Forecast Discussion - Convective Outlook

   SPC AC 060042

   Day 1 Convective Outlook  
   NWS Storm Prediction Center Norman OK
   0742 PM CDT Sun Apr 05 2020

   Valid 060100Z - 061200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   The risk for severe thunderstorms is expected to remain negligible
   across the U.S. through tonight.

   ...01z Outlook Update...

   Weak high-based convection near the central and southern
   Appalachians has still been occasionally producing lightning the
   past hour or so.  However, this activity appears to be the lingering
   remnants of convection largely driven by daytime heating and
   orographic forcing, and probabilities for continuing development
   through and beyond 01Z are becoming increasingly negligible.

   Otherwise, widely scattered, generally weak thunderstorm activity
   continues beneath cold mid-level air to the east of a slowly digging
   mid-level closed low near the northern/central California coast, as
   well as around the crest of downstream ridging across parts of the
   northern Intermountain West and Rockies into the north central High
   Plains.  This may persist another hour or two, before the risk for
   thunderstorm activity becomes increasingly negligible across most
   areas.  However, weak elevated moisture return and lower/mid
   tropospheric warm advection could support a few weak thunderstorms
   overnight across parts of the eastern Dakotas into western
   Minnesota.
