They were at 92 at 1pm, and only managed 1 more degree lol. That with zero clouds, unlike the prior heat spell that had numerous cu popping up by noon. Looks like some weakening Iowa slopping seconds tomorrow night, and then on Sunday the best convection will fire east of the cwa. #2018 Link to comment Share on other sites More sharing options...

It is harder to pull off around here since there aren't corn fields across the street. First 80 degree dew I've felt since my days in LAF. Link to comment Share on other sites More sharing options...

Was walking across a large parking lot earlier, and the temp above that asphalt had to be over 100. That combined with the dews which were close to 80 made it almost hard to breathe. Heat index was probably well over 120 at that spot. Link to comment Share on other sites More sharing options...

I was able to feel the clammy skin starting even after just a few minutes of standing around. Somebody had just gone outside to mow their grass when I was out. They are going to be mowing in the dark lol Link to comment Share on other sites More sharing options...
Hoosier Posted June 30, 2018 Author Share Posted June 30, 2018 7 hours ago, Hoosier said: Are you on board with an 80 degree low at ORD tonight? I still think it is more likely than not, and have noticed that the models have a tendency to drop temps in the city too quickly. The HRRR gets it down to about 78, even with a ~7 degree drop between 7 and 9 pm tonight, which is unlikely to happen. As expected, actual drop from 7-9 pm: 4 degrees Link to comment Share on other sites More sharing options...

Hoosier Posted June 30, 2018 Author Share Posted June 30, 2018 brutal Area Forecast Discussion National Weather Service Chicago/Romeoville, IL 928 PM CDT Fri Jun 29 2018 .UPDATE... 928 PM CDT No real changes planned to going forecast. Chicago Midway`s heat index is still sitting at 104 after 9 pm. It is this nighttime heat that doesn`t allow the body to recover from the stress from the intense daytime heat that poses the most significant danger during heat waves. It looks as though the heart of the city of Chicago will see heat indices at or above 100 until around midnight and probably won`t drop below 90 all night. Anyone without access to a/c in the city should consider spending time in air conditioning at times this weekend to lessen the risk from this heat wave. - Izzi Link to comment Share on other sites More sharing options...

The rate of descent has slowed to about a degree per hour. About 7 hours of cooling potential remaining so will need at least an hour or two where it doesn't drop to have lows of 80+.

That site is basically right in the middle of a corn field though, so 82 is definitely believable. Link to comment Share on other sites More sharing options...

Hoosier Posted June 30, 2018 Author Share Posted June 30, 2018 ORD/MDW have had the same hourly temps for several hours. Both 83 and have been dropping a degree per hour for the last 4 hours. Going to need an hourly hang up at some point to not drop below 80. Link to comment Share on other sites More sharing options...
cyclone77 Posted June 30, 2018 Share Posted June 30, 2018 As of 5am MSP has only dropped to 83. Heat index still 88. Looks like ORD stayed above 80, as they're still 81 atm. Link to comment Share on other sites More sharing options...
michsnowfreak Posted June 30, 2018 Share Posted June 30, 2018 While it is not interesting to me as snow and other Winter weather data, I have looked up quite a bit of heat data from the past. Sometimes it was a drier heat and sometimes it was humid, but the heatwaves that we had in the 1930s, 40s and 50s seemed worse and more numerous than what we typically get today. Again I'd have to look up humidity levels which is not always easy to do, but based not just the actual weather data but reading newspaper articles (I subscribe to the free press archives so I can see any daily newspaper since 1837) Some of the heat waves back then were extremely deadly as well as very uncomfortable. The heat waves of July 1936 and August/September 1953 were probably THE most brutal, however the month of July 1955 was almost nonstop searing heat. When you are looking up past weather data if you do not have access to do points or humidity levels, an easy way to get an idea of whether it was humid or dry heat is to look at the low. If it says Hi 95ﾟ low 62ﾟ chances are it was a drier heat. If it says Hi 95ﾟ low 76ﾟ, chances are it was very humid. I honestly dont know how they survived without AC.

michsnowfreak Posted June 30, 2018 Share Posted June 30, 2018 Low was 76 at DTW. Detroit averages 11 days per year with a low temp of 70F+. The most was 29 days in 1995. Only twice on record (1967 & 1992) did we go the entire year without a 70F+ low. The warmest low on record was 80F and it happened 5 times: 1921, 1927, 1931, 1942, 2006.

A week straight of mid 90s in Buffalo is something I've never seen in my lifetime. We have the potential to hit 100 for the first time in history tomorrow.

King James Posted June 30, 2018 Share Posted June 30, 2018 How do these dew points work today? Is it a bit like the temp where if it’s a warmer start you can get higher of a temp than the day before. Cause right now the dew here is already 73. We didn’t make it to 80 yesterday but we also didn’t start out at 73. Anyway, stay cool boys . Link to comment Share on other sites More sharing options...
