Although the autumnal equinox or astronomical fall isn't until September 22, the first day of September marked the beginning of meteorological fall.  

Most people are familiar with the astronomical seasons, which correlates with the position of the Earth to the sun and having two solstices and equinoxes each year, and which can have varying dates year to year.

Meteorologists and climatologists mark the seasons using the calendar and temperature cycles instead, which allows for a more convenient and consistent way to compare data season to season and year to year. So meteorological fall runs from September 1 to November 30 each year.

Looking ahead to this year's fall season. the Climate Prediction Center is forecasting above average temperatures for the entire U.S and Alaska. Projections also call for below average precipitation here in the Mid-South for the same period.  The warmer trend looks to continue as June, July, and August also recorded above average temperature for meteorological summer.  However, July and August posted above average rainfall.  

The prediction for fall is based on  projected sea surface temperatures in the equatorial regions of the Pacific and corresponding jet stream patterns across North America.
