With anticipated high temperatures only reaching the lower 30s, and overnight lows in the teens, the weather the latter half of this week will mirror Chicago’s normal temperatures for January 1 (32 degree high and 17 degree low).
Low pressure, moving through the Chicago area Monday night and early Tuesday, will be followed by polar high pressure. Precipitation accompanying this transition is expected change from rain to light snow or flurries later Tuesday as low pressure pulls away to the east, and north winds on the leading edge of polar high pressure knife into the area. The cold air is forecast to moderate slightly heading into next weekend, but will still remain well below normal.
Ahead of this sharply colder air, south winds will boost readings to the low 50s both Sunday and Monday, as deepening low pressure triggers a few showers on Monday.
