Organized severe thunderstorms are not forecast across the contiguous United States on Tuesday. ...Synopsis... A mid-level trough over the eastern Pacific will approach the West Coast while a strong belt of mid- to high-level flow will exist from the Interior West across the north-central states and into the Great Lakes region. A series of smaller scale mid-level perturbations will translate eastward across the northern Great Basin and Northern Intermountain region. Showers and a few widely spaced thunderstorms are possible with these disturbances, especially near the CA/OR border. Farther east, a weakening and elongated mid-level trough will move across the OH Valley and a mid-level low will meander east near the LA coast. Weak instability may aid in the development of a few weak thunderstorms over the lower MS Valley. ..Smith.. 02/19/2017 $$
