To quote:
"The first half of April is likely to remain unsettled, with temperatures near normal and precipitation likely to be around average for most areas." The first statement in that line suggests bad weather, though the second and third suggest average conditions. Unless April habitually produces bad weather (and generally, it produces good weather as often as it does bad) that would suggest a contradiction. Nick |

Unsettled with near average temperature and rainfall is a very common British Isles situation. It's probably quite a good description of a typical British summer. -- Norman Lynagh Tideswell, Derbyshire 303m a.s.l. |

To me I've always taken "unsettled" to mean significantly above- average rainfall, and significantly below-average pressure, i.e. a series of deep lows with very active fronts and virtually no dry days, such as last November.

What will be interestin in April is that all the phases indicate the same spell except for the last one which is the same as the one just gone. (7th March on IIRC.) What happened with them recently though admittedly after a rather prolonged build up to a rather extreme earthquakes and series of lesser tremblors is that we had an anticyclone. But since the time of the phases presage goggy weather that might just be what we get. So we should be getting an inversion for the first three weeks. WHich isn't normal for April. Is it? The USGS expert at Santiago or Valparaiso or wherever, has just forecast an high probability for another large magnitude quake in the not too distant. So beware if you're there. |

Nick April showers? Unsetteld to me would just mean unsettled, IE mixed weather. Above average rainfall would be wet weather? Deep lows, active fronts - Wet and windy weather? |

Nick This thread emphasises just how difficult it is to communicate weather forecast information. The default in this country is "unsettled" weather i.e. typically the weather is very variable over relatively short periods of time. Days with rain alternated with dry days. This "typical" weather produces moderate temperatures and moderate amounts of rain. A spell of "settled" weather will, almost by definition, result in below average rainfall. "Unsettled" weather might produce above average rainfall but not necessarily so. A spell with a series of deep lows with very active fronts and virtually no dry days would probably be best described as "stormy" or "wet". -- Norman Lynagh Tideswell, Derbyshire 303m a.s.l. |

I've always made something of a, possibly incorrect, distinction in my mind between "changeable" and "unsettled". The former always seems relatively benign - the sort of dry/wet mix you describe - while "unsettled" always seems synonymous to "stormy", "wet" etc - I've always taken it to mean something *worse* than the average conditions. So November 2009 was "unsettled" while late October 2008 was merely "changeable", for instance. Not sure where I've picked that up but it's possibly through use in the past. Nick |

Nick ================ Old official definitions are that "changeable" should be used for the short term, i.e. next 48 hours or so, whereas "unsettled" should only be used for longer periods. Both mean the same thing. Will -- |

Nick Looks like the Met Office have got the right idea to avoid the "barbecue summer" problem. Express the forecast in terms that mean different things to different people. After the event, you can then explain what you meant and that the forecast was perfect. -- Graham P Davis, Bracknell, Berks., UK. E-mail: newsman not newsboy "I wear the cheese.

Both mean the same thing. I can see exactly the problem Nick has, Will - and with him, the majority of the UK population. Terms like unsettled, changeable, average, which are meaningful to professional and many amateur meteorologists, are vague to most of the population, who just don't know what they mean. Windy, rainy, snowy, sunny - even "barbecue" lol, these are fine and everyone knows what they mean. It's the in-between words that cause the problem and the Met Office would get a lot less flak if they carefully avoided them. If I may use an analogy - colours - it's like the difference between blue, red, yellow, white, black - and turquoise, mauve, purple and cyan. Some people would understand the latter better if they were described as "blue-green" etc. The Met Office really does need to say in more words than one exactly what they mean, not rely on one-word "weather types" - simply because many weather types just aren't well understood by the general population (and media!)
