I notice quite a dip in 850s as we end the month ?

I like my cold spells to be long, especially if there's snow on the ground (why Jan 10 was so good; we had lying snow for 3-4 weeks)

Upgrade so easily to near clean -10C uppers with 1 mild strangler remain now and few -11Cs.  Serious cold going to hit there since 1950.  Very bad that London failed to get to -10C or below this winter which if was here we should be looking at clean -15C to -20c uppers.

I feel very sad watching that. We will never see the likes of it again. Yes, I know Feb 2018 but that was a freak event caused by the record SSW and it didnt last very long and produced only a small amount of snow.  Feb 2009 had a lot of snow but it was not very cold and there was constant melting at low levels.  The snow we had in the old days felt different.  No drip drip drip

I know it's only CFS but a signal (mirage) for a cold mid March.Looking at all models I wouldn't rule that out yet on this winter's blocking patterns.Might see a good fall of wet snow yet...

All but impossible here, I can't remember the last time there was a covering of snow on the ground after the very beginning of March. 2013 just saw brief slushy partial dustings, not complete coverings, and April 2008 was a complete miss, with just cold rain. It really is very, very hard to get sufficient cold to allow a covering this close to the coast (½ mile inland).

Before any potential mid-March fun, though, it looks like an extended period of zonality to get through first, with potential gales. This morning's GFS is typical of the output - deep lows to the NW, secondaries zipping across the UK, especially in the south, buckets of rain, especially in the west. The precipitation totals for the next 10 days are quite something! The ground here is finally drying out (thanks to the easterly we've had, and will have for another couple of days, the low dewpoint air is very handy for this), but it won't be long before grassy areas turn back to a muddy quagmire.

Here's the 0z GFS totals for the next 10 days.

WX temp charts confirm the previous retreat of cold air back to NE Europe/Russia and in week 2 show Turkey as less cold than yesterday. Just a hint of something colder directly from the north reaching Scotland in week 2. 

GFS Op - this week to Tue 25th  LP off NW Scotland dominating British weather, with S/SW-ly winds, gales esp Fri & Sun, unsettled and cool in the N, milder with relatively HP in the S. The far E of Europe has LP to start with, filling as HP settles near the Black Sea. FRom Tue 25th the weather develops zonality with troughs and ridges moving E-wards across Britain and on the the continent, one such trough Thu 27th reaching well S and bringing in some wintry air, 

ECM like GFS, but starts the zonal flow a day earlier

GEFS mildest around Tue 21st, back to norm or a bit below Tue 28th, less agreement after that but more likely mild. Rain from Tue 21st becoming heavy over the following week in the S and W.

Having said all that, neither the freezes of Dec 2009/Jan 2010 nor late Nov & Dec 2010 were a result of a SSW, and that was after years of mostly mild winters during which some on this forum questioned whether we would ever see a long-lasting spell of severe cold in this country ever again.

Local field and paths have been a little less muddy and flooded in recent weeks than they might be this time of year but just as the sun's potential drying power increases, it looks like we're back to wind and rain again.

The former stance is IMO the more realistic one to adopt as it always leaves the door open to a degree of doubt, even if it is a fairly small one.

I can well remember around 20 years ago, both before I joined TWO and then after I joined in 2006, that on this forum there were a number of people who believed that severe winters, or even severe spells lasting a few weeks or so, couldn't happen again in this country. At that time I had started to think that perhaps they had a point after a run of mild/very mild winters for several years up to then. Winter 2009/10 and December 2010 both showed that they can still happen even if the chances are reduced compared to times long past, and even though we are 15 years on from 2010 I still don't believe that anyone can say for sure that severe winters or even long lasting severe spells are definitely consigned to the history books anymore than was the case prior to 2010. 2017/18 was I believe colder than average if not a severe winter in general terms, and although not technically a winter month, there was the unusually cold March of 2013 as well which was only a year after one of the warmest Marchs on record in this country.

Seems this Autumn isn't quite done with us just yet as we go into the last week of not just February but meteorological Winter.

This climate of ours really does test our patience a lot of the time.

(And FWIW down here, I'd say autumn finished in early January, as we had 2 weeks of cold weather with just a brief mild and windy blip, then it's been generally coldish until now. Spring starts later this week as the warmth returns).

Talking of gales, the GFS has been ramping up Sunday's winds through the day - starting in the 50s with the 0z, going up to high 50s in the 6z, and now reaching a delightful 62mph with the 12z. Honours are split so far this autumn-winter season so far, with MetO and GFS both being right 3 times each in terms of their initial wind forecast strengths. The MetO raw couldn't be more different than GFS, with a gentle SSW'ly breeze, gusting to 12mph... just 50mph lower than GFS has at the same time!

WX charts - temps much as yesterday with much milder air spreading across all of Europe from the SW over the next two weeks, and freezing conditions restricted to E Russia and N Finland. Rain for the far W in week 1, most of Europe dry, intensifying in the west in week 2 and some moving into continental Europe. 

GFS Op - dominated by Atlantic LP in three phases (1) LP off W Ireland now bringing SW-lies (esp strong Sun 23rd) and mild conditions  until Tue 25th (2) this LP moves to the Norwegian Sea and sets ups a zonal flow, W-lies with troughs and ridges crossing Britain to Sat 1st (3) more direct effect on Britain as LP crosses Scotland 980mb and affects the rest of Britain Sun 2nd  before a very deep LP S of Iceland 945mb brings in some rather cold air with secondaries in its circulation moving rapidly across England.

ECM - similar to GFS but more of a S-ly flow at first

GEFS - very mild for this week after a cold start in the N, back to norm for a few days from Tue 25th before ens agreement breaks up but most runs not far from norm. Rain from Fri 21st onwards through to Thu 6th, very heavy at times in the W, not as much but continuous in the SE, sporadic in the NE with the heaviest on the 21st, 24th, and then later on

Happy to see a promising signal has appeared at T+192-T+216h. We seem to initially see a weak deep arctic high migrate south into greenland. Although this high is weak, it is strengthened by deep WAA from Canada by T+216. Fairly strong signal for this across all the models.

Here's an example from the 0C isotherm chart.

UserPostedImage

Little pockets of cold and mild air as mixing determines the temperature more than the airmass. Its going to be an absolute forecatsers nightmare this weekend as we have a continuous strong cold surface flow interact with milder air aloft.

If we get enough frontal activity expect every possible preciptation type. I imagine sounding profiles could be extra extra wierd, perhaps we might see some double warm noses!!!

On Saturday, a front came up from the south, entirely unforecast by the BBC or anyone else, as far as I could ascertain - and dumped a heavy (albeit wet and drippy) snow fall on Norfolk and Suffolk that lasted 4 hours, of increasingly heavy and fluffy snow, which eventually settled and deposited 1.5 cm on my lawn, which was still there the following day - a bit thinner by then, at just 28m ASL. My hat is off to you sir....

Its the first snow I have seen here for 3 years.
