We continue to give our full attention to the arctic cold as it continues to push into the state bringing temperatures well below zero. As of 4pm this afternoon, wind chills we already nearing -30°F in the northern part of the state. Newest model data has supported the rising of overnight temps just a few degrees, as it looks like persistent mixing will help keep temperatures a few degrees warmer. However, the wind chills will still be between -30°F and -50°F. After this long wave trough pushes off to the east, warm air advection will move in midweek, and will help to warm us back up to normal. Normal temperatures for this time of year range from the lower 30s in the south to the lower 20s in the north.
The next system that we are keeping an eye on is a surface low that will lift out of the southern plains, and this could produce some light snow across the Iowa/Missouri border, however, this looks to remain light. After this low pushes quickly to the east, this will help warm temperatures through the weekend. There is light at the end of the tunnel, until then, bundle up and make sure no skin is exposed as frost bit can occur in less than 10 minutes. Stay warm, and continue checking back to Iowachase.com for the very latest.
