The only thing I miss about rivals is that guy that would do weather reports.

If you want some more detail and reasoning behind the forecast I highly suggest reading the NWS forecast discussion. A brief synopsis of today's discussion is that the models are in agreement with the low track shifting south which would bring more snow into Iowa but there is a good chance that the moisture supply will be cut off or reduced on Friday.

Here is the Quad Cities

Their discussion is my go-to when wanting to know what’s going on.

Yup. I believe there has been an effort to reduce the technical talk on it as well which helps. Compare the local office discussions to the SPC discussions.


Even when it is too technical for me to understand, I still find it useful. Especially when they talk about the trends. For example, they may forecast 13 inches of snow 5 days out, but the discussion might talk about how the models are switching and the dry air may stick around longer.
