PM Update: Superb weather lasts through Saturday; sun may fade Sunday

A few clouds and high pollen counts aside, we tacked on another winner to close out the work week. Those of you who want this to carry over to the weekend get your wish. Saturday is also exceptionally nice, though tending more summery than springlike. Sunday isn’t too shabby either, although clouds may build late.

Through Tonight: . Under clear skies, temps fall steadily through the 60s this evening, with 50s in some of the cooler suburbs by around 9 p.m and after midnight downtown. Early morning lows range from as cold as 40 in the outer north and west suburbs to the low 50s downtown.

The weekend: Little to not like about Saturday. Mostly sunny skies and temperatures make a speedy recovery from the 40s in many spots all the way up to around 80 by late afternoon. Mostly clear and not as cold Saturday night, with lows 50-58 (suburbs-city). Sunday starts off with sunshine but a pesky area of low pressure to the southeast may spread clouds into the area as the day wears on. It’s still pleasantly mild, with highs 75-80.
