Terry’s Take: All-time record cold next week?
My goodness everybody, I’ve never seen this on a model before so I felt obliged to share it with you . The 18z GFS ( a US. forecast model) is predicting a low of 31 below in the Quad Cities Wednesday January, 8th. (-32 in Davenport and -33 in Dubuque) This would be brutal but big news as the all-time coldest temperature ever recorded in the Quad Cities is 28 below February 3rd, 1996. During that outbreak temperatures stayed below zero for 120 consecutive hours from January 30th to February 4th. That should give you a pretty good idea of what type of air mass we are taking about. Very, very rare…maybe once every 30 years do we approach such intense levels of extreme cold.
Here’s a wider view of the the lows forecast around the Midwest that morning.
Again, this is just a forecast and to achieve temperatures such as this radiational cooling would have to be maximized. Clear skies, calm winds, dry dense air, and at least 6″ of relatively fresh snow. Even if the model is off 10 degrees we are still looking at 21 below. That is not a pretty picture and I won’t be disappointed one bit if this forecast fails!
