The wet pattern continues for much of the UK with the Atlantic still firmly in charge as forecasted. This soggy pattern looks likely to remain from now up until Christmas, what happens after that remains to be seen. As you’re probably aware by now, I have called for colder late December onwards and the models […]
As we head into mid December the pattern is shifting. After the weeks of warmth up in Alaska and cold across much of the Lower 48, we about to see a switch with +AO/NAO. The big flip comes this weekend into next week as heights crash over AK/N Pacific while Pacific winds begin to sweep […]
The UK has been separated by two quite different air masses over the past 24 hours. Wednesday began with -7C in Aviemore but +13C in Cornwall, Devon, Dorset and really through the day it didn’t change much with the south peaking at around 13-14C whereas northern Scotland struggled to get above freezing all day. In […]
The latest low crossed the central US over the weekend with a distinct warm and cold sector. Heavy snow fell in a swathe from Nebraska to Wisconsin while further south and east, warm, humid air fueled severe weather as far north as Illinois. https://twitter.com/DevinWxChase/status/1069422577225998337 On the cold side of the front, upwards of a foot […]
A record strong and prolonged +NAO between May and August helped drive one of Europe’s hottest summer’s in the last 100 years while Greenland shivered it’s coldest since 1997. The cooling of the North Atlantic has almost certainly helped cool Greenland’s summers down and helped enhance this past summer’s deep Greenland trough and Europe ridge. […]
As we commence December and meteorological winter 18-19 tomorrow, the next surge of arctic air looks set to drill down the eastern side of North America early next week. This in turn will strengthen our predominantly zonal Atlantic jet thanks to the NAO going back neutral which means don’t expect an end to this wet, […]
November 2018 is hands down coldest since the benchmark November of 2014. While 2014 may have been colder than November 2018, several Midwest cities and some spots over New England have seen their snowiest start to a season or snowiest November on record. For the season to date, it’s been the snowiest since the big […]
Wind and rain is in firm control of our weather to end November and commence December. Lot’s of ‘cold talk’ of late and wishcasting but with the NAO going positive and polar vortex core leaning towards Greenland/Scandinavia, there’s no sign of anything other than an Atlantic pattern for NW Europe through the next 10 days […]
Over the Thanksgiving holiday, one of the coldest November arctic outbreaks descended upon the Northeast and Mid-Atlantic. Not only was it the coldest Thanksgiving day/night for many, it was also the coldest weather ever recorded in November. In order to break monthly cold records which have stood 100+ years, Canada needs to have an expansive […]
I’m just heading off to the hills but wanted to share a few thoughts on the return to wetter, windier and somewhat warmer. With the increase in thermal gradient over North America, our trans Atlantic jet is strengthening and as a result we’ll see the return to a more active pattern this week ahead. As […]
