Winter 2016/17
A bizarre chain of ocean-atmospheric events has led to a setup you never see in November. Record low arctic sea ice has led to a weak polar vortex which in turn has held a strongly negative arctic oscillation. That then has supported persistent high latitude blocking which makes for an unusually warm arctic and unusually […]
The relentless September-like heat is being wiped out west to east and replaced with late November conditions. Many sites have went from 75F to as much as 85F only to experience snow within 24 hours. If your still ahead of the front, well enjoy the warmth! Wind blowing hard and snow falling hard this morning. Sioux Falls, […]
With the help of a northerly (arctic origin) showery air flow, several spots over the UK have woken to a fresh covering of snow this morning! Great shot from Martin McKenna of the snow near Coleraine, Antrim last night. Another great shot from Paul Kingston in Harwood, Durham this morning. Where you perhaps didn’t see the snow, you may have […]

It’s been a weird and wacky week of weather. We commenced the week with night lows of 14C and afternoons up to 17C, now it’s icy wind, rain, sleet and snow showers. Unusual? No but tornadoes? Blame a late November strength cold front driving into an unusually warm, humid air mass. Doesn’t take much within the […]
And so the remarkable stretch of record breaking warmth continues and we’re just 15 days from the start of Meteorological Winter. Most stations from the Mississippi westward have seen their warmest past 30 day stretch for the time of year on record! As for the first 15 days of November? The core of the heat has […]
This has been the SSTA profile the past few years. Very warm N Pacific. Very cold central North Atlantic This has been the resulting winter pattern for Europe thanks to the above SSTA profile. But this year with the opposite showing, this is where I think we’re going in 2016-17. A Rough Guide to the Jet Stream: […]
We have all the ingredients coming together this week to bring the season’s first major winter storm starting off Out West. However once the circulation crosses the Rockies and enters the open Plains, cold air sweeps in from the NW meeting warm, humid air from SE and along with strong upper jet stream, the system is going […]
The seesaw is ready to swing the other way as the warm air currently over the UK will be over snowbound Romania, Ukraine and W Russia by late weekend as seen from the below GFS 2m temp anomaly charts. [s2If current_user_can(access_s2member_level1)] Last night and tonight are the coldest of the season for eastern Europe, especially over deep snow cover. […]
According to a recent press release from NOAA, La Nina is officially here. This is NOT good news for a parched California/Southwest and Southern United States. The reason is of course that La Nina’s tend to favour drier than normal conditions from Central/Southern California to Carolinas. This unfortunately encompasses both ‘extreme drought’ areas and so significant drought relief during […]
