An approaching front is expected to stall out in or near the southern part of the state, and this will bring a slight chance of a shower or thunderstorm during the morning through the early afternoon hours. The front may creep ever-so-slowly southward reducing the rain chances for the remainder of the on-track time. Expect a mix of sun and clouds, with winds continuing to be breezy out of the southwest at 10-15 MPH with gust up to 25 MPH possible at times. 10AM temps will be in the lower 70s, and the high will top out around 82 degrees. Chance of rain before 2PM is 30%.
The stalled front will be forced northward during the day on Friday, bringing an increased chance of showers and storms especially during the late afternoon. It will be a mostly cloudy day with much calmer winds starting off out of the northeast and shifting to out of the east-southeast by late afternoon. Temperatures start off in the upper 60s at 10AM, and warming to near 78 for the high. Rain chances are low before 2PM, around 20%, but increase after that to 50%.
A low pressure center will be moving across the upper midwest on Saturday continuing to force the ever-so-slow moving front northward across Central Indiana on Saturday, and will drag a trailing cold front across the area on Sunday. Shower and storm chances appear to be likely throughout the day on Saturday, with rain totals of 1/2 inch possible. Not saying that Saturday is going to be a complete washout, but on-track activities may be halted a few times. Sunday's rain chances are a little lower for "Pole Day," but only slightly. Another day that will have stoppages, but not a complete washout. Saturday's high will be around 81, with Sunday's high cooler, around 75.
