Chicago-Arlington Heights Snowfall: 3.75 Inches from 2:00 a.m. Thursday to 9:30 p.m. Thursday

A total of 3.75 inches of new snow fell from Thursday 2:00 a.m. through Thursday at 9:30 p.m. in Arlington Heights. The current snow cover depth in Arlington Heights is 10.75 inches. The new snow overnight and throughout the day is light and fluffy/dry. Snow on radar looks diminished. Lake-effect snow has not picked up.

Accumulations expected … as is typically the case with lake effect
snow… additional accumulations will likely vary greatly over
very short distances. Snowfall rates of greater than one to two
inches per hour are likely with the heavier snow showers… which
could locally add an additional 3 to 6 inches of accumulation
overnight into Friday morning… with isolated heavier totals not
out of the question. Storm total snowfall by midday Friday will
likely range from 6 inches away from the lake… to locally over
a foot near Lake Michigan.
