Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0126 AM CST Sun Feb 19 2017

Valid 211200Z - 221200Z


Organized severe thunderstorms are not forecast across the
contiguous United States on Tuesday.

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.
