Sunday's official high temperature of 33 degrees at O'Hare International Airport stands as a milestone in Chicago weather history.
It marks the 309th consecutive day on which the city's high temperature rose to at least 32 degrees, surpassing the long-standing record of 308 consecutive days at or above 32 degrees recorded in 1878.
With luck, Monday's high temperature -- predicted to be in the low 30s but above freezing -- will extend the consecutive string to 310 days, after which the bottom drops out and temperatures plunge on the first day of the new year.
The record surpassed Sunday is one of a number of rare weather occurrences we are experiencing so far this winter, according to the National Weather Service.
Among them are:
The next chance for snow in the area, according to ChicagoWeatherCenter.com, is maybe Thursday or Friday.
