The outlook for September...

The forecast calls for a 50 percent chance of above normal
temperatures and equal chances of above... below and normal
precipitation through the month.


The 3-month outlook for fall (september/October/november)...

The forecast calls for a 33 to 40 percent chance of above normal
temperatures and equal chances of above... below and normal
precipitation through the period.

Enso (el nino southern oscillation)...
... El Nino advisory continues...

El Nino conditions are present across the central and eastern
Pacific. There is a greater than 90 percent chance that El Nino
conditions will continue through the northern hemisphere winter 2015-
2016. There is around an 85 percent chance El Nino conditions will
last into early Spring 2016.

During the Summer... sea surface temperature anomalies increased
across the central and eastern equatorial Pacific. Across the
continuous United States... temperature and precipitation impacts
associated with El Nino are expected to remain minimal across the
northern hemisphere until the late fall and winter. El Nino will
likely continue to be a contributor to a below normal Atlantic
hurricane season. Climate outlooks and enso discussions courtesy

Note... much appreciation GOES out to our NWS cooperative weather
observers... cocorahs (community... collaborative... rain... hail and
snow network) observers... South Carolina state climate
office... southeast regional climate center... Richland County
emergency services and local weather partners for the data they
provide throughout the year. Their hard work and dedication is
greatly appreciated.
