  1. Heads up for tomorrow folks. Storm Forecast from UKASF 00:00 Wednesday, 14th December 2011 - 23:59 Wednesday, 14th December 2011 Areas Affected: SLGT: W + NW Scotland, N Isles, NW, W + S Ireland, W Northern Ireland, S + W Wales, SW Eng, SW Mids, CenS Eng, SE Eng Synopsis: Very cold mid-levels overspreads the forecast area, with widespread deep convection, particularly close to exposed western and southern coasts. Here the best potential for significant convection is expected. Discussion: Very cold mid-levels atop relatively warm SSTs will steepen lapse rates significantly, allowing several hundred J/kg CAPE to develop, with ELTs as low as -60C (exceptionally cold!). Consequently, widespread convective showers will affect many southern and western coasts exposed to W/S winds, with various lobes of vorticity and embedded troughs pushing showers inland along distinct bands, particularly downwind of Bristol Channel. Convective gusts >55kts locally are possible, combined with >30kts LLS and >40kts DLS significantly increases the risk of tornadic development, particularly along south coasts (places notorious for scenarios like this include Bognor Regis/Selsey Bill for example). Given very cold air aloft, hail is likely in many of the showers, locally moderate in size, and in heavier downpours where the freezing level is brought to the surface, sleet and wet snow is also possible. Upper trough moves across the country late on Wednesday, continuing the risk of showers, even inland, despite the lack of insolation. http://ukasf.co.uk/storm-forecasts
  2. There's been a lot of questions and discussions regarding the great storm of 87 in the Atlantic thread. So to keep each thread on topic , I thought I'd open this for anybody to ask questions, compare and chat about the storm of 87 until their hearts content.! The Great Storm of 1987 occurred on the night of 15/16 October 1987, when an unusually strong weather system caused winds to hit much of southern England and northern France. It was the worst storm to hit England since the Great Storm of 1703[2] (284 years earlier) and was responsible for the deaths of at least 22 people in England and France combined (18 in England, at least four in France).[3] According to the Beaufort scale of wind intensities, this storm had winds of hurricane force; however, the term hurricane refers to tropical cyclones originating in the North Atlantic or North Pacific. Hurricanes have a very different wind profile and distribution to storms, and significantly higher precipitation levels. The storm was declared a rare event, expected to happen only once every several hundred years. However, the Burns' Day storm hit the United Kingdom in January 1990, less than three years later and with comparable intensity. Four or five days before the storm struck, forecasters had predicted bad weather on the following Thursday or Friday. By midweek, however, guidance from weather prediction models was somewhat equivocal. Instead of stormy weather over a considerable part of the UK, the models suggested that severe weather would reach no farther north than the English Channel and coastal parts of southern England. During the afternoon of 15 October, winds were very light over most parts of the UK. The pressure gradient was slack. A depression was drifting slowly northwards over the North Sea off eastern Scotland. A col lay over England, Wales and Ireland. Over the Bay of Biscay, a depression was developing. The first gale warnings for sea areas in the English Channel were issued at 0630 UTC on 15 October and were followed, four hours later, by warnings of severe gales. At 1200 UTC on 15 October, the depression which originated in the Bay of Biscay was centred near 46° N, 9° W and its depth was 970 mb. By 1800 UTC, it had moved north-east to about 47° N, 6° W, and deepened to 964 mb. At 2235 UTC, winds of Force 10 were forecast. By midnight, the depression was over the western English Channel, and its central pressure was 953 mb. At 0140 on 16 October, warnings of Force 11 were issued. The depression now moved rapidly north-east, filling a little as it did, reaching the Humber estuary at about 0530 UTC, by which time its central pressure was 959 mb. Dramatic increases in temperature were associated with the passage of the storm's warm front. It is now clear that for sea areas, warnings of severe weather were both timely and adequate, although forecasts for land areas left much to be desired. During the evening of 15 October, radio