Chicago Storm

I’ll go over. .

GFS finally caved and now shows the heat wave. The main difference now is that it has much higher DP’s than the Euro, thus less mixing/cooler temps. In this setup that is more of an unrealistic solution. .

who even compared it to 1953. .

Let’s try this again. .

.

Feedback will definitely help in this case. A more iffy day such as Friday could easily be 90° now, given the feedback and ORD warm bias.

Where did you find that info? .

Euro, EPS and GEM are all still onboard for a heat wave from Fri through late next week. Euro/GEM both still have a few days near 100° as well.

Quite a difference on guidance for the next week. Euro and EPS have a heat wave, Fri-Wed with near 100° temps on Mon/Tue. On the flip side, the GFS and GEFS are much cooler. GEM is more in between. .

Euro weeklies are a very torchy for Sept. .

you’re just as bad. .

40 90°+ days incoming for ORD. .

You lucked out or missed out, depending on your line of thinking. .

warning points are still a thing? .

Lies.

Halfway through August, if the month ended yesterday this summer would finish 3rd warmest on record for Chicago as 76.2°. Top 5 warmest summers on record... 1. 76.4° - 1955 2. 76.3° - 1995 3. 76.1° - 2012 4. 75.9° -1921 5. 75.5° - 1959 5. 75.5° - 1949 The highest temp at ORD has “only” been 96, so there hasn’t been big heat. Consistently warm has done the job though. .

91 ORD today (25). 89’d here and at MDW. .

90 at ORD (24) and here (22) today. .

But we want it nowwwww. .

This map is actually a good illustration of how the derecho quickly changed character rapidly as it pushed into the LOT CWA. It went from vortex dominant across DSM/DVN CWA’s, to MV dominant fairly quickly into the LOT CWA. My best guess on why this happened is...For one, the derecho had entered a post-mature stage...Second, the main vortex that moved from north of DSM-Marshalltown-CID eventually weakened as it encountered a disturbed environment from the RFD supercell. At this time it became more MV dominated. .

Hawkeye and surrounding folks of Cedar Rapids better have some damn good pictures/video to share when they get power back in another week or two. The more I hear about how things went there and see pictures/video from there, the more I want. .

This might be the dumbest post in this threat in a while. .

.

MV’s were not as predominant until the character of the derecho changed as it existed the DVN CWA, so I’m not sure there would have been many. .
