Severe weather is occurring this hour in portions of Georgia, South Carolina, and North Carolina. As a result, the Storm Prediction Center has issued a Tornado Watch for this region. The watch is in effect through 9:00 PM EDT tonight.
There have already been multiple reports of tornadoes on the ground via dual-pol doppler radar and spotters. Right along the North Carolina/South Carolina border at this hour is a radar-confirmed tornado. That means that the Correlation Coefficient and the Differential Reflectivity has detected debris on radar. This particular tornado currently is just south of Boiling Springs, North Carolina, moving northeast. The area in and near the Tornado Watch will run the risk of a few more tornadoes and damaging wind through the remainder of the evening.
Once the severe weather clears the southeast tonight and Tuesday, that will open the door for the first true blast of below normal temperatures to move right in. High temperatures tomorrow could easily run 10°F to 15°F below normal across areas east of the Rocky Mountains.
There will be a short period of seasonal temperatures middle to late week. However…
A reinforcing blast of below normal temperatures is forecast to move right back in for the upcoming weekend. This week will feature multiple chances for the first good frost/freeze of the seasons to portions of the Great Lakes region.
In summary, the pattern is beginning to take a look of having chilly temperatures across the Great Lakes region. That could bring the first few snowflakes of the season as well. The warm temperatures the Great Lakes region has experienced will be a thing of the past come mid-week.
