The National Weather Service says the second push of Arctic air is well under way with northwest winds once again pushing 20 to 25 mph along with gusts to 35 mph or more. As a result, temperatures had generally already reached their daytime highs across the state and will slowly fall the rest of the day. As of late this morning, temperatures ranged from the balmy upper single digits above zero across southern Iowa to chilly around -10 degrees across far northern and northwest Iowa.

Once most of the rest of the state dips below zero this evening, widespread temperatures above zero will not be seen until mid to late Thursday morning. In the meantime, numerous daily record lows and minimum max temperatures look to be set tomorrow and Thursday morning. Lows will range from around 30 below zero across the north and northeast to the teens below zero across the south and west. Throw in some winds, and wind chills will range from around 40 below to 60 below zero at its worst overnight and Wednesday morning.

The most dangerous conditions will be across northern and northeast sections of Iowa, though no place will be immune from the dangerous conditions Wednesday. Morning lows will range from around 30 below in the north and northeast to the teens below zero down and over to the Missouri and Nebraska borders.  Highs will not be too much better with nearly all of the state topping out below zero, ranging from around 20 below zero in the northeast to near zero in the southwest. Dangerous temperatures will continue into Thursday with lows once again ranging from around 30 below in the northeast to the single digits below zero in the southwest.

Ideally, one should stay inside and out of the cold. Though for anyone that must go outside, multiple warm layers and covering ones face will be a necessity. This kind of cold is life-threatening if the right precautions are not taken.
