Guidance Is Highly Consistent That The Height Gradient Associated
With The Amplified Upper-Level Trough In The Ern Conus Will Further
Relax.
A Short Wave Trough Centered Near The Nrn Rockies Early Wed
Should Dampen As It Ejects Ewd Into The Nrn Plains/Upper Ms Valley
On D4-6. Richer Low-Level Moisture Should Be Gradually Drawn Nwd
Across The Plains...But Kinematic Fields Appear To Remain Modest.
Thereafter...A More Vigorous Short Wave Trough May Advance From Swrn Canada/Pacific Nw Towards The Canadian Prairies/Far Nrn Plains Next Weekend.
But Stronger Mid-Level Flow Appears To Be Well-Removed From
The Warm Sector/Frontal Boundary In The N-Cntrl Conus.
These Setups Do Not Appear Supportive Of Higher-End Severe Coverage.
