DETROIT – Today’s high temperature of 44 degrees (6.5 degrees Celsius) sure felt good, right? You see, a cold front crossed the area around that time and, within two-to-three hours, temperatures had plummeted into the mid 30s (1 to 2 degrees Celsius), and that’s pretty much where we’ve been all day. Lows in the low 20s (-6 degrees Celsius), with a west wind at 10 to 15 mph. Temperatures may initially drop into the mid-to-upper 20s (-3 to -2 degrees Celsius), but then rise to near 30 degrees (-1 degrees Celsius) by dawn Wednesday.
