Hoosier Posted July 7, 2012 Author Share Posted July 7, 2012 22z RAP has the I-80 corridor including Chicago already above 100 at 10am tomorrow morning lol. NAM has been indicating something like that for the past several runs. Models may be a little optimistic but wouldn't be surprised to see some areas get to 100 by 11 AM or so (barring any convective debris). Link to comment Share on other sites More sharing options...
cyclone77 Posted July 7, 2012 Share Posted July 7, 2012 NAM has been indicating something like that for the past several runs. Models may be a little optimistic but wouldn't be surprised to see some areas get to 100 by 11 AM or so (barring any convective debris). Just now got around to looking at the 12z Euro. Looks a tick faster on the fropa than the 00z. Gonna be a close call for ORD if that works out. The very warm start will certainly help their prospects though.

daddylonglegs Posted July 7, 2012 Share Posted July 7, 2012 That is it for me boys...hopefully I pray this doesn't happen again for another 100+ years... Looks like I should be experiencing cooling by daybreak with lower temps and lower humidity. Let a super ridge built into the west for the rest of summer.

Thundersnow12 Posted July 7, 2012 Share Posted July 7, 2012 Geez MDW still sitting at 97. Temps have gone up the last few hours as the lake breeze retreated. Link to comment Share on other sites More sharing options...
Hoar_Frost Posted July 7, 2012 Share Posted July 7, 2012 Geez MDW still sitting at 97. Temps have gone up the last few hours as the lake breeze retreated. Yep. Even Northerly Island was back up in the mid 90's at the ob. It's going to be interesting to see just how warm it remains in the urban core (even including ORD and MDW). That will be a key to just how warm it can get tomorrow before the front passes. Link to comment Share on other sites More sharing options...
Chicago Storm Posted July 7, 2012 Share Posted July 7, 2012 Looks like the 0z NAM doesn't bring the front through until about 20z around here. 100+ opportunity for the Chicago and Detroit areas. Link to comment Share on other sites More sharing options...
Geos Posted July 7, 2012 Share Posted July 7, 2012 Skilling going with 94° tomorrow at ORD. Mentions post frontal thunderstorms - isolated. Currently 85° here at 9:30. Link to comment Share on other sites More sharing options...

Skilling disagrees -- interestingly. If the front remains at bay until even early afternoon (18z), 100 would still be possible at ORD since 100 has been reached there during the noon hour the last few days. It'll be an interesting scenario to watch. Link to comment Share on other sites More sharing options...
cyclone77 Posted July 7, 2012 Share Posted July 7, 2012 Looks like the 4km NAM brings the front through ORD between 1-2pm. Certainly late enough they should have 100+ in the bag by then barring no cloud issues. Link to comment Share on other sites More sharing options...

Wondering if he's thinking about cloud cover along the front holding down temperatures? Link to comment Share on other sites More sharing options...
hm8 Posted July 7, 2012 Share Posted July 7, 2012 If tomorrow hits 100 at ORD, it would be the first time with 4 consecutive 100 degree days, correct? Link to comment Share on other sites More sharing options...

Wondering if he's thinking about cloud cover along the front holding down temperatures? Could be I guess. IMO 94 seems a bit low though considering it could easily be that at 10am. I believe it was 93 at 10am there today. It's gonna be interesting to watch, but if the front hangs up at all they could even give today's temps a run for their money.

