It has felt like summer across the Southeast, but a big cool down is about to arrive. A potent upper-trough is moving through the middle of the U.S., which has sent a cold front into western Tennessee and Mississippi. Temperatures immediately behind the cold front are dropping by 10-20 degrees as the coolest airmass of the season (for the Southeast) advances southward.

This front will continue to advance south and eastward overnight and into tomorrow. All of the Southeast will see much cooler temperatures for through Wednesday (outside of southern Florida). Temperatures through Wednesday will fall to below average before rebounding to near average by late week (which will still feel cool compared to the previous week).

High temperatures will be in the upper 60s and 70s. Southern Florida will remain in the low 80s and the higher terrain of Georgia, Tennessee, and North Carolina may struggle to reach 60. Lows will dip into the 30s and 40s–areas closer to the Gulf and Florida will remain in the 50s, but the higher terrain areas (GA,TN,NC) may see temperatures dip below freezing.

Temperature Anomalies For The Upcoming Week (GEFS)

The higher terrain areas of Georgia, Tennessee, and North Carolina need to prepare for a light freeze or frost by Tuesday morning. Please take the proper precautions to protect your sensitive plants.
