   Day 2 Convective Outlook  
   NWS Storm Prediction Center Norman OK
   1203 PM CDT Tue Mar 31 2020

   Valid 011200Z - 021200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   General thunderstorms are forecast across portions of the contiguous
   United States on Wednesday. A few storms may produce small hail over
   Nebraska.

   ...Synopsis...
   An upper trough will exit the East Coast, with high pressure
   bringing cooler and drier conditions to the eastern CONUS behind a
   cold front. This front will affect portions of south FL early in the
   day with scattered showers, but will quickly move east.

   To the west, multiple waves will rotate around an upper trough over
   the Northwest, with a leading wave ejecting north across the Dakotas
   during the day. Little if any instability will be present with this
   feature. By evening, warm advection will increase over the northern
   Plains with a nocturnal southerly low-level jet. The presence of
   cool midlevel temperatures and a plume of 50s F surface dewpoints
   upstream will support widely-scattered thunderstorms, mainly across
   NE. While the stronger storms may produce small hail, severe weather
   is not expected.

   Elsewhere, daytime heating along with very cold temperatures aloft
   beneath the upper trough will result in isolated thunderstorms over
   northern OR and ID, possibly producing graupel.
