Cedar Rapids has set a new record, hitting 93º at 3pm.

Update:  Cedar Rapids topped out at 94º.

Wow! Very impressive reading. Breaks the daily record by 3F. Dating to 1893, only one year had a later reading of 94F or better - 1997, when it reached 94F on October 3. Obviously, that means had it reached that temperature on tomorrow's date, it would have tied a monthly record for October.

[TheClimateChanger]

Also, looking at the table, only 10 days have ever reached or exceeded 90F at Cedar Rapids in the month of October: October 1, 1976 (90F); October 1, 1897 (90F); October 2, 1953 (92F); October 3, 1997 (94F); October 3, 2006 (90F); October 3, 1897 (90F); October 4, 1938 (91F); October 4, 1897 (90F); October 6, 1963 (92F); and October 10, 1962 (90F). Three of those dates were in 1897, so only 8 unique years since 1893.

While 94F seems unlikely at KCID tomorrow, 90F is certainly possible. Fairly rarified air for October, should it reach that temperature. Would be only the 11th 90+ day on record in October, and 9th year to reach 90F or better in the month of October (and first since 2006).

Per Maximiliano Herrara on X, the Iowa state record high for October is 97F. I saw a couple sites reached that today on the state roundup and he indicated temperatures as high as 99F may have occurred near the Nebraska border.

It's 75F here on an October midnight. I've never seen that before. 75F at midnight in the summer is even rare.

Climate is warming. Faster than we think.

Yep I saw 92 also, looks like summer is trying to fight back lol

Edit: not sure why we are posting this in the September thread 

Looks like Minneapolis did indeed reach 92 yesterday. Could double our all time number or October 90 degree days if we hit it again today.

Community Notes: To date, it has been the 11th warmest year on record at DTW (out of 150 years). Prior to 2006, only 4 warmer starts to a year were observed (1921, 1998, 1991, and 1955). In the 117 years from 1874 to 1990, only 2 years were warmer (1921 & 1955).

I mean those are some huge departures and we are going into mod to strong El Nino winter which isn't almost certainly going to be above normal maybe significantly above normal.

I know Jan & Feb were huge departures, thats why I said thats why its the 11th warmest year thru Oct 1st. Last winter was a great example of how even in the mildest winters (7th mildest winter on record last year) we can get plenty of winter storms. In fact, I cant recall a more destructive winter for trees than last year. So honestly, no idea what to expect this winter. Id bet money its colder than last winter. But storm tracks/precip trends are far more important for snow-lovers than temps are in this region. (Of course, for us "deep winter" fans of snowcover and cold in addition to snowfall, the colder the better). Waiting for the NMME model consensus update for Oct, but the last run was surprisingly tame for a stronger el nino winter (DJF departure approx +0.5C).

Last Saturday, September 30th I went up to the Wisconsin Rapids area for some railfanning. I neglected to check the forecast, assuming the forecast of sunny for Madison also applied to the rest of Wisconsin. Instead, thunderstorms moved in just as I was arriving, and lingered through the early afternoon. Me and my cameras got drenched, and it took until the mid-afternoon to finally get some nice sun-lit train shots. Consolation prize...
