Basic Understanding Of A Weather Map
Weather maps can hand drawn or computerized. Weather products are distributed to the public for their awareness.. A blue H on a weather map stands for high pressure. If your location is on the eastern side of this blue H you can expect to see partly cloudy skies and light winds. If you are on the western side of the blue H it is possible to see mostly cloudy skies along with precipitation and stronger winds.
A Red L stands for Low pressure. If your location is on the eastern side of this feature you can expect to see precipitation in the form of rain, snow, thunderstorms and severe weather. The winds will become stronger usually starting out as a southeast direction and changing to the southwest as the low pressure system gets closer. On the western side of the low pressure conditions start to improve over time and the weather becomes nice again with partly cloudy skies and cooler temps as the winds will be out of the north-northwest.
Blue lines with triangles placed on them is known as a cold front. If you are on the eastern side of this front you can expect to see thunderstorms and even snow in the winter. On the western side of this front you will see clearing skies and cooler weather as the winds are blowing from the Northwest bringing cooler air in from the north.
A red line with half circles on it is called a warm front. On the north side of this front you will see cloudy skies and rain showers. On the south of this front you will see the temperatures start to warm as the winds shift to the south which brings in warmer air.
