The image above is from the European ensemble control run, which is a member of the ensemble set that has its parameters unchanged. As you may recall, ensemble members are forecasts from the model itself, but their starting parameters are slightly changed in one way or another. The control run does not have its parameters changed. This forecast, valid for the evening of April 8th, has a massive warm-up across much of the nation, with every state east of the Colorado Front Range (except a few select New England states) reaching full-on spring or summertime warmth.
Cities like Houston, Orlando and Atlanta would have temperatures very similar to those in Chicago, St. Louis and Detroit. The massive warm-up would not reach northern ND, MN, WI or the Upper Peninsula of Michigan, although a forecast 240 hours out is not nearly written in stone.
