Some intense thunderstorms over NE Spain at the moment, which is nothing unusual, but also some intense thunderstorms over the Black Sea at the moment - is this unusual?

and the answer is that thunderstorms are frequent on the north side of the Black Sea, but I wouldn't know about the intensity.

I have to imagine the Foehn effect must be playing a pretty big role for this to happen.

Been following the weather or rather the forecasts for several cities in that part of the world. Cuiaba, of Mato Grosso, Brazil, is an interesting one.

In Winter, it is generally very hot, dry and sunny with max temps pretty much consistent, usually between 33 - 36 C for days on end, with mostly light N to NW winds. Its resembles one would experience in Madrid or Cairo in July and August.

However, just once every now and then, a cold blast sweeps across the region from the S Polar Regions, causing temperatures to tumble dramatically, sometimes the max temps falling right down into the teens, often with dull conditions and brisk S to SE winds, and maybe sporadic rain or showers (other times bone dry). Never lasts very long, in roughly 1 to 3 days time, temperatures climb back dramatically back into low/mid or even high 30's, with prolonged drought and incessant sunshine lasting for say next 2 weeks to even for the rest of its winter.

The forecast for Cuiaba for next 5 days is very hot, dry and sunny with max of 39 - 40 C (source: BBC Weather). However, a max temperature of only 13 C was recorded there on 14 and 15 June 2023, with mostly cloudy conditions and occasional rain (source: www.timeanddate.com)

For those old enough to remember the original CSI series, they had episodes where it was pouring with rain in  Vegas

Very interesting read and never had this major storm hitting California for over 80 years. so exciting observation for me to see how much rain and very cool maxes reached over Death Valley in August.  I been recording Death Valley since early 2000 and highest rain was over 1 inch but never several inches in a day so that storm might deliver it.
