Severe Weather Threat Day 2 Sun Sep 22

A Vigorous Shortwave Trough Will Eject From The Srn Great Basin
Towards The Cntrl High Plains By Early Mon. A Downstream Ridge From The Srn Plains To The Upper Midwest Will Shift Ewd And Extend From The Lower Ms Valley To The Upper Great Lakes. At The Surface...A Trough Will Become Established From The Wrn Dakotas To Ern Co Sun Afternoon.

Four Corners To The Nrn Plains...

Moisture Return Will Be Limited Downstream Of The Aforementioned
Shortwave Trough With Surface Dew Points Largely Only In The 40s To Lower 50s Sun Afternoon. Despite Meager Buoyancy...Robust Dcva Will Support Scattered To Numerous Afternoon Storms Across The Four Corners/Srn Rockies. Cooling Mid-Level Temperatures Along With Strong Deep-Layer Speed Shear Could Favor A Few Transient Supercells Producing Marginally Severe Hail/Wind.

Farther E/Ne Across The Plains...Above-Normal Surface Temperatures Should Contribute To Deeply-Mixed Thermodynamic Profiles And Isolated High-Based Storms Forming In The Late Afternoon Along The Surface Trough. These Will Likely Grow In Coverage As The Llj Strengthens Sun Evening Amidst Meridional Deep-Layer Wind Profiles. Although The Degree Of Shear Should Remain Moderate...Multicell Structures May Be Capable Of Localized Severe Wind/Hail.
