Ideal Candidate Radar January thru March of 2011 thru 2017. This 7 year average rainfall for Jackson County and the surrounding area was normal with most locations receiving 12-16" +/-. March 2013-15 was very wet and improved the 7 year average for every county in the region. The extremes range from a high of 18.5" north of Valpariso in Okaloosa County and a low of 10.2" at Bonifay, near the center of the rain shadow. These 8" disparities are the result of the Radar Rain Shadow. The rainshadow will become more prevalent in the warmer months ahead. Data sources can be seen here.CoCoRAHS, NW Florida Water Conservation District, and at Florida Department of Forestry.

Radar Rain Shadow Jackson Still and Prosperity, two important Department of Forestry rainfall reporting locations, have been closed due to state budget cuts. This is unfortunate as these two reporting stations previously demonstrated the extremes of the Radar Rain Shadow effect. Prosperity still reports occasionally. The notable 8" difference between Bonifay and Argyle is significant as these reporting stations are only 20 miles apart, yet Bonifay received 45% less rain in the 90 day period over the seven year average. As discussed in earlier reports, several CoCoRaHS stations have stopped reporting. Most of these stations are those generally reporting low and below normal rainfall. They were discouraged by the consistent inability to produce "normal" rainfall values.The data produced by these stations was very important and will be missed. Other area stations continue to document the long term rainfall disparity between upwind and downwind counties. The large DoD radar at Eglin AFB inhibits the rain showers headed for the rain shadow area. Neighboring rain showers compete with those weaken showers and take up the added available moisture to create the plume of heavy rain that runs from Fort Walton Beach to Argyle and beyond. Ponce De Leon, Euchee Valley, Bonifay, and other communities in the rain shadow have nearly 50% reduced annual rainfall.
