Rest of Europe
The Eurasia snow cover is rather bleak this year. https://twitter.com/MarkVogan/status/1053061621411655680 This year is the polar opposite of 2016. https://twitter.com/MarkVogan/status/796417042907856900 They say a big snow cover in October can enhance high latitude blocking during the winter providing southward incursions of polar air into the mid latitudes, particularly eastern North America and Europe. I’ve shown the below […]
After a pretty active first 20 days of October with flooding rains and named storms, the models are hinting at a colder pattern developing on both sides of the Atlantic to end October/begin November. A strong 1040mb Azores high is currently centred WSW of Ireland. This will feed most of the active weather over top […]
It was one of those oddities of the 2018 season, you get them now and again where they go one way, the other way, up and down and just keep on going. The eventual demise of Leslie was colder waters off Portugal but like Vince in 2005 and Ophelia in 2017, Leslie defied the laws […]
According to the Met Office, the central pressure within Storm Callum dropped from 986 to 938mb within 24 hours. That astonishing 48mb drop 24 hours made Callum an ‘atomic bomb’ cyclone, doubling the 24mb within 24 hours drop to constitute a ‘weather bomb’. It also broke the 1979 record of 939mb for early October UK […]
The week started soggy and will end soggy but in between, well it was more like summer again. When you get a stalled conveyor of subtropical moisture piling into windward upslopes of the West Highlands, you know flooding will be the result. For us here in the UK, these upper level rivers typically stall, running […]
As stated at the end of last week, the west Highlands would be under under the gun for a significant multiday rain event which continues this Monday evening. With a near stalled moisture plume connecting a hurricane and the sub tropics with Scotland, you know the totals will mount up. It’s not been one solid […]
We saw a largely undisturbed period of fine, dry, warm anticyclonic weather across many parts of the Boreal North during the height of the summer. Likely driven by the lag of the 2016 Super El Nino, favorable MJO phases and a lack of Atlantic tropical activity. However, since the tropics came to life in August, […]
As we continue to see the ups and downs of the current pattern, our attention is turning to Hurricane Leslie and the complexities which surround her influence on the UK and the wider West of Europe next week. A lot can change and we know the models don’t handle tropical interaction well but there are […]
Dr. Jeff Masters · September 29, 2018, 8:24 AM EDT A deep area of low pressure with tropical storm-like characteristics that formed in the eastern Mediterranean Sea on Thursday night made landfall in the southwest Peloponnese of Greece on Saturday, with the center crossing just west of Kalamata. The pressure fell as low as 989.3 […]
For several days now the models have been in good agreement on the development of a warm or semi warm core low over the central Med basin off Libya and is expected to intensify as it’s projected to track across southern Greece this weekend. These relatively rare features are known as Medicanes or Mediterranean hurricanes. […]
