hey not sure if this is any help : Eleanor Porter Weather conditions As a warm front passes In a warm sector Just after a cold front passes temperature Warming suddenly increase Steadily dropping Cloud cover Stratus, sometimes cumulonimbus Cumulus Cumulus precipitation Light drizzle none Showers then clearing Wind direction Changing from (south to southeast) to … (south to southwest) Southwest West to north west pressure Levelling off increase Rising steadily
A system associated with weather conditions like lots of clouds, thunderstorms, and the possibility of tornadoes is typically a low-pressure system or a cyclone. In the United States, this kind of weather pattern is often seen with severe thunderstorms forming in association with a cold front. These conditions can also lead to the development of supercell thunderstorms that are capable of producing tornadoes.
Low pressure system, very low! Low pressure=air coming inward=lifting of air=bad weather/instability...
High
Cold fronts are typically associated with high pressure behind them, which brings cooler temperatures, clear skies, and breezy conditions. Along the front itself, there can be a rapid drop in temperature and an increase in wind speed as the colder, denser air moves in to replace the warmer, less dense air.
A stationary front occurs when a warm air mass and a cold air mass meet and do not advance due to similar air pressure. This can result in prolonged periods of clouds and precipitation along the front, creating unsettled weather conditions.
There are several different types of fronts, a warm front and a cold front. What these fronts do mainly is effect the temperature, the one that normally brings the rain is the cold front, because the cold air is colliding with the warm air already in place. When a cold front passes over, it lowers the temperature, here's a picture of what this front looks like on a weather map: When a warm front passes over, it warms the temperature, but when a cold front comes through right after that, it can spark some severe weather, here's a picture on what this front looks like on a weather map:
A low pressure system contains near surface winds.
Areas of high pressure typically bring clear skies, calm weather, and light winds. In contrast, areas of low pressure usually result in unsettled weather, including clouds, precipitation, and stronger winds.
Usually a cold or stationary front. But in summer some warm fronts will bring rain.
