"We are in uncharted territory with respect to lack of severe weather", said Greg Carbin, SPC's warning coordination meteorologist. "This has never happened in the record of SPC watches dating back to 1970."
Since the beginning of 2015, the SPC has issued only four tornado watches and no severe thunderstorm watches, which is less than 10 percent of the typical number of 52 tornado watches issued by mid-March. The approximately 20 tornadoes reported since January 1 is well below the 10-year average of 130 for that time period.
There is no one clear reason to explain the lack of tornadoes, Carbin said. "We're in a persistent pattern that suppresses severe weather, and the right ingredients — moisture, instability, and lift — have not been brought together in any consistent way so far this year."
