Through tonight

89'd today. Temps stopped rising early after reaching 89 at 3pm, even with little cloud cover.

After topping 89 at 1pm, temps crashed down to 86 the next hour. Too early in the day for that to happen already.

89'd here today

Another of meteorological summer, another month of relentless rain for 2025 (especially some days of biblical rainfall)

Finished the month with 6.21" of rain for this June, just 0.45" away from reaching the top 10 wettest Junes on record. Top 10 Wettest Junes (DAY) 1. 10.59" - 1958 2. 9.54" - 1980 3. 9.09" - 1903 4. 7.88" - 2015 5. 7.59" - 1924 6. 7.43" - 2017 7. 7.32" - 1902 8. 7.22" - 1932 9. 7.13" - 1928 10. 6.66" - 1986

After 7 straight days of 90s, the heat wave is over

It begins today for some. Got the first 90 of the year here.

First 90 of the year today. Cincinnati and Columbus didn't, though the latter got 89'd.

Another consecutive wet month in the making.... Wettest year on record coming soon for many by the time Winter comes, even though we're barely halfway through 2025.

Had a streak of wet months since February here, so this month looks to continue the stretch. The last dry month was back in January.

Going to be a long crappy Father's Day weekend for many

July will be rockin'

Looking real active for Father's Day weekend for many https://x.com/skydrama/status/1932062862060437972

Scott Sabol has some sort of "What went wrong?" writeup regarding this Spring https://sabolscience.blogspot.com/2025/05/why-has-spring-been-so-wetcool.html?m=1

Like June 2023?

First month of meteorological summer is near. Looks like we virtually start up warm after the month begins, but it looks to be a head-fake as it goes downhill again by the end of next week.

Garbage over the next couple days starting tomorrow, but a slow warm-up by next weekend to end the month.

From IND's Long Term: .Next week... The overall weather pattern begins to shift next week as the upper jet becomes more west-southwesterly aloft and the storm track lifts northward into Indiana. Closer to the surface, high pressure begins to lose its influence over the state as a developing area of low pressure in the Plains and associated frontal boundaries lift northward into Indiana. Low pressure is expected to ride along the warm front extending over the Ohio Valley and provide perhaps the best opportunity for more widespread rain and embedded thunderstorms Monday night through Tuesday. The focus for greatest convective coverage will again be over southern counties in closest proximity to the warm front and track of the surface low. By Wednesday, an upper low will be in place over the Upper Great Lakes while Indiana is in in the wake of the passing surface low to the east. While it is difficult to forecast subtle waves within the upper jet this far out, this pattern would support continued mostly cloudy conditions with showers as weak waves rotate around the upper low to the north. Keeping the forecast more pessimistic mid week based on the overall weather pattern. Confidence decreases mid to late next week and into the following weekend as some longer range models have been consistent in showing another cut off low pattern developing. Guidance usually struggles with patterns featuring weakly forced systems, so confidence remains low in the finer details this far out. For now, keeping a close eye on the potentially cool and wet pattern going into early June as any warm up back to normal may be fairly brief. Should the forecast pan out with highs remaining below 70 through at least Tuesday here at Indy, this would mark a consecutive string of 8 straight days of sub-70 degree weather extending back to this past Tuesday 5/20. The last time Indianapolis experienced this for such a long period of time this late in the Spring was from 5/25 to 6/2 in 1889. The search for a return to more persistent warmth likely is still 7-8 days out and possibly beyond with 80s likely to return by early in the week of June 2. Yep, another cutoff low in the middle of next week heading into the first week of June. So far, DAY and CMH have had 15 days with measurable rainfall for this month as of yesterday. It will add up a bit next week. The record for most days with measurable rainfall for DAY is 21 days in May 2003 while CMH's record is 22 days in May 2004. Could be creeping toward the record by the end of next week.
