    WHY is your 7 day forecast so VASTLY different than both the “regional forecast” and your own weather blog? All last week your 7 day forecast put us in the 70’s. The regional forecast, which was accurate, had us in the 40-50’s. I am frustrated because I’ve always used the 7 day forecast to dress my kids for school and plan my work outfits for the week. It wasn’t even CLOSE (oh, and by the way, according to your 7 day forecast…It’s going to be 70 today!!! Yes! oh, wait, never mind. Let’s look at the regional… *sigh*)

    Get it together, would you?

    It was mentioned on air and on the Weather Blog that a frontal boundary would be nearly stationary near the Wisconsin-Illinois border. If the boundary were to stall out just 50 to 100 miles further north or south, the going forecast would change. North of the boundary, our wind would be out of the east-northeast and have a cool, moist (cloudy) flow off Lake Michigan. South of the boundary, wind would be out of the southeast, thus warming up temperatures. These kind of scenarios are very tricky to forecast. All models we use indicated that we’d be on the warm side; but I made sure I mentioned what else could happen. And sure enough, Mother Nature gave us a northeasterly flow today.

    Here’s the blog post if you’d like more information:
