Daily Weather Brief for 25 May 2026: Patchy Morning Fog Gives Way to a Mild Indianapolis Memorial Day
National Weather Service guidance points to early patchy fog, mostly sunny skies and highs near 79 in Indianapolis before rain chances increase later in the week.
INDIANAPOLIS | Indianapolis begins Memorial Day with patchy fog before conditions turn mostly sunny and mild through the day.
The National Weather Service forecast for Indianapolis calls for patchy fog before 9 a.m., then mostly sunny skies with a high near 79. Winds are expected to be calm early before becoming east northeast around 5 to 7 mph during the morning.
That means the earlier draft language calling for mid-80s temperatures and afternoon thunderstorms should be corrected for today’s Indianapolis forecast. Thunderstorm chances are more relevant later in the forecast period, with rain and storm chances increasing Tuesday night into Wednesday if the current forecast holds.
For Memorial Day plans, the main morning issue is visibility in areas of fog. Drivers should allow extra space, use headlights where visibility is reduced and watch for changing conditions near low-lying areas, river corridors and open fields.
The afternoon should be more favorable for outdoor events than the original storm-focused wording suggested. Residents should still check updated forecasts before evening travel, but the day’s primary Indianapolis message is mild, mostly sunny weather after early fog.
