The week in Chicago is shaping up to continue its streak of predominantly overcast skies, with today offering a glimpse of sunlight amid a mild high in the upper 40s, as reported by the National Weather Service. Tonight's outlook remains partly cloudy, hovering near the freezing mark, according to the official weather forecast.

As Chicagoans ready their umbrellas, tomorrow promises a blanket of clouds accompanied by intermittent drizzle and daytime temperatures peaking in the mid 40s; this according to the same National Weather Service report. The clouds linger without reprieve into Christmas Day with chances of drizzle or light rain in the morning and highs anticipated in the low 40s, contributing to a potentially foggy Christmas Eve night where a conspicuous Rudolph may serve as the guiding beacon.

Temperature-wise, the holiday night might see a curious stability or even a slight rise, acting as a prelude to a pattern of rather mild weather moving through Chicago, said Fox 32 Chicago. Friday and Saturday are forecast to remain mostly cloudy and mild as well, albeit with Friday's high near the upper 40s and parts of the southern viewing area potentially hitting the 50s.

The city's mild stretch is forecasted to come to an abrupt end by Sunday, when a blast of cold air is expected to plummet temperatures, causing whatever warmth felt at midnight to be the apex for the day, as afternoon temperatures are predicted to fall below the freezing point, according to the same source. This forthcoming cold air promises a blustery Sunday, with mostly sunny conditions and a high merely scraping by 31 degrees.
