Cold Edmonton is down to 9.0c which is nearly 3c below normal...almost had an ice day yesterday with a maximum temp of 0.2c.

[Katrine Basso]

I think South Ockendon will go down to 17 °C maximum and 7 °C  minimum.

Does anyone know what the highest overnight minimum for september is? 

I see Helene is bringing some high ivernight temperatures this week and in my location it may not drop below 18oC monday night so was wondering if it's even close to a record?

Thank you! Do you have a source for that information? I can never seem to find overnight low stats. It seems they are very rarely reported

I would think that this is our low point for this month, up into the mid 15c's likely next week, night time temps looking balmy for a few days.

[The PIT]

Sunny Sheffield down to 14.2 -1.0C below normal. Rainfall 13.5mm 20.6% of the monthly average

[NorthYorksWeather]

14.3c here to the 14th, bang on the 1981-2010 average.

Looking like going up quite a bit this coming week.

[The PIT]

Sunny Sheffield still at 14.2C -0.9C below average. Corrected Rainfall is at 13.5mm 20.6% of the monthly rainfall.

[Summer Sun]

An interesting 2nd half of the month coming up, warming up for a few days then a colder snap followed by milder weather again at the very end of the month, a higher CET for the 2nd half looking very likely now unless we get the colder air dig in thats been showing up on some runs.

Over the years the GFS has provided us with some great entertainment.

[ItNeverSnowsInWindsor]

It certainly looks interesting for the second half of September with increasingly cool unsettled weather being shown by GFS.

Cloudy/Miserable Edmonton is down to 7.5c which is 4.3c below normal..weather stays well below normal for the rest of the week.

[NorthYorksWeather]

Not much change here 14.3c to the 16th, 0.1c above the 1981-2010 average. 14.2mm of rainfall

Some rises look likely over the next few days.

Thats incredible only up by 0.1c, was expecting at least a 0.2c rise after yesterdays warmth.

[BornFromTheVoid]

The 06z gives us quite a cool spell next week, with the 4 days up to and including the 27th averaging just shy of 10C. The last time we had a 4 day spell averaging under 10C in September... 2012. And before that, we have to go back to 1993! I'm sure it will be gone by the 12z though!

I'll hopefully have time for a full update a little later on.

[The PIT]

Sunny Sheffield up to 14.5C -0.4C below normal. Rainfall 15.7mm 24% of average.

[Roger J Smith]

Not sure if BFTV will provide a more detailed forecast but looking at 12z GFS, I would say a downward drift to 14.4 by Tuesday 25th followed by a slight rebound with some 16-17 values, last day of month cooler again, so most likely finishing point in the 14.2 to 14.8 range, before corrections, and 14.0 to 14.7 after corrections.
