================================================== ==============================
=== 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 05/03/06 to Saturday 12/03/06/ TOI (time of issue) Thursday 02/02/06 2100 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 the cold spell will be over by Tuesday in all areas. Moderate confidence in details. On Sunday a very cold northerly will bring frequent snow showers to all areas that saw most snow this week. That is, the east, west and northern fringes of the UK. Some will be heavy with drifting in strong winds. Away from the snowy areas, sunny spells with snow and hail showers in the afternoon, possibly heavy for a while and coming in a band. Moderate to severe frost after dark. On Monday snow showers will die out from the west to leave a dry and sunny cold day. Strong northerly winds easing. Frost returning in the evening, but the SW will cloud over with possibly a little rain, sleet and hill snow by midnight. On Tuesday rain, preceeded by sleet and snow on hills will spread in quickly from the west. West to southwest winds will become strong. Thaw of lying snow in all areas by evening. Turning very mild in the south later after a cold start with a lot of hill fog and drizzle, especially over thawing snow cover. Wednesday looks like being a much brighter day than Tuesday with some sunshine and just one or two showers in the north. Temperatures about averge for early March. Continued thaw of any remaining snow. More rain and wind on Wednesday night into Thursday but then turning brighter and much colder during thursday from the west. Wintry showers following the rain, mainly in western and northern areas exposed to the fresh or strong NW wind. Friday looks like starting bright and showery, but more rain and wind spreading from the SW later and turning much milder again. Outlook for the weekend and the following week. Spring arrives with temperatures reaching the mid to high teens in the south with some warm sunshine at times. Low to moderate confidence. Finally here is the Dartmoor winter walking and sledging forecast for the weekend of 4th/5th March 2006. Make the most of it as it will be the last cold and snowy weekend for a while now. Basically sunny spells and snow showers, some heavy, on both days. Max temperatures 2-5 deg C depending on altitude. Snow cover will be very variable (as it is now) with the strong sunshine melting the snow. Sledging will be iffy. However, the high moor above 480m still has plenty of snow with deep drifts over a metre, so some excellent winter walking in prospect at altitude. Combine this with the superb visibility we have had all week (out of the snow showers), it is definitely a weekend to be on Dartmoor. Well where else would you want to be :-) Will Chief Forecaster Last week's forecast below as usual ================================================== ============================== == Summary valid for Sunday 26/02/06 to Saturday 04/03/06/ TOI (time of issue) Thursday 23/02/06 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 First a few words about last week's forecast which was not up to the usual standard. Main error was that the deep low on Sunday tracked further south than expected and so rain was not as heavy nor last as long as expected. Because the rain was not as heavy it did not turn to snow at low levels or even over low hills on Dartmoor. Knock on effects were that the low-level flow was not as strong and was slower in advecting colder air from the east, hence really cold weather did not arrive till mid-week in lowland England. Also in the north some milder air got dragged over the top of the high to return today as a warm front coming in from the northeast - not picked up last thursday. So I apologise for those errors. OK, this Sunday and Monday look like being cold and bright days with plenty of sunshine around especially in the north. The sun is now strong enough to melt lying snow quickly. In southern England a strong east wind will persist, probably bringing some wintry showers, especially to Devon and Cornwall giving more snow over the moors. Staying cold with frost at night, locally severe over snow cover away from the south. On Tuesday and Wednesday the development of a cyclonic northerly regime as the high retreats to Iceland/Greenland area will bring very cold air south to all areas. Potentially then a lot of snow in exposed northern and eastern areas with drifting in the strong to gale force northerly winds. On the other hand many inland areas, such as the Midlands and large parts of southern england will stay dry with sunny spells. Severe frost in sheltered areas at night. Always the risk of troughs/polar lows coming south bringing more widespread snow, troughs more likely to affect western areas such as west Wales and Devon and Cornwall. For the rest of the week indications are that the northerly flow will ease gradually and many inland areas should stay dry and bright but very cold with frost at night, possibly some fog later too. More snow in exposed northern, eastern and some western areas. So to summarise, very high confidence for cold weather to continue all week. Moderate confidence for some very heavy snowfall with local blizzards in exposed northern and eastern areas. Low confidence for significant snow elsewhere, exposed western areas more likely than inland central parts which could stay dry throughout the week. Outlook for the following week beginning 5/3/06. Rain, preceeded by snow spreading to all areas by midweek, then mild and changeable. Low confidence in this change. Finally here is the Dartmoor winter walking and sledging forecast for the weekend of 26th/27th February 2006. Well what can I say! Excellent winter walking and sledging prospects all weekend. Snow may turn a bit soft and melt below 300m asl on Saturday but by Sunday colder air and a frosty night will ensure optimum winter conditions. Enjoy, but take care on the high plateau as wind chill will be severe. Snow tyres/chains/4WD may be necessary if driving on the more remote upland tracks. Temperatures -1 to +3 deg C depending on altitude and sunshine. Confidence high for the best weekend of the winter so far. ================================================== ============================== == Will. -- " Ah yet another day to enjoy " ------------------------------------------------------------------------------- A COL BH site in East Dartmoor at Haytor, Devon 310m asl (1017 feet). mailto: www: http://www.lyneside.demon.co.uk/Hayt...antage_Pro.htm DISCLAIMER - All views and opinions expressed by myself are personal and do not necessarily represent those of my employer. ------------------------------------------------------------------------------- |

Make the most of it as it will be the last cold and snowy weekend for a
while now. I dont understand the assumed laments as the cold snap hints at breaking down.. I hate the cold and the frosty mornings and I can't wait for the mild incursion to start. Sooner the better I think. The only thing making it slightly more bearable is the increasing strength of the sun but thats only because we actually got some fer a change with this northerly. |

The bit you quoted from was from the section aimed at people who go winter walking and enjoy sledging on Dartmoor. So the value judgement was justified as many do love winter walking and sledging as evidenced by the full car parks on Dartmoor these last couple of weekends. I know not everyone enjoys cold weather which is why I endeavour to remove value judgements from the main body of the forecast, something which other forecasts don't always do. Cheers, Will.

I do apologise after returning to your forecast I do agree I didnt fully take in your header "Finally here is the Dartmoor winter walking and sledging forecast for the weekend of 4th/5th March 2006." I just seemed to have ignored that bit for some reason and started reading the next line. Now going back and can clearly see it is intended for the Dartmoor sledger brigade. |

Felly sgrifennodd Will Hand :
a weekend to be on Dartmoor. Well where else would you want to be :-) The Cambrian mountains? There's an even snow cover here, not broken anywhere. Sledging conditions are excellent on any suitable slope. Adrian (260m asl on the western edge of the Cambrian mountains) -- Adrian Shaw ais@ Adran Cyfrifiadureg, Prifysgol Cymru, aber.
