The old version of wxbell had a graphic that displayed the warmest layer between H85 and H7.....I loved it. Now the new graphics this year just have H85 and H7 separately, which can miss the warmest layer that is often around H8. I'm not sure why wxbell did away with the other graphic...it was invaluable. But I think having upper air thermals in general should allow for a fairly accurate depiction of precip type, when sleet is not counted as snow, which it isn't on F5 graphics.
