Currently in Lincoln: Temp: 23c Dew point: 15c Pressure: 1009 steady Cloud cover: 6/8 Cirrus & Cirrostratus Visibility: 40km Wind: SW force 4

In a nuclear explosion or volcanic eruption the "cloud" can extend well into the stratosphere because it is a lot warmer than the surrounding air even through the temperature inversion of the tropopause. Condensed water clouds at that level are made of ice crystals and can never penetrate the temperature inversion of the tropopause. Mine was a pretty basic answer that could probably be expanded upon in some way, however.

CET 14.5c for me.

One things for sure, it's much cooler here this July than last year. Nearly 0.5c colder. The CET cyrrebtky stands at 15.1c, a bit lower than last year, no doubt will rise a bit by the end of the month with the slightly above average temps predicted.

The radar is not good for my area. Put LN1 into the netweather radar and you can see there are intense blobs all around here but the shield around here means we are getting nothing. It is not actually raining at all.

Long range forecast Summer '08 and early autumn '08: OK I don't claim to use any scientific methods but let's see anywy July 2008 Generally about average temperatures, wet at times, warm at others while slightly unsettled and showery, this remaining through to the early 4th week, then brief high pressure from the east will develop, giving some settled days with average to slightly above average temperatures CET: 16.0c August 2008 Starting slightly settled seeing highest temperatures in the first week. However, becoming quickly unsettled with north westerly winds dominating, showery with longer outbreaks of heavy rain at times and depressions tracking one by one over the UK. Much cooler than normal. CET: 14.3c Before any one jumps on me let's say nobody really "knows" anything when it comes to Long Range Forecasting. Doing it this way is no less accurate than using scientific methods in my opinion these days, that will soon change of course, but there's my forecast, you can take it at face value and just see what happens, like we all have to do. Some of the most meticulously thought out scientifically based forecasts for the long term turn out to be the most dramatically incorrect of all!

16.0

LOL I was not being serious... jeez. My point is NOBODY KNOWS. I was being ironic if you didn't notice.

I will revise my estimation I think. 28.5C on 17th July, LHR. Just over the max reached temperature for May which I think was 28.2c somewhere.

Summer discussion eh? Well, summer 2009 is the heatwave of the century, with 40c finally reached in the UK. 2008: A dreary, cool washout with more flooding and cool temperatures. Just be patient. It's only another year until Summer 2009.

14.1

Forget june it looks like after a dry May so far (no rain at all in many places) theres going to be 4 inches over the bank holiday weekend. Enjoy.

30.1c London Weather Centre 17th July.

We failed to reach 25C in Lincoln. Hopefully June will do it.

I wonder if it will happen here on saturday. Tomorrow should be a good warm day again in the east and we got close today at 23.0C.

Well it probably won't be happening here until summer time.

Rapid cooldown here. 12c compared to the max of 20.5.

I think 24c might be reached but possibly not 25 before the beginning of next week. Low pressure looks set to interrupt on friday brining cold temperatures and rain looking at the 06z update, which will make for a pooor weekend. Thursday would have the highest chance of 25c this week but really I think about that time next week is likely to topple 25.

The humidity is very low in the UK at 20c but is much higher at the same temperature in spain, so it would feel warmer at 20c there. It is extremely dry here at 20c relative humidity is just 38%.

Yes it is largely about the dewpoint and the "feel" of the heat can be calculated using the "heat index" scale. I was in Rome in June and July last year and it does still feel very hot in the shade, but it definately felt like dry heat and not humid at all. Portugal is another place I have frequented in the summer months and that also is pretty dry heat. If anyone could ever want some where where you can hardly breath and get exhausted by lifting a finger there are tropical places where temperature might "only" reach 85-95*F but the relative humidity is around 60-70% at that temp with dewpoints around 75-85*F. I don't think that can be imagined unless one were to go there. I think, the canary islands get a lot of fog and cool breezes from the sea that moves in and that is why when that stuff rolls across the islands it feels cool.

Sooooooooo. what's the news You couldn't do it could you lol

Still a "hot" 13.7 degreees C here at 1 hundred hours 5th. And a "humid" dewpoint of 12.2 degrees. phew what a scorcher.

Can anyone give us the 911 on tomorrows chance in England? Should be some CAPE around again

How I wish I was there with you, we got our first thunder in Lincoln yesterday but it was weak and dying here, your storms will knock the crap out of anything here! Enjoy all the fine food!

I'm amazed at the hail you got from that storm, it looked pretty severe! Technically if it is more than 2cm in diameter its a severe thunderstorm. Over where I was it must have been strengthening because it was giving light 1cm hail here and was mostly in the updraft stage, before dropping its load properly. It had a great structure to it when north of here though! Good pictures of the gust front.
