   Areas affected...Northern Maine

   Concerning...Severe potential...Watch unlikely 

   Valid 091748Z - 091915Z

   Probability of Watch Issuance...20 percent

   SUMMARY...A very isolated severe hail/wind risk may continue across
   far northern Maine through early/mid-afternoon, mainly across
   Aroostook County.

   DISCUSSION...An isolated right-moving supercell is ongoing across
   Aroostook County, roughly 30-35 miles north of the Houlton
   area/I-95. This storm is within environment by a relatively
   long/straight hodographs with 40+ kt effective shear, with
   instability maximized where storms are ongoing across northern
   Maine, in vicinity of a differential heating zone where morning
   clouds are abating. Current thinking is these isolated
   storms/supercell are probably near peak intensity, but the potential
   for isolated severe hail/wind may persist across far northeast Maine
   through around mid-afternoon as storms drift southeastward.
