March 7: Back to Winter

Winter’s chill has arrived again. Today in Nashville, the high only reached 43°, after a morning low of 36. Lows for tomorrow morning will be even colder  in the 20s for most locations.

Tomorrow’s high again will only rise to the 40s.  If you have flowers or plants outdoors that are sensitive, you’ll want to protect them from frost and freeze damage. A few passing flurries are still possible through tomorrow morning. Here’s a look at the latest Futurecast. I think this will all be very light, with the most likely spot receiving light accumulation along the Cumberland Plateau.

Rain will return this weekend and be around both days. We could see 1″ to 2″ of rain.  Temperatures will remain mild near 60 degrees.

Here is some food for thought. March 1 is the beginning of meteorological spring. In spite of the cold temperatures we are experience now, according to Climate Central Springs across the U.S. are getting warmer with climate change. The numbers show that on average, spring has warmed a little more than 2°F in the U.S. since 1970.

The most evident warming is the Southwest as examined by the climate division of NCEI (National Center for Environmental Information). Several cities have warmed more than 5°F, including El Paso, Las Vegas, Phoenix, and Tucson. Climate Central says of the 244 stations across the country they analyzed, only nine (3.7 percent) showed no warming trend at all, and more than half have warmed at least 2°F.  Nashville has warmed 2.4°.

Not only are the spring temperatures getting warmer, but the signs of spring are coming earlier. When you  consider the appearance of first leaves, Climate Central found Spring is arriving in the U.S. an average of three days earlier than a few decades ago.

I’ll have the latest on our chilly forecast on News 4 at 10pm.
