Areas affected...portions of southern Arizona

Concerning...Severe potential...Watch unlikely

Valid 012343Z - 020145Z

Probability of Watch Issuance...20 percent

SUMMARY...Thunderstorm activity will continue south and westward
through the evening with potential for strong to severe wind.

DISCUSSION...Thunderstorm activity is ongoing this afternoon along
and south of the Mogollon Rim and White Mountains in
northern/central Arizona. This activity will continue to drop
southward into the lower deserts where temperatures have crested 100
F and dew point spreads around 40-50 degrees. In addition, steep low
to mid-level lapse rates are noted with deeply mixed profiles. New
activity is forming along a southwestward moving outflow boundary
east of the Phoenix Metro. This may support a few instances of
strong to severe wind and low visibility from blowing dust this
evening.
