List of sites for historical data (radar, observations, analysis, soundings, etc.)

ESRL 20th Century Reanalysis (great multi-purpose tool for historical weather analysis of many forms): http://www.esrl.noaa.gov/psd/data/20thC_Rean/

Jonathan Finch's (NWS DDC) site (has plenty of analysis of past tornado events): http://bangladeshtornadoes.org/

For the US Cases specifically: http://bangladeshtornadoes.org/UScases.html

Honest question - how the heck do you use the ESRL page? I can't figure it out.

There is another new radar archive (base reflectivity + base velocity) since 1991 - present on the new weather.us
You can zoom-in in each County.

You will find more nice things (high-resolution models, lightning analysis and more) on this site.

Initially, I was a little confused. I chose USA East and then I could not choose Pennsylvania as a state. If I choose USA instead of USA East, Pennsylvania is there. Pennsylvania should probably be included in USA East. New Jersey, Maryland, Delaware Connecticut, and Rhode Island should also be included there.

@Joerg Kachelmann Should that be so?

Yes. All those states are in the eastern half of the US!

I know. Sorry, i mean should that be so that these states are only included when choosing "USA"
