Rainshadow Posted November 29, 2018 Report Share Posted November 29, 2018 I posted this a couple of times during the Mid November event and having a PSA buried in a 30 page thread is as useful as a snow thrower in Miami. For whatever reason, this is an issue with the Tropical Tidbit site, but not Pivotal Weather. I don't know if there is a sniff of snow at the start of the 6 hour time step or the sfc temp is less than 35F the algorithm assumes it is snowing throughout the six hour time period, but the pivotal site does not have the same issue. Here is an example from today's FV3 GFS in which near the snow/rain interface where it was raining throughout the six hour period, snow was still accumulating. Below is the Pivotal Weather website output (both 10:1) during the same time. Quote Link to comment Share on other sites More sharing options...
