Seems pretty straightforward with RAWS data. Maybe time to branch this off into another package for KBDI,10-hour, 1-hour, and even ERC?
KBDI = 10^-3 [ [800 - MoistureDeficiency] [0.968 exp(0.0486DailyMaxTemp) - 8.30] timeIncrement
(1 + 10.88 exp (-0.001736 * MeanAnnualPrecip) ]
MoistureDeficiency = Yesterday's KBDI OR KBDI - rainfall if rainfall exceeds 0.2 inches in a day
Either way:
[ ] Write function to read in wx data (DateTime, Temp, Rainfall)
[ ] Allow KBDI to be a selector for prescription
