Indianapolis is starting Friday with cool temperatures in the low-to-mid 50s, light northeast winds and a mix of clouds and sun. The afternoon should warm to around 70 degrees, giving the city a calmer finish to a gray stretch of weather.

The latest outlook from the National Weather Service keeps rain chances near zero for Friday, although clouds may thicken at times later in the day. Friday night will be mostly cloudy, with temperatures dipping to around 52 degrees.

Sunny Weekend Brings A Fall Preview

Saturday looks like the weekend standout, with sunny skies and a high near 73 degrees. Sunday should be similarly pleasant, reaching about 74 degrees under mostly sunny skies, while overnight lows settle near 50 to 51 degrees.

Monday stays sunny with a high near 73, making the next several days favorable for walks, outdoor events and general attempts to avoid thinking about winter. Northeast winds will remain light through the weekend.

Rain Chances Return Tuesday Night

Tuesday should be sunny and warmer, with a high near 75, but the pattern turns wetter after dark. Showers could develop after 2 a.m. Wednesday, followed by a 50% chance of showers and thunderstorms during the day Wednesday and a 40% chance of rain showers Thursday.

The updated forecast keeps the bright weekend trend described in Thursday's Hoodline forecast, while extending the unsettled period later next week. No watches, warnings or advisories are currently in effect for Indianapolis.
