Some serious heat building into southwestern USA. Just look at these 500hpa geopot heights forecast for the coming days approaching 600dam from northern Mexico into southwestern USA. That's mid-summer heatwave territory!!! The 850hpa temperatures show potential low 40 to mid 40 celcius (at...

Strange happenings with the polar vortex. Months of stretching out, then finally we get the collapse and split 14-10 days ago, now the PV has re-organised somewhat and become one. Latest 10hpa models forecast another split in the 10 to 15 day range. Can't recall ever seeing such strange...

While many are enjoying the spring-like weather across much of Europe, how much longer will this pleasant weather last? There are strong signals for the Madden–Julian Oscillation (MJO) shifting eastward faster than expected towards the Atlantic by mid-month which could result in increasing...

High cumulative precipitation heights in the Mediterranean and Portugal in early 2026 Based on NASA's GPM IMERG-Early satellite rainfall data, as analyzed by the climatebook scientific team, the spatial distribution of cumulative precipitation in the wider Mediterranean region is presented on...

Looks at the spike in warming at the 10hpa level 😱

The 7 days temperature anomaly for the first week of February. Shows nicely where the block over northern Europe has dropped arctic cold over northern & eastern Europe over the last couple of weeks. Interesting to see a small slice of low anomalies creeping into far northern Netherlands. This...

You see why the cold has been displaced south. Notice how warm the arctic currently is in the anomaly 2m temp chart.

Interesting article on the collapse of the polar vortex and the impacts in the mid latitudes. There is already a warming trend in the high arctic as the cold transits south...

Very impressive cover across much of the northern hemisphere. Russia is completely covered, Canada looks good, and most of Europe is looking healthy for the first time in many years. Seems to be a void across the States, of course plenty of winter remains. Here in the Netherlands we had a...

Can I pick some clever brains in here? I know very little about climatology, but I do find it very fascinating. I hope to learn from you folks. One thing I am very curious about is your thoughts on when any true winter weather can be expected for the Netherlands, Belgium and the low countries...
