PM Update: Sunsational 70s - savor it

You know the weather is good when we must debate whether this morning’s low near 50 and this afternoon’s high near 70 are too cold or “just right.” For most, it’s the latter it seems. But if you want it warmer, here it comes, with highs reaching into the mid-70s tomorrow and to near 80 over the weekend.

Through Tonight: Clear and crisp with calm winds. There’s a wide range in temperatures with lows near 40 in the cooler suburbs to near 50 downtown.

Friday: Taking the day off to make a four day weekend? Good call. More sunshine galore. That pushes highs into the delightful mid-70s. Winds are light.
