Hi, I tried HYSPLIT HRRR meteorology domain for December 17th of 2017 for latitude 34.55 and longitude -119.169. I selected UTC 2100 after selecting the corresponding met file. But it gave an error. Same problem occurred for Dec 16th as well. I didn't get any problems for dates after Dec 20th, 2017....
