   ...Synopsis...   
   Upper pattern is expected to undergo significant amplification today   
   as a series of shortwave troughs act to deepen the upper troughing   
   across the central and eastern CONUS, and the upper ridging over the   
   western CONUS remains in place. Primary amplification will be   
   associated with a pair of phased shortwave troughs moving through   
   the western periphery of the upper troughing  over the Plains and   
   Upper Midwest.   
      
   Continental airmass associated with these shortwaves will also act   
   to reinforce the dry and stable conditions already in place across   
   the majority of the central and eastern CONUS. The only exception   
   currently is across far south FL and the FL Keys, where remaining   
   low-level moisture (i.e. dewpoints in the upper 60s) is supporting   
   modest buoyancy. This buoyancy coupled with low-level convergence in   
   the vicinity of the southeast FL coast and the Keys is fostering   
   some deeper convective cores. A few lightning flashes have recently   
   been observed near the middle Keys, and the expectation is for   
   occasional flashes to persist from the Keys into the far southeast   
   FL Coast throughout the day.   
      
   Lastly, broad ascent is anticipated across the Southeast   
   tonight/early tomorrow, resulting from a combination of lift   
   associated with the southernmost shortwave moving through upper   
   trough and lift attendant to another shortwave moving from TX into   
   the Lower MS Valley. Dry and stable low-levels will keep the region   
   free of sustained deep convection, but some forecast soundings do   
   show limited and shallow buoyancy above 700 mb. As such, there is   
   low potential for a flash or two across this region.
