TALLAHASSEE, Fla. (WCTV) -- It really doesn't take a meteorologist to gauge that it has been absurdly warm for this time of year.
Then again, it's been like this for much of the year.
Through Tuesday, Tallahassee has only had 70 days where the average daily temperature was below normal this year. In the last 30 days, it was four days (mainly around the time Hurricane Irma moved into our area).
One reason why it has been so hot in the eastern United States is the trough-ridge pattern. For the most part recently, we've had troughing (cooler weather) in parts of the west and ridging (warmer) in the east. A relatively-persistent southerly flow over our area has also kept the moisture levels up, and, therefore, the temperatures up - especially at night.
If one were to look at a chart of the daily average temperatures anomalies since Jan. 1, we started off really warm for much of the winter and spring. The summer was fairly close to normal, but temperatures this fall haven't kept up with where we are supposed to be.
How about temperatures overall since records were kept in Tallahassee? Since the 1940s, the trend upward has been small, but it was upward. But that regression line has taken a steep increase one the last three years (including so far this year) has been added.
The last three years (including 2017 YTD), the city's average annual temperatures have been the highest on record (since 1946). pic.twitter.com/XzjmP32zc1— Charles Roop (@CharlesRoopWCTV) October 9, 2017
The average annual temperature was over 70 degrees in the last three years.
The world has been warming, and it seems Tallahassee is included.
