Day 4-8 Convective Outlook
NWS Storm Prediction Center Norman OK
0351 AM CST Fri Nov 15 2019

Valid 181200Z - 231200Z

A large, amplified upper trough will exist over the eastern U.S.
during the D4/Mon to D5/Tue period, before ejecting across the
Northeast and Canadian Maritimes from D6/Wed to D7/Thur. Meanwhile,
another upper trough will develop over the Southwest, with the
potential for multiple waves moving into the southern Plains during
the D6/Wed to D8/Fri period.

Only a brief low-level moisture return is expected across the
southern Plains into the lower MS Valley ahead of these features as
another cold front and surface high moves south toward the Gulf
Coast. Regardless of exact timing of these shortwave troughs and the
cold front, only meager instability is likely to develop, with weak
thunderstorms possible from the desert Southwest into the southern
Plains during the D6/Wed to D8/Fri time frame. As such, severe
weather is unlikely.
