4. General questions about BBC WeatherShowers can be especially hard to forecast. Their time or canada goose outlet canada goose uk online store location doesn’t have to be far out for the forecast not to be 100% correct. Showers (including hail/thunder/snow) can be very heavy or long lasting. It is also possible for showers to form into bands which can cause one area to have continuous rain.

We flag this up on the TV and video forecasts where canada goose black friday sale we can give more context, and in the text on the website. If you are making plans, either looking at a video forecast or the map on the website can be helpful to see if there are showers nearby.

This video offers further detail: Why are showers so hard to forecast?

What does % chance of precipitation (rain, snow, hail, etc) mean?

Our data supplier, MeteoGroup, uses the probability of precipitation (% chance), and this ranges from 0% (no chance at all) to 100% (it will be wet).

So what does a 20% chance of rain actually mean? It means that out of 100 situations with similar weather, canada goose discount uk it should rain on 20 of those, and not rain on 80. In a nutshell, it means that, whilst you may get some rain, canada goose black friday https://www.nationaalzweminstituuteindhoven.nl sales toronto it’s much more likely (but not certain) to stay dry.

The probabilities are given for the location chosen, and thus are valid for that location only. As MeteoGroup forecasts take advantage of hourly updates, which include real time information from radar, satellite, and nearby weather station observations, you may notice the probabilities changing in the short term (next 2 3 hours).

This gives you the chance to spot when, for example, a shower may be approaching your location, canada goose jacket outlet as the probabilities will tend to rise.

Note that when the chance of precipitation is less that 5% it will appear grey on the website. Above 5% canada goose outlet it will be blue.

How Canada Goose Online does % chance of precipitation relate canada goose factory outlet vancouver to the weather symbol?

The weather symbol is generated by canada goose outlet in chicago taking a number of weather measurements, and then working out the most likely weather type based on them. For “wet weather” symbols these measurements include the hourly rainfall amount as well as the % chance of rain (probability of precipitation).

In order to generate a wet weather symbol, there needs canada goose outlet mall to be at least some measurable rainfall expected (over 0.1mm per hour, say) and a reasonable chance of rainfall.

This means that canada goose outlet boston where very light, patchy rain or drizzle is expected, there may be occasions where the chance of seeing at least a few spots of rain is high (so a high % chance of rain), but the actual amount expected is very low (less than 0.1mm of rain in one hour).

This would be canadian goose jacket the type of weather where you feel a few spots of rain on the breeze, but it’s not even enough to dampen the roads and pavements. a cloud) but the probability of rain might be quite high.

On the other hand, in shower situations the chance of rain in an individual hour might be low in particular as it is difficult to predict long time ahead at which particular time an isolated shower will hit a particular place. When it occurs, it can be a strong short downpour and therefore the predicted amount of precipitation is reasonable high to generate a “wet” weather symbol despite a relatively low precipitation probability.

What does “feels like” canada goose careers uk temperature mean?

The temperatures in our forecasts represent the “air temperature” forecast that is, the temperature that a properly shielded thermometer would record.

However, there are factors which can lead to a day “feeling” hotter or colder than this value alone might suggest. The two main factors which cause this sensation are wind speed canada goose outlet sale toronto and humidity.

Our perception of temperature comes down to how canada goose outlet buffalo quickly, or not, our skin is cooled. In light winds and high humidity, especially with higher temperatures, any moisture on our skin will be slow to evaporate, and so the cooling will be lower.

Thus, the air may “feel” somewhat warmer than the temperature indicates. Similarly, but going the other way, a windy and dry day, especially when cold, may lead to the air “feeling” colder than the temperature may suggest.

Thus, the “feels like” temperature is designed to give an indication as to when these extra factors may combine to make the apparent temperature seem higher, canada goose clothing uk or lower, than indicated. Of course, the perception of temperature is rather subjective, so these should only be taken as broad guidelines.
