Strong to Severe Thunderstorms Possible Sunday from the Great Plains to the Great Lakes
The upper level trough described above is forecast to track across the Central and Northern Plains on Sunday, bringing a potential for severe weather to a large area from the Southern Plains into the Great Lakes. At the surface, an area of low pressure over the Plains will track northeastward with a warm front extending to the east of the low. Scattered to widespread thunderstorms are likely to develop in the vicinity of the low and warm front. Extending to the south will be a cold front and dryline.

A Look Ahead
The area of low pressure and cold front described above will continue to intensify and move northeastward, allowing for thunderstorms from Texas to the Great Lakes on Monday. Large hail and damaging winds will be the primary hazards with these storms. Storms will continue across Texas on Tuesday as a cold front becomes stalled over Texas.

Excessive rainfall will be possible on Thursday across portions of the West Coast as a Pacific storm system moves inland. Heavy showers and perhaps a thunderstorm or two are forecast to spread inland throughout the day. The latest model guidance indicates that there will be a potential for rain amounts of 2-4 inches with locally heavier amounts in excess of 5 inches, which could allow for an increased risk of flooding and mudslides throughout the area.
