Severe Weather Threat Day 2 Mon Mar 25

A Broad Zone Of Cyclonic Flow Aloft Will Prevail East Of The Rockies ...As A Strong Shortwave Trough Moves From The Upper Oh/Tn Valleys Enewd Off The Mid Atlantic Coast Mon Evening...While An
Upstream Trough Amplifies Some From The Central Plains To The Tn
Valley.

Meanwhile...A Progressive Closed Low...Currently Located In The Ern Pacific /38n/143w/...Is Expected To Become An Open Wave Late Day1 As It Approaches The West Coast. This Feature Will Undergo Further Weakening Day2 As It Moves Inland Over Nrn Ca/Srn Ore After 26/00z Into A Weak Ridge In The Wrn States.

No Changes Are Needed In The Day2 Outlook As Models Maintain A
Nearly Non-Existent Potential For Tstms Across The Conus...Given A
Cool/Stable Environment.

The Exception...Though Still Less Than 10 Percent Probability...Is Located Across Nrn Ca/Srn Ore Late Mon Afternoon/Evening. Weak Destabilization...Steepening Midlevel Lapse Rates And Ascent Attendant To The Pacific Shortwave Trough Moving Into This Region May Support A Lightning Strike Or Two. However... Expected Overall Minimal Coverage Precludes The Inclusion Of A General Tstm Area.
