Sharp Temperature Split Across the Southeast With Cool 40s and 50s North of I-20 and Warm 60s to 70s Along Gulf Coast From Louisiana Through Florida This Morning
SOUTHEAST — A dramatic temperature contrast is on display across the Southeast this morning, with cool to cold air in the 40s and 50s sitting north of the I-20 corridor while Gulf Coast communities from Louisiana through Florida are already running in the comfortable to warm 60s and 70s.
The sharp divide is creating two completely different weather experiences across the region simultaneously, with northern areas feeling more like early fall while coastal communities are already dealing with rising humidity and warmth. This pleasant cool spell is temporary, with summer heat and humidity waiting in the wings to take over across the entire Southeast.
Cool 40s and 50s Settle North of I-20 From Arkansas Through the Carolinas
Northern portions of the Southeast are waking up to genuinely cool morning temperatures this morning, with readings in the mid to upper 40s covering a wide swath from Arkansas eastward through Tennessee, the Carolinas, and Virginia. Areas across the central tier including Mississippi, Alabama, and Georgia are sitting in the low to mid 50s, providing a refreshing and unusual cooldown for mid-May across the region.
This cool air mass sitting north of I-20 is giving the northern half of the Southeast a brief but welcome break from the heat and humidity that typically dominates the region by this point in May.
Gulf Coast From Louisiana Through Florida Running Warm in the 60s to Upper 70s
South of the I-20 corridor and along the Gulf Coast, temperatures are running significantly warmer this morning with readings already climbing into the mid to upper 60s across Louisiana, Mississippi, and Alabama coastlines. Florida is the warmest zone on the map with temperatures reaching the mid to upper 70s and approaching 80 degrees across the southern peninsula.
The warmth and humidity building along the coast is a clear preview of the summer pattern that is rapidly approaching for the entire Southeast region as the season progresses.
Pleasant Conditions Are Temporary With Summer Heat and Humidity Returning Soon
The cool and comfortable conditions dominating the northern half of the Southeast this morning will not last, with summer lurking just around the corner for the entire region. The temperature map clearly shows the warm and humid airmass already established along the Gulf Coast working its way northward as the season progresses through May.
Residents across the cooler northern zones should enjoy this pleasant weather window while it lasts, as the full heat and humidity of summer are expected to return across the entire Southeast in the days and weeks ahead.
