That’s even after September wasn’t usually warm. It tied September 1980 as the 23rd warmest such month on record, 1.4 degrees above average. It marked the 16th consecutive month of above average temperatures in the contiguous U.S. according to the September 2012 State of the Climate report, released by NOAA today.

But Capital Climate says, despite all of these cold weather records, the average temperature over the Lower 48 for the week ending October 6 was 0.1 degree above normal extending a streak of above normal weeks to 43 straight.

Temperatures are forecast to be above normal over the period spanning October 14-22 across much of the Lower 48. (Climate Prediction Center)
