Storm Impacting the Northwest U.S.; Fire Weather Conditions in Southern California; Severe Weather in the South

A Pacific storm is bringing areas of low elevation rain, moderate to heavy mountain snow, and high winds to the Northwest. Strong Santa Ana winds and very dry conditions are producing elevated to critical fire weather conditions in southern California. Isolated strong to severe thunderstorms are possible through early Wednesday morning across parts of northeast Texas into western Tennessee. Read More >

Showers and embedded thunderstorms will dominate much of the area today into this evening, though it may come in two waves with a brief lull around midday. Additional rainfall will be a broad 0.25 to 0.75 inch through tonight, with the lower amounts toward south central South Dakota and higher amounts east of I-29. There is still a potential for locally higher amounts, mainly in northwest Iowa, which could cause ponding water in low-lying areas.
Warm and moist air surging northward ahead of a large storm system will set the stage for periods of strong to severe storms early next week. Although a few stronger storms will be possible early Monday morning, the main severe weather risk will come Monday afternoon and evening. Note that exact details in timing and location are still uncertain. However, now is the time to check your severe weather safety plan, and please continue to monitor your local forecast for updates.
