12C toasty?

As you say, the ECMWF chart isn't exactly "toasty". Reading has a high of 13C on that day according to the ECM ensembles, with the median being 11C (edited as I was looking at the 9th rather than day 10 initially).

Perhaps a northerly can spring up out of nowhere. Would be nice to get a proper frost before its too late. But it looks like the end of the rain for the foreseable down here anyway

I'm perfectly happy with 10-14*C by day and low single digits by night in the first half of March - that's around the long term average or just above, and can be very pleasant in sunshine and light winds.

...hence light winds and sunshine are the details I'm now concerning myself with;

 

We're currently seeing a strong signal for high pressure to park right over the UK or just to the east. Both of these locations favour reasonable temperatures, and the latter can be decent for sushine too depending on the air source

We don't want an air source from the east, as that interacts with the North Sea to produce low cloud that tends to get well   inland at this time of year. So a SE or S flow is preferrable.

Thankfully that's what the models are firming up on for days 5-6, but beyond that, GFS shows more of an easterly flow while ECM shows more of a SE'rly - so there's the possibility for a less than ideal setup to evolve there, but we still have a strong player voting againt that, as does GEM.

 

What about the winds? If the Atlantic pushes too close, we'll have a breezy spell for days 5-6, otherwise light winds look to prevail. Trouble is, the models have been known in past years to place high pressure too far south in the mid-long range, then correcting it a little way north, resulting in breezier conditions for the south at least - something to keep an eye on.

For those who've wondered, yes it is looking rather similar to how 2012 did during the same month.

Having said that , the Pacific Ridge is some way further east this year, and that can be an important player for the UK. We also have more of a positive PDO signal and signs of a strong El Nino as opposed to the very weak affair in 2012 that never really got going.

Given the time of year, that is one very warm high. In general, TT1000-500 do not get so far north on such a widespread basis until the middle of May. Models might be overdoing the warm advection, but it gives an indication that some places may see top temps in the mid to high teens during the next couple of weeks.

Should give a chance for rivers to discharge, but with the airflow generally southwesterly, RH's expected to be high for early Spring, so the real drying out process is likely to be painfully slow.

Lovely spring charts and at least very much welcome prolonged dry weather to allow flooded areas to recover.

After a bit of a wobble yesterday, looks like we're back on track with high pressure taking over next week.

Enjoy.

It goes without saying we deserve this after what has been a very long, tiring and difficult winter (autumn).

Anyway - more to come though in the meantime.

IS this set up likely more than not to cause dense fog.

The reason I ask is I have to catch a flight early in the morning at southampton on 15 march

thanks

Someone's going to have egg all over their face on Sunday... Maybe

Who was slating poor Ally Pally a few days ago over him suggesting 18 degrees this weekend & beyond?

APS may well be due an apology.

JMA going for the rise in pressure next week, possibly sunny pleasant days and chilly nights, quick drops in temps after sunset.
