    If you've ever wanted to look at historical events, you've probably had some difficulty pulling together all the data you wanted. Here's a list of useful sites I've found - please post if you have any further suggestions!

    NCDC Resources:
    http://www.ncdc.noaa.gov/oa/climate/climatedata.html - This page has links to the resources below, along with many others

    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
    Data Format: Multiple
    Range: 1995 - present

    http://www.spc.noaa.gov/exper/soundings/
    Data: Observed soundings
    Data Format: Images
    Times: Typically 00z and 12z, although special soundings will appear
    Range: Last 7 days

    http://www.spc.noaa.gov/exper/archive/events/
    Data: Multiple (radar mosaic, satellite, HPC surface analysis)
    Data Format: Images
    Range: 1/2000 - present
    Note: To go directly to a date, use http://www.spc.noaa.gov/exper/archive/event.php?date=YYYYMMDD and replace 'YYMMDD' with desired values

    Misc resources:
    http://www.mmm.ucar.edu/imagearchive/
    Data: Multiple types, but most importantly 1km satellite
    Range: 1996 - present

    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

    Yes, I know, that's the site I was actually talking about. It looks like it's back online now. Thanks anyway!

    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.

    I find myself poking around the SPC Mesoanalysis national sector archive quite a bit. It can be very useful for comparing past setups, and also oohing and aahing at extreme days.

    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.
