

The National Weather Service has issued a hazardous weather outlook for northern IL and northwest IN, warning of a significant risk of excessive cold and dangerously low wind chills throughout the day Monday.

As we dream about a white Christmas, some will see that dream turn into a reality Christmas morning!

Highs: Low to mid 40s.

The highs on Sunday are expected in the mid- to upper 30s. "The air and the ground will not be cold enough in time", WTOP's Matt Ritter said.

On Christmas Day, however, "By the time most people wake up, the precipitation will be over", said Brian Ciemnecki, a National Weather Service meteorologist based in Upton.

The highest snowfall totals will be in northern in, with decreasing amounts as you head south. Indianapolis and areas along I-70 will likely see 2 to 4 inches. Farther south towards the Delaware Valley, it will be more rain, so any snow accumulation should be less than inch, and more likely closer to a coating.

There are actually three low-pressure centers to track; one moving to Ontario, another to western NY, and a new one forming east of New Jersey.

The steadiest rain and snow will fall either side of midnight, and should end from southwest to northeast before sunrise Christmas morning. With clearing skies expected late tonight, re-freezing of surfaces and black ice will cause hazardous road conditions, especially across inland areas where temps just made it above freezing with plenty of standing water.

We've got a WINTER WEATHER ADVISORY through Monday morning for most areas in the Central and South Puget Sound.

CHRISTMAS EVE DAY: Early sun, increasing afternoon clouds. Freezing rain changes over to plain rain by the afternoon as temperatures climb into the mid to upper 30s.

Here are some details on our holiday storm packed with heavy snow, all rain for some, and damaging wind gusts. Temperatures rising to around 32 degrees. But at least this year won't see a "green Christmas" like last year's. The low could be around 18 degrees. While most of the week looks dry, there is the potential for a more sizable storm somewhere off the East Coast by Friday or Saturday.
