   Areas affected...Lower Deserts of Arizona

   Concerning...Severe Thunderstorm Watch 559...

   Valid 250311Z - 250445Z

   The severe weather threat for Severe Thunderstorm Watch 559
   continues.

   SUMMARY...Gusty winds remain possible with convection as it
   propagates southwest toward the lower deserts.

   DISCUSSION...Scattered convection continues to drift southwest
   toward the lower desert regions of Arizona late this evening. Much
   of this activity is struggling to maintain any appreciable intensity
   and lightning trends are gradually decreasing. Even so,
   boundary-layer lapse rates remain steep with surface temperatures
   holding above 100F where convective outflow has not modified
   conditions. Gusty winds may persist with the strongest convection
   the next few hours which may require locally extending the watch,
   but overall trends appear to be gradually decreasing.
