This means that we could be in for a very interesting time indeed in that regard. Of course, we could have done with seeing that northern blocking during the winter so that it could have brought us a lot of cold and snowy weather, and the fact that we had such a horrible winter in that regard makes that all the more frustrating. However, I did also predict that this would happen too late to bring any real cold weather and that there would be a lot of frustrated people on this forum as a result as I am already starting to see, going by some recent comments on this thread.

Back to the here and now


Passing troughs on Fri & Sun, then HP getting established for the rest of the GFS run through to Sat 28th March. The models are not stable when it comes to predicting where the HP will set up - GFS now says centred over the UK (not Baltic as yesterday) peak 1040mb Mon 23rd, and ridges forming in various directions from time to time so winds vary, mostly W-ly in week 1 then E-ly in week 2 but lighter than forecast earlier (no gales in the Channel on today's run)


ECM agrees and reaches 1030mb centred over UK  at the end of its run on Sat 21st. BBC last night showing a more elongated ridge from mid-Atlantic across UK to central Europe.


Ens runs cool at first, good agreement for getting milder after current dip with peaks Sat 14th and Fri 19th (the latter less marked in N) after which divergence sets in - mean near average but control run v. cold on Mon 23rd. Very dry in S but some rain in N at first.

yes, I remember theire being strong wintry periods in late March in the 70s, with one delivering 3ft drifts on the South Downs. 


Looks like something is really brewing here....what a shame it is not January!!!


I am longing for Spring now, but I think winter might well be about to start....ironically. GFS average in FI is showing a Scandinavia high and very cool temps. That is unusual. Most putabations are showing wintry weather by the 25th to 27th.

I’m not seeing much sign of anything too wintry on the GEFS. Lots of scatter but just as many notably mild runs as chilly ones producing an average just about on the long term mean. Hopefully the high will end up centred more or less over the UK giving us some dry weather. The common here is about as wet as I have ever seen it.

Hurrah! Training for my 1st marathon, and a trail at that, has not been fun on the Berkshire hills recently, loving the GEFS at present. As much as the waterlogged trails is a problem for my feet, the wind is a killer so nice to see a week or hopefully more of settled weather.

Havent done it since about November, as the ground was just like a bog, and almost impossible to get any rythm - even up hill.  a dry continental feed will do nicely with longer brighter days to bring the plants into growth.  It should help firm the ground up enough to start up the running again...


 


Got the Liverpool Half on Sunday, weather looks fairly decent, slack winds and a little damp..

As for drying out, the field behind us is still under water on our side and will take weeks to dry.

After this weekend with troughs in the westerly stream passing through, high pressure is around for the next couple of weeks. GFS still not certain on how it develops - today's version is Wed 18th 1030mb over the S with link to Atlantic centre; the latter moves N to Scotland Sat 21st 1045mb with N or NE winds developing; then to Baltic Wed 25th 1040mb with ridge to UK and E-ly winds; further E again by Sat 28th and new centre over Iceland at that time with slack LP over UK. Complex, but not the simple HP centred over the UK as suggested yesterday.


ECM similar though more of a ridge to Europe on Sat 21st which means less of the N/NE-lies


GEFS  cool-mild-cool-mild to 18th then down to 5C below normal on 21st, mean of runs recovering to normal but with plenty of scatter. Dry in the S, a little rain at first and around the 18th in the N (though just one run has a startling peak of 25mm rain on the 20th in the S).

I wonder whether it might turn out that high pressure alone is the significant factor in stopping the spread of viruses. It's long been known in horse racing that when a particular stable's horses have been running badly owing to a virus, what clears it up is a freeze-up. In this country that means high pressure being in control in winter (i.e. the opposite to the one we still seem to be in). Maybe it's as simple as a lack of wind preventing these viruses being blown about.


Anyway, let's hope the bullseye col shown at day 8 on the ECM this morning comes off.

Again a decent easterly from next weekend. -12 uppers creeping in. Even for late March this could deliver snow showers.
Perhaps this late late show is sliding in under the radar?

Just having a look at snow cover over Eurasia:


Remarkable a how much it has receded and snowline never really made it to eastern Europe either. Southern Scandinavia and Baltics are snow free - even the Ukraine and it's only early March still. Little if any snow over Alps and virtually nothing over Pyrenees! Wow. If anyone wants to go skiing then Norway is best or Maybe Turkey is best but even that looks patchy there.

While us here at Kent will (or rather, should) do well out of next week's ridge of high pressure moving in from the Azores thus bringing some welcome dry weather our way, it seems that other parts of the UK may be less fortunate with wavering weather fronts being strung through the middle part of the country. I suspect that may bring even more unwanted high rainfall amounts to Cumbria, Northern Ireland and surrounding areas by the middle part of next week.
