The synoptic setup for the rest of the forecast period remains the same: a cold front passed through today, which will bring west to northwesterly winds to the region for tomorrow, resulting in cooler overall temperatures. A low pressure surface trough will approach central Indiana on Thursday from the north, bringing a chance for scattered showers in the afternoon. Rainfall totals are expected under a tenth of an inch, but still could disrupt some of the scheduled on track sessions. Behind the trough, high pressure will build in, causing surface winds largely from the north to northwest, continuing to cool temperatures with a morning low in the mid 40's °F and a high in the mid 50's °F.
The area of high pressure is anticipated to move over or close to the Indianapolis region, resulting in calm and variable winds during Saturday morning, with winds then shifting to the south to southwest in the afternoon as the system continues eastward. Saturday night, a warm front extending from a low pressure system to the west will pass through the area, causing Sunday's low temperatures to remain relatively unchanged from the previous day's high. Southwesterly winds behind the warm front and ahead of the pairing cold front will allow temperatures to warm a few degrees before cooling again as the cold front passes through. Both mentioned fronts could bring a chance for precipitation on Sunday, especially in the morning, however rainfall totals will be largely determined by the location of the surface low's center.
