UK Outlook for Friday 19 Jun 2009 to Sunday 28 Jun 2009:

The weekend is expected to be unsettled across the North with a good deal of cloud and outbreaks of rain or showers. The showers may extend a little further south into central parts but will be lighter and fewer. The South likely to remain dry with variable cloud. Into the week sees the weather becoming generally dry and settled across all areas. The wind, mostly from the Northwest, brisk at times in the North will keep the temperatures near normal. Further south is expected to be a little above normal and may even be warm in places. The dry, settled weather is expected to continue through the remainder of the period in the South, with the North returning to more changeable weather.

Posted by Glacier Point, a real technical expert in meteorology, over on Netweather Model Output diuscussion forum today :

A lot of uncertainty as to the exact position of the high pressure t120+ which will have big influence as to how hot or more seasonal t144-t240 gets.

All global models put up a buckling of the jet in the western Atlantic late next week which throws a ridge into the eastern Atlantic / western UK. Of note, there is a building of heat out of Africa into Iberia at this time as a small closed upper low becomes entrained in weak easterly flow off the Canaries. GFS models 850s into the 25C bracket and surface values of 42C late next weekend in northern Spain.

On current outputs, this heat does not make it to the UK as the position of the ridge is far enough west to allow for a downstream trough into Scandinavia. However, it's worth keeping an eye out for any shift in the modelling taking the ridge further east of the Meridian. With the MJO stalling in phase 8 and the GWO looking indeterminant at the moment, the picture becomes messy but generally favourable for prolonged settled weather (just for once the stalling is in a favourable position). Any such ridge building out of Africa is going to be interesting in itself as a dome of hot air like that becomes a 'player' influencing summer patterns, especially with the Atlantic showing increasing trough tendency into August (the cold anomalies are moving into the central Atlantic region drawing any downstream ridge further west).

A couple of GFS ensembles model the hot air moving north round about the 23rd June and it will be interesting to see if the ECM suite does anything similar. Low confidence in this though at this stage although definately worth keeping an eye on.

Promising indeed!! From the Met Office too. Ave it!!! <_<

Current chat by the geeks/experts over on Netweather forums is overall remaining pretty postive this morning. Looks like that mention of unsettled by Aragorn could be a complete outlier/rogue by now.

Accuweather has always been pretty spot on when I use it.

Also, this talk of rain and clouds from the Unreliable One . Whenever I check it, it's sunny - even when I go back and check it after people have said rain here. Are they giving us all different forecasts?!

I understand some of that :D , and it looks pretty bloody good even if the more extreme 'Spanish plume' heat doesn't make it as far as the UK.
