daddylonglegs Posted September 10, 2013 Author Share Posted September 10, 2013 Knocked off another 90F today...winds are west here now. DP lower today. Link to comment Share on other sites More sharing options...
weatherbo Posted September 10, 2013 Share Posted September 10, 2013 Frost for MI? exciting!! DAYTIME TEMPERATURES WILL BE COOL...LIKELY REMAINING IN THE 50S THROUGH THE COURSE OF THE DAY. THIS WILL SET THE STAGE FOR RATHER COOL/COLD TEMPS FRIDAY NIGHT AS SKIES CLEAR OUT AND WINDS DIMINISH. AWAY FROM THE LAKES TEMPS SHOULD EASILY FALL INTO THE 30S...WITH SOME LOCALIZED UPPER 20S NOT OUT OF THE QUESTION...LEADING TO PATCHY-AREAS OF FROST. FROST HEADLINES LOOKING MORE AND MORE LIKELY AS WE GET CLOSER TO THAT FORECAST PERIOD. Link to comment Share on other sites More sharing options...
Geos Posted September 10, 2013 Share Posted September 10, 2013 That Friday map looks so nice! Hit 94.6° here. Already backing down. 59° dew Link to comment Share on other sites More sharing options...
Stebo Posted September 10, 2013 Share Posted September 10, 2013 No record here today unless we somehow manage to pop upward 2 degrees in the next hour, which looks very unlikely. Link to comment Share on other sites More sharing options...

Ottawa Blizzard Posted September 10, 2013 Share Posted September 10, 2013 Really impressive temperature gradient in Ontario today. Up to 92F in Toronto, but only 62F in Ottawa!! Link to comment Share on other sites More sharing options...
Stebo Posted September 10, 2013 Share Posted September 10, 2013 Just something to throw out there since lately people make mention of KDTW being the warmest spot in the entire area, KDTW was one of the coolest spots today almost all of the major local sites were equal to or higher than KDTW's 93.

harrisale Posted September 10, 2013 Share Posted September 10, 2013 Peaked at 33.9C today, about one degree C off the record for today. Still, enjoyed the steaminess one last time this summer. Also since it hasn't been mentioned yet, all of southern Ontario has been put under a slight risk by the SPC for tomorrow. I'll be out chasing what will likely be the last decent set up of the year. Some multicell clusters will likely form ahead of a cold front and bring some decent damaging wind action. Similar setup to July 19th around here.

I was actually going to mention that I was surprised DTW "only" hit 93F compared to some other spots in the area, so figured Id quote your post. It doesnt change how often DTW is one of the warm spots these days, but today that mantra couldnt be further from the truth. DET hit 96F today. The forecast high of 97F was underdone (factoring in the airmass and upstream obs), NAM and RAP way too hot, but GFS MOS and Euro text output were spot on. No record high, but it was the first 90F+ day since July 19th, and the 6th of the year. Link to comment Share on other sites More sharing options...
magoos0728 Posted September 10, 2013 Share Posted September 10, 2013 Hit 96--I have 20 of the toughest students for sticking it out in obnoxious heat today. A rumor went around about 60s on Friday--the good teacher confirmed... Link to comment Share on other sites More sharing options...
OHweather Posted September 10, 2013 Share Posted September 10, 2013 I have a question for those who know more about temperature obs than I do...CLE's daily climo report shows a max of 96 (link)...their record event report shows a max of 96 for CLE (link)...and their observation archive for CLE doesn't show anything higher than 96 (link)...which is very impressive. However, GR:Earth blatently shows a temp of 97 at CLE at 2:51PM. Any idea why there's this discrepancy? I'm assuming here that 96.8 rounds up to 97. Thanks. Just so you can look for yourself and make sure I didn't have the program set to show heat index values instead of ambient temperatures I moved the cursor over CLE so you can see in the text box that 96.8 is in fact the temp in that observation.

