    The Weather Angle on National Pi Day

    3.14159 ... that's pi, and the decimal digits go on from there. Since today is March 14, 3/14, today is National Pi Day.


    Pi is the ratio of a circle's circumference to its diameter. One equation using pi has always been a little confusing to me: pi r squared = circumference, where r is the radius of the circle and pi is pi. But, when you read the equation out loud, you are claiming pi are squared, and that is bad grammar and misleading as well. Most people will agree that a pie is round, and that squares with my experience except in the case of square pizza. However, even then, you would say a pie is square, not that pi are squared.

    Now before you come after me with the hypotenuse, let's get off this tangent and back to the weather. Right now, cold air encompasses all of the Northeast. This morning, folks from West Virginia northeastward could accurately claim that there were snow flurries within a radius of 100 miles from their loci. However, at times the clouds will break enough for you to enjoy some of the sun's radians.

    Looking ahead to tomorrow and the period through the weekend and into next week, a series of low pressure areas with precipitation will come toward the Great Lakes and Northeast from different angles. This will determine the variation of temperature degrees with each disturbance and suggest whether you will get a few showers or a protractored period of snow. This video may help you figure out what will happen where you live... and extricate you from my wrecked tangle of text.
