   Areas affected...Portions of Central/Southern Arizona

   Concerning...Severe potential...Watch unlikely 

   Valid 090001Z - 090130Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Isolated strong to severe wind gusts remain possible into
   the early evening in parts of central/southern Arizona.

   DISCUSSION...A recent observed wind gust from the Tucson airport of
   61 kts continues to suggest the potential for strong to severe wind
   gusts exists in parts of central/southern Arizona. Outflow is also
   becoming more evident on KIWA radar imagery. This outflow is
   generally moving toward the Phoenix metro area. Strong to severe
   wind gusts are possible as this occurs. Additional thunderstorms may
   also develop as these outflow propagate into the lower deserts and
   potentially interact with one another. These storms could produce
   equally strong downburst winds given the very steep low-level lapse
   rates.
