It was a COLD morning Tuesday! A very dry air mass from northern Canada associated with high pressure settled into the middle of the country causing the mercury to drop into the low teens for most, but down into the single digits for others. While temperatures this morning were very impressive I found it also impressive as to how low the dew points fell...between 5° and 10°. This would be the true definition of an arctic air mass. When you have the cold but also a very dry atmosphere. Even as of 11 am the atmosphere remains fairly dry which combined with the sunshine today should allow temperatures by this afternoon to rise back into the low to mid 30s.
The last time it was cold was back on February 25th and 26th when the low dropped to 12° and 13°. The last time it was colder than 11° was on the 11th of February when the low dropped to 8°. Here's something to ponder on your lunch break...overnight lows this weekend will be warmer than what the high temperature is expected to reach today!
