5/16/06 NOW: AZ

Northeastern Maricopa County is under severe t-storm warning as of 3:57pm. Scottsdale, New River and Fountain Hills, just outside the Phoenix metro area, were first warned on, but the line of storms appear to be heading (slowly) in a southwesterly direction and affecting other areas.

Winds can exceed 60mph with these storms, lofting sand and dust. Lightning chasers may have to contend with low visibility and strong wind gusts while driving.

Some of the cells were showing 65dbz at one point.

Lightning tracker is showing significant CG activity. One useful map is here:

Note...this is not monsoon. The North American monsoon begins to affect Arizona usually by early July, with the official start in the Phoenix area declared when dewpoints reach 55 degrees for three consecutive days.

These storms may die down quickly after sunset. However, conditions might warrant one last check for any possible activity in the Central Deserts later (referring to the area near I8 and west of I10 in the south central deserts of Arizona).
 
I only got a sprinkle and 40 to 50 MPH gusts in Queen Creek. Nice dust storm and some lightening...
