September 2017 C.E.T. forecasts

[damianslaw]

Touch and go whether we end up below or above the 61-90 average or bang on. Expect a climb over the next 3 days, but with likely downward corrections, I would say a 50% chance below, 50% chance above, and a 70% chance bang on average.

 

[The PIT]

Sunny Sheffield still at 12.8C -1.3C below normal. Expect finishing point for us will be around 13.2C to 13.4C

[NorthYorksWeather]

13.4c here to the 26th, 0.3c below the 1981-2010 average.

A rise likely tomorrow to 13.5c but a ? on whether we can remain at or below average by end of month.

[Summer Sun]

13.7 to the 27th

Bang on the 61 to 90 average

0.5 below the 81 to 10 average

___________________________________________

Current high this month 15.1 to the 5th

[The PIT]

Sunny Sheffield up to 13C -1.1C below normal. One more warm day and then a cool Saturday so looking at 13.1C possibly the ending point.

[damianslaw]

A probable increase to 13.8 degrees tomorrow, then perhaps no climb on Saturday, and with adjustments we might just go under the 61-90 average.

 

[Summer Sun]

13.8 to the 28th

0.1 above the 61 to 90 average

0.3 below the 81 to 10 average

___________________________________________

Current high this month 15.1 to the 5th

[NorthYorksWeather]

13.5c here to the 28th, 0.1c below the 1981-2010 average.

Potential drop tomorrow depending on tonights low so either 13.4c or 13.5c likely to be landing zone.

I will go first and punt for something reasonably close to the average of the last 15 years. I think we will likely continue on an unsettled note but with a lack of any low minimums. 

13.9c for me please. 

Come to papa

[The PIT]

No change in Sunny Sheffield still on 13C -0.9C below normal. A rise to 13.1C  for tomorrow. If Saturday ends the way forecast back down to 13C and -0.8C below normal.

3hrs late 13.7c

That 3hrs of extra time might just have helped this month . To be fair was posted in New York so technically within the time ?

Final statistics for Crosby are as follows:

 

Lowest min: 6.8°C

highest min: 15.0°C

mean min: 11.4°C (+0.4)

lowest max: 14.5°C

I won’t be posting  statistics again until the end of this month as I don’t have a rolling average so there’s no point.

All I see on the Hadley CET website is figures horizontally across all the pages and cannot make out what column they should belong to.  How do you know 13.5 is the official September CET? I have not been able to make that out or read it properly in the mess the pages are in, even it has already been published.

It is 13.5

[Dancerwithwings]

The Hadley website states 13.8c provisionally to the 29th... as N-E- Blast asked, how did you come to that figure of 13.5c.

Well it's ranked as 13.5, the finalised figure is 13.53 and it's in the 1659 to 2017 list as 13.5

[Dancerwithwings]

Do you have a direct link, I'm looking for that 1659 to 2017 list you mentioned ?

[North-Easterly Blast]

So despite the CET for September 2017 being quite close to average, it was actually one of the cooler Septembers in recent years; it was the same as the CET for September 2008, and in the last 23 years, only the Septembers of 2012 and 2015 were substantially cooler.  

Nice to see that September 2017 at least bucked the trend of the last 20 years a bit, even if it wasn't that much cooler than average.

Yes, I'm pleased with the September CET and it certainly didn't feel like an extension of summer this year, despite the warmer final few days of the month.

The last time both August and September were below their 1961-90 averages was in 1993 by the looks of it.
