Spain likely to break April maximum temp records this week with over 38C a possibility 
https://www.theguardian.com/environment/2023/apr/21/weather-tracker-heat-spain-could-smash-april-temperature-record 

This follows on from March’s high temps
https://www.theguardian.com/environment/2023/mar/27/weather-tracker-spain-edges-towards-record-march-heat 

A bit worrying as we could well be exposed to this extreme weather pattern (plumes of subtropical air) in the summer as per last year.

BBC video suggests that 40C could be reached:

I have read today, that globally, this April is running colder than March.
Looking at the Arctic Ice extent record, presently the ice melt rate is much the same as it was in March which is usually higher.
North Atlantic synoptics have since last November been similar to those observed in the 1960's and 70's (IMO).
Is there any connection?

I think maybe just the Arctic region is running colder. Asia, South America and Northern and South Africa have all been experiencing significant heatwaves this month.

Indeed 850s 10c to 15c above average this week in southern Spain. Spanish April record will likely be smashed. 37.4c to beat.

What's driving the exceptional heat in Spain is the bone dry ground, which is how we got to 40+ last summer.  With ground moisture conditions in the UK much improved at the moment, I would view something similar as quite unlikely here.

According to the BBC Weather the maximum temperature forecast for New Delhi on 1st May is only 24 C, with thundery showers, some 14 degrees below normal. It would be an equivalent of a maximum of 3 C in London! 🙄

Some welcome respite from the horrendous heat they experience this time of year. That is exceptionally cool for early May and it is only making a slow recovery. Looking like still below average by the end of next week at a cool 39C.

It looks likely to me, looking at the North Atlantic pressure distribution both foretasted and over recent months, that we could well see much more thundery weather than we've seen for several decades.
Any views on this?

A sub tropical storm formed according to the NHC back in January however it won't be named. This is the earliest official tropical Atlantic system.

Much of Western Canada is experiencing a late spring heatwave. In particular southern British Columbia is going to see temperatures in the low 30s for all of this week, with a forecast peak of 35C on Friday - https://weather.gc.ca/city/pages/bc-45_metric_e.html  . 

Even northern BC will get into the low 30s and rapid snowmelt is forecast in the mountains.

These conditions will extend northwards into North West Territories where Fort Simpson could reach 30C on Thursday - https://weather.gc.ca/city/pages/nt-4_metric_e.html  .

Ah, Kamloops - went there 5 years ago and stayed at a Holiday Inn Express opposite a casino... popped over there and everyone was on strike, picketing outside the casino. Great fun!

It's one of those places where things can switch from winter to high summer (and back again!) in a matter of days.

Rainfall in Italy has taken the north of that country from extreme drought to serious floods with 8 people drowned.

https://earthobservatory.nasa.gov/images/151324/a-deluge-in-italy 

The link (with aerial photos) states 8" of rain in 24 hours in some areas, and the river Lamone rising from 1m depth to 11m in that time. However, there may still be droughts again this summer, as the depth of the snowpack in the Alps is much less than usual. 

Even a large river like the Po rose 5m - but it had been 3.3m below normal as recently as the end of March.

The charts don't offer much relief from heavy rain for the next two weeks

The Canadian wildfire smoke trail seems to have initiated its own circulation over the Dakotas. 

Update: remarkable "smoke cyclone"/ "smokestorm" has now moved south into central U.S., crossing the Canadian border near the MT/SD border. This low pressure system has entrained a massive amount of smoke from numerous large boreal forest fires in central Canada.#MTwx #SDwx #COwx
