The cold March of 2013

610temp.new

March is in the books and most people could not be happier since it was the 5th coldest since 1939 in Charlotte. That’s when they moved the official observations to the airport. The average temperature for the month was 46.1° which was 5.1° below the 30 year average. If you go back to 1878 when records began in Charlotte this was the 8th coldest on record. What makes this March seem so much colder is the fact that last March we had the 2nd warmest on record. So in the span of a year we went from one of the warmest March’s on record in Charlotte to one of the coldest. We only set one record low though of 26° on the 29th. The highest temperature all month was 79° set on the 16th. The coldest was 21° on the 4th and 4th. We had a trace of snow on the 2nd and the 6th. Rainfall ended up with 3.44” which was actually 0.57” below normal. 22

Looking ahead to April I expect things to warm up but only to about average for this time of the year. The good news about April is even below normal temperatures are warmer than the average temperature in March. The cool weather yielded 22 of the 31 days with below normal temperatures.

The rest of the Southeast was just as cold with many location measuring top ten coldest March months on record.
