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 […]
Early season arctic air continues to push south after shivering a large swathe of Canada during September. The next couple of days shall see quite the punch of early season cold and wipe out of the Texas heat. Indeed cold slamming into warm means the usual potpuri of weather with flooding rain, severe weather, big […]
Like all the other southern US cities, Atlanta is well used to heat and humidity during the summer months but this year has been exceptional. After a wet spring, nights have held unusually warm with a record streak of consecutive nights at or above 60F which started early (May) and continued late (September) and in […]
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 […]
At 12.30pm CT, Hurricane Michael made landfall near Mexico Beach, FL as a top end Cat 4 hurricane packing sustained winds of 155 mph. Just 1 mph higher would have been this the first Category 5 landfall since Andrew in 1992. Michael was the Panhandle’s strongest ever landfall and 3rd strongest for the US in […]
Despite encountering shear, some dry air and even the crossing of a cool ocean eddy, Michael has continued to strengthen. Just yesterday morning Michael was a tropical storm but as of this writing, he has become a 120 mph Category 3, poised to be one of, if not thee strongest hurricane to ever make landfall […]
Back on Friday I posted on the CAG (Central American Gyre) and the potential for development. Yesterday we had Tropical Storm Michael, today’s it’s hurricane Michael and appears to be on it’s way to becoming a major tomorrow over the open Gulf of Mexico. This system has organised and intensified quickly to the east of […]
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, […]
