More heat on the way

Another massive heat wave is in the forecast according to the CPC’s outlook, and this time, the region expected to be baked is the northern Plains and Upper Midwest. Curiously, while the northern US roasts, the southern part of the country looks to be well below normal. In the summer, that’s comfortable, so it’s not the story,

Unlike the blocking ridge that brought the heat in the Pacific Northwest last month, this looks like a more traditional ridge allowing all that heat to build. Temperatures from Montana through the Dakotas and into northern Minnesota could hit triple digits through early next week.

There will be a remnant mid and upper level trough over the southern US, which will lead to several rainy days, and keep temperatures cool. If it weren’t for that trough, given the greater jet pattern, a more significant heat wave could have been in store for a bigger population.
