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

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 […]

The noteworthy 4.5 inches which fell Thursday 2nd January was the city’s biggest snowfall since February 1, 2011 when nearly a foot fell. As you can see from the below graphics. More snow fell […]

Big variation on New Year’s Day with -30 Minnesota to 80 in Georgia, 1st snow for Tucson in 6 yrs

There was two very different air masses separating the US as we commenced 2019. While looking and feeling like winter across a large swathe from Montana to Minnesota and from Arizona to Texas and points in between, it was more like spring from Florida to Rhode Island. On the final day of 2018, temps were […]

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?

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 […]
