Glasgow, Paris, Brussels, Amsterdam see 1st snow but why no North Atlantic/Greenland block? Blame the MJO!

Glasgow, Paris, Brussels, Amsterdam see 1st snow but why no North Atlantic/Greenland block? Blame the MJO!

Many parts of Scotland including myself woke this morning to the first blanket of snow ahead of potentially the coldest night of winter tonight. However, many may be asking, what happened to the ‘beast from the east’ or Greenland block? After all our weather continues to come in from the west. Instead of this… We’ve […]

A ‘seasonable’ January chill: Assessing the UK snow threat this week

A ‘seasonable’ January chill: Assessing the UK snow threat this week

Well it’s safe to say the cold which was expected to intensify this week into the upcoming weekend is not going to show and in fact it turns milder not colder by Friday. On a plus, it’s a temporary push of mild. The reason? That storm system exiting Canada has not forced sharp height rises […]

Snow chances on the increase for UK but where, when, how much?

Snow chances on the increase for UK but where, when, how much?

We all know it’s turning colder as a direct consequence of the late December sudden stratospheric warming. In fact as our tropospheric winds reverse from west to east, the stratospheric winds are returning to a westerly as the vortex up at 10hpa begins to recover. Thankfully for cold weather lovers like myself, this cold spell […]

Wild start to 2019, Record 1045mb UK high vs 956mb Finland low, 19C Iceland, -23C Greece, 10ft of snow for Austria

Wild start to 2019, Record 1045mb UK high vs 956mb Finland low, 19C Iceland, -23C Greece, 10ft of snow for Austria

There’s an argument to be had. Is the extreme, meridional upper air pattern over Europe to open 2019 a response of the sudden stratospheric warming which peaked around Christmas with split occurring around January 1-2? I believe there’s at least some sort of linkage given that one of the two, maybe three split daughter vortexes […]

Huge snowfall buries Alps as upper level winds turn easterly allowing Siberian air to head westwards

Huge snowfall buries Alps as upper level winds turn easterly allowing Siberian air to head westwards

The much anticipated colder, snowier pattern has emerged and progresses south, southwestwards into central and southern Europe. Stopping it from spreading westwards is a very strong ridge anchored over the British Isles which reached record strength as we greeted 2019. This pressure pattern has resulted in a rather mundane Christmas to New Year period here […]

SSWE has occurred, we now await split & downward response, CFSv2 sluggish with -AO/NAO through Jan 25

SSWE has occurred, we now await split & downward response, CFSv2 sluggish with -AO/NAO through Jan 25

The sudden stratospheric warming has now crucially progressed across the pole and headed towards the Davis Straits as we entered 2019. A split in the vortex is expected over the next day or so. Now we all know that there’s a delay or lag between the initial SSWE at 10mb and by the time the […]

Cold 2nd half to Winter 2018-19? MJO expected to enter cold phases as SSWE causes vortex split!

Cold 2nd half to Winter 2018-19? MJO expected to enter cold phases as SSWE causes vortex split!

The pattern has been mild across most of the continents of the Northern Hemisphere with the aid of a continued amplified MJO progressing through phases 2,3,4 and 5 which supports a neutral to positive AO/NAO. Though NOTHING is certain until we see the pattern evolve, there are more favorable atmospheric drivers/signals/components coming together which supports […]

A Rather Boring Christmas to New Year week but the calm before the cold?

A Rather Boring Christmas to New Year week but the calm before the cold?

Well I hope you all had a wonderful Christmas. Now we’re in that gap between Christmas and New Year festivities and the weather is not particularly exciting to say the least. No cold, no snow, no storms but parked between weather systems which aren’t moving that much due to a relatively slow upper flow. Briefly […]

Europe January 2019 Outlook

The month of December has panned out pretty much as expected, predominantly mild, often wet and driven by a mainly +AO/NAO. In the 30 day animation below, you can see the initial blocking then return to negative heights across much of the arctic (+AO) which has led to mild over the continents but note the […]
