Sunshine will prevail this morning as a wedge of dry air wraps in on the backside of a very strong area of low pressure that continues to spin through the upper Great Lakes. The low currently sits in Minnesota where rain showers and gusty winds will be found. Closer to home winds will be gusty at times from the west which will help keep a bit of a chill in the air for this afternoon. After yesterday's high of 77° we'll sit at about 70° for today.
The surface low will continue to move east through today and tomorrow but the upper level low will eventually become cut-off from the main jet stream later tonight and tomorrow. As this happens, it will actually begin to move back into southern Wisconsin as a blocking high holds tight in the Atlantic. At the same time the jet stream will build north in the west causing temperatures to rise into the upper 80s. And as the old saying goes, "what goes up, must come down" the cut-off low in the Great Lakes will continue to pull cool air southward and keep temperatures in the low 60s for us. In fact, it doesn't appear as if the low will be in any hurry to depart and will stick around through the weekend.
