 This is my first line source.  It provides current temperature, wind speed/direction, barometric pressure, relative humidity, and rainfall for the UW-Eau Claire campus.  It also gives the data graphed across daily, monthly and yearly time frames.  I like to use this source first because I know the station is taking data for my immediate location.  For large weather providers they might make broad projections across my region but the exact conditions within Eau Claire could vary.

This is a real time motion animation of the current wind speed and direction across the continental United States.  I go to this site immediately after the metstation because it allows you to see air movement caused by pressure cells very intuitively.  I find that it is helpful to use the wind movement to make predictions that I can then compare to a weather providers projections of fronts and cells.

This is my primary source for surface data and upper atmosphere projections. The surface data contains a lot of information: fronts, cells, wind direction/speed, as well as severe weather.  Very good for explaining current conditions and predicting air mass movements.

I use this as a supplemental source of surface data.  It also contributes temperature projections across the country.

Wunderground has current conditions for Eau Claire.  Although the metstation is my primary source for that it can be interesting to compare the two as well as look at its three day forecast.  Along with Accuweather it has broad temperature projections for the country.
