Update
In order to provide as much lead time as practicable for people traveling long distances to the Rendezvous, I will call the Rendezvous destination on this thread on Wednesday, April 20.
I will be monitoring both river levels and weather forecasts leading up to April 20, primarily to make my best guess as to what river levels will be.
Right now based on the forecast and current river levels I believe there will probably be enough water to float the Buffalo.
The AccuWeather long range forecast for Ponca, as of Wed., April 6 indicates that there should be periods of rain prior to the Rendezvous.
Here is a link to AccuWeather web page forecast for April http://www.accuweather.com/en/us/ponca-township-ar/72670/april-weather/2091686?monyr=4/1/2016
Long range forecasts such as these are not reliable but should give us some picture of generally expected conditions. While they give temps, sky cover, and precip, they do not forecast the amount of precip expected or the winds. Based on the information I can find as of today my concern would be the possibility that river levels may become too high rather than too low. But with such long range forecasts that is just a guess on my part at this time.
Rain and/or thunderstorms for April are forecast for the following dates:
April 11,12,13,14,16,17,19,22,23,24,25,26,27
