Links

http://www.weather.gov/ - This government website by the National Weather Service and the National Oceanic And Atmospheric Administration gives a great amount of information for large or small areas. I like this site because it has very little advertisements to distract from real data, compared to many other ".com" sites.
      --http://forecast.weather.gov/MapClick.php?lat=44.7470586&lon=-91.5015009&site=all&smap=1&searchresult=Eau%20Claire%2C%20WI%2054701%2C%20USA   -   This is the page specific to the Eau Claire area. The sensor used is at the Chippewa Valley Regional Airport in Eau Claire (Lat: 44.88°N Lon: 91.48°W Elev: 890ft)
     -- http://www.nws.noaa.gov/outlook_tab.php  -  This is where weather maps for the country can be found. This map shows areas of high and low pressure, cold and warm fronts, as well as weather advisories like freezing rain or snow advisories. Clicking on the map will bring up even more specific data for those areas.
     -- http://www.crh.noaa.gov/mpx/climate.php - This shows record, average, and actual temperatures for areas in Minnesota and Wisconsin. This makes it very easy to compare current temperature to averages and historical highs and lows.

http://www.weather.com/ - The Weather Channel's website is easier to read and understand the information and maps without any specific knowledge or training in weather patterns. The downside is that the site is plastered with ads for reality TV and "news" stories that have nothing to do with weather.
     -- http://www.weather.com/weather/map/interactive/54701 - This is an interactive radar map of the US. It includes current precipitation, cloud cover, wind speed, and temperature. An animation option allows users to see changes from the past until present or forecast information into the future.
     -- http://www.weather.com/maps/maptype/currentweatherusnational/index_large.html - This is where I usually get the current surface weather maps I use in my blog. It does not have as much data as other sites (like weather.gov), but it is easy to read and see where the high/low pressure systems are, as well as cold/warm/stationary fronts are.

http://www.intellicast.com/ - I find this site to be a good combination of the details on weather.gov with the easy-to-understand qualities on weather.com. Right on the front page is a national current surface conditions map combined with cloud cover and precipitation data. This map makes it very easy to see the links between all these different processes.
     -- http://www.intellicast.com/Local/Weather.aspx?location=USWI0204 - Current conditions for Eau Claire, WI. This page packs in more data than weather.com. I especially like the chart at the bottom that shows temperature change forecast (as well as charts showing precipitation, clouds, wind, etc.). Any site will show the weather forecast, but this chart makes it easy to identify patterns of change over the week.

http://earth.nullschool.net/ - A very informative (and beautiful) interactive map that shows global conditions. Users can look at temperature, wind, ocean currents, and more. Another option allows for viewing conditions at different elevations above the Earth. This can be used to see current Jetstream conditions.
