After today Chi/ORD's average high will likely be 76.4F/24.7C and MDW's will likely be 77.3F/25.2C. Keep in mind that we just had one of the coolest April's on record with an average high of only around 10C

To be fair the predicted temperatures went down as time went by...

Then weather online's 7-day forecast means nothing when they are 10 degrees off. I would've probably guessed it more accurately.

I really doubt that their forecast went down from 28C to 18C or close to that. I have noticed that with weather online.

If the forecast was mostly sunny during an earlier forecast but changed to showers due to a disturbance the forecasters only saw come recently the predicted high can change drastically.

Weatheronline just uses GFS data, and as such will reflect whatever GFS is showing. Model output 7 days out is rarely very accurate.

The forecasts are from raw data & are updated with every model update. It is a forecast, nothing beyond 2 or 3 days is accurate from any source...
