**4 Concurrent Member Ensemble - Probability Plots **

The ensemble probability fields available from this page are simple numerical probabilities based upon the four concurrent members, where each member has equal weighting in the calculation. For example, if one of four solutions satisfies the given criteria the probability would be 25% (if two of four, then it would be 50%). Due to the high resolution of the simulations, probabilities calculated in this manner are not appropriate for storm scale fields such as updraft helicity, updraft velocity, etc. Neighborhood probabilities, which are appropriate for storm scale fields (as well as reflectivity output), are also available from the HopWRF home page.
