  1. It’s gonna be hard for any development to occur until post frontal passage, due to the strong capping...as evident by ~16C at 700mb. .
  2. The MCS along the IA/MN, if it maintains, will be the story for today...and a likely derecho, which would take aim for S WI/N IL. It developed 9-10PM last night near the MT/WY/SD border area. It has had widespread reports, some of which have been sig. .
  3. MLI is already up to 91 as of 10AM. .
  4. Late response, but it ended up making it to about where I thought it would...Through the metro due to the lake enhancement, but not much farther than that. Luckily it moved through very early, and was able to wash our fairly quickly earlier this morning. Cirrus debris from the overnight MCS has cleared the area as well. However, cirrus from the MN/IA/WI could possibly become an issue in a few hours. .
  5. It’s still 86 at ORD and MDW as of midnight. .
  6. 0z DVN and ILX soundings show that there are 2 to 3 different inversions at different heights. The lowest inversion is around 900mb, which goes to show why temps didn't exceed the mid 90's anywhere.
  7. Indeed hit 93 at ORD. Topped out at 94 here. .
  8. High and dry. Nothing getting here with 14-16C at 700mb. Mega cap and ridging. .
  9. S and SW winds that day, so that would be my guess. .
  10. That La Crosse combo is bigly. They’re taking advantage of the valley for DP’s and down-sloping for temps. .
  11. 94/82/117 at K06C a bit ago. Fairly rare territory for these parts. .
  12. 93/81/115 at K06C. Highest combo in the area it appears.
  13. Keeps going... 92/81/114 here. 06C is at 92/81/112.
  14. Make that 91/80/110 here. 91/80/109 K06C (Schaumburg Airport)
  15. To say i'm surprised is an understatement. It will likely hold, breaking the high min temp for the date of 78 (2011).
  16. Cirrus debris from the morning MCS in WI has been hanging on this morning, and only slowly clearing. Additionally, a remnant disturbance in S WI is pushing ESE, with an OFB and a canopy of lower level clouds. At this point, it looks just when the cirrus will clear, the stuff from WI will move in. Odds are today will under-perform once again. .
  17. ORD is still at 81 as of 5AM. Still have another hour to drop below 80, and there’s and OFB moving in from the weakening WI MCS...So a few things working against an 80+ low, but it’ll be close. .
  18. I wouldn't discount, given LOT and IGQ are at 79. Well, might discount the 82 a bit at JOT...but 80 is reasonable.
  19. I'm thinking 100 is out of the question for anyone at this point, unless along/west of I-35. Short term guidance, which has been on the hotter side, seems to be over-mixing a bit. Also add in a good chunk of IA/MO/IL has seen at least one MCS producing 1"+ rainfall totals the past few days.
  20. Forgot to revise today, but still would have been wrong thinking 90+ post MCS. Gonna revise to 95 for Fri/Sat.
