Following what appears to have been MAINLAND Spain’s warmest March day in history Saturday with 34.8C recorded at Alicante Airport, we go from summer straight back to winter with a significant change to much cooler and stormier. A lot of rain as well as inland heavy snow is expected across SE Spain over the next 36 hours.
With a trough rapidly replacing the ridge, storms have erupted.
Alicante last night…
Deep convection focusing over SE Spain this morning thanks to the cooler air aloft.
In fact the very SE corner of Iberia which soared to those incredible new March levels back on Saturday, could see the worst of the rain with flooding likely.
Not just rain but heavy snow for the southern Sierra.
What an amazing shock to the system between Saturday at 1500 hours and Monday 1500 hours!
With the high riding over top of the Iberian trough, mild air is crossing over top of the cold and bringing decent spring conditions to much of the UK both now and late week AHEAD of approaching fronts. It will also be that bit breezier the further north you go over the UK with gale or even severe gale-force winds for the Northwest Scotland as lows pass.
The up and down regime this week is courtesy of the storm and cold plunge into eastern North America.
The below jet stream/850mb temperature charts for the remainder of this week pretty much sums it up. Note the initial trough over Iberia, ridge extending into the UK with jet close to Scotland then front pushes through, jet sinks before lifting again ahead of the next and more influential low Friday.
