   ...NO THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Thunderstorms are not expected Saturday.

   ...Synopsis...
   A northern-stream shortwave trough initially over the Upper Great
   Lakes is forecast to progress quickly eastward through the Northeast
   and northern Mid-Atlantic on Saturday. A low-amplitude shortwave
   trough is expected to move through the northern-stream over the
   Canadian Prairie Provinces/northern Plains and an upper low is
   forecast to move southward off the West Coast, but largely zonal
   flow is anticipated across much of the CONUS. 

   A cold front associated with the lead northern-stream shortwave will
   push southeastward through the OH Valley, Northeast, and
   Mid-Atlantic, helping to reinforce the dry and stable air mass in
   place over those regions. Low-level southerly flow is expected
   across the southern and central Plains, but moisture return will be
   limited given the previous frontal intrusion. As a result, dry and
   stable condition will prevail, and no thunderstorms are expected.
