For the deepest of learners:

The process for determining whether or not a day is above or below normal temperature wise is complicated, but works like this.  First add the high & low temps together, then divide the answer by 2.  For example, on December 2nd the high was 49° & the low was 38°.  Those two numbers added up equal 87°.  Divide 87° by 2 and we get 43.5°.  Round to nearest whole number, which in this case is 44°.   Do the same process with the normal high and low temps for the day.  The normal temps on December 2nd are 48° and 36° respectively.  Adding those together gives us 84°.  Divide 84° by 2 and we end up with 42°

The difference between these two numbers (44° & 42°) determines the answer.

44° – 42° =This means December 2nd, 2018 will officially go down as 2 degrees above normal.  

Hope that made at least a little bit of sense to you all.
