Dubuque, Iowa

We’re headed to the northern US tonight to see what catastrophe is happing up there. Catastrophes everywhere.

At 1153PM, ET, Dubuque was reporting clear skies and a temperature of -8. Dubuque was smack dab within the upper level trough responsible for the wild weather in the south, and the cold weather in the Plains. A feature tolling along the base of the trough is going to trigger change across the nation.
An inverted rough will be directed to the north from the advancing low in the Lower Mississippi Valley, and will pass over eastern Iowa through the day Wednesday. There won’t be a lot of moisture available to this disturbance, but with temperatures as cold as they are, big, dendritic flurries are more than possible. As the feature propagates, it will elongate, and circulation will become distorted. With less northerly flow, Thursday looks to be the first day of a true warming trajectory.