Hoosier Posted July 7, 2012 Author Share Posted July 7, 2012 AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL 1001 PM CDT FRI JUL 6 2012 DISCUSSION 958 PM CDT BUMPED UP MINIMUM TEMPERATURES A LITTLE ACROSS THE CWA...AND ESPECIALLY IN THE CHICAGO METRO AREA FOR TONIGHT. TEMPERATURES SO FAR THIS EVENING ARE STILL REGISTERING AS WARM AS IF NOT A FEW DEGREES WARMER IN PLACES AS COMPARED TO LAST NIGHT...AND SHOULD BE ABLE TO MAINTAIN A LIGHT SOUTHWEST GRADIENT TONIGHT...WHEREAS LAST NIGHT WINDS BECAME CALM FOR SOME AREAS. DID NOT MAKE ANY CHANGES TO FORECAST FOR SATURDAY...THOUGH THERE ARE CONCERNS TO NOTE...MAINLY REVOLVING AROUND FRONTAL TIMING. THE 18Z AND NOW 00Z NAM CONTINUE TO COME IN WITH A MID AFTERNOON FROPA...AND THINK THIS MAY BE A REASONABLE SOLUTION //IF NOT SLOWER// SINCE IT MAY BE DIFFICULT FOR THE COLD FRONT TO PUSH INTO THE EXTREME HEAT WITHOUT MUCH CONVECTION/COLD POOLING TO ASSIST. THE 00Z NAM DOES EVENTUALLY DEVELOP ISOLD/SCATTERED CONVECTION ALONG THE FRONT SATURDAY AFTERNOON ACROSS FAR NORTHERN ILLINOIS. GIVEN THE MODERATE TO STRONG INSTABILITY THAT IS EXPECTED...WEAKLY CAPPED DURING THE PEAK HEATING OF THE AFTERNOON...EVEN MODEST FORCING ALONG THE FRONT SHOULD BE SUFFICIENT TO KICK OFF SOME THUNDERSTORM ACTIVITY. STRENGTH AND POSITION OF THE LOW LEVEL CONVERGENCE ALONG THE FRONT IS THE BIG QUESTION MARK...BUT MAY BE BETTER OVER NORTHEASTERN ILLINOIS WHERE THE FRONT WILL LIKELY SURGE AHEAD DOWN THE LAKE. IF WE DO GET A LATER FRONTAL PASSAGE...THAN 100F AT ORD IS NOT OUT OF THE QUESTION...LEADING TO RECORD BREAKING FOURTH CONSECUTIVE 100 DEGREE DAY FOR CHICAGO.

Hoosier Posted July 7, 2012 Author Share Posted July 7, 2012 There is a large discrepancy (like 10 degrees) between MET and the NAM 2m temps for ORD. MET has 93 while the 2m temps are safely into the 100s. As long as the frontal passage occurs after noon then I'd say it's likely they get to 100.

Thundersnow12 Posted July 7, 2012 Share Posted July 7, 2012 0z NAM at 18z tomorrow. This will be fun to watch but I think there is a pretty solid shot at ORD tagging 100 before the front gets there. Link to comment Share on other sites More sharing options...

snowlord81 Posted July 7, 2012 Share Posted July 7, 2012 Still 88 at IND. My temp has actually gone up in the last hour! 81.7 out in the boonies. Has IND ever had a low above 80? Link to comment Share on other sites More sharing options...
Hoosier Posted July 7, 2012 Author Share Posted July 7, 2012 My temp has actually gone up in the last hour! 81.7 out in the boonies. Has IND ever had a low above 80? Yes, multiple times when the observation site was in or closer to downtown. Hasn't happened at the airport. Link to comment Share on other sites More sharing options...
snowlord81 Posted July 7, 2012 Share Posted July 7, 2012 Yes, multiple times when the observation site was in or closer to downtown. Hasn't happened at the airport. Wow, I guess thats a record to shoot for then. I think they may do it. They are 5 degrees higher than last night still and with the dewpoints pretty high it may stall the temps long enough. If the dews are this high tomorrow with the temps between 102-106 the HI may really be cranking. Im going to try to tough it out and go to the speedway tomorrow for some sportscar testing.

Hoosier Posted July 7, 2012 Author Share Posted July 7, 2012 Dews are several degrees higher at IND than last night. Coming off a high of 105 with good low level moisture in place...if there's ever a night where 80 could happen you'd think this may be it. Link to comment Share on other sites More sharing options...

snowlord81 Posted July 7, 2012 Share Posted July 7, 2012 You read my mind Hoosier. I was really hoping to atleast tie the all time record during this heatwave. I dont think it will happen tomorrow, but I dont think were done for the summer yet. Im thinking IND will hit 103-105 again. We will see. Link to comment Share on other sites More sharing options...

Winds have gone calm so they could easily start losing 2-3 degrees an hour at least for a couple hours. I think it'll be close. Link to comment Share on other sites More sharing options...
