In the next week, a Canadian high pressure will draw in very cold temperatures.
Below is the minimum, then maximum forecast for how much above or below temperatures will be across the US for the next 1-5 days.
Even for the minimum temperature differences forecast, the South is in for quite a cold spell as temperatures warm up a bit in the Northwest.
Above, with the maximum differences, we see just how bad the cold may get throughout Oklahoma, Texas and into the Midwest and Plains.
Out west, temperatures may be warmer than average.
Below is, in order, the minimum and maximum potential temperature differences for days 3-7.
We can see, again, even though this is the minimum forecasted mean temperature difference, the Plains especially will suffer through extreme cold.
For the maximum temperature difference possible for 3-7 days out, it is the Midwest that may suffer the most.
