..DISCUSSION
WITHIN THE BASE OF A HIGHLY AMPLIFIED LARGE-SCALE TROUGH OVER THE
WEST, A MIDLEVEL VORTICITY MAXIMUM WILL PHASE WITH STEEP MIDLEVEL
LAPSE RATES OVER SOUTHWESTERN AZ TODAY. WHILE WEAK BUOYANCY WILL
DEVELOP ATOP A DRY LOW-LEVEL AIR MASS (INVERTED-V-TYPE SOUNDING),
CONVECTION SHOULD REMAIN TOO WEAK FOR LIGHTNING OWING TO THE LIMITED
MOISTURE. ELSEWHERE, A COLD/DRY AIR MASS WILL PRECLUDE THUNDERSTORM
POTENTIAL ACROSS THE CONUS.
