Cooler, Windblown Monday
Meteorologists love arcane acronyms: NAM, GFS, ECMWF and vorticity. Another favorite is "persistence", which means the best first guess is to predict a continuation of the current pattern. Just go with the flow.
September was the warmest on record for Minnesota and Wisconsin; 6F warmer than average. 2015 is on track to be the warmest year, worldwide. A stain of El Nino warmth in the Pacific is helping to push mild air well inland, deflecting the coldest winds across Canada. Will a mild bias continue into the winter? Probably.
80s on October 11? Impressive considering the sun is as high in the sky as it was on March 1; 11 hours, 15 minutes of daylight.
In 1977 the residents of the metro area were still scraping 2.5 inches of snow off driveways and sidewalks on October 11, so no complaints. Today would be perfectly average for August 11.
A sharp drop in temperature turns on high winds tonight; a fleeting shower north of MSP tomorrow as the mercury free-falls into the 50s.
No rude, Canadian slaps brewing: 60s for highs this week; a slight chance of a metro frost by Saturday as we limp into fall.

FACT: Increased human fossil-fuel consumption over the past two centuries has increased levels of carbon dioxide in the atmosphere. Atmospheric CO2 recently surpassed 400 parts per million, the highest level in more than 800,000 years.
FACT: As a result of increases in atmospheric carbon dioxide, global surface temperatures have increased by about one degree centigrade since 1880. The 10 warmest years ever recorded—with the exception of 1998—have occurred since 2000. 2014 was the warmest year ever recorded.
