    Hello and thanks for such a good forecasting service. Since yesterday evening, i.e. about 24hrs ago, there have been 2 small blue patches at Ban Chiang, about 40 km east of Udon Thani and they are still there now in fact. Why?

          Hello Suty and sorry I missed your message 7hrs ago. Those 2 blue spots cleared at around that similar time and they're now gone completely. If they reappear I will send a screen shot. Cheers, David.

            Hello Suty,
            I'm sorry I missed your message and screenshot request, but those 2 patches gradually disppeared as this afternoon's stormy skies where taking the screen over, but if they do reappear I'll send a screenshot.
            Cheers!
            David

              Hello Suty,
              The 2 blue patches are here again, near Ban Chiang, about 45 km east of Udon Thani and left of centre of this screenshot.

                This is likely an artifact related to radar echoes.
                Only the radar data provider could answer your question.
                Check the Internet for examples of causes of “radar artifacts”.

                    Radar artifacts? OK, I'll Google those, thanks!
