Up to two inches of snow came down across northwest Illinois late Saturday into Sunday morning, but the immediate city area, in yet another repetition of an oft-repeated pattern this winter, received practically no snow. The city’s airport stations reported only flurries, but Harvard, 60 miles to the northwest, received 2.0 inches of snow. Monday becomes Chicago’s 325th consecutive day without at least a 1-inch snow, a record that will be extended several additional days because no snow of consequence lies in the city’s immediate future. Expect no weather surprises through the work week. Storm tracks, the general paths taken by low pressure systems and their associated areas of precipitation, remain north (across southern Canada) and south (near the Gulf of Mexico). Chicago’s weather, distant from storminess to the north and south, remains quiet.
