Diabolical weather in Portugal

[Fr J Hackett]

Posted a YouTube discussion on jet streams becoming curved instead of straight which sends down this kind of confused weather we are experiencing but it was deemed not acceptable to post

Jet streams have always fluctuated either allowing lows to track further south or highs to move North.

Yes but inthe discussion the jet streams apparently are becoming more contorted ,hence thes days of fine weather then a sudden change to cold.
