Ok, now maybe I am overthinking this, but when we sprung ahead, do we have to adjust for the actual east coast time? Before, if the model showed snow at 18z we would subtract 5 hours to get east coast time. I assume it is now 4 hours? You would think I should know this by now! scratch

Yes, model runs are an hour later due to Daylight Savings Time.

I know they are an hour later, but the time on each frame for the weather conditions, we used to take off 5 hours to get Eastern time. Is it still 5 hours or 4?
