   Concerning...Snow Squall=20   
      
   Valid 312342Z - 010415Z   
      
   SUMMARY...A snow squall may develop in the next couple of hours, and   
   progress across portions of the Ohio Valley into the northern   
   Appalachians through evening. A sudden onset of moderate to heavy   
   snow and 15-30 mph sustained northwesterly surface winds (with   
   higher gusts) will create hazardous driving conditions, including   
   reduced visibility.   
      
   DISCUSSION...A pronounced, strongly positively tilted mid-level   
   trough is amplifying across the Great Lakes and is progressing   
   toward the Northeast. A 100-130 kt 500-300 mb jet streak is pivoting   
   around the upper trough and is poised to overspread the northern   
   Appalachians over the next few hours. The approach of this jet   
   streak will dynamically enhance low-level lift along a   
   southeastward-moving surface cold front that is currently draped   
   over southern ON to Lower MI/southern WI. This aforementioned lift   
   will force a low-topped snow band along the surface cold front, amid   
   a sub-freezing troposphere in the next 1-3 hours.   
      
   While the synoptic pattern is generally favorable for snow squalls,   
   steep low-level lapse rates and accompanying instability is   
   currently lacking ahead of the cold front. Nonetheless, strong   
   925-700 mb CAA accompanying the mid/upper-level jet streak will aid   
   in the steepening of low-level lapse rates behind the cold frontal   
   snow band, which may result in just enough destabilization (albeit   
   very scant) to support a leading-line low-level circulation. Should   
   a snow squall develop, a sudden onset of stronger northwesterly flow   
   (at least 15-30 mph, with higher gusts) may accompany portions of   
   the leading line, along with moderate to potentially heavy snowfall   
   rates. Brief periods of appreciably reduced visibility may occur in   
   stronger portions of the snow band.
