Morning all. Finally felt well enough to clamber out of bed and log in to look at the models again.




Thanks again to everyone for their well wishes. It was quite a shock to feel so ill and collapse like I did, but our wonderful NHS have me well on the road to recovery. 😀

If we don't get a wetter than average Autumn and winter though, I fear next year will see is in a rather severe drought.

It would be interesting to see how the first day in the autumn when temperatures dip below 0C has changed in the last 50 years for selected locations across the UK. Not sure if it's easily available?

Interesting thought which prompted me to inspect the MIDAS temperature records. In some ways using a baseline of 50 years would skew the results as the 70s and 80s were not typical in terms of climate. To see the broader picture I extracted dates of last frost of spring and the first of autumn from the longest records dating from at least 1880 (5 in total spread across the UK.) The results are quite interesting and not immediately what we might expect.


As usual I've struggled with posting an image so the graphs are viewable on the link below.


The top graph shows the 30-year average last date of frost at Stornoway, Durham, Oxford, Armagh and Braemar (the value for each year is the 30-year average ending on that year so the value for 1910 spans 1880-1910.)


The bottom graph is the same format but shows the 30-year average first frost of autumn.


The dates are calculated as Julian Day so 1st April is 91, 1st May 121 etc (disregarding leap years)


The most dramatic changes seem to be at Stornoway where the average date of the first frost is now at the end of November, compared to end of October/early November 50 years ago.

Morning all. Finally felt well enough to clamber out of bed and log in to look at the models again.
Looks like there's continued dry weather coming up - what an exceptional summer we've been having.
It's a shame for me that I had to cancel my holiday due to my illness, but thankfully I'm now on the mend and hopefully I can go away at the end of next month to make up for it.
TBH, I won't mind what the weather is at the end of September, but this pattern seems pretty stuck, so I wouldn't be at all surprised if we continued rather dry.
If we don't get a wetter than average Autumn and winter though, I fear next year will see is in a rather severe drought.
Thanks again to everyone for their well wishes. It was quite a shock to feel so ill and collapse like I did, but our wonderful NHS have me well on the road to recovery. 😀

Models: summer continues unabated in the South and East at least. The fourth summer month, September, perhaps even ushering in a UK high. Some rain, somewhere, tomorrow. Probably end up on the east coast of Canvey Island!

Today's silly chart must be the P8 at the end of the GFS 6z run.


Builds up gradually through the high 20s to low 30s with a Cheltenham 37 that would bust the September record from 1906.

GFS 12Z Op is showing little rain into tomorrow for the extreme east of Kent and Essex but much larger amounts slightly further west in parts of Essex, Herts, Cambs, Norfolk, Suffolk and London.

GFS12z looks very dry and warm long term (on TWO, Wetterzentrale yet again being very slow this evening).

Assume it’s a bit of an outlier.

A bit of a N/SE split on the models this evening with 0mm of rain here over the next 7 days and an inch of rain modelled over Chingford in the next 24 hrs. 


Seriously though a rather warm and settled outlook for many areas after that band of intense rain in parts of the SE in the coming hours. On that note the UKMO high resolution model has up to 40mm over the capital. It will be interesting to see what materialises when the time comes, not that it will do much to alleviate the dry conditions due to the intense but brief nature of the precipitation.

The UK's zombie summer rises again After yesterday's WX chart showing cool air penetrating much of W Europe, this morning not only keeps week 1 generally warm but in week 2 holds cold air from the NE at the Polish border while warmth moves up from the S over France  and Britain. Rain well distributed in week 1; in week 2 a dry area appears from Iceland - Denmark - Poland and damp elsewhere (also significantly  different from yesterday's chart)


Jet - little action until Sat 3rd when some streaks over N Norway and the suspicion of a loop W of Britain; both fade and a new loop starts to develop over Britain Thu 8th


GFS - after today, a general rise of pressure mostly to the N but splitting to E & W Wed 31st as a trough of LP establishes over Britain resolving into a localised depression Ireland 1010mb Fri 2nd which retires W-wards for a while (with some warmth from the S) but returns across Britain to 1000mb N Sea Sat 10th.


GEFS - mean temp near or a little above norm but with a big spread around Sat 3rd; rain now in the S and after 3rd generally, esp at that stage in the N


ECM - similar to GFS.
