What do you think your average September high will be? (Chicago, days)

[Caleb Yeung]

Seeing as it's the 8th, and NO ONE made it, I thought I'd take the prize.

What do you think your average September high will be?

[Dean York]

Average is 22C so far, I reckon probably 18 or 19C. So about average really.

[dunno what to put here]

About average I reckon.

[cloudcrash619]

Above average

[MeteoMan]

14-15°C, below average.

It's already below 16 and will be 15 by a week's time, maybe a bit less so it's probably a dead cert.

GFS model projection puts Buxton at 15.4°C by the 14th.

[Mac15]

A little below average.

[Full Overcast]

Below average

[Ariete]

Average so far is 20C, so above average. According to preliminary GFS perhaps well above average.

[ksolina]

About average, perhaps slightly above average if the cooldown in the latter part of the month won't be as strong.

[chicagogeorge]

First seven days of September, average max is 28.2C at O'Hare and 28.6C at Midway airport in Chicago. The 30 year average high for first seven days of September is 26.3C


Euro and GFS suggest above average September
