Wundergound has launched a cool new tool today called Record Extremes that lets you see and sort US and international records for temperature, rainfall, and snowfall set on a map and a table.

The image above is one I generated for the month of February (so far: 1-23 Feb 2012), looking at daily-maximum-high-temp records and all-time-max-high-temp records for the lower 48. It returned 450 record highs plotted on the map, plus a list of each record in a table format (not shown).

The site is a lot more interactive than this screen save. You can click on each record on the map and see its stats, then zoom in for a closer look.

Many of the icons on the map above are actually bundles of several records in close proximity. As you can see, it’s been a record-breaking February in the US, with some places breaking multiple records (gray icons).

As for the data behind the tool, here’s what Angela Fritz at WunderBlog writes:
