Record warmth through much of this week
A very persistent weather pattern will continue to keep temperatures much warmer than normal through the entirety of this week. There will be some changes later this week as a storm system moves across the upper Midwest, which will at least bring a little rain to the region. The storm currently over the west coast will be the responsible party for rain, cooler air, and maybe even a few snowflakes late in the week to weekend.
Meanwhile, temperatures will top out around and above 50° again Tuesday, Wednesday, and Thursday before turning cooler Friday. In the wake of that storm system, cooler air will move in Friday and linger through the weekend to middle of next week.
Even with the cooler air and drop in temperature from Friday onward, daily high temperatures look to stay about 10 degrees above normal for mid-February. Still, the change will be noticeable and it looks like we’ll take an extended break from record-level warmth after Thursday.
