Heavier snow showers create slick roads tonight

Remaining Ad Time Ad - 00:00

ROCKFORD (WREX) — The last round of snow from this week's stubborn and slow-moving storm system is the heaviest, with a chance to double or more the previous two snowfalls.

As the slow-moving low pressure deepens, heavier bands of snow are possible. This is likely to develop during the evening hours, primarily after 7 or 8 PM. Roads could quickly become slushy and treacherous, as temperatures drop just below freezing. Bands of heavier snow could lead to reduced visibility through the overnight hours. For this reason, a winter weather advisory goes into effect Friday evening.

Snow to liquid ratios are around 7:1 with this winter event thanks to primarily above-freezing temperatures. This means a wet and heavy snow for shoveling.

Much of this begins to wind down into the early morning hours of Saturday, but could dump several slushy inches. The composition of this snow is pretty wet, with snow-to-liquid ratios of 7:1. This means shoveling is going to be a pain in the neck. The large and wet snowflakes may be pretty while falling, but once they build up, it puts quite a bit of stress on the body to get rid of it. For this reason, this type of snow is sometimes referred to as a "heart-attack snow."

You'll likely have to wait to shovel until Saturday afternoon at the earliest. Scattered snow showers are likely into the early afternoon before finally this stubborn system pushes east. Once all is said and done, a solid 3" to 5" of snow is possible, but some areas could approach close to 6", especially east of I-39.

A winter weather advisory goes into effect Friday evening for most of the Stateline. Regardless of snow totals, slick roads could slow you down through Saturday morning.

The good news with this wintry system is the precipitation is not going to include sleet or freezing rain. Temperatures look to remain above average into early next week, which means melting is quite likely.
