January through April rainfall 2011-20
Ideal Candidate Radar January thru April ten year average rainfall for Jackson County and the surrounding area was slightly below normal with most locations receiving 18-20" +/-. All counties except Holmes County and Gulf County received only slightly below normal rainfall for the 120 day period and most are ready for spring planting early in the month. The extremes range from a high of 25" NW of Eglin AFB in Okaloosa and a low of 15.4" in Bonifay, Holmes County. A normal winter 2019-20, yet the Radar Rain Shadow that hovers over Chipley and Bonifay is clearly evident. 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. Other area stations continue to document the long term rainfall disparity between upwind and downwind counties. The Pine Log plume that creates wetter conditions for Econfina and Vicksburg continued active during the 120 day period. Very much like the Niceville plume, it is the variable "just right" zone of positive water transit from the Gulf onto the land. Gulf county and areas further east have turned drier. Closer to the radar rain shadow line, Argyle ( wet side ) received 25+ inches while nearby Bonifay ( dry side ) received but 15.5 inches. No weather phenomena can explain this disparity. The microwave energy of the powerful DoD radar inhibits rain storms of the rain shadow area and neighboring storms take up the available moisture resulting in above average rainfall in these areas. Transferring rainfall like this is critically important for future water resources.
