This year record lows are outpacing record highs across the United States. For Tucson the year so far has been a warm one. But a powerful Polar Vortex kept much of the eastern U.S. in a deep freeze through the winter and much of spring. That cold blast offset the warm records set in other parts of the country.

According to Climate Central "Before 2013, the last time this happened was 1993. That's significant because in a world without global warming, you’d expect to see about the same number of record highs and record lows – not every year since natural weather fluctuations make that unlikely, but on the scale of decades, highs and lows would balance out. Instead, we are seeing the opposite – record high temperatures outnumbering record lows for many decades in a row so far."

Below is a graphic showing the ratio of cold versus hot temperature records across the country.

"On the decadal scale, the gap between highs and lows has been growing since the 1970s. By the decade of the 2000s, there were more than twice as many record highs as record lows. As the planet continues to warm, some projections indicate that this ratio of record highs to record lows could reach 20:1 by mid-century, and a staggering 50:1 by 2100." says Climate Central.

 
This week another blast of chilly air hit the eastern U.S. with more record lows in some areas. However, the ridge of high pressure heating Arizona up next week will also bring warmer weather to the eastern U.S.
