Fair skies, chilly Saturday night

Lows in the 20s

DETROIT – Happy Pi Day, Detroit! It's Saturday, March 14, or 3/14, or 3.14. "3.14" is the famous mathematical figure for Pi, the ratio of a circles circumference to it's diameter. Even more amazing, the Pi's first 5 numbers are 3, 1, 4, 1, 5, and 3.14.15 is the date. Even more epic, at 9:26:53am and 9:26:53pm, the first 10 digits will be represented; 3.141592653!  If that numerical fact brought flashbacks of math class, don't despair. Mother Nature has dreamy weather for the weekend. Enjoy sunshine with pie on your Pi Day!

Math geeks and Foodies unite. Also, Albert Einstein was born today in 1879. Check out this archived Pi Day story featuring my Local4News buddies and me.

Mother Nature will keep the switch flipped to "Spring" Monday. Detroiters can savor this day with mostly sunny skies and highs near 60 degrees or more. It will be great for students itching to ride their bikes or play basketball outdoors.
