I can see your point Steve seems more obvious when you look in panel mode VVVVV,but as Jacko said lets see if its maintained.

This is creeping up on us. . Nothing exceptional at the moment but the signals are there.


No chart available for the selected hour. Many charts start at 3 hours ahead, so if you have 0 hours selected try stepping forward or selecting a later hour.

From IF


The new parallel (HRes) EC is repeatedly verifying best of all suites lately and albeit running the trend at base of clusters (plume below, 12z, Reading), it nonetheless matches well the colder transition in the sister EC Op. The EC snow signal (by T+210 across much of UK away from the SE, S coast and SW peninsula) is, of course, highly unreliable at this range anyway so not worth posting here. And thus by definition, anything shown by GFS at that range is even *more* unreliable, but that's an old and now wearying story.

With high SST's it's more likely to be more cold rain with the odd spell of wet snow during the next two weeks, below average temperatures yes but a cold, snowy spell No.

The mean 850T for London drops below -5 for only the second time this winter (projected mean at +5 days and over):

Decent clustering as well. Having given up on this month I might have to have a look at the slider scenario next Thurs in more detail over my kale and pear smoothie in the morning 😉

The Atlantic goes quiet and so does this thread. I guess it is sods law that there is no real cold to tap into with some of the charts being thrown out in the longer term.

IF's response to this post


In fact the more likely pattern change is the Azores being displaced east for a while, into a Euro high and the UK settling down under a positive heights anomaly. The GEFS at D16 hinting at this and CFS on board week 3 and 4:


WAS


.in total contrast to the output from both GloSea5 and EC Monthly, which agree on a cyclonic theme throughout March, generally well-amplified/potentially blocked and with flow between NW-N and occasionally NE'ly.

disappointing downgrades this morning with the positioning of the Icelandic shortwave, and the UK staying on the mild side of the jet

Yes there are a lot of colder looking charts and ensembles this morning, been building up for a couple of days. Will be interesting to see what verifies, although automated forecasts are showing some of our coolest temps this winter from Tuesday onwards

Not a warm outlook although it looks like a springlike weekend for the south if it stays dry 


Beyond that cool and largely unsettled.

With March looking likely to feature considerable high latitude blocking but with unusually little in the way if deep cold pools to work with, in wonder if we might experience some truly bizarre events.

Imagine a low tracking into Europe and moving relatively warm, moist air our way with unusually little modification. We could see an April/May like scenario of clammy air and downpours.

Now hold on a minute ECM, I was talking about March not the end of February! 


Some pretty extreme goings on with this low so worth giving it a few more runs in case we see better alignment to instead bring across some of that cold air from the E/NE. GFS has a go around day 10 prior to the usual 'FI reset' that seems to be occurring in force these days.
