Welcome to the new Sheffield Weather Page. A site for the city of Sheffield South Yorkshire England. The new design is more user friendly and works across more mobile devices. Live weather via Weather display live has been discontinued however live weather is viewable via the steel gauges. I’ve moved the live data feed to my own web server due to issues with my hosting ftp server. My family has been recording Weather since 1955 and in recent years this has passed to myself. I have a large amount of data which I have published on this website and hopefully I’ll find time to add to this.

Extratropical Storm Ophelia. Updated 16/10/17 17:50pm Ophelia is now moving across North Western Ireland. Most of you will have seen the red sun due sand being funnelled north by the storm and smell of burning in some cases. This was related to the fires in Portugal. NOAA is no longer tracking the storm. The storm did end ended up being slightly west of yesterday evening predictions. Ireland has been badly hit with a  few deaths sadly and widespread power cuts.  Wales has also had bad cuts as the strongest winds transferred up the Irish sea. The picture opposit from the GFS shows the present position of Ophelia at 18:00 Monday. The strong winds still in the irish sea and west coasts of the UK. The gusts expected to be between 70 and 90mph. This can be seen in the graphics from the GFS. For Sheffield the winds will be increasing during the evening   gusting between 40 and 50 mph possibly more. The Storm continues to move away and winds moderating swinging more westerly and gusting between 35mph and 45 mph so still breezy. The dust prevented the temperatures rising as high as originally expected but very mild for October. The other feature Hurricanes and ex tropical storms bring other than warmth and strong winds is heavy rain. Here we are in luck. Most of the rain is kept well out in the sea and only hits northern Scotland later in the evening. steadily and temperatures will return to more normal values for October. Where did Hurricane Ophelia develop.? Well first of it’s a rare hurricane which started life as group of Thunderstorms several hundred miles south west of Azores. Its very rare that any such systems start life in this part of the Atlantic. Eventually these storms formed a low pressure system and tropical depression was born on the 9th of October. Although the sea waters weren’t favourable for normal development cooler air above the system allowed deep convection to continue.  By the 10th conditions indicated a possible formation of a hurricane.  On the 11th the storm started to get more organised with convective banding wrapping most of the way round the low pressure centre. By the end of the day a small eye was getting well defined. However there was uncertainty over the strength of the storm due to the lack of data. Modelling also showed for the first time that Ophelia may arrive as an powerful extra-tropical low effecting Ireland and Great Britain later. By the 12th Ophelia was a category one hurricane and NOAA advised Irish and UK public to seek guidance from the Irish and UK met office. However I would say Guidance even by the 13th was pretty poor. We often have though systems incorporating old hurricanes although very rarely as powerful as this one. The last was close one was Tropical Grace which brought damaging winds to Ireland in 2009. It was only matter of time before a more direct hit arrives and there’s still time for this one to change course. This is likely to be the last update before the storm arrives unless there’s a major change in the situation.
