Record Setting Heat…in many ways

 Everyone is talking about it…it is so hot outside. This time of year the average high is 71 and the average low is 48.  We are way above that. So hot today that we set several records. In Nashville, the high was 87, tying the record high. The low was 67 tying the record for the warmest low on the date.  Crossville also set a new record with 83 degrees.

Tomorrow will be another hot, possible record setting day with a high near 88.  A front moves in Thursday with rain and thunderstorms.  There is a marginal risk for severe thunderstorms, that’s a 1 on a 1 to 5 scale. Here’s the timing on the rain and thunderstorms from Futurecast.

The cooler air moves in after the front passes by…fall returns…lows in the 40s and highs in the  60s.

Hopefully this will be the last of excessive heat this fall.
 On the heat record subject, NOAA released its monthly global temperature findings for September 2016 this morning. The recent 16-month streak of record warmth ended.  September 2016 was the second warmest September on record. September was 1.60 degrees F above the 20th-century average. That misses last year’s record for the month by just 0.07 degrees…very close.  Using the temperature data for overland only, it was the hottest September since NOAA records began in 1880. This graphic represents the year to date global map showing NOAA temperature anomoalies. Climate Central used a 20th century baseline. Notice the heat over Alaska, the western Atlantic Ocean and the Amazon Basin.

The NOAA results are close to those released from NASA yesterday, which indicated that September 2016 was 0.007°F warmer than the previous warmest September in 2014.
To better represent how much the temperature has changed since the early industrial era, Climate Central combined the NOAA and NASA global temperature data and adjusted it to a baseline of 1881-1910. This is reflected in this graphic.
