Sorta...right now, it's 7pm Eastern on Thursday and the farthest out Intellicast Windcast goes is 8am EST Saturday. So not exactly 24 hours.
There are better tools/models for long-term:
^Different models have different opinions.
Finally, the National Weather Service produces graphs for each of its forecasts points, which go out a lot longer than 48 hrs. Here's one for my airport: http://goo.gl/gD4ZL
To get yours, go to http://www.weather.gov/ and type in either a 4-letter Airport ID, or a city, state. You'll get the NWS forecast page for that location. About 2/3 down on the right-hand column is the Hourly Weather Graph. Click it. Then adjust the date and time. It goes out at least 5 days and includes a lot more than wind.
And here are more short-term tools that may give a second opinion when times get closer: http://www.emc.ncep.noaa.gov/mmb/SREF_avia/FCST/NARRE/web_site/html/wind...
Plus, there are airport forecasts (incl. ceiling, vis) which are available for a lot of airports that don't have TAFs and do go out at least 48 hours:
Now, you talking Intellicast, I like their Humidicast. Where the humdity is high in the day, bad weather is likely. Where it's low, good weather is likely. So it's a great "first look" type of tool.
There are SO MANY tools out there that the FAA considers supplemental weather information; it's a shame more pilots don't use them.
