Need: Better sounding chart for XC

[a1rres1ster_42]

I'm finding it hard to get an accurate read on cloud base and overall thermal development for planning a good XC day. Does anyone have a good alternative for a reliable sounding chart? I'm based in the US, so something that pulls from a good model like NAM or HRRR would be ideal. I know there are a bunch of different apps out there, but I'm looking for something specific for detailed thermal forecasting. I'd appreciate getting recommendations based on real experience. Thanks in advance.

@a1rres1ster_42 You might want to check out Skew-T plots from the HRRR model.... they're really detailed for cloud base and thermal info. I use them before XC flights, and they give a much clearer picture than basic apps.
