Beneath the core of a super cold arctic high, the temperature plunged to a bone-chilling -55 degrees at Rabbit Kettle, NWT this morning while many surrounding locales stretching from eastern Alaska to southeast Yukon dropped below -40. That’s a January-like air mass even by this typically cold, snowy region at this time of year and this […]
After today’s strong winds over Ireland, Northern Ireland and the UK, high pressure builds in from the Atlantic and will settle things down. It will initially turn colder once again tomorrow into the weekend as cold air remain in the mid and upper levels but into next week, the high continues building, drawing milder air […]

Scotland The winds sure have been blowing out there this afternoon, the good news is they should ease through this evening and overnight but as skies clear and winds fall light, so will the temperatures. Watch out for ice tomorrow morning, especially in the Highlands. Lows -1 to 4C. Thursday will be a better day with dry, […]
We have some truly mid-winter like air right now up over Alaska and the Yukon with readings in the -40s this morning. Even some 1-1,500 miles to the south, Calgary didn’t make it out of the 0’s today which show the extent of this arctic air mass. The core of that -40 air will dive into the heart […]
Well both GFS and ECMWF unsurprisingly have turned warmer for next week with the cold and trough shifting east as the NAO/AO look set to bounce back in a positive direction. This week was never going to hold. We turn windy tomorrow as a deep low slides over top of Scotland’s north coast before dropping south […]
Scotland After a bright but cold day, temperatures are dipping but as the temperatures dip back to freezing, cloud is pushing in from the west and eventually winds will pick up this evening and overnight. Lows dip initially to between -1 and +1C, colder the further east you are but by midnight, it should be up […]
Last week’s Midwest and Eastern cold blast hit while both the NAO and AO was strongly positive but given that those indexes are heading towards neutral and negative, it’s plausible to believe what both the GFS and ECMWF are showing for the US late this week into next. While the last blast was a chilly one, that would […]
A frontal system is progressing south over the UK, pushing out the mild and pulling in the coldest air mass of the season so far. Scotland turned very bright and sunny this afternoon as cold air flows south. Here’s a late afternoon view from space showing the cold NW flow progressing south over Scotland, blowing in from a […]
We have a dangerous severe weather situation unfolding this afternoon and tonight over the Ohio Valley as a deepening surface low pushes northeast over the Great Lakes with warm, moist air flowing up from the Gulf as well as the Atlantic while cold, arctic air flows out of the northwest, on the backside of the low. A strong 70kt low […]