and TV forecasts mentioned strong winds, but indicated that heavy rain would be the main feature, rather than wind. By the time most people went to bed, exceptionally strong winds had not been mentioned in national radio and TV weather broadcasts. Warnings of severe weather had been issued, however, to various agencies and emergency authorities, including the London Fire Brigade. Perhaps the most important warning was issued by the Met Office to the Ministry of Defence at 0135 UTC, 16 October. It warned that the anticipated consequences of the storm were such that civil authorities might need to call on assistance from the military. In south-east England, where the greatest damage occurred, gusts of 70 knots or more were recorded continually for three or four consecutive hours. During this time, the wind veered from southerly to south-westerly. To the north-west of this region, there were two maxima in gust speeds, separated by a period of lower wind speeds. During the first period, the wind direction was southerly. During the latter, it was south-westerly. Damage patterns in south-east England suggested that whirlwinds accompanied the storm. http://en.wikipedia.org/wiki/Great_Storm_of_1987
  3. My Reverse psychology never worked! Parts of Bristol had thunder and lightning today , but for me, nothing again. I had everything setup, felt really positive the T&L would drift up northwards from Bristol to me. But sadly, the storms decided to tease me again and drift Eastwards grrrrr.There's a chance of thunder tomorrow again for me. :lol:
  4. Can we pleeasee keep on topic for those who may wander off. . It's still only Tuesday, remember! Let's wait until we get nearer to the time. Thanks

  7. Welcome to netweather fedupandenglish, We will certainly keep you updated here. Stay safe down there!
  8. A level 1 was issued for parts of northern UK mainly for severe winds. Storm Forecast Valid: Tue 13 Dec 2011 06:00 to Wed 14 Dec 2011 06:00 UTC Issued: Mon 12 Dec 2011 21:42 Forecaster: KOROSEC SYNOPSIS A large trough remains dominant feature across much of Europe. The main focus of interest is a rapidly developing surface cyclogenesis developing NW of UK moving east and affecting Scotland. Associated with this low, a cold front moves from the North Sea east across the central Europe. Another short-wave trough crosses Adriatic sea into S Balkans while transforming into an upper low. http://www.estofex.org/
  9. Thanks for that link.I usually use Staverton but the last report for weather observations were 3 hours 16 minutes ago. I've now lost the readings on my weather station so not to sure on the current wind speed at the moment!
  10. Latest Maximum UK windspeeds http://www.netweather.tv/index.cgi?action=current;type=maxw
  11. Ok, sorry that'll be my fault then lol. Winds are really strong here, I can't get a reading from my local weather Station it always shuts down at night.
  12. Can we please discuss buying a weather station in another thread. Thank you!
  13. Very windy now! allsorts have blown over in the garden,Can hardly open the back door due to the fierce wind. Mind,We are out in the open here and certainly not sheltered.
  14. This may help Phil, there is also a webcam on there http://www.tamarcrossings.org.uk/index.aspx?articleid=35680
  15. Must be pretty rough down Heybrook bay! Tamar Bridge reports: Plymouth (Westbound): High Winds - Vehicle Restrictions in place Saltash (Eastbound): High Winds - Vehicle Restrictions in place Updated: 12 December 11 19:41
  16. Hi Jo, this group is more an educational and fun group .The severe weather thread http://forum.netweat...cussion-autumn/ is the one to discuss present and upcoming storms!
  17. Okies, enough of about the Buoys Lol... :winky: It's starting to get worst here now! I wonder what early hours will bring I believe this is when the wind really gets going!
  18. Winds picking up here now with heavy rain . Baraometer falling quite rapidly since this afternoon,currently at 982.1 hPa
  19. Yes, great posts! good opinions. I totally agree with all so far!
  20. I'm sorry about my post just now, but I think there's something up with the Met Office and their weather warnings. I swear they keep changing their warnings. Going to keep an eye on this.............
  21. Thank you Lauren I'm using Reverse psychology at the moment. I have had a 51% chance for 3 days running now and have just checked the latest update and it's still there Lol. Now, I'm hoping I don't get one :winky:
