A strong southwest to northeast flow of warm, moist air between a very warm southeast US high pressure ridge and a western US trough will efficiently guide round after round of moisture up the Mississippi and Ohio River valleys. The Ohio River is already forecast to go well over flood stage and continued heavy rainfall will only exacerbate the flooding. We are likely entering a period of significant, long term flooding and accelerated spring warm up and green up. In addition to the heavy rain and flooding, growing degree accumulation will accelerate and an early spring will accelerate.
