About The 6 Hourly QPF Products

These forecasts depict isohyets of accumulated precipitation of 0.01, 0.25, 0.50, and 1 inch expected in each six hour period. The Senior Branch Forecaster generates the six-hourly forecast for Day 1. The QPF forecaster, known as the Day 2/3 six-hourly forecaster, generates the Day 2 and Day 3 six hourly products during 2 shifts per day (~ 9am-5pm/9pm-5am EST), issuing QPFs for eight consecutive six-hourly periods ending on synoptic hours.
