   Day 2 Convective Outlook

   Valid 191200Z - 201200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   A few thunderstorms will be possible over a portion of the central
   and southern Rockies Tuesday afternoon and evening, far south
   Florida during the day, and parts of the central and southern
   California coast late Tuesday night.

   ...Central/Southern Rockies...
   An upper level shortwave trough will drop south/southeast over the
   central Rockies and Plains on Tuesday. Upslope flow across the
   central/southern Rockies and steepening midlevel lapse rates should
   be sufficient for isolated thunderstorms during the afternoon and
   evening as forcing for ascent increases with the approach of the
   upper wave. Instability will be limited and deep layer shear rather
   weak, precluding severe concerns.

   ...Far South Florida...
   A surface cold front will stall south of FL, but midlevel
   southwesterly flow will continue to transport moisture northward
   atop the boundary and across the peninsula. Instability will remain
   poor but could be sufficient for a few lightning strikes, especially
   near the Keys and the near-shore waters of far south Florida as a
   weak midlevel low passes from west to east across southern FL in
   broader cyclonic flow. 

   ...Central/Southern CA Coast...
   An upper trough will move inland by Wednesday morning. Steepening
   lapse rates and increasing forcing as the system moves toward the
   coast could be sufficient for a few strikes late in the forecast
   period ahead of an eastward advancing cold front.

   ...MAXIMUM RISK BY HAZARD...
   Tornado:  <2%     - None
   Wind:     <5%     - None
   Hail:     <5%     - None
