I think it is up to 4.1 based on the 12z GFS run http://www.maidenerleghweather.com/allsnowgraphs.php
-
from the met office... October 1926. The mean CET for the 1st to 15th was 12.41C; the mean CET for the 16th to 31st was 4.04C - a difference of 8.37C.
-
good question. does anyone know the record difference between first and second halves of a month for cet? either cold to warm or vice versa?
-
I have set up a page that looks at the HadCET so far and then looks at the GFS forecast for the rest of the month and produces a prediction of the monthly cet. as it stands it is forecasting 3.4c you can follow its progress as it updates with every GFS run every 6h at http://www.maidenerleghweather.com/allsnowgraphs.php

The lowest pressure reading recorded in the UK

will this go over the next few days? the London value may do?? -
i recently compiled this page with 500 hPA maps from the main models and also snow risk maps. http://www.maidenerleghweather.com/dam.php hope it helps someone!

pattern spotting with low res? trends are easier to see? any ideas on whether the green graph line is the best to follow?
-
thanks Paul. and out of just the graphs, is the green line usually the most accurate?
-
thanks for your help. very kind. I feel more clued up.
-
thanks. with that map I don't feel as if I'm getting as accurate data. am I? firstly I'm eyeballing where the place is, as opposed to entering a place name and secondly its not to 1 decimal place. or is it all about resolution? how easy is it to make that data available in graphical and tabular form? that would be fantastic. also just noticed that it is not for more than a day or two, rather than 16.
-
thanks, I'm guessing control is low res mean is average of low res so is low res too operational is high res and is the one to track. ps I have a net extra for this month
-
ah. I see. and the control data on the ensemble graphs are taken from low res charts.
-
thanks again. what do you mean by resolution? accuracy? if so why is there a high and low res?
-
great that makes sense. thanks. what about the operational compared to the mean? the operational is supposedly more accurate too?
-
thanks, I'm a bit of a novice. what is it then? ie how does it differ from control?
-
yes, I do mean the green line on the graph. I get the mean is the average of all the runs, the control is the line without any warm or cool adjustments but I still don't follow the green line. sorry and thanks.
-
I have looked at the help sections and also the excellent pdf guide to the ensemble graphs. many thanks for producing those. however I could only see explanations for the mean and control. what is the operational line please?
-
is the max and min the high and low runs in the ensemble?
-
i don't understand the idea of having a max (with error margin), min and average for a particular time of day? eg at 00:00 16 days in advance, the max may be 6.8(2.6) min is 5.4 (2. 8 and average is 6.8 (2.6) how do these numbers relate to each other for midnight?
-
that's EXACTLY what i was after. thanks you very much. A suggestion would be to see the predicted highs and lows for each day in one table, rather than having to click on each separate day. Many thanks!
-
thanks, I was after the raw data used to plot the ensemble graphs for a certain location. eg the data for this graph netweather.tv/index.cgi?action=ensviewer;sess=
-
I've just really got into these ensemble graphs and maps, so apologies for a rookie question. Is there somewhere that gives thee raw data for the ensemble graphical data? I am a NW extra subscriber if that gives me access at all. thanks in advance
-
pretty sure METO is 0900-0900
-
thanks, i can't see those Interitus, can you please post a link? I'm guessing it's these? http://www.metoffice.gov.uk/climate/uk/anomacts/ I was after a 1*C isotherm interval rather than 2*C, but thanks anyway.

sorted. a great site : www.tutiempo.net/en/Climate/Shawbury/09-2011/34140.htm
