How do the weather reporter know what the weather is going to be ?

Low and high pressure systems and air currents push and pull the CURRENT weather in one place into other places.  \nWhen certain types of weather conditions combine, they produce a third weather condition, such as cold air meeting humid hot air produces thunderstorms. \nWeather reporters observe existing conditions and extend their their motion to see where they will be in the future.\nAlthough it is not the most exciting thing on TV, if you watch the weather report on the news for your area, they will usually provide a 'weather in motion' map and tell WHY they are predicting what they are predicting.

Try the weather widget in Yahoo! Widgets.\nhttp://widgets.yahoo.com/\nIt gives the weather in any location. \nAlso, there is an extension for Firefox - "Forecast fox", that does the same.

it does not predict the weather....but if you have a storm moving in...the direction the storm is moving makes a difference

Both weather and quake prediction rely on taking current and past data and projecting it into the future to determine the likelihood of a particular outcome.\n\nA meteorologist will look at satellite data, temperature, atmospheric pressure and wind readings and compare them to past weather patterns to determine if the upcoming weather will be warmer, colder, wetter, etc.  The weather reports are not set in stone facts unless you are dealing with the weather of the moment or the past.  The temperatures, storm and wind predictions are merely predictions of how the weather seems to be shaping up to be.\n\nSeismologists use similar methods to provide probabilities of quake activity.  They use current ground movements, known fault structures and evidence of past seismic activity to project if a quake might occur in an area within a period of time.\n\nThe biggest difference is a matter of time scale.  Weather happens on a much shorter time scale than seismic activity.  Geologic time is measured in periods thousands of years thus making short-term predictions very difficult.  The USGS has earthquake probability numbers on their website for California for a period of 30 years (e.g. Bay Area will have a 62.5% chance of a 6.5 or greater quake sometime in the next 30 years).\n\nCompared to the geologic time scale, this is like predicting the weather in the next hour.

okay there is something really cool called KXAN 36-WeatherBug and immediately when you turn on your computer, it will show the actual temperature in your town! (Click on it and see the 7-day forecast, weather pictures sent in by users, weather updates and all sorts of great xtras) not exactly sure what website it came from.\n\n2 be honest, we got it by *accidentally* breaking our hard drive and getting really cool extras, apparently because when your computer breaks, they have 2 make sure u stay a customer!:)

look for where it asks for the zip code. changing the zip code will change the weather forcast for that vicinity.

They'll change back and forth, like weather forecasting.

Pressure changes affect the wind.  Temperature change determines whether it will rain or snow.

on yahoo search.\ntype in weather.\nitll give you a shortcut.\nthen find a place on the website where it tells you to type in your city.\ndo that.\nthen youll get the forecast.

Try googleearth ... my husband finds it excellent.  also try weather forecasting sites such as wunderground.

They measure temperature with a thermometer.\nThey measure wind speed with an anemometer.\nThey measure humidity with a hygrometer.\nThey measure the salinity with a salinometer.\nThey measure the activation with a acuator.\n\nThen they get the weather on a computer from the National Weather Service.

This site:\nhttp://www.nws.noaa.gov/ndfd/verification/index.htm\nhas a lot of information... but allows you to peruse good the forecasts were in the past.  Generally forecast skill is slowly getting better... but I really don't believe it'll ever be perfect.  When I was a kid, I wanted to be a meteorologist, but didn't really think it was more than hocus-pocus.  I can assure you there's more science than you'd ever want to know behind it... but just as any scientist... there's still mistakes made... and in our business, minor errors build into larger ones over time (something along the lines of the Butterfly Effect).  We're not always right, we are getting better, but you won't be getting perfection from us!
