1. Do NWC SAF Products help in this situation?

 

Cloud top heights are relatively low in this situation

CTTH Product at 17Z

RDT product vaguely catches the convective cell

RDT at 17Z

CR-Ph precipitation product picks up something at 15Z but afterwards is becomes dark and there is no CR-Ph product

CR-Ph at 15Z

 

CRR product shows a small signal

CRR at 17Z

 

NWC SAF products do not seem to capture well this situation. NWP models also did not seem to locate the place of the storm. A Radar would become handy.
