Whether you love weather, cold weather or both, we all get excited at the thought of a sudden stratospheric warming event. No question it’s a truly spectacular event and awesome to watch on the many incredible graphics we have at our finger tips these days. While they only occur every so many years, there is […]
We’re ending January with a stratospheric warming event as temperatures have risen 60C at within the past week at 10mb over the Arctic. This is within SSWE criteria. AO will go negative in response! Not related but it was a cold start to this morning over Highland Scotland with -10C recorded at Braemar but in contrast, it was 20C warmer on the SW coast of England. […]
In the wake of wicked storm Henry which produced 100 mph winds on the exposed but low lying Tay Road Bridge and 149 mph over Cairngorm Summit Monday, northerly winds on the depression’s rear has helped force exceptionally cold air within the lower stratosphere (50,000+ feet) with the southern extension of the polar vortex dropping down over the UK. Clear, cold […]
As your well aware we have a big system system rolling across the country from LA to Lansing this week that’s likely to produce blizzard conditions from Denver to Des Moines. In it’s wake we get the first of 2, maybe 3 waves of Arctic/Siberian air. According to the latest run of the GFS, the 2nd wave looks strikingly similar to […]
The seeds to a warm, wet, zonal December have been sown. We have an on going cooling of the polar stratosphere at all levels which will bundle the coldest air within the arctic circle through much of this month. This draws warmer air from subtropics into mid-latitudes and powers a stronger than normal jet stream across Pacific, North America, Atlantic […]
Before you read, I would encourage some caution because this is not me forecasting a late November cold outbreak but more showing you some optimistic model output. More what the atmosphere may be showing and where it may want to head ‘periodically’ through the upcoming winter season. What’s quite interesting is the models didn’t really […]
No question, it’s been mild to warm on the East Coast with snow cover shrinking rapid. However, the cold pattern is coming back and here’s why. When you’ve got a strong phase 7 MJO, and the AO/NAO are heading into negative territory with abnormal warm water up the West Coast, you just know where the heights […]
The wind stream map off MeteoEarth shows just how busy the North Atlantic is today. Four lows are spinning and three are producing hurricane-force gusts. It’s all eyes on the high building and expanding over Scandinavia as this will turn our flow easterly over the next 24 hours. These chilly easterly winds will pick up […]
The storm is whipping pretty good just now here and for some, it’s downright damaging! Top gusts have been clocked at 111 mph on exposed Aonach Mor summit, located E of Fort William, 105 mph on Cairngorm and even down in Cumbria, gusts of 101 mph have been recorded on Great Dun Fell. The A9 linking Perth with Inverness […]
This week isn’t going to be all that warm but there is undoubtedly a ‘warming trend’ following the frigid open to the month. Despite all the talk about warmer weather… here were this morning’s lows. 1044 high over MN-IA tomorrow. Here comes that warm-up.