Powerball Posted September 10, 2013 Share Posted September 10, 2013 So DTW reached a high of 93*F (despite a stiff SW downsloping wind and absolutely no clouds), 1 degree shy of the record high, yet DET made it all the way to 96*F, surpassing DTW's record high by 2 degrees. Nice. The problem was the dewpoints. They didn't mix out nearly as fast as expected. Link to comment Share on other sites More sharing options...
daddylonglegs Posted September 10, 2013 Author Share Posted September 10, 2013 Oh lord... a band of something green is showing up on the radar, moving this way out of se MN... could it be? rain??? I'm sure it will evaporate before it hits the ground. Still hot here...but lots of clouds now. Link to comment Share on other sites More sharing options...

Stebo Posted September 10, 2013 Share Posted September 10, 2013 KDTW has a radiational cooling issue, not daily high. 70 last night was one of the cooler lows in the area as well, thanks for proving my point. Link to comment Share on other sites More sharing options...

Thought you'd post about the risk here sooner or later. I wouldn't say that the risk will be as robust as July 19th, upper air parameters were more favourable for damaging winds on the 19th, on a larger scale as well. Could be similar to July 10th in coverage of severe storms though. Link to comment Share on other sites More sharing options...
Chicago Storm Posted September 10, 2013 Share Posted September 10, 2013 Topped out at 93 here and 96 at MDW today. ORD hit 95, which tied the record (1983). Link to comment Share on other sites More sharing options...
michsnowfreak Posted September 10, 2013 Share Posted September 10, 2013 70 last night was one of the cooler lows in the area as well, thanks for proving my point.

Brewers Posted September 11, 2013 Share Posted September 11, 2013 High of 96 at RAC and 95 at MKE. Only four other times there have been a 95+ degree high on or after Sept 10th in MKE (9/10/1931 - 97, 9/13/1939 - 96, 9/14/1939 - 98, and 9/15/1939 - 99) Link to comment Share on other sites More sharing options...
Stebo Posted September 11, 2013 Share Posted September 11, 2013 DTW was one of the "cool" spots today for sure. It doesnt change the fact that they USUALLY are one of the warm spots. They are also one of the furthest South in the area and close enough to get a marine influence to hold temps up on some nights. Partially one of the reasons why the visibility tends to be less than 10 miles here at night compared to other regions. I would bet Grosse Isle and Monroe have similar temperature profiles to KDTW most nights. Link to comment Share on other sites More sharing options...
Geos Posted September 11, 2013 Share Posted September 11, 2013 94° here today. Seeing quite a few trees dropping their leaves already. Dryness Tomorrow looks like light and variable winds. Probably see cooler readings near the lake as inland areas are near 90°. Link to comment Share on other sites More sharing options...
daddylonglegs Posted September 11, 2013 Author Share Posted September 11, 2013 The 'rain' that fell was enough to get my tshirt a little wet...it more or less evaporated as fast as it fell..for a whole 4 minutes or so...turd. Link to comment Share on other sites More sharing options...

I'm going to take a stab and say it's a double rounding error in that software from conversions. 96.8F is conveniently 36C on the nose. So if the actual temperature was 96F, that's 35.6C. A software program might just take that and round up to 36C. Then it gets converted back to F at 36, instead of 35.6 and voila ... you get an extra degree. I've noticed this bug on many a 3rd party weather software. Link to comment Share on other sites More sharing options...
Thundersnow12 Posted September 11, 2013 Share Posted September 11, 2013 Made it to 95 here. OT but giving another AMS talk this winter probably. Haven't picked an event yet but thinking 11/30-12/1/06 Link to comment Share on other sites More sharing options...

cyclone77 Posted September 11, 2013 Share Posted September 11, 2013 Made it to 95 here. OT but giving another AMS talk this winter probably. Haven't picked an event yet but thinking 11/30-12/1/06 Nice. One of my favorite storms for a variety of reasons. I did an animation on that one a few years back... MLI set a new record today of 97, which beat the old record of 95. They're now up to 36 consecutive days without measurable rain. Link to comment Share on other sites More sharing options...

Partially one of the reasons why the visibility tends to be less than 10 miles here at night compared to other regions. I would bet Grosse Isle and Monroe have similar temperature profiles to KDTW most nights. KDTW year to date is the same as KTTF. KTTF has much more marine influence and is further south. This UHI effect will be more pronounced after 3-4am. 2 Degrees warmer can be the difference between an anual ranking of 30th or 50th warmest year on record... or more.
