A stubborn upper-level low pressure system will bring cooler, unsettled weather to California early this week while dotting the Great Basin with showers and thunderstorms through midweek.
This low pressure center or pocket of cool air aloft, currently spinning just west of San Francisco, has already brought a bout of cooler air into Southern California.
That is more welcome news for firefighters who are currently in the process of containing the Springs fire.
This system will continue to bring showers and thunderstorms across the Central Valley, the Sierras and the Great Basin. This can ruin outdoor activities across Fresno, Medford and Salt Lake City.
Showers and thunderstorms will continue through most of the day across the region with the exception of along the coast. Drier air is expected to move across coastal California, limiting showers to the morning only.
Denver, Colorado Springs, and Cheyenne could get in on the thunderstorm activity by Tuesday afternoon.
As this pocket of cold air slides eastward it will keep unsettled weather in place over the Intermountain West through Wednesday and Thursday. While it certainly won't rain all the time, residents and vacationers will want to keep an eye to the sky.
Have a backup plan in case thunderstorms threaten and make sure there is a sheltered, indoor location nearby.
While a lot of the Intermountain West is suffering from severe to extreme drought, the scattered rains will be welcome news. However, if the downpours are heavy enough, flash flooding could occur as the water will just run off of the very dry grounds.
This system will eventually move out into the southern Plains late this week, with a new round of severe weather expected across parts of Texas, Oklahoma, Arkansas, and Louisiana.
AccuWeather.com will have more information on the late week severe weather over the next few days.
