Fallen here to 7,5C here in central ish London with cold light rain this is really quite dire. Heating on.

It might not be relevant or applicable to other stations the Heathrow sun recorder was changed in late 2005. From Campbell Stokes recorder to automatic Kipp & Zonen sensor, it’s believed to marginally record less sun.

Today looks coolest day in CET area not in north of it though, chilly night and daytime temps looking more suppressed than expected. E.g. Rothamsted 0.7C low… 10.1C high… 5.4

On course to be dullest April in 26 years (1998) in London. The east has definitely faired much worse than west. Miserable, nondescript month really.

These people should be ignored.

Horror show pattern into early May on tonight’s GFS 18z…. takes one back to 2007-2012. The N Atlantic/Greenland blocking is difficult to shake off in spring with polar vortex out the picture.

They are much more notable later in month that’s the point. Using the point of 2018 an exceptional spring certainly demonstrates something. If we see a daily record with over half a century of data, it’s noteworthy at the very least.

Just done for Heathrow, preliminary high of 9C it’s tied lowest max on record for date with 1973. This is exceptional.

It’s April 22nd…. The facts are your wrong.

If you’re talking to me at least @ me thanks. In what way I have done that? All I’m saying temperatures are indicated to be well below average for late April, no one has mention snow and freezing temperatures and what can be expected at this time of year. You said about me being antagonistic, I think you should look at yourself, all you do is purposely try to undermine messaging, if anything cool is mentioned, it’s a repeated pattern from you. It’s as if it upsets you personally, I find it very odd it is just the weather.

Even this weekend has downgraded, it looks rather cold for most as NE’ly is introduced. Warm in west of Ireland closest to ridge.

Still seeing drips of SSW which occurred earlier in March this could be what’s responsible, it was a significant event so of course has potential for extended influence. I don’t believe it’s result of MJO that’s been in COD. Perhaps weakening El Niño also a factor nothing we could get on side during winter remained strong.

“Slightly below normal” involves 5C even 6C below average T850s. A long time since I’ve seen such a deviation below.

Well the data suggest otherwise also signalled below on 1961-1990, below is Birmingham next week looks even cooler than this week, you must also consider the average for further in April is warmer, so using overall mean is not wise.
