September 2017 C.E.T. forecasts

[Mark Bayley]

15.1c please 

[damianslaw]

A slightly above average - I will guess 14.4 degrees, another NW-SE marked divide again, could be some chilly nights at times though, indeed the first couple of nights will be decidedly chilly. Suspect it will be very similiar to August weatherwise. 

[Stargazer]

14.5 please

[seaside 60]

Have no idea or inkling on this month after August.

Lets plump for above average but not by to much.

14,9 c for me please.

[Don]

I think September could be a variable month.  I will go for 14.6C please.

A very average 14.2C please.

[weirpig]

12.1 cold 

[AtlanticFlamethrower]

15.3C

[Singularity]

Such variety in the model output but I can just about pick out a predominant warm signal for maybe half the month. An uncertain 15.2*C is my guesstimate.

[Duncan McAlister]

15° for me please.

[davehsug]

14.3C please. No major signals for anything in particular, probably means a month around or just a little above average.

56 so far, median is 14.5 C. 

full table of entries to be added to thread on Tuesday 5th (don't worry I won't forget, but planning to be away on our forthcoming long weekend, it is sunny and hot here). August running +2 to +3 C around these parts (anomalies). NYC and DCA and ORD actually below normal, not too often do we see this nowadays. Harvey pushed IAH below their normal too (not to mention 11x normal August rainfall). 

[Gael_Force]

14.7c please.

[stewfox]

3hrs late 13.7c

[ItNeverSnowsInWindsor]

[Summer Sun]

13.4 to the 1st

1.5 below the 61 to 90 average

2.0 below the 81 to 10 average

 

[BornFromTheVoid]

With a min of 7.9C and maxima likely to be around 19C, we should see an increase to about 13.7C on tomorrows update.

After that, the 06z GFS has the CET at:

13.9C to the 3rd  (14.4: -0.9)
14.8C to the 4th  (17.3: +2.6)
15.0C to the 5th  (16.0: +0.8)
14.9C to the 6th  (14.4: -0.7)
14.9C to the 7th  (14.5: -0.5)
15.1C to the 8th  (16.4: +1.4)
15.1C to the 9th  (15.4: +0.7)
15.1C to the 10th  (15.1: +0.4)
15.0C to the 11th  (13.7: -1.1)

After a cool opening 2 days, the rolling CET remains close to average from the 5th onward. Few guesses can be ruled out at this early stage.

[NorthYorksWeather]

13.4c here to the 1st, 1.5c below the 1981-2010 average.

Looking at 5 day forecast a rise towards and above average is likely.

[Summer Sun]

13.6 to the 2nd

1.3 below the 61 to 90 average

1.8 below the 81 to 10 average
