Dozens of record lows will be threatened late this week, and some cities could see their coldest temperatures in decades for so late in the season.
This latest round of arctic air will follow right behind Winter Storm Thor. The snow cover left behind by Thor may play a role in just how cold temperatures will bottom out in some cities later this week.
Let's dive into the notables of this latest round of record-breaking arctic air, which entered the northern Plains and northern Rockies Tuesday, and will sweep south and east through late week.
- Lows: Single digits above and below zero from Montana, Wyoming and Colorado to Minnesota, Wisconsin and Upper Michigan.
- Highs: 10-30 degrees below average throughout the Plains and the Midwest. Single digits and teens for highs from the Dakotas to northern Illinois, Wisconsin and northern Michigan.
Wednesday AM Lows and Highs
- Lows: Subzero lows from northern Illinois and northern Iowa to the Canadian border. Teens and 20s in the Mid-South and southern Plains. A handful of daily record lows will be threatened in the Midwest and southen Plains.
- Potential Daily Record Lows (record to beat is in parentheses): Chicago (0 degrees) | Dubuque, Iowa (minus 9 degrees) | Dallas-Fort Worth (20 degrees)
- Latest Subzero High Since 1982? If Chicago falls below zero, it would be the latest in the season a subzero low has occurred there since 1982. Also, it would only be the fifth time since 1872 that a subzero low has been recorded on March 5 or later.
- Highs: Teens and 20s for highs in the Great Lakes and interior Northeast. 30s and 40s push into parts of the South.
