 Coming of the warm front  At the warm front  Within the warm sector  At the cold front  Within the cold sector
 Barometer – shows pressure is falling  Barometer – continues to show the pressure is falling.  No significant changes on the barometer.  Suddenly the pressure on the barometer begins to rise.  Pressure continues to rise.
 Thermometer – shows the temperature is steady  Thermometer – shows the temperature is rising. Feeling a little sticky in this heavy coat!  Still quite mild.  Time for a hat, and to button up that coat, the temperature is falling, it’s becoming chilly.  It remains cold.
 Cirrus clouds high in the sky, they begin to descend and thicken becoming altostratus.  Becomes darker, the clouds are low and cover the sky like blankets – nimbostratus.  Starting to see breaks in the cloud, a little drizzle now – nothing heavy.  Angry looking clouds, towering and grey, begin to form – cumulonimbus.  The clouds have thinned out now – some cumulus.
 No need for the umbrella yet!  Time to get out the umbrella, continuous heavy rain.  A steady breeze, nothing too uncomfortable.  Heavy rain! Is that thunder I hear?  A few showers.
 Slight increase in wind speed.  The wind is much stronger now – struggling to hold onto my umbrella.  Struggling to stay on my feet, as I’m battered by the strong winds.  Time to go home I think!
