RARE SUMMER FROSTS SWEEP THE UK AS RECORD JUNE COLD SETS IN

JUNE 22, 2021 CAP ALLON


Western Europe has been suffering yet more unusual chills of late, adding to the historically cool year so far. For me in Portugal, for example, daytime highs have held some 10C to 12C below the seasonal norm for the past week.

Anomalous heat may be lingering in Central/Eastern Europe (due to it residing “under” a low solar activity-induced meridional jet stream flow), but a brutal Arctic chill is dominating nearby, in Western nations (which are currently “above” the jet stream).

Following some very low maximum highs on Monday, June 21, the morning of Tuesday, June 22 has seen harsh summer frosts sweep the United Kingdom.

In England, a low of -1.4C (29.5F) was logged in Ravenseat, North Yorkshire.

While in the Scottish Highlands, readings of as low as -3.3C (26F) were registered, which made for the UK’s coldest June 22 in recorded history, annihilating the previous benchmark of -0.7C (30.7F) set at Braemar, Aberdeenshire in 1999.

Additionally, this morning’s reading was also the UK’s second lowest ever recorded this late into the season.

Not since the -3.3C (26F) of June 24, 1957 has a Britain suffered a reading this cold, this late.

Britons have been battling an incredibly cold 2021.

The months of January, April and May were all significantly below the Mean Central England Temperature.

April anomalies finished a staggering 1.5C below the 1961-1990 climatological average used by the UK Met Office (a historically cold era btw), which led to the UK suffering its coldest April since 1922.

While May, 2021 was one of England’s coldest May’s in history, in record books dating back to 1659:

Looking ahead, Western Europe’s unusual summer chills aren’t expected to end any time soon.

As revealed by the latest GFS runs (shown below), the cold is actually forecast to intensify and spread eastwards as the week progresses, infecting France, Belgium, Holland and Germany by June 23, and nations as far east as the Ukraine by Friday, June 25.

Furthermore, the anomalous Arctic invasion is also predicted to deliver some exceptionally rare summer snow to the Alps as well as the northern Spanish Mountains between June 23 and June 26:
