Intense Snow Possible at Times in Overnight Hours

    Spring may be just around the corner, but there could be flurries in the air overnight as a quick burst of snow is expected to hit the area.

    For most residents of the Chicagoland area, the snow will be nothing to write home about, but for those who live south of Interstate 80, you could see some particularly intense snow at times overnight, due to an effect called “Dendritic Growth.”

    That phenomenon is expected to lead to quick, intense bursts of snow in the overnight hours, with massive snowflakes falling from the sky during that time. Areas south of Interstate 80 in Will and Kankakee counties could see up to an inch of snow as a result of the system moving through the area, according to forecast models.

    In areas north of Interstate 80, the snow will be much less intense, with occasional flurries persisting through the overnight hours and into the morning. A light dusting is possible, but in areas north of the city, residents may not see any snow at all.

    As next week dawns, temperatures will likely stay in the low 40s, but a warm-up trend is coming, and by next weekend the mercury is expected to reach into the 60s, with sunny skies likely as the Chicago-area gets its first sustained taste of spring.
