FYI - TAF 24 to 30 HR Format

[Amish RakeFight]

If you haven't already heard, beginning November 5, 2008 the TAF will cover a period of 30 hours.

On November 5, 2008, with the 1800 UTC issuance, the NWS will change the TAF format to conform to international standards outlined in ICAO Annex 3. The change includes the initiating of 30-hour TAFs for high-impact U.S. airports. To accommodate the extended TAF period, the format of all TAFs will change.

The change involves identifying the date associated with each time group. As shown in the example below, the previous TAF code is modified by adding the appropriate date before the forecast hour.

i can't imagine how accurate these new TAF's will be. I bet they will be so accurate that they can tack on another 6 hours of their highly accurate forecasts
