Tornadoes are very rare in the state of Wisconsin during the month of January; however, severe convection did produce at least two tornadoes that moved across far southeastern Wisconsin during the afternoon hours on 07 January 2008<\/strong><\/a>. AWIPS images of the MODIS 11.0 \u00b5m IR and visible channels (above) <\/strong><\/em>depicted one of the early rounds of thunderstorms that produced several reports of hail<\/strong><\/a> around 17:00 UTC (11:00 AM local time).<\/em> Note the unusually warm temperatures and high dew points that were surging northward behind a warm frontal boundary — new daily record maximum<\/strong> temperatures were set for 07 January at Milwaukee (63\u00baF; this was also Milwaukee’s warmest temperature on record for the entire month of January)<\/em> and at Madison (50\u00baF)<\/em>. As this warm and moist air mass began to move over the deep snowpack<\/strong><\/a> (NOHRSC modeled snow depth<\/strong><\/em><\/a>) that was still in place on the previous day (06 January), new daily record high minimum<\/strong> temperature records were also set (39\u00baF at Milwaukee and 37\u00baF at Madison)<\/em>, and dense fog formed that afternoon which reduced visibilities to near zero and contributed to a series of chain-reaction accidents (involving around 100 vehicles) along Interstate 90 near Madison, Wisconsin.<\/p>\n

AWIPS images of the GOES-12 10.7 \u00b5m IR channel (below)<\/strong><\/em> showed the evolution of the severe convection that produced the tornadoes in southeastern Wisconsin between about 21:45 UTC and 22:45 UTC. The corresponding radar imagery from NWS Milwaukee\/Sullivan<\/strong><\/a> revealed a well-defined hook echo as the tornado moved across Kenosha county in extreme southeastern Wisconsin (producing EF-3 damage<\/strong><\/a>).<\/p>\n

Prior to this event, only one January tornado had ever been recorded in the state of Wisconsin — a long-track F3 in Green and Rock counties on 24 January 1967.<\/p>\n
