Your 1st step is wrong, as the initial raster is in EPSG:4326 it should be: gdal_translate -a_srs EPSG:4326 -a_ullr -104.7 30.8 -103.8 29.8 MRMS_RALA_LATEST.tiff projected.tiff Then your 2nd step will correctly reproject the raster to epsg:3857 for web mercator.

You have "creationOptions" for this: translate_options = gdal.TranslateOptions(format = 'GTiff', creationOptions = ['TFW=YES', 'COMPRESS=LZW'] )


Thank you very much for posting your workflow, this helped me with a similar issue I was having. In case this might be useful to somebody else, I used different python functions for my raster mosaic. In my case, the no data value for the VRT was 255 and because my data only goes from 0 to 100, I masked all the values in my VRTs greater than 100 before ...


There's a QGIS tutorial "Wildfire Monitoring Using The Semi-Automatic Classification Plugin" that seems to cover downloading as well as the necessary analysis steps. I haven't tried it myself but it should be a starting point.
