This series of hints goes over processes that can cause dramatic changes in the weather. This writing discusses fronts. Fronts can result in a dramatic change in the weather. The passage of a cold or warm front can cause a dramatic shift in wind, temperature, humidity and weather. With adequate moisture, precipitation is common along the frontal boundary. The most noticeable weather change with a frontal passage is temperature. The fastest temperature changes tend to occur with cold fronts. Temperature can drop 10s of degrees within an hour or two. In some cases, there can be more than a 20 degree F temperature drop in just minutes. The gusty winds can bring the wind chill down also thus the weather outside feels significantly colder than before frontal passage. Strong rain bands can develop on and near the frontal boundary. The weather can go from mild and partly cloudy to windy with heavy rain as the front passes. The strong wind can blow in sheets of heavy rain. The intense lifting that the front can produce helps lead to the big change in weather. A warm front passage is typically not as violent as a cold front passage but significant weather changes can still occur. The weather can go from damp and cold to warm and partly sunny in the matter of minutes as the front passes. Strong storms can also occur near the warm front boundary due to the lifting that the warm front provides. |
