Wolf,
The web page for the National Space Weather Prediction Center's
Wang-Sheeley-Arge solar wind model displays predictions and observations of
solar wind speed and the polarity of the interplanetary magnetic field at earth.

>As we all know, the effects of the solar wind are strongly determining
