A very active weather pattern will prevail during the next several days. A storm system currently developing over the south-central U.S. will reach the Northeast on Sunday. Rainfall could reach 1 to 3 inches , with locally higher amounts, across the eastern one-third of the U.S. In addition, locally severe thunderstorms will sweep across the South, while precipitation will end as a period of snow (on Sunday) across the interior Northeast.
By early next week, a second storm  will begin to take shape over the Great Basin. That storm will reach the central Plains by March 9, sparking wind-driven snow in parts of the north-central U.S. and severe thunderstorms in the Mid-South.
The 6- to 10-day outlook  calls for colder- and wetter-than-normal weather across much of the contiguous U.S.
