2019 set to rank among the top five warmest years


Global temperatures continue to warm. 2019 is the 43rd consecutive July with above-average global temperatures.

Scientist at NOAA’s National Centers for Environmental Information this July also ranks as the hottest month on record beating July 2016.

2019 will likely rank among the top 4 warmest years on record. Something that has happened every year for the last five years. The top five warmest years on record right now are 2016, 2015, 2017, 2018, and 2014, in that order.

A notable event from July includes Alaska having its warmest July ever. Anchorage reached 90 degrees for the first time ever.

Dayton reached 90 degrees 11 times in July. The average temperature was 3.8 degrees above normal but missed ranking in the top 10 by 0.5 degrees.

A weak El Nino persisted during the summer. Sea surface temperatures have dropped below normal along the equator in the pacific ocean. This marks the end of El Nino.

The index used to monitor the El Nino Southern-Oscillation was only 0.4 degrees Celcius above the long term average. The El Nino threshold requires 0.5 degrees Celcius. The result is a transition to neutral. NOAA scientists do not believe temperatures will reach La Nina by winter.

A neutral winter means temperatures may be cooler than normal. If the Subtropical Jet Stream sets up right the moisture may reach north of the Ohio Valley bringing above-average rainfall to the Miami Valley.
