Thanks for your honesty too Danny. I must admit had we had sub 510 DAM air mixed
in I would have gone the whole hog and confidently forecast widespread deep snow with transport and supply problems etc etc. However, the expected sub 528 DAM upper trough is well supported and looks broad enough to contain some deep cold air in depth. I acknowledge that lighter winds could mean air spending more time over the North Sea but sea temperatures are near their lowest now, nevertheless I did go for rain as the more likely option near the coast and on very low ground. Some interesting weather ahead! Will. -- "danny (west kent)" wrote in message ... Hi Will, Thanks for the forecast. I always enjoy reading your forecasts 'cause I know effort and honesty goes into it. Something I can't get on TV etc. I disagree with your forecast but I am only guessing and looking at the models, so not much expertise. From looking at all the models:- I think the Low will be too far North which will cut off the proper cold air. I think there will be *too much slack* if\when the low did get far enough south, which will lead to less cold air naturally, and lack of any precipitation if there was any real cold air. Hope I'm wrong. Best regards, Danny. ---------------------------------------------------------------------- "Will Hand" wrote in message ... ================================================== ========================== ==== === This forecast represents the *PERSONAL OPINION* of the Chief forecaster at the privately run Haytor meteorological office in Devon on how the weather may unfold next week.

Possible disruption to transport services. Very high confidence, however, that the week will be very cold with northeasterly winds setting in. On Sunday a developing low will track east across northern France and then become slow moving over Belgium and Holland before filling up by midweek and then drifting south. The low will spread rain eastwards across southern coastal counties on Sunday morning with strengthening east or northeast winds. The rain will turn heavy and persistent giving a spell of snow above 400m asl. Track uncertain, so northern edge uncertain. Later in the day as the low turns slightly northeast the rain will spread into much of SE England and the Midlands and during the evening will turn increasingly to sleet and snow on hills above about 150m asl. During the night the precipitation should drift eastwards with SW England becoming mainly dry but by Monday morning sleet and snow will be falling at low levels as temperatures fall to freezing giving a covering of snow in east and SE England. Lower risk of snowfall further west and north but certainly possible. Scotland and Northern Ireland will be cold and showery with sleet and snow on high ground. NW England showery with wintry showers on hills but possibly some rain, sleet and snow getting into NE England on Monday. Winds fresh to strong northeasterly in the south and east with some drifting snow on high ground. Moderate to fresh winds further north. On Tuesday and Wednesday moderate to fresh, locally strong, east or northeasterly winds will bring further spells of rain, sleet and snow to all areas. Rain mainly near the coast and on very low ground but inland, and especially over hills, several centimetres of snow are likely in exposed places. East and SE England seem likely to catch most snow. However, SW England (especially moors) could get some heavy snow on Wednesday as a front brushes by from the east. NW England and Scotland and Northern Ireland, brighter but still with wintry showers and some drifting on high ground. For the rest of the week the trend will be for pressure to build to the north of Britain, so staying very cold and much drier in the north with severe frost setting in at night. Further sleet and snow showers in the south and east with frost at night. Drifting of lying snow in the moderate to fresh winds in the south. Outlook for the following week with low to moderate confidence is for it to stay very cold with severe overnight frosts and further sleet and snow at times. Finally here is the Dartmoor winter walking and sledging forecast for the weekend of 18th/19th February 2006. Saturday looks like being mainly cloudy with spells of rain. Possibly some sleet and snow above 500m asl. Some sunny intervals below 300m asl. On Sunday rain with snow above 400m asl will set in during the early hours. Winds will become easterly fresh to strong with local gales on the south moor where blizzard and dangerous whiteout conditions are possible on the plateau for a time. Rain turning increasingly to snow at all levels during the day but also tending to die out from the west. Confidence moderate. Temperatures generally 1-4 deg C but falling to freezing above 300m asl by end of Sunday. Walkers are advised to get an up to date weather check before venturing out on Sunday. Sledging conditions could become good on Sunday afternoon but strong winds and heavy snow may make access difficult, also drifting could become a problem. Will Hand Chief forecaster Last week's forecast below as usual ================================================== ========================== ==== == Summary valid for Sunday 12/02/06 to Saturday 18/02/06/ TOI (time of issue) Friday 10/02/06 1930 UK local time This summary is based on a quick appraisal of the GFS, JMA, ECMWF, UKMO, FAX, and ENS (NCEP ensemble) labelled charts available from the superb http://www.wetterzentrale.de/topkarten High confidence that this week will become wet and windy in all areas for a time. Moderate confidence on turning colder later with some snow (mainly on hills) next weekend. Sunday and Monday look like turning milder as winds swing into the west spreading rain eastwards. Rain only light and patchy though in the southeast. Heavier rain spreading eastwards from the Atlantic on Tuesday and turning mild. After Tuesday and for the rest of the week a deep depression will track east to northern Scotland with secondary depressions running east towards the UK. This means that bands of quite heavy rain and strong westerly winds will sweep across all areas. Showers and brighter interludes in between. Gales likely in places on Wednesday and Thursday. Temperatures close to normal. Later in the week winds should ease and winds will turn more northwesterly and it will get colder. Remaining very showery with more rain which will turn to sleet and snow on high ground above 300m asl, even in the south. Possibly some heavy and prolonged snow in the Scottish mountains. Generally too windy and cloudy for frost next week, although later in the week temperatures will fall close to freezing in upland areas. Outlook for the following week with low to moderate confidence is for the cold and changeable weather to gradually give way to more settled conditions spreading in from the west as pressure builds again. Finally here is the Dartmoor winter walking and sledging forecast for the weekend of 11th/12th February 2006. Hope everyone remembered the suncream last Sunday while out walking. Fantastic wasn't it! This weekend looks like being mainly cloudy. Saturday mostly dry after perhaps a bit of light sleet and snow very early in the morning. Possibly some sunny intervals and light winds. Temperatures rising to near normal at 3-5 deg C (depending on altitude). On Sunday the SW wind will freshen and the cloud base will lower below the plateau as rain and drizzle sets in. Turning milder with temperatures up to 6 deg C.

Cheers Will.
I have to say that I'm more optimistic about this cold spell than previously. I've been watching the charts for a while now and the pointers all seem to be there. I'm not too sure how cold it will be though. Last Feb the snow started on the 17th, but although we had 15 days consecutive snow cover and 16 days of snow falling, it never really built up at all. I would have been happier had it been cold in Jan, but it could lead to some disappointment again. -- David Mitchell, 70m amsl, Langtoft, East Riding of Yorkshire. |

B-) As we have only had 9cm (if you include the cm that only settled on the grass this morning and lasted 3hrs) and we average 50cm a year we are due a walloping amount, maybe like last years traditional end of Feb fall? -- Cheers Dave. pam is missing e-mail |

You have got to be kidding me.
The period for Joe's forecast to materalise has been and gone Or does his forecast stretch out for months ahead ?? In that case, it's easy. There will be storms anywhere from Channel Islands to Northern England, sometime during the summer There will be Hurricanes in the Atlantic between June and November When someone makes a weather prediction, it MUST have an end date applied It's same situation with so called psychics, when they refuse to give a real date for their predictions. "There will be a big Earthquake at some point" Where? When? ..... Silence - Cause they don't want to commit themselves |

Does it mean *in* the next couple of weeks, (which is how I read it) in which case his time is almost up, or in two weeks time which is how you have read it? Col -- Bolton, Lancashire. 160m asl. |
