This outlook is based primarily on short term forecasts of expected weather conditions during the first half of the month, as well as longer term climate anomalies.
  • For the 3-month period December-January-February 2013-14, CPC is forecasting an enhanced chance for above normal temperatures and equal chances for above, near, and below median rainfall across all of eastern Oklahoma and northwest Arkansas. This outlook is based on both statistical and dynamical forecast tools.
  • According to CPC, ENSO neutral conditions remained through November. ENSO neutral conditions are expected to continue into at least late Spring 2014.
