Weatheronline is GFS based. 

I think with all of this apps and sites, they're relatively accurate at short range - a day or two - but after that they go downhill rapidly, especially when you have a situation like this where fine margins make a huge difference to our part of the world. 

I find weather online the most accurate for here as well. Currently shows a high of 31C on Wednesday which is entirely possible.

iPhone uses weather.com which isn't great for the UK.

Met 5 day forecast is useless. Constantly underestimates temperature. 

Just checked weatheronline and it gives a temp of 32C on Wednesday , and 30C again on Friday, 28C on Saturday.

A decent spell if it verifies. 

I'm a bit peeved by the speed at which the storms appear to be edging in by Wednesday for this part of the world, but it will certainly be an interesting week regardless of what exactly plays out IMBY, so I'm not too bothered by that just not (I will be if Wednesday does turn out to be damp and misty here in contrast to the rest of the UK though!) 

It does look likely that there will be a clean break for most from the heat between the 5th-7th, but then there looks to be an even spread of members favouring a continuation of warmth over a cooler regime taking hold, so I'm not too put-off by the current signs of northern blocking just yet. 

If the wind direction is off the Pennines or Peaks then some really good temperatures could be achieved around here and the Greater Manchester area this week. I don't think 32c is out of the question for Manchester on Wednesday. 

It is nice to see some hot weather around but it looks much better in the South and East than the North and West initially which is fairly typical for British weather of course. The likes of Manchester don't look that sunny through the first half of next week, possibly quite wet at times in fact, with warm humid days and unbearable sticky nights.

I much prefer fresher weather low 20s and sunshine if there is nothing extreme on the cards. It may improve later in the week though with the West probably seeing its best weather Thu Fri when a ridge builds back in.

Some glorious, if rather uncomfortable,summer weather on the cards further South and East - perfect Ashes weather.

Still looks odds on for a fairly quick breakdown to the initial spell and GFS wants to develop a trough over the UK as it merges low pressure systems but UKMO shows more potential for a reload, keeping the systems separate and potentially building a ridge ahead of the next incoming LP.

A bit "glass half empty" IMO.

MetO text forecasts indicate a "low likelihood" of rain Tuesday and Wednesday, and if we do get a temp of 32C, that would be pretty unusual. :-) 

Some evening thunderstorms after a hot sunny day are all part of the fun anyway! 

You could be right Jo, it may be overly pessimistic, and MetO are going for mainly fine conditions as you say but interpretation of the MO says we will only briefly get the hotter temps, Tue/Wed and those will come with a lot of cloud and high likelihood of showers. If I were planning a day out in the NW next week I would choose tomorrow or Thu but maybe will only get showers and cloud on Wed and later Fri?

22c 850s from ECM for weds. 36c I reckon for the SE

Matt Taylor on N24 earlier said 33-35C possible in southeast.

23c 850s on Saturday. 36c again I should think with sunshine in the SE

Not surprised the July record is definitely up for grabs Wednesday and Saturday.

Jaw dropping heat possible next Saturday - but at six days subject to change.  Check out the +24 uppers targeting Ian and Darren:

Personally I can see us falling well short of 30c in this neck of the woods. Mid to possibly upper 20s, but with high humidity it will feel hot. 

Still very warm and muggy for the SE day 8/9. High 20s possible

Apart from a couple of days this week,the models seem to be suggesting a north/south split for the first half of July,at least.

July this year could be like chalk and cheese between north and south.

The south could see a very warm/humid month with some blistering heat whilst the north being much cooler although still pleasant with temps around average with the odd warm day in the low to mid twenties.

Interesting times ahead!

Thats about as bad as it gets. 

I suspect that will turn out to be an outlier, let's hope so anyway.

FWIW, that ECM chart looks like a throwback to the pattern that dominated May and the first week of June!

Thank god it looks like I booked off the best possible week of the year!

And my kids in their school , they will be red hot
