Everyone knows July 1936 was exceptional hot for most reading. But I didn't know it held the HI record for DSM ( kept since 1936). One would think it would be more recent with UHI and more water vapor in the air especially compared to the 1930's.
So I went and looked at 7/25/1936 and found the High temp for DSM was 110F (all time high for the DSM area tied with Aug 4, 1918)
and the low for the date was 76F. but to have a HI of 122- assuming it occurred with 110F temp would mean a sultry 71.5F F dewpoint as shown which many think did not happen in July of 1936 in the plains. Well it did that day. It surprised me.
Yeah, the ensembles were trending warmer for that time period, but seem to be leveling off around the low 90s for the west side.
The GFS always has a few members that skyrocket into the blowtorch zone, and it's nerve-wracking when the operational is one of them.
Since 1936-- the 84 dewpoint that was recorded in between hours/ metars/ (that is where the time consuming work is done) is from my research the new record. Old record was 82 in 2001.
Today felt cool compared to Sundays horrific heat n humidity!
Mby had 2 thundershowers with .19" which kept the numbers down slightly.
Temp 94.6
Dewpoint 84.0
Heat index 121.0
Its unbelievable to say but it felt better than Sunday!
