Better keep those sweaters tucked away in storage this autumn because you probably won't need them. The East Coast, South, and Midwest will experience higher-than-average temperatures starting in September and lasting through November this year, according to the Weather Channel. Unusual weather patterns are to blame for the expected increase in temperatures in areas across the country, except in the Northwest region. Southern states like Florida, Georgia, South Carolina, and Alabama will experience a cooler-than-usual September, but the rest of the country should expect to see temperatures rise above average during the month. As soon as October hits, these southern states will follow the trend and get hit with hotter weather too. "You can see that across the entire United States, including Alaska, there is more of a chance that temperatures will be above normal," Dan Collins, a meteorologist with the NOAA Climate Prediction Center-Operational Predication Branch told Live Science. The hotter temperatures will continue through October and spread across the Midwest, Central Plains, Southwest, and part of the Northeast. By the time November arrives, the entire South and Southwest will see above-average temperatures while slightly above-average temperatures hit the Northeast and Midwest.
