kab2791 Posted July 5, 2012 Share Posted July 5, 2012 We are going to struggle with high temps today due to convective debris from early morning mcs and developing convective cells already. The forecast of 98 may bust if we cannot clear out enough. Link to comment Share on other sites More sharing options...
Hoar_Frost Posted July 5, 2012 Share Posted July 5, 2012 It's interesting to note that ORD is running a degree cooler compared to yesterday at the 0851 and 0951 observations. DPA, on the other hand, is a degree ahead. Link to comment Share on other sites More sharing options...
wisconsinwx Posted July 5, 2012 Share Posted July 5, 2012 Feel sorry today for the golf caddies at the US Woman's Open Golf Championship up in Kohler, WI. At least the weekend is shaping up to be much nicer. Sure hope I'm still alive in 2020 as me and the wife will do anything to be at the Ryder Cup Matches at Whistling Straights. Hole Marshall would be sweet. Should be out there volunteering for the Woman's Open as then you're given the opportunity to volunteer for the 2015 PGA Championship & 2020 Ryder Cup. Good thinking! I would like to do the same. As it is, I'm heading down to the John Deere Classic next Thurs/Fri to hopefully watch some of that tournament. Hoping for some cooler weather.

Chicago Storm Posted July 5, 2012 Share Posted July 5, 2012 ORD up to 91 as of the 10AM OBS...1F behind yesterday at this time. 22nd 90+ day of the year. Link to comment Share on other sites More sharing options...
kab2791 Posted July 5, 2012 Share Posted July 5, 2012 GRR ramps up high temps calling for low 100s today and mid 100s tomorrow. Jackson's point and click showing 107 tomorrow. Link to comment Share on other sites More sharing options...
turtlehurricane Posted July 5, 2012 Share Posted July 5, 2012 It's 1 degree cooler than this time yesterday at MSN, 91 °F. Kinda lame this isn't even the last day of the extreme heat. Link to comment Share on other sites More sharing options...

turtlehurricane Posted July 5, 2012 Share Posted July 5, 2012 Some patchy altocumulus are present here now ... Yeah, solar flux is running 200-400 w/m^2 lower than yesterday. Kinda surprising we're pretty much as hot as yesterday with much less flux. Hard to tell if this will continue looking at visible satellite, the clouds causing this are almost invisible to it.

WxMidwest Posted July 5, 2012 Share Posted July 5, 2012 I think the dewpoint starting out lower at the same time a day in many locations then yesterday could be a positive attribute to soaring highs for today. Rockford is only 2 degrees off, Yesterday... Link to comment Share on other sites More sharing options...
A-L-E-K Posted July 5, 2012 Share Posted July 5, 2012 ORD shot up to 96 Link to comment Share on other sites More sharing options...
WxMidwest Posted July 5, 2012 Share Posted July 5, 2012 Also, the convective feature over West Iowa/MN looks to have warming tops, and should be collapsing looking at the Infared. There may be a few debris clouds coming in from it, but should quickly be wained off by the heating of the day. Link to comment Share on other sites More sharing options...
beavis1729 Posted July 5, 2012 Share Posted July 5, 2012 ORD shot up to 96 That's 1F above yesterday at this time...and Td is 4F lower. If ORD has a normal diurnal heating curve today (unlike yesterday when the max temp occurred around 1:30 PM), they should be able to surpass yesterday's high of 102. This assumes no significant cloud cover to impede heating. Link to comment Share on other sites More sharing options...
Brewers Posted July 5, 2012 Share Posted July 5, 2012 98 now, 2 degrees warmer than yesterday at this time. Maybe we can make a run for the all time record. Link to comment Share on other sites More sharing options...

There may be a few debris clouds coming in from it, but should quickly be wained off by the heating of the day. It's funny that you should mention that. I'm pretty damn sure that the altocumulus that I referenced about 20 minutes ago simply evaporated. That said, it seems a bit hazier than yesterday even if dewpoints are a few degrees lower. I suspect that the haze is more attributable to other pollutants (besides water). At 97 here, which is probably a couple of degrees ahead of 24 hours ago. Had 101 yesterday.

Hard to tell if this will continue looking at visible satellite, the clouds causing this are almost invisible to it. Thicker wildfire smoke. The plume was visible over NE/SD/ND/MN last night.

WxMidwest Posted July 5, 2012 Share Posted July 5, 2012 Yeah, It's definately still on today, temp has rose to 97-98 at some of the local stations here. It looks we are not but 20-30 minutes behind yesterday and that time differential gap is quickly being made up. I'm starting to wonder about Saturday, just reading some of the other posts on here, if the Frontal passage is too slow, it could give us a chance of 4 days in a row of 100+...

LizardMafia Posted July 5, 2012 Share Posted July 5, 2012 IND has been +3 with the temps each hour this morning, when compared to yesterday. So maybe a run at the all time high today (106) is possible.. Link to comment Share on other sites More sharing options...
wxman_ind Posted July 5, 2012 Share Posted July 5, 2012 Per IND's latest tweet/FB posting: 99 degrees at IND. Record Tied. Link to comment Share on other sites More sharing options...

I'm starting to wonder about Saturday, just reading some of the other posts on here, if the Frontal passage is too slow, it could give us a chance of 4 days in a row of 100+... Assuming a frontal position even just to the north of the Ill-Wisc border (which is reasonable at this point) and based on the degree of pooling of dewpoints along fronts lately (upper 70's), I could envision a scenario where temperatures didn't settle much below the lower or middle 80's in northern Illinois and far southern Wisconsin on Friday night. (Keep in mind that DeKalb CO-OP, for instance, had a low of 74 last night as did DPA, I believe.) Even if "classic" conditions for 100+ temperatures were not in place on Saturday, temperatures would have a running start toward the century mark that day. That will be an interesting situation to watch, and the idea of a hot Saturday in much of northern Illinois (and, of course, south- and eastward) is not one to be discarded just yet.

Hoosier Posted July 5, 2012 Author Share Posted July 5, 2012 12z MET has 109 here on Saturday. That is the warmest output I've ever seen for LAF. I don't really buy it though given 850 mb temps peaking around 26-27C. Should end up at least a few degrees cooler. Link to comment Share on other sites More sharing options...
Chicago Storm Posted July 5, 2012 Share Posted July 5, 2012 ORD is up to 99...1F ahead of yesterday. UGN/PWK up to 100. ENW leads the pack at 101. Link to comment Share on other sites More sharing options...
Hoosier Posted July 5, 2012 Author Share Posted July 5, 2012 FWIW, warmest temp ever recorded at ORD (this is not the same thing as warmest temp in Chicago) is 104, but the period of record only goes back to 1958. Link to comment Share on other sites More sharing options...

Hoar_Frost Posted July 5, 2012 Share Posted July 5, 2012 Just watched Skilling's 11:50 segment. He showed the RPM model output for temperatures today through Saturday. Interestingly, the warmest temperatures for much of northern Illinois outside of lake influence were on Saturday. Link to comment Share on other sites More sharing options...
kab2791 Posted July 5, 2012 Share Posted July 5, 2012 DET: 76 right now, down 19 degrees from yesterday at this time. To even have a shot at 90+ we need no more cells to develop and for the remaining clouds to push out. NAM actually shows lower 100s for SAT due to slower frontal passage.

Makes sense with the slower front on new runs. 850 mb temps are a touch warmer than Friday on the progs. Link to comment Share on other sites More sharing options...
