   Areas affected...Parts of southeast AZ

   Concerning...Severe potential...Watch unlikely 

   Valid 060447Z - 060615Z

   Probability of Watch Issuance...20 percent

   SUMMARY...A threat for strong to severe gusts may continue through
   late evening, before an expected weakening trend overnight.

   DISCUSSION...Vigorous convection has persisted this evening across
   southeast AZ, while the northern portion of a large MCS and related
   outflow over northeast Sonora has moved northwest across the border.
   Moderate buoyancy remains in areas that have not been convectively
   overturned, though CINH is beginning to increase with the onset of
   nocturnal cooling. While convection should eventually subside
   overnight, the presence of multiple surging outflows may allow for a
   continuation of deep convection and a threat of strong to severe
   gusts through late evening.
