Heather’s Weather Whys: Making big strides toward spring

March can be one of Buffalo’s most extreme months when it comes to storms and temperature swings. That’s partly because we’re quickly gaining daylight this month.

If you go by daily high and low temperature records, March can be pretty extreme.

It’s been as warm as 82 degrees and as cold as minus-7. These big temperature swings are a part of the growing pains of the inevitable spring season. 

During the next few weeks, the length of daylight in Buffalo will increase close to three minutes each day. Longer periods of daylight and a higher sun angle mean that warmer air will start to win the battle against the colder air.

But why is it that we gain a few minutes back per day in March but only a few seconds per day in late December? The simplest answer: Earth is a sphere that rotates on a tilted axis as it revolves around the sun.
