The last time is has been this cold was on the 10 of February, 2010 when the low temperature was -13° and the high temperature was 9°.  As of this Monday, it has been 711 days since we have seen the temperature drop below zero.  This streak will likely come to an end Tuesday night with a forecasted low temperature of -2° into Wednesday morning.

More pressing though, is the combination of the winds and the arctic air, pushing our wind chills well below zero Monday night.  Here is a look at the 24 hour temperature forecast for Fort Wayne:
