  1. Tonight I feel as we have made a significant step to northern blocking , not only do we have the artic high well in place , we also have a split vortex , which given the strength of the vortex is remarkable , what we also have hear is ridging into Scandinavia , which is very close to a undercutting scenario , no doubt in my eyes that we are close to wintry set up going by the gfs fi this evening , surprised by the negativity recently , but i think we will begin to see changes as we going to the new year.

    This is a very good chart . If we can get the energy going under the block then we have a scandi high in place, a split vortex , high lat blocking , and lots of energy coming off the Atlantic going under . Which spells a very snowy picture .

    I agree, my earlier post suggests that we are entering a real change in the pattern and the storms over the next week start that process. The artic high will be crucial regardless of where the chunk of PV sits saying that the PV could be great for the under cut scenario as you refer too.....looking forward to it

  2. Interestingly enough there is a pattern change which has just started. The forecasted temps over the next week to 10 days look to drop off to about 5-7c in the south and 4-6c further north. Although we have "zonal" conditions forecast the source of the air is from a cooler source now and will continue to do so in the reliable time frame. Predictions of white Christmas for some from the met o, interesting storms and the potential for some colder weather as we get into January via a SSW and southerly jet.......don't forget last week many were adamant that the high was set to stay......keep your eyes peeled some interesting charts to come!!!

  3. Looks like the snow signal is for shaftesbury upto evesham northwest to brecon beacons the down to neath then back through to Exeter (Exeter likely to be snow to sleet/rain) . Areas further south and east to within 3-5 miles of the coast will get light sleet and 0-3 miles of the coast will be light rain potentially freezing rain to begin with.

    the snow prone areas will look at 5-10 cm lower areas 3-5cm. The greater risk between 6pm-12am Tuesday for the heaviest ppm. will then going into Wednesday morning fizzle out to the south of our region and will remain cold.

    The likely hood of milder air pushing in on Saturday is about 60% at this stage with all models coming on board with the evolution of the transistion all slightly different with each model hence the 60%.

    There is increasing confidence that an area of low pressure will bring its attendant weather fronts in across the South West during the course of Tuesday bringing another period of potentially significant snowfall to parts of South West and Southern England.

    We have issued a % probability of disruption due to snowfall on Tuesday with the most emphasis placed on areas immediately around and South of the M4 corridor with some areas to the North of the M4 also included. Main counties of concern for the risk of 5-10cm or perhaps more are currently North Somerset, North Dorset, Bristol, Gloucestershire, Wilts and Hampshire.

    There remains some uncertainty on snow totals and the extent of the snowfall to the South and close to coastal areas, it's likely that precipitation will fall as rain and sleet initially across Devon, South Somerset, South Dorset and Coastal Hampshire, but as the cold air undercuts later it's likely to turn increasingly to snow - giving accumulations.

    The main snow line is generally in line with the M4 corridor with strongest and most persistent signals for severe disruption around the Forest of Dean, Bristol, Bath and Central/Southern Wilts into North Somerset and North Dorset.

    The Northern extent of the band could also be extended and progression East across the South Coast to affect West and East Sussex also remains a possibility.

    We'll have further updates through the course of today and tomorrow.

    I think its important to remember that Fridays Snow wasnt forecast to fall as snow on the south coast untill pretty close to the event........I for one will not be looking at that type of information with too many inconsistancies between models and positionings of LPs and PPn.

    Just to show this, the attached picture shows Christchurch (mudeford) beach
