another web site I use regularly is
http://adds.aviationweather.gov which has the ability to look at METAR and TAF, as well as forcast winds aloft. Looking at the winds for Monday (I haven't found another site that does this as well), it indicates you will have a quartering tail wind all the way.
Thanks Ernie. When I do flight planning on Airnav, I tell it to give me fuel that has been reported in the last 60 days.
Also, at OSH, Bassler will come to the hotel (Hilton Garden Inn) and fill your fuel tank while you are having lunch.
