Forecast graphics for the modified SHERB (MOSH) and SHERBE (MOSHE) parameters are now available at the following links for the RAP, NAM, and GFS:
We have noticed that the calculated values show relative consistency between models, and the spatial footprints of enhanced values tend to be similar to those of the SPC Mesoanalysis. However, the values on the SPC Mesoanalysis are generally higher than those that we have calculated, again suggesting that there may be some discrepancies in the way SPC is calculating the parameters. I plan to touch base with SPC soon to ask about their progress on calculating individual terms of the MOSH/E parameters in order to determine where the differences arise.
Please feel free to utilize these plots as we transition into the HSLC season and share any insights you have!
