Snow ending. Will skies clear in time for Lunar eclipse?

At 8:30 PM CDT, radar indicated that accumulating snow was generally east of I-55, and was shifting off to the east. The snow should end across the immediate metro area by 11 PM. Accumulations have generally been in the 1/2 to 1 inch range, with as much as 1.6 inches reported at Marengo.

Later tonight, a total lunar eclipse will occur. Current RPM model forecasts show that skies should clear across most of the Chicago area around midnight. This is supported by latest satellite imagery, which shows skies clearing along the Mississippi river. The clearing line is shifting eastward and should pass Chicago in time for viewing the eclipse. The exception may be over northwest Indiana, where lake effect clouds may persist much of the night.

Snow continues this evening.

At 6 PM CDT, snow had overspread just about the entire Chicago metro area. Temps were just above freezing, with slushy accumulations on grassy areas, cars, and rooftops. Roadways, including secondary routes were still reported to be wet.

With sunset, temps are forecast to dip just below freezing and snow may accumulate 1 to 2 inches in some areas, again, mainly on grass and elevated surfaces.

Snow overspreading the metro area as afternoon rush begins.

Radar continues to show light snow spreading across northeast Illinois, with bands of moderate to heavy snow embedded within this precipitation area. Temperatures remain just above freezing, and most reporting stations have visibilities of 1 to 2 miles, suggesting that snow is generally melting on contact.

Heavier snow is being reported at Quincy and Macomb in west central Illinois, with visibilities reduced to 1/2 mile. Temperatures are forecast to slowly fall this evening. Areas receiving heavier snowfall may begin to develop slushy accumulations on grassy areas.

As of 3:30 PM CDT, IDOT reported all roads in the area to be wet, but free of snow and ice. This is expected to remain the case on major routes through this evening.

Snow spreading across west, north suburbs

Radar and surface reports indicate that snow has spread across north central, and portions of northeast Illinois. At 3:00 PM CDT the snow was along and west of a line from Mundelein, to Arlington Heights, to Elgin, to Peru. The snow is expected to continue spreading across the metro area heading into this evening.

Where the snow is falling, temperatures are running in the mid 30s so most of what is falling will melt on contact. Also, visibilities are generally around 2 miles.

Heavier snow, with temperatures hovering near freezing and visibilities near 1 mile are reported across northwest Illinois. Some slushy accumulations may begin later this afternoon, mainly on grassy areas. Roadways heading into the evening rush are expected to remain wet.

80 degrees on Saturday-Forget about it… Snow is on the way

Latest area temperatures

Latest area temperatures


Saturday’s 80-degree warmth is but a distant memory this Monday afternoon as this spring’s persistent chill has returned. Early afternoon temperatures are holding in the upper 30s and lower 40s and brisk north wind are adding to  the chill. Light sprinkles are falling across portions of the area and as colder air continues to seep into the region the precipitation is expected to gradually mix with then change to snow and increase in intensity later this afternoon and early tonight.  Light snow is currently falling in north central and northwest Illinois  including Rockford, Moline, Freeport, Rochelle and De Kalb, but with temperatures in the middle 30s, the snow is melting as it hits the ground.

With pavement temperatures well above freezing most of the snow should melt, but as the snow continues through the evening, some small accumulations are possible especially on grassy areas. As temperatures drop into the lower and middle 30s later this evening, some sidewalks, driveways and lesser traveled roads surfaces could gradually whiten with a covering of snow. Snowfall amounts should be  minor, less than an inch, and in most cases just a few tenths of an inch.

Burst of snow to briefly drop visibilities overnight- About 1 inch of snow could quickly accumulate

A narrow, but intense band of snow is approaching the Chicago Metro area from the west and will be moving across the area during the overnight hours. The period of snow will not last long,  about an hour or less but at its peak intensity visibilities could drop to 1/4 mile or lower. With temperatures below freezing, pavements could quickly become snow-covered and slippery. Similar conditions resulted in multi-car accidents in the Minneapolis area Monday afternoon.

The snow will begin in the I-39 corridor including the Rockford area by midnight and spread to the Chicago area by 2-3am and then move into northwest Indiana. The snow should end by morning with many areas getting about 1 inch of snow, though over the entire area accumulations will range from as little as a dusting to as much as 2 inches.
