INDIANAPOLIS | Central Indiana gets a quieter Juneteenth forecast Friday, with sunshine, comfortable temperatures and no hazardous weather expected today or tonight, according to the National Weather Service in Indianapolis. The calmer weather will not last all weekend, however, as widespread rain, thunderstorms and a renewed flooding risk are expected Sunday into Sunday night.
Friday / Juneteenth
Indianapolis should be sunny Friday with a high near 78°F. Winds will be light early, becoming west-northwest at 5 to 9 mph during the morning.
Friday night should be partly cloudy with a low around 60°F. West-northwest winds of 5 to 7 mph should become calm during the evening.
The National Weather Service Hazardous Weather Outlook says no hazardous weather is expected for central Indiana today or tonight. That means CGN News is not treating Friday as a separate Severe Weather Alert day.
Saturday
Saturday should remain mostly sunny with a high near 80°F. Light west-southwest winds should become west at 5 to 9 mph during the morning.
Saturday night should be partly cloudy with a low around 62°F. Winds should become calm during the evening.
For outdoor events, travel, yard work and local Juneteenth weekend plans, Friday and Saturday remain the best weather windows before a more active pattern returns.
Sunday
The next weather concern arrives Sunday. The forecast calls for a slight chance of showers early, followed by showers and possibly a thunderstorm after 2 p.m.
Sunday’s high should reach about 78°F. South-southeast winds should remain light at 3 to 8 mph, but rainfall chances rise sharply during the afternoon. The National Weather Service forecast gives Sunday an 80% chance of precipitation, with new rainfall amounts between one-quarter and one-half inch possible during the day.
Sunday night is the period to watch most closely. Showers and possibly a thunderstorm are expected, and some storms could produce heavy rainfall. The low should be around 65°F, with south-southeast winds near 13 mph and gusts as high as 25 mph. Rainfall of 1 to 2 inches is possible Sunday night, with locally higher amounts possible in storms.
Flood warning information
Existing flood warnings remain in effect for parts of Indiana rivers after earlier rainfall of 1.5 to 4 inches across much of the area. The National Weather Service reported minor lowland flooding in portions of the White River, East Fork White River and Wabash River basins.
Warnings include locations along the White River at Elliston and Hazleton, the East Fork White River at Seymour, and several Wabash River points including Covington, Montezuma, Terre Haute, Hutsonville and Riverton. Minor flooding is either occurring or forecast at several of those points.
Moderate to heavy rainfall expected Sunday into Monday may extend or redevelop flooding in some areas. People near flood-prone roads, river bottoms, agricultural land, low-water crossings and drainage areas should monitor official river forecasts through the weekend.
Monday
Showers and possibly a thunderstorm are expected Monday morning, followed by a chance of additional showers and thunderstorms after 8 a.m. Monday’s high should be near 76°F.
North winds around 11 mph may gust as high as 21 mph. The chance of precipitation is 80%.
Monday night should be mostly cloudy with a low around 57°F. North-northeast winds should run 5 to 9 mph.
Tuesday through Thursday
Tuesday should turn mostly sunny with a high near 77°F and a low around 59°F Tuesday night.
Wednesday should be mostly sunny with a 20% chance of showers and thunderstorms and a high near 79°F. Wednesday night carries a 20% chance of showers and thunderstorms with a low around 61°F.
Thursday also carries a 20% chance of showers and thunderstorms, but the day should otherwise be mostly sunny with a high near 79°F.
Travel and outdoor planning
Friday and Saturday are the strongest outdoor-planning days for Indianapolis and much of central Indiana. Conditions should be mild, bright and manageable for ceremonies, parks, road trips and evening events.
Sunday afternoon through Monday morning is the trouble period. Rain, thunderstorms, ponding water, reduced visibility and renewed river flooding may affect travel. Anyone with outdoor plans Sunday should have an indoor backup and check the forecast again before leaving.
Safety
Do not drive through water covering a road. Floodwater may be deeper than it appears, and pavement can be damaged or washed out below the surface.
Move indoors when thunder is heard. Lightning can strike even when rain is not yet heavy at your location.
This forecast may change as the Sunday system develops. Use current National Weather Service watches, warnings, advisories and river statements for immediate decisions.
