Looking for warmth? We're about 4C above the April mean!

WX temp chart shows only a small patch of freezing weather over N Russia, but a cool lobe extending quite a long way south from this; in week 1 over NW Europe but in week 2 further east displacing the very warm weather near the Urals (see snowmelt problem in 'Unusual weather' thread). For Britain, on the edge of the cooler weather in week 1, temps at first near norm, but a hint that some milder weather from Spain will approach the south in week 2.

GFS Op - winds going round to a brisk SW-ly under the direction of 1030mb HP over France, declining after Sat 13th as LP runs SE-wards over the Northern Isles and into the N Sea with brief N-lies to follow. By Wed 17th HP has re-asserted itself and becomes centred over Britain 1025mb, only to give way to a shallow LP from the north 1005mb Tue 23rd covering Britain, followed by a weak pressure rise.

ECM - similar to GFS though the LP Sat 13th promotes a deeper trough over Britain as it passes by. The last frame (Sat 20th) suggests that the HP may give way to a milder LP from the west, not north.

GEFS - Quite generally mild/very mild to Sun 14th, when a sudden drop to cool with very good ens agreement, followed by a few days a little below norm with moderate agreement, and from Fri 19th mean stays near norm amidst increasing disagreement (op & control cool later on). Very little rain in the S, not much more in the north after a a wet couple of days around the 14th, also bits and pieces cropping up in far NW.

While acknowledging how cold it's been in much of Scotland (they pinched our easterlies! 😉), I do wonder how much moaning would ensue if we had even an average spring month for once down here, let alone a cold one!

...and the wildlife certainly isn't suffering down here. At least 2 pairs of pigeons are nesting in the old plum tree in my garden, and when I was mowing the lawn earlier the garden was buzzing with bees, hoverflies, normal flies and a few butterflies. It's been so warm, in fact, that everything seems ahead of itself!

Slightly off-topic, but I wonder how much the SWW(s) have caused this spring’s unsettled conditions (southerly tracking low pressure). Hopefully there are tentative signs that this pattern may be ending or at least easing.

It could be that the recent prolonged SSW has prolonged the pattern beyond its natural ending, but we'll never know for sure! What I do know is that zonal winds at 10hPa/60N rebounded and are, for the first time in months, a fair bit stronger than normal. The "final warming" will be a fortnight late this year which, in theory, means the "European monsoon" would be pushed back further into June than normal... but who knows these days, the old rules no longer seem to apply.

Well the GFS Ops 6z shows a rare thing these days. An anticyclone which moves steadily west to east across the UK next week before declining and moving into the continent. If it pans out it will allow for the classic gradual transition from cool/cold to mild/warm then back to cool/cold. 

I'll believe it when it is much closer in the timeframe .....

And the UK's climate is getting warmer, of course, not colder, as the lack of snow and repeated heat records show... YOUR view of it is colder, as you're comparing it to the SE. 😉

Anyway, the models continue to show high pressure having more of an influence... at this rate, could well be a drier than average month quite widely down here (turns out the 7mm from the storms the other day was very localised, less than a mm just a few miles east or west).

The last 7 months or so, starting with that remarkable heatwave in September, have been staggeringly warm. There can't be many warmer like for like periods in the record .
But it's been accompanied mostly by abnormally grey skies and high rainfall plus a lack of individual very warm days which makes it much less noticed and tabloid friendly !

WX temps continue the theme of a lobe of cooler air pushing south between something warmer moving north, both to the west (over Spain) and east (over the Caspian). The difference from yesterday is that this 'lobe', currently over Germany/ Poland moves westwards in week 2 to affect Britain/ France/  Germany, rather than eastwards. To match this, the warmth in Spain makes no progress but east of the Caspian it is insanely hot for April. The Atlantic and nearby areas are fairly dry (bar N Scotland) and the the Caspian area extremely dry. In between there are patches of rain over various parts of continental Europe with the heaviest in week 2 in S France.

GFS Op - Current HP over France moves W to mid-Atlantic with wind direction for Britain going round from SW to W to NW to N by Wed 17th. Pressure remains high to the W of Britain through to Wed 24th while LP develops over Belarus, so some chilly winds off the N Sea. The HP then retreats to Greenland and an extended trough develops from Norway to S France between that and HP intensifying over Russia. Hence strong NE-lies for all of Britain after the 24th.

ECM - begins to differ from GFS at the end of its run with HP after Wed 17th moving in from the Atlantic, rather than standing off,  to become centred 1035mb Irish Sea Sun 21st, and significantly deeper LP over Belarus.

GEFS - temps dropping sharply from mild to cool Sun 14th (min ca 4C below norm on 17th), and only recovering slowly, slower than shown yesterday and indeed the mean never quite gets above norm through to Sun 27th. At that time the op run is coldest and about 8C below norm, and supported also by the control run in the N. Dry for the most part throughout the period esp in SW, occasional small rainfall peaks further N and W.

Certainly not before time either. The wet period we have had since last summer/autumn has at times been like 2012 all over again, and the very wet period we had then lasted a similar length of time from what I remember.

Still dull and not at all spring like on the south coast. Seems like we’re stuck in a forever November. Very wet, often windy, the sun only appears for brief spells, lots of low cloud and mist. 
Still holding out for the first high teens Celsius, let alone 20!
pretty astonishing for mid April in these ‘modern times’.

WX temp summary: after a few days in which a broad area of cooler weather has pushed well south across NW Europe, there is some relaxation. Week 1 as before with that cooler weather in place, and some warmth to east and west of it; week 2 milder weather begins an advance from the SE on a broad front, albeit modest and patchy, reaching Austria and Poland. Spain is cooler but the Caspian still ridiculously hot. Rainfall over much of Europe in week 1, Spain and England excepted; in week 2 the focus is on France and the western Med, some spilling over into England while Scotland is drier. (The rather cold weather noted under GEFS later on does not show up distinctly , Britain just staying cool)

GFS Op - as yesterday, HP over France moving out into the Atlantic with winds backing from SW round to N by Wed 17th with Britain on the edge of LP covering much of NW Europe. The Atlantic HP then moves E-wards across Britain to cover all but the far NE 1020mb Sat 20th but declines leaving Britain in a col between LPs in Baltic and Biscay. The Baltic end of this trough takes over, at first projecting NE-lies into Britain and then moving SW-wards to reach Holland 1005mb Fri 26th and sticking their with its imported cooler air affecting England while HP south of Iceland offers fine weather for Scotland.

ECM - something like GFS until Wed 17th though the concluding N-lies for this period are stronger under the influence of a better-defined LP moving from Faeroes to Denmark Mon 15th/Tue 16th. The subsequent HP remains further to the west of Britain to Sat 20th with a N-ly cast to the weather, and only at end of run Mon 22nd does the HP begin to move E-wards with the LP then setting up over Ukraine rather than the Baltic.

GEFS - mild dropping to cool Sun 14th and slowly recovering to just below norm in the SE Sat 20th even somewhat above elsewhere, esp in the N, after which the modest amount of agreement between ens members disappears. The mean then stays a couple of degrees below norm throughout. By Fri 26th both op and control are the coldest at about 7C below having been milder earlier. Small amounts of rain at any time generally.
