Indianapolis, IN
Mild and damp Christmas then a warmer weekend | Dec. 25, 2025
TODAY
Christmas morning starts gray with widespread dense fog, and visibility can drop quickly on highways and ramps, especially before sunrise. A little patchy drizzle is possible late morning into early afternoon, otherwise it stays cloudy with temperatures slipping into the lower 50s. Winds stay light early, then turn north northeast around 5 mph, so travel is mainly fine once the fog lifts, just keep extra stopping distance on damp roads.
TONIGHT
Clouds stay locked in and rain becomes likely late, mainly after 1am. Lows settle in the mid 40s, with an east breeze around 5 to 10 mph. If you are driving home late from Christmas gatherings, plan for wet pavement and a few pockets of fog in the usual low spots.
TOMORROW
Rain is likely in the morning, then becomes more scattered midday and afternoon, with patchy fog possible into early afternoon. Highs jump into the low to mid 60s, with a southeast wind around 10 mph shifting west later, gusts up to 20 mph. It is a mild day for late December, but the morning commute and airport runs could be slow with low clouds, wet roads, and reduced visibility at times.
TOMORROW NIGHT
Mostly cloudy and mild, lows in the low to mid 40s, with a light west northwest breeze around 5 mph becoming nearly calm at times. Roads stay mainly wet to dry depending on where the showers linger, and travel remains manageable.
SATURDAY
Patchy fog is possible early, then mostly cloudy with some brighter breaks. Highs reach the mid 50s, with a light east southeast breeze around 5 mph. This is a solid travel day, no winter problems, just occasional low visibility early and a lot of cloud cover.
SATURDAY NIGHT
Mostly cloudy with a small rain chance late, lows near 50, with a southeast wind around 5 to 10 mph. If you are heading back home overnight, expect a few damp stretches, but nothing icy.
SUNDAY
A wetter day, with rain becoming more likely into the afternoon and a few rumbles of thunder possible later. Highs land in the mid 60s, with a southwest wind around 10 mph, gusts up to 20 mph. Plan extra time for holiday return travel, heavier rain bands can slow traffic and reduce visibility.
SUNDAY NIGHT
Rain tapers late, then colder air rushes in and a few snowflakes are possible toward daybreak. Temperatures fall into the low 20s, with a west northwest wind around 10 to 15 mph, gusts up to 25 mph. Watch for a few slick spots developing late if roads stay wet as temperatures drop.
7 DAY OUTLOOK
The holiday stretch stays unusually mild and mostly wet rather than snowy, with fog and drizzle concerns first, then warmer air pushing highs into the 50s and 60s through the weekend. The bigger pattern change arrives right after, with a strong turn back to colder, more typical late December weather early next week, including a blustery, much colder Monday and the potential for periodic light snow chances in northwest flow beyond that. Confidence is high on the fog Christmas morning, the mild weekend, and the sharp cooldown after Sunday night, with lower confidence on exactly how quickly rain ends and any brief snow chance flips on late Sunday night.

INDIANAPOLIS (WRTV) — The National Weather Service out of Indianapolis has issued a Heat Advisory for all of Central Indiana and a High Heat Warning for parts of northern Indiana. The Advisory and Warning will go into effect at 12 PM on Monday and will run through 8 PM Thursday.
WRTV
A Heat Advisory means that temperatures in the 90s with dew points in the 70s, will lead to Heat Index values reaching 106. Hot temperatures and high humidity may cause heat illnesses.
Stay cool:
Drink plenty of fluids, check up on relatives and neighbors, and stay in an air-conditioned room when possible. If outside for extended periods of time, make sure to take frequent breaks in the shade as much as you can.
TODAY
Patchy fog early gives way to a partly sunny, warmer, and much less active day. Highs reach the mid to upper 80s, with a light south breeze around 5 mph. After the unsettled Saturday, this looks like a far more usable day for outdoor plans, with most of central Indiana staying dry from start to finish.
TONIGHT
Mostly clear early, then becoming partly to mostly cloudy toward daybreak. Lows hold in the low 70s, with a light south southeast breeze around 5 mph. Humidity stays elevated overnight, but quiet weather continues and there are no meaningful travel concerns.
TOMORROW
Mostly sunny and hot with highs pushing into the low 90s. A south southwest breeze around 5 to 10 mph keeps the air moving, but the bigger story is the heat and humidity building in. Heat index values around or above 100 are possible during the afternoon, so outdoor plans will need extra water and more breaks.
TOMORROW NIGHT
Mostly clear and warm, with lows around the mid 70s and a light south southwest breeze. There will be very little cooling after sunset, and the muggy feel hangs on through the night. Dry weather remains in place.
TUESDAY
Sunny and even hotter, with highs in the low to mid 90s and a light southwest breeze around 5 mph. This is another day where heat becomes the main impact, and it will not take long to feel it during the afternoon. Outdoor work and summer activities will need to be paced carefully.
TUESDAY NIGHT
Clear and warm again, with lows in the mid 70s and a light southwest wind. The air remains sticky overnight, and there is still no meaningful rain signal for Indianapolis.
WEDNESDAY
Mostly sunny and hot, with highs in the low to mid 90s. Wind stays light, becoming south southwest around 5 mph in the afternoon. Heat remains the main concern, and another uncomfortable summer afternoon is expected across central Indiana.
7 DAY FORECAST
After Saturday’s leftover storm chances fade away, the pattern flips quickly toward heat and humidity. Sunday looks quieter and warmer, then Monday through at least Wednesday trend hot with highs in the 90s and heat index values over 100 possible at times. Rain chances stay very low through midweek, with the next better opportunity for showers and storms showing up later Thursday into Friday. Overall, the bigger concern after tonight becomes summer heat rather than repeated storm chances.
