Indianapolis 2011 Summer Records Discussion

[Chicago WX]

The streak of high temps of 90º+ is at 10 days for Indianapolis, through yesterday. Question is, how long will the streak last? I figured I would start the bidding at 13 days.

FYI, the longest 90º+ streak in history for Indianapolis is 19 (August 8-26, 1936).

[Chicago WX]

Update: 12 and counting through yesterday. 7 more to tie the record, 8 to break it.

Well, unless the clouds move out or burn off I don't think 90 will be reached today. Though we are at 85 as of 10am..

Tomorrow may be another close call but assuming it makes it, then I see no reason why it wouldn't last until at least midweek. There's another chance of storms at that time so who knows what happens then.

The streak would have to go until August 4 to tie.

[Hoosier]

Only 87 at IND as of 2 PM. Still time to make it to 90 but this might be the biggest threat to the streak that we've seen.

That's why I voted for 13 days. I thought today would be close. I've got a feeling it's gonna make it though, and if it does, it's hard to tell how long it will keep running.

Yeah, decent amount of clouds around and visible satellite suggests it may be like that for the rest of the afternoon.

I know the hourly obs have only reached 87, but the web story has been updated to say the streak is now 14 days. I guess we'll see when the climate goes out at 4:30 or so:

Hmm, 4 PM ob is 88. I wonder when the 90 could have occurred.

[Hoosier]

lol...IND hit 90 at 1:21 despite 1 PM and 2 PM obs of 87. Maybe it's just meant to be.

EDIT: If it hit 90, how is this possible?

89 now. Hopefully it hits 90 in the next hour or so or else I'm going to have some doubt about the legitimacy of the streak.

All the local media outlets reporting IND hit 90

Oy, I'm not sure I ever noticed that. I thought the time given in the climate report was whatever time you happened to be on then. So that would mean that LST=EST when we turn the clocks back?

3 PM ob was 87 so there was still a 3 degree intrahour bump...what are the odds of it coming on a day when the streak hung in the balance.

Because the high was set at 1:21 PM Local Apparent Sidereal Time (LST), the 6-hour max was reported at 1:51 PM Eastern Daylight Time (EDT). Look at the Climo report again... it says temperatures are reported in LST. I have no idea what time LST translates to in EDT... but apparently it's based on the solar day, so it's probably closer to 3 PM EDT.

No, I think it's LST = Local Apparent Sidereal Time. So it's based on the sun. Noon LST is whenever the sun is exactly halfway between sunrise and sunset at that location.

Yes. that's correct. For climate purposes, the 24 hour day in daylight time is 1am-1am.

Or we could let the meteorologist from KIND confirm it...unless you missed his post.

That would mean that 12:00 LST would be 12:51 PM EST (or 1:51 PM EDT) at IND today. Let's make things more confusing!

[Hoosier]

Anyhow, I think it probably ends mid or late week. I will go with a tie of 19.

[Chicago WX]

92º was the high at IND today, despite no hourly obs in the 90's. This July just seems to overachieve in every way down there.

Streak is up to 15 days now. No real end in sight it seems with temps forecasted to be around AOA 90º for at least the next seven days.

For meteorological summer...IND is sitting at 77.9º through July 31. The record hottest summer is 78.6º set back in 1874. To break the record, my rough math says IND needs an average temperature of 80.1º or greater in August. There have been two Augusts that have had an average temp of 80.1º or better. Added another question asking if 2011 will be the hottest summer on record at IND.

Cincinnati has also had 15 straight 90+ days. This is the second longest streak on record. The record is 17, set in 1901. The forecast calls for at least four more days of 90+ so the record should be broken.
