Weather in USA

Weather in USA varies from not only from region to region and season to season, but also day to day and even hour to hour. Even if provinces like Alaska and Hawaii are not brought into consideration you can witness heavy drift in weather patterns in the other provinces of USA. So read through this page to know about weather in USA.
Why weather shifts in USA – Weather varies from province to province in USA because of the westerly winds sweeping across the continent of North America from the Pacific.
Best time to visit USA – As such there is no best season to travel USA. So you can plan a trip to USA in any time of the year. But the travelers are advised not to plan a trip in Alaska in the winters and Houston and Texas in the summers because of the extreme climate that these provinces experience.
Temperature of USA – Temperature in USA rises as you travel southwards and decreases as you go northwards. But the average temperature on the either coast is milder and uniform than the inlands. The Northeast provinces from Maine to Washington experiences extreme climate that is very hot in summer and bitterly cold in the winters. Florida experiences a not so warm climate because of its vicinity to the sea. The winters here are sunny and pleasant attracting thousands of tourists. The Great Plains that extends from Appalachians to the Rockies is exposed to icy Artic winds and Tornadoes are a common feature in this country. The only region of the country where winter is the wettest season is the fertile Pacific Northwest. The temperature of California is hot and dry and the mountains are always covered with snow to make it a major skiing destination. San Francisco is kept milder and colder than the surrounding district by the propensity of the Bay Area to attract sea fog, while the Los Angeles basin is prone to filling up with smog, as fog and pollution become trapped beneath a layer of warm air.
Rainfall in USA – Rainfall is minimum in the west in the Great Plains. There are mainly two patterns of rainfalls that are in the west and in the east. In the west the rainfall is controlled by topography and its proximity to the Pacific Ocean. The second pattern is observed in the East, it tends to be wetter to the south, where warmer air holds more water vapor, which largely originates over the Gulf of Mexico. In the West, it is wetter to the north, as most frontal systems stay north, especially in summer.
