Bingo!

For me, this method would not work with v0.20.1 that I had downloaded from the OMweather garage page.
I then uninstalled, activated the Testing Maemo Extras repository and found that version in App Manager and reinstalled.

It now works... go figure

As someone reported, it will not display more than 4 days worth of icons no mater what lay out is selected. Setting "visible items" above 6 will leave only a default 32 degrees for both the high and low temperature and no icon for days past 4.

It ain't perfect but at least it's something until Vlad gets back and picks the project back up.
