A SHOVEL FULL OF WINTER....
Make no mistake about it, a couple of hefty shots of cold air are on their way to the Midwest the next week. The first arrives Friday-Saturday followed by an even colder blast Monday-Tuesday. The 10 day temperature departure on the CFSv2 shows the trend.
The GEFS ensemble follows suit.
The EURO EPS ensemble is in agreement as well.
Just look at this massive high pressure that will deliver the cold. The strength at 1047 mb (nearly 31.00") is something you would expect to in the dead of winter.
Look how the high is driving the 500mb jet deeply into the heart of the nation.
Thank goodness this isn't January as the air mass has true Arctic origins. The GFS shows a high temperature next Tuesday of 22 in Cedar Rapids.
