What has been an abnormal spring as it relates to a lack of severe weather will likely start to change Friday.
According to the National Weather Service (NWS), all of Middle Tennessee is currently under an enhanced risk of severe thunderstorms – mainly during the afternoon through early evening hours of Friday. The main concerns with the approaching storms will be damaging winds and large hail. However, the NWS said isolated tornadoes are possible with this severe-weather system.
According to NWS, a passing cold front will bring scattered severe thunderstorms Friday afternoon with heavy rain and frequent cloud-to-ground lightning strikes. The forecast for Manchester calls for an 80 percent chance of Thunderstorms Friday with a high temperature of 77 degrees and a 60 percent chance of storms Friday night. Once the front passes through temperatures are expected to drop significantly, with the low dropping to near 40 Friday night with patchy frost possible on the Cumberland Plateau. The high temperature for Saturday is expected to be 60 with a low of 37.
So far this spring, storms have been almost non-existent across the country; so much, in fact, that Greg Carbin with the Storm Prediction Center labeled the spring season in “uncharted territory” in regards to the lack of severe weather.
In March, only eight tornadoes hit the United States , tying the record for the fewest tornadoes in March, according to preliminary data from the Storm Prediction Center.
The last time there were so few tornadoes in March was in 1969, said Carbin. Official tornado records started being kept in 1950.
A typical March sees about 80 tornadoes in the U.S.
The pattern began to shift last week when Oklahoma and Arkansas were hit with several twisters. One person was killed in Tulsa, Okla.
