The majority of the HSA received 3”-5” of rain this month. Most of northwest AR, as well as far northeast OK, received only 25%-75% of the normal July rainfall this month, though portions of Crawford, Sebastian, and Franklin Counties ended the month above normal. The remainder of eastern OK saw near normal to around 200% of normal this month, and central Pittsburg County received over 300% of the normal July rainfall.
|
- Several cold fronts brought well below average temperatures to eastern OK and northwest AR in July 2014. Far northeast OK and northwest AR received below normal rainfall this month, with much above normal precipitation across southeast OK.
|
- No mainstream river flooding occurred in July 2014.
|
- According to the Drought Monitor from July 29, 2014, Extreme Drought (D3) conditions remained across Pawnee, southwest Osage, and western Creek Counties in northeast OK. Severe Drought (D2) conditions were Osage, eastern Creek, western Okfuskee, western Okmulgee, western Tulsa, Washington, northern Rogers, Nowata, and Craig Counties in eastern OK. Moderate Drought (D1) conditions were present across Ottawa, southern Craig, southern Rogers, Tulsa, eastern Okfuskee, Okmulgee, northern Mayes, western Wagoner, Adair, eastern Sequoyah, and western Choctaw Counties in eastern OK, and Crawford and Washington Counties in northwest AR. Abnormally Dry (D0), but not experiencing drought, conditions were occurring across the remainder of eastern OK along and north of I-40, as well as southern Pushmataha and Choctaw Counties.

| Outlook |
- The Climate Prediction Center CPC outlook for August 2014 (issued July 31, 2014) indicates a slightly enhanced chance for above median precipitation and equal chances for above, near, and below normal temperatures across all of eastern OK and northwest AR. This outlook is based on short-range forecasts of expected weather conditions, primarily for the first half of August.
|
- The Climate Prediction Center CPC outlook for the 3-month period August-September-October 2014 indicates an enhanced chance for above median precipitation and equal chances for above, near, and below normal temperatures across all of eastern OK and northwest AR (outlook issued July 17, 2014). This outlook is based on both statistical and dynamical forecast tools and considering El Niño conditions.
|
- According to CPC, current atmospheric and oceanic observations suggest a transition from ENSO neutral to El Niño conditions is underway. El Niño is still favored to be in place by early fall, though the uncertainty about the pace of onset and intensity have increased slightly. An El Niño of weak to moderate strength is most likely.
