Effective Tuesday, March 1, 2011, the National Centers for
Environmental Predictions (NCEP) Hydrometeorological Prediction
Center (HPC) will transition the HPC Probabilistic Freezing
Temperature charts to operational status. These charts depict
the probability of minimum near surface temperatures falling to
32 degrees Fahrenheit or less at 6 hour forecast intervals out
through 156 hours. These products are derived from the National
Digital Forecast Database (NDFD) temperature forecasts and the
2-meter temperature grid spread from the Global Forecast System
(GFS) ensemble.
The products are available online at:
