The National Weather Service says some places from the central U.S. to the Ohio and Mississippi Valleys could be having some frosty high temperatures, as low 20 to 30 degrees below normal.
The Polar Vortex usually stays anchored to the Baffin Bay area north of Canada, when it weakens it causes cold arctic air to spill over onto Canada and the United States giving us the frigid cold we've been experiencing.
Temperatures will drop Tuesday to 10 to 30 degrees below normal for this time of year in places such as Minnesota and the Dakotas. Then the arctic blast will roll east.
By the middle of the week, the freeze zone will sweep the Midwest and the East Coast, plunging lows into the single digits in Indiana and Massachusetts, among other states.
Meanwhile, along the Gulf Coast, a warm front will increase shower and thunderstorm activity in that region and the Southeastern states Tuesday and into Wednesday.
Though this current run in with the arctic blast won't drive temperatures as deep and won't last as long, I know many of people out there are not looking forward to its return.
