   Areas affected...portions of the Northeast

   Concerning...Severe potential...Watch unlikely 

   Valid 142020Z - 142215Z

   Probability of Watch Issuance...20 percent

   SUMMARY...A few stronger storms may produce strong to severe gusts
   and marginal hail this afternoon.

   DISCUSSION...Widely scattered shower and thunderstorm activity is
   ongoing across portions of the Northern Adirondacks in New York to
   Kennebec Valley in Maine. Through much of the morning and early
   afternoon, this area has been under mid-level cloud cover which has
   reduced daytime heating. As a result of this and ongoing showery
   activity, very marginal instability is in place. This is observed
   from the 18z ALB and GYX soundings. Though instability remains weak,
   deep layer shear around 40-45 kts may support a few stronger
   updrafts capable of strong to severe wind and marginally severe
   hail. Given the spatially limited nature of this risk, a watch is
   unlikely at this time.
