Forecasted conditions remain relatively similar from the initial forecast for the Indianapolis 500 from Monday. Slightly cooler temperatures are expected compared to earlier in the week, with partly cloudy conditions for both Carb Day and race day. Precipitation chances have decreased slightly, though there is still the possibility for isolated showers and thunderstorms during Sunday afternoon.

For Friday, an upper level low pressure trough will move into the region Thursday night into Friday morning. Recent runs of forecast models suggest the trough will center itself to the west of central Indiana, contrasting the output from Monday. The trough's position implies an increase in moisture due to southerly winds aloft, resulting in more partly cloudy conditions. At the surface, an area of high pressure over New England will cause light winds from the east to northeast, though wind direction may be variable at times.

For Sunday, a high pressure system located off the Atlantic coast, coupled with a low pressure system passing through southern Quebec will cause a slight increase in winds from the southwest Saturday night into Sunday, leading to warmer low temperatures Sunday morning. The increased air temperatures, in addition to relatively warm dew point temperatures could result in patchy fog in areas near sunrise, though any fog will be gone within the following few hours. An increase in moisture at the mid-to-low levels of the atmosphere could result in some isolated showers through the region during the afternoon, with an approaching cold front possibly provoking the development of thunderstorms.
