If you thought early last week was chilly, just you wait until the middle of this week! While we'll enjoy the middle 80s this afternoon a very strong cold front is looming across the northern Plains. This front will sweep through late tonight and because there is little moisture associated with it there is only a slight chance of a shower or thunderstorm. While this will cool us Tuesday afternoon by about 15° from today's high, a stronger front will come down Wednesday. This will be accompanied by a very strong area of high pressure with an air mass that has originated from far northern Canada. Winds will remain from the north/northeast Wednesday and temperatures for both Wednesday, Thursday and Friday will be in the low 60s; with Thursday being the coldest.
To add insult to injury overnight lows will fall into the upper 30s/low 40s. I feel the best night for us to reach the upper 30s will be Thursday night as the center of the high settles in overhead and our winds will likely calm - setting up a very good scenario for radiational cooling. Although I wouldn't be surprised if some of the more outlying rural areas on Wednesday night maybe squeeze out a 38° or 39°. These cool temperatures could lead to the potential development of frost!
