It’s not hard to see why it’s much hotter North than here, they have a dry layer of air at mid-levels providing ample sunshine while we have lots of moisture not only at the surface but in the mid-layers of the atmosphere providing more clouds and rain chances.
On top of that while our air mass is pure Gulf of Mexico tropical humidity, the air trajectories up North are tapping into some hot air from Texas and Oklahoma on a Southwest to NE air flow:
FORECAST MAXIMUM HEAT INDEX LATE AFTERNOON NEXT COUPLE DAYS:
But as I posted yesterday morning we ease back on the thermometer a little the next few days with the increased clouds and scattered thundershowers, then a major front next week brings relief from the abnormally high humidity we’ve had for weeks now.
See the frontal rain location Monday afternoon:

FORECAST LOW TEMPERATURES WEDNESDAY/THURSDAY:
Look at the change in dew point (surface moisture content of air)
FORECAST DEW POINTS THURSDAY MORNING:
Certainly not dry air but much less humid to pair with lower temperatures.
Look at total air moisture Tuesday:
Compared to Thursday morning:
Keep in the back of your mind that this time of year when a front gets into the South Atlantic and Gulf of Mexico a tropical system often develops on the old dying frontal boundary, something to watch next week and the week after. Nothing is shown by models yet.
