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(0.0486*DailyMaxTemp) - 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
