This outlook also indicates equal chances for above, near, and below median precipitation across all of eastern OK and much of northwest AR, with portions of Carroll and Madison Counties within an area of slightly enhanced chance for above normal precipitation. This outlook is based primarily on short-range computer models.

- For the 3-month period May - July 2014, CPC is forecasting an enhanced chance for above normal temperatures, and an equal chance for above, near, and below median precipitation across all of eastern OK and northwest AR. This outlook is primarily based on dynamic computer model output, with some input from statistical forecast tools and long-term trends.

- According to CPC, ENSO neutral conditions persisted through April 2014, but with above-average sea surface temperatures developing over the eastern Pacific. ENSO conditions should remain neutral for the rest of the Spring 2014 season, with an increased chance of ENSO conditions developing during the Summer 2014 and beyond. An El Nino Watch has been issued, indicating conditions are favorable for El Nino development within the next 6 months.
