http://www4.ncdc.noaa.gov/cgi-win/wwcgi.dll?WWNEXRAD~Images2
Data: NEXRAD mosaic reflectivity
Data Format: Images
Range: 4/1/1995 - 2 days before present

http://www.ncdc.noaa.gov/nexradinv/
Data: NEXRAD individual products for Level 2 and Level 3

The IEM has an EXCELLENT site to search past warnings (severe tstorm, tornado, and flash flood I think). Included are verification statistics, along with some nice miscellaneous stats such as one that reports how much of a polygon aligns with a county boundary. In addition, there are some radar images from the times of the warnings (and warning updates).

Iowa Environmental Mesonet - IEM COW -> http://mesonet.agron.iastate.edu/cow/

NASA also has a site on which one can view archived RUC soundings (2002, 2005-2010). See http://www-angler.larc.nasa.gov/cgi-bin/satimage/sounding.cgi

Finally, Plymouth State has a nice archive system which allows you to create surface and upper-air maps from previous days (among many other things one can do). See http://vortex.plymouth.edu

This would be useful for looking up SPC events.

examples here:

http://www.spc.noaa.gov/exper/archive/event.php?date=20110427

http://www.spc.noaa.gov/exper/archive/event.php?date=20120414

http://www.spc.noaa.gov/exper/archive/event.php?date=20121225

http://www.spc.noaa.gov/exper/archive/event.php?date=20130210

replace YYYYMMDD with exact event date you want to look up.
http://www.spc.noaa.gov/exper/archive/event.php?date=YYYYMMDD

Was the severe weather outbreak with those 5 tornadoes and 150 wind reports or so saved that just occurred on 2.21.14? I was specifically looking for radar in North Carolina.

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.
