   Day 3 Convective Outlook

   0212 AM CST Sat Jan 02 2021

   Valid 041200Z - 051200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   A few low-topped thunderstorms will be possible Monday across the
   coastal Pacific Northwest and into parts of northern California.

   ...Synopsis...
   The upper-air pattern will remain amplified, yet progressive on
   Monday, with an upper trough over the Southeast and a secondary wave
   moving eastward across the Great Lakes. This will reinforce high
   pressure from the Plains into the Southeast, providing stability
   with continued offshore flow.

   To the west, significant height falls will occur during the day from
   northern CA into the Pacific Northwest as an amplified shortwave
   trough moves ashore around 00Z. Cool air aloft combined with lift
   from a cold front may result in isolated to scattered low-topped
   showers and thunderstorms, with the greatest lightning flash density
   likely offshore. Low-level lapse rates over land will be relatively
   poor with little to no heating due to increasing clouds and
   precipitation. Due to the weak instability, severe weather is not
   anticipated.
