Good point, I've not finished going through all of the entries yet - but will do so in the next 48 hours. Was a bit more tricky than I envisaged!!

Locking this for now, we'll get a winter thread up and running soon
-
Must admit I've never seen or heard of anything like this happening on the radar, and we've definitely tested it on firefox on Android without seeing this happen. It should work fine on whatever mobile browser you're using there. The only thing I can think of is that maybe your mobile is a bit low on storage space for the browser so when the map and radar images are caching it's filling the available space and stopping it from displaying.

As there was already a topic for the October 2011 heatwave, I've merged it and the thread started today together
-
This is a mixed thread, no rules in terms of which side of the 'divide' people are coming from, just needs to be based around evidence and facts rather that I'm right, you're wrong type stuff.

Bear in mind that the snow line can be 200-300m below the 0c isotherm.Whoops! You're absolutely right Yarmy. I never was very good at maths! :fool:I guess it might need the temperature to be pulled down temporarily during heavy showers!

Does sound a little bit high - I suspect it may be a positioning problem which I'll look into first thing

I'll go through all the entries today and pick out our winners

For those entering today, we'll run a mini-competition with a 1 month radar subscription as the prize. If you entered the main competition yesterday and want to enter again today feel free

Good selection of maps showing that Paul, illustrates it perfectly.
As an aside question, does that contribute to the "Shear" we hear so much about?
Yes, that's exactly what shear is - changes of wind direction at different heights. It also applies to changes of wind speed too

Forgot to add, competition closes at midnight tonight - no more entries will be accepted (for winning prizes at least) after that time.

Just for a bit of fun, we have a competition - pin the tail on the Bertha - NW Extra subscriptions for the winners

Just for a bit of fun, and thanks to Jo for coming up with it, it's competition time!
It's a bit like pin the tail on the donkey, except it's a game of pin the tail on the bertha.. Quite simply just download the blank map below, then use an image editor to mark where you think the remnants of hurricane Bertha will be centred at 12:00GMT (midday) on Sunday (free online one is available here: http://pixlr.com/editor/ ).
Then post up your marked up map with the depth in mb that you expect Bertha to be at that time.
Closest guesses on both location and depth get a 3 month NW Extra sub - if the same person gets them both then the prize will be a 12 month sub.
Good luck

Cloud quite thick here, hadn't noticed the wind direction until your post, but yes, you're right, the surface winds are from the NE, interestingly, radar shows showers heading North.
Case of storms heading against the wind?
Storms/showers/clouds are steered by the winds higher up. Can see how they veer with height on this set of maps

Latest from Michael Fish, he just loves talking about (ex) hurricanes

Problem solved - everything should be working now, although the radar may jump around a little while it all catches up.
-
We've got a server issue currently I'm afraid, or more accurately by the looks of it there's a big network issue in the datacentre which is affecting the site. We're working with our hosting co to track down the issue currently.
-
I think we need to be careful comparing the impacts of weather events and the actualities of those events. For instance, water supply infrastructure has been much improved since 1976, road infrastructure, heating in homes etc has been much improved since 1963 and so on. So if you're purely looking at the impact of the weather events in those times then the chances are those impacts will have been wider and more severe, but not in every case will the actual weather event have been any worse than one more recently.
-
Certainly pretty damp overnight for many of us, as shown on the radar totals.
As Supacell mentioned above, it's the northern half of the UK and across parts of of Ireland and Northern Ireland where the highest storm / hefty shower risk exists today. A couple of charts from our new (still in testing) NMM model.
TT index is something some of you may not be familiar with, it's a simple index which gives a rough guide to the storm risk - higher the index the more likely storms are. Anything above 45 means convection/storms are possible, above 50 and there's the risk of some more intense storms.

Can we steer this back to model related banter/moans etc now please.

HI Dallas, if you're using the GFS charts - the forecasts are based on the NMM model so won't match
-
Comparing to BF's post which uses the NMM6 it's firing the convection in slightly different places, but just subtle differences at this point which highlights the difficulty in nailing down any potential activity tomorrow.
-
My irony meter has gone into over-drive, but anyway for those who were asking about bertha there's some info in Jo's latest forecast for the week ahead.

We're just tuning an updated NMM model behind the scenes currently and thought I'd share a few shots from it to tie in with BF's very informative post above. As he said there's quite a lot of uncertainty between models currently & the new (still experimental) NMM gives a slightly different slant.
