![]() ================================================== ============================== === 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. The Chief forecaster will take no responsibility whatsoever for any actions arising from its use. It is provided freely in the spirit of freedom and the great love for meteorology that we personally enjoy and wish to share freely with others. ================================================== ============================== === Summary valid for Sunday 19/02/06 to Saturday 25/02/06/ TOI (time of issue) Thursday 16/02/06 2000 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 Moderate confidence that this week will see the first widespread snowfall of the winter in England and Wales. 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.

The situation seems oddly similar to exactly the same point in time last year when snow started to fall on the 22nd Feb and continued through to the start of March. Then it wasn't *quite* cold enough for significant accumulations. -- Jonathan Stott Canterbury Weather: http://www.canterburyweather.co.uk/ Reverse my e-mail address to reply by e-mail |

As I said in the forecast my confidence is moderate. Make your own mind up how Haytor meteorological office has been doing recently. All I do is say it how I see it.

Thanks Will.
From the silence yesterday I was beginning to think that I was the only one that thought we were in for some snow. As far as I can see tonight, the models are going for at least a week long cold spell - with amazing agreement. Its not often weve seen that. Who says it doesnt snow a week after the USA :-) Even Ian Currie is predicting a White Christmas 2006 already! Phil |
