We've enjoyed the influence of high pressure over the last couple of day, as the ridge provided plenty of sunshine and somewhat seasonally cool temperatures.  As a protective dome of stable air eases off to our East, we'll notice a return flow of Southerly breezes begin to boost our temperatures.  Inland locations will easily top 80 degrees, though it will remain cooler near Lake Michigan.  A warm front lifts to our North tonight and tomorrow sending readings rising even more and placing us in the "warm sector." That means toasty temperatures will be accompanied by higher humidity with climbing dew points.  The position of this warm front is critical to our forecast, as it becomes the focal point for showers and storms.  Computer models continue to be different in their placement of the front.  Suffice it to say that our chances for showers and thunderstorms increase Friday and as we approach and go through the weekend, though there will be many dry hours each day as well.
