Our string of sunshine and unseasonably warm weather continues in the week ahead. Sunday was the third day in a row of 80 degree highs, and we may tack on another two or three days in the 80s between now and Thursday.
Tonight and Monday: Another clear, pleasant evening is on tap as temperatures gradually cool into the lower and middle 50s by Monday morning. Abundant sun quickly pushes temperatures into the 70s by midday tomorrow and highs near 80 degrees again.
A weak cold front moves in Tuesday, but likely will not have enough moisture to trigger showers. However, it may have just enough northerly flow behind it to push lows back into the 40s and lower 50s Wednesday morning.
Clouds may increase late Wednesday but not before highs make another run at 80 degrees. Thursday will be a day of transition with the arrival of a cold front. Highs will remain mild in the 70s, but showers and storms increase.
We’ll be back to reality behind this front with temperatures 30 degrees colder next weekend than this past Saturday and Sunday… with highs near 60 and patchy frost possible Sunday morning. Have a great evening – Sean Ash
What a way to bring in autumn! After the chilly start this morning temperatures are responding nicely to 100% sunshine across central Indiana.
This Afternoon: We’re already in the 60s at this hour and highs will be climb into the lower and mid 70s… closer to the average high of 75. Note that the record for this date was set just 4 years ago at 94! No 90s in the forecast but there is a warming trend heading into the weekend.
Evening and Overnight: Expect another pleasant evening with clear, calm conditions and temperatures slowly dropping into the 50s by 10pm. Seasonably chilly lows again tonight in the 45 to near 50 degree range.
Wednesday: In typical fall fashion we’ll see a rapid rise after the chilly start tomorrow morning. Temperatures will be near 70 by midday and upper 70s in the afternoon. Air mass modification leads to warmer highs in the days to come and we’ll near 80 degrees as early as Friday.
Thanks to a blanket of high pressure over the Ohio Valley we don’t see rainfall in the forecast until early-middle of next week. Between now and then we’ll bask in sun and enjoy cool nights and warming afternoons. This is truly a fantastic way to start the autumn season.

35 to 45mph gusts have taken some of the luster out of a pleasant Sunday in central Indiana. Gradient and thermal wind gusts remain formidable at this hour but will weaken as the sun sets and an area of low pressure in the Great Lakes moves east. Afternoon temperatures are running 5 to 15 degrees cooler than 24 hours ago due to the passage of a cold front overnight.
Afternoon temperatures are running 5 to 15 degrees cooler than 24 hours ago due to the passage of a cold front overnight. A secondary cold front is crossing south of I-70 now and knocks temperatures into the upper 50s and low 60s this evening. There’s just enough upper level lift to support a very narrow band of quick-moving sprinkles and showers north of Indy early this evening. They are diving east-southeast rapidly but most should weaken before arriving in Indy and points south.
Tonight: The northwesterly breeze weakens overnight, but remains in the 5 to 15mph range. This wind should be enough to prevent much dense fog from developing. Kids will need the jackets tomorrow morning with lows in the mid to lower 40s. But expect a good dose of sunshine into midday with a slow climb to 60 by 12pm.
Monday: Cool Canadian high pressure delivers decent sunshine Monday, but scattered clouds and a decent breeze build during the afternoon. High temperatures will be near 10 degrees below average in the mid to upper 60s. The Autumnal Equinox arrives Monday evening at 10:29pm EDT and it will feel like it for a few days.
The rest of the week is highlighted by a string of sunshine courtesy of a blocking high pressure system aloft. This will pancake across the Ohio Valley and deliver comfortable nights, mild afternoons and a mostly clear sky. As noted in earlier forecasts, rainfall the next ten days will be rather slim due to this pattern developing. We’re expecting above normal temperatures to finish the week and the month of September. This warm trend may very well carry over into the beginning of October. Have a great evening – Sean Ash
Sunny and afternoon temperatures in the 70s can be defined as weather perfection for some. That’s the case in central Indiana today with a pleasant southeast breeze to boot.
This paves the way for the best weather during Operation Football of the season. Kickoff temperatures will be near 70 and expect a slow cool down to near 60 during the fourth quarter.
Tonight: Another clear and comfortable night ahead as low temperatures eventually drop into the middle 50s.
Saturday: We’re still on target for the warmest day of the week tomorrow. A southwest wind and sunshine push highs into the 80s during the afternoon. Daylight hours Saturday will be dry but shower and storm chances ramp up toward or just after sunset.
Though there is a Slight Risk of severe weather for the far northwestern corner of the state, we believe any storms locally will weaken after sunset. Lightning and local downpours will be the main storm threats Saturday night. At the time of this posting we’re bracketing the hours of 7pm to 7am as the rain/storm window in central Indiana.
Sunday: Showers are likely by midnight tomorrow night and during the predawn hours of Sunday. Latest guidance continues to suggest that much of Sunday will be dry as a northwest wind develops.
After some early morning showers and clouds, expect a decrease in cloud cover during the afternoon with cooler highs in low to mid 70s.
That will be our one and only chance of rain over the next 10 days. After a brief cool down Monday and Tuesday, temperatures warm to more seasonal levels during the second half of next week. Have a great evening – Sean Ash
Our beautiful fall-like weather continues and today we’re dealing with less cloud cover than the past few days. The brighter sky leads to warmer temperatures and this is the first official 70 degree day in Indianapolis since last Thursday. Highs will range from 70 to 75 and mark the advertised warm up heading into the weekend.
Tonight: If you have outdoor evening plans the weather remains spectacular. Expect a slow cool down into the 60s by 8pm. Keep the windows open tonight with comfortable lows in the upper 40s and lower 50s. Though patchy fog is possible in river valleys and low-lying areas, we don’t anticipate major problems Friday morning.
Friday: I’m not a doctor but with sunshine and mid to upper 70s expected Friday, you have my permission to make it a three day weekend! We’ve got all the ingredients in place for the best night of Operation Football weather this season Friday evening. Expect kickoff temperatures in the lower 70s with a bright sky. You might want to pack a light jacket as fourth quarter temperatures drop into the 40s.
This Weekend: We’re still targeting Saturday as our warmest day this week and quite possibly for some time. Under a bright sky and with a southwest wind highs will easily top 80 degrees. Daylight hours should be rain-free, though we may need to add a chance for the northern viewing area if a front gets closer than anticipated. Saturday night and early Sunday there is a chance of showers and storms along the cold front. It should be noted that latest model guidance shows lower rain potential and a quicker front departure.
Providing this verifies, Sunday afternoon may be mostly dry. This looks to be our only chance of rain for nearly 10 days. Canadian high pressure promptly spreads in across the Ohio Valley after this front and blankets the region for much of next week… resulting in several days of sunshine and comfortable conditions.
Though cooler, model guidance isn’t as bullish on much below normal air as prior runs. So I’ve relaxed the chill and pushed highs to more seasonal levels in the 70s next week. Regardless it should be fantastic fall weather to bring in autumn!
Have a great evening – Sean Ash
