April is a perfect case point.
No rain in April almost always spells drought. Evapotranspiration (left alone) is just that strong. Last year saw record April rain (around 5 inches). This year so far we’ve recorded just under two. That’s not enough to re-flood the swamp, but it is just enough to help keep deep drought at bay.
