Currently WXSIM is scheduled to run four times each day: shortly after 7 AM, 11 AM, 3 PM, and 10 PM Eastern Standard Time. Daylight Savings Time is avoided in order to stay synchronized with external data sources and also to avoid complications at the changeover ("spring forward" and "fall back") dates. Just add one hour to the above times if DST is in effect.
It may be interesting to compare previous forecasts with the latest one, and also with conditions as they actually happened. Below are links to the current plus previous twelve detailed forecasts (30 minute intervals) - with the most recent one listed first. "12" is the oldest, going back at least two days.
