That's the reason why Spring is my favourite season; still comfortably cool to get through DIY projects during the day and for sleeping at night but with increasing light levels so it can still look pleasantly cheerful whenever the sun is out (like right now this morning).

Hence the latest runs are quite pleasing to my eyes and am happy to bank it.

Looks decent enough very dry it's already a dust bowl here .  We went on an Easter egg hunt with the kids at a local farm yesterday and the ground was baked hard a remarkable turnaround from the waterlogged conditions we had just a few weeks ago.

16-dayer showing a gradual warm-up (but don't get too excited) and very little rain - perhaps a bit more along the S coast in week 2


GFS shows HP moving in to Scotland and ridging to Norway until Fri 23rd but with a  a cold pool over the near continent which may keep the S cool with E-lies. After this the HP departs to Greenland and LP over W Russia gradually extends influence westwards, finally depositing LP 1005 mb Kent Wed 28th


GEFS shows gradual warmup with good agreement to norm by Wed 21st after which much scatter; mean still near norm but both op and control as much as 10C below norm at times towards end of run Wed 28th. Not much rain; generally best chances after 21st and a few runs with big totals later on esp  in S.


ECM is similar to gfs but keeps the HP centre further S, over Wales, and has a hiatus Tue 20th where it weakend before re-establishing a link to norway

It was drying out nicely here (from a mountain biking perspective!) but this morning's snow will turn everything muddy again. I guess it probably only amounts to 5mm of rain or so, so not too much to worry about.

I wouldn't be suprised if we get another arctic incursion at the end of the month.


Strong signal for another greenland high.


The issue is that with a rapidly weakening polar vortex it becomes difficult to get that pressure gradient necessary to advect colder air south.


However until the middle of May the arctic maintains a cold enough airmass to provide snow easily to lowland britain should such a (very rare) synoptic situation arise.

A general warm up towards the weekend and beyond. The nagging nor’easter keeping a check on temperatures but feeling pleasant in the sunshine in the lee of buildings and high ground.

Bone dry.

The 6z (certainly the op and supported by the mean) shows more northerly incursions in FI.


HP dominating though so very little rain again

GFS 12z looks much warmer though some of the High Pressure cells wallowing about look rather implausible.
Much warmer into Western Europe especially.

Yes much better (warmer) output tonight all round including both GEM and ECM.

16 dayer shows W Europe slowly being released from its current widespread below average, with, in week 2, the blue (below 0C day-night average) disappearing from the Alps and Norway for the first time this year, and light greens* (10C average) across continental Europe and just about into SE England. Rai mostly through the Med, and later NW Britain.


GFS shows HP coming up from the SW and ridging across to Norway by Fri 16th; slight hiatus on Tue 20th after which new HP cell very much centred over UK (1035mb every day Wed 21st to Thu 29th). The fringes of the HP may sporadically produce either a bit of dampness for NW Scotland or colder NE-lies for SE England. The averages shown by GFS probably conceal warm by day and cold by night. Gardeners beware!


GEFS temps climbing from present cold to a degree or two above norm in the S by Fri 23rd (N England perhaps 2 days earlier, Scotland 4 days earlier), after which agreement breaks down; mean close to norm, but unlike yesterday op & control are warm - however counterbalanced by some quite cold runs. Minimal rain, even at end of period where some was shown yesterday


ECM varies from GFS in positioning the HP cells: the first is further SE so some SW-ly gales for Scotland Sun 18th; and the second further NE so general SE-lies by Fri 23rd.


 


* Light greens, I think; bring green colour-blind, the map at this time of year is rather a confusing tangle of various browns as I see it

Same here.  The field headlands were baked hard and dry when I went out for a walk on Sunday. Looking at the GEFS rainfall prediction of very little (London), that's not going to change for most of the rest of April.  Seems as though I'll have to start watering the garden again very soon.

Some signs of something warmer (or less cold) are showing. It is all very gradual though. Where there is a chance of an airflow off the continent I tend to look at cities over the channel from us. Paris looks likely to warm up into the high teens early next week but Amsterdam stays in the mid teens. Certainly the wind direction over the next couple of weeks will be critical. Anything north of due east is likely to keep temperatures suppressed, if we can get a more southerly drift we could tap into some warmer continental air.
