Weather
Weather is the conditions of the atmosphere at a given time and place. Weather is
described by factors such as high temperature, low temperature, chance of rain, wind
conditions, and cloud cover. There are other weather factors, but these are the five most
useful. Knowing these five things about the weather will help you to be prepared for it.
1. What is weather?
Answer:
2. What Five factors are most used to describe the weather?
Answer:
Weather Forecast
A weather forecast is a prediction of what the weather will be like on a certain day in the
near future. To make these guesses meteorologist use technology and data to make their
best possible guess. It is important to remember though that it is only a guess and the
forecast could turn out to be wrong. Because weather is incredibly hard to predict,
weather forecast usually only extend to 10 days in the future. This is what they call a 10day forecast. Forecast that are less far off in the future. The farther the forecast is in the
future the less likely it is to be accurate. For example, a forecast for 3 days from now is
more likely to be accurate then one that is for 9 days for now.

High and Low Temperature
Temperature of the weather describes how warm and how cold it is likely to get.
Temperature is therefore described with both a high and low temperature. The high
temperature is how hot it will get during the day. The low temperature is the coldest it
will get at night.
1. What does the high temperature tell you about the weather?
Answer:
2. What does the low temperature tell you about the weather?
Answer:
Chance of Rain (Precipitation)
The chance of rain is how likely it is to rain or snow on that day. The weather forecast
gives the likelihood it will rain or snow in the form of a percentage probability. For
example, it might say that there is a 40% chance of rain. The higher the percentage the
more likely it will rain in that area. Rain or snow is sometimes called precipitation.

Wind Conditions
The wind condition describes how the wind will most likely be on that particular day. It
is usually described using two factors, wind direction and wind speed.
The wind direction tells you the direction the wind will be coming from. The wind speed
tells you the average speed at which the wind will be moving. For example the forecast
