..DISCUSSION
A MID-LEVEL TROUGH WILL AMPLIFY WHILE TRAVERSING THE INTERIOR WEST
WEDNESDAY-FRIDAY, BEFORE EJECTING INTO THE CENTRAL AND NORTHERN
PLAINS BY THE WEEKEND. AS THE UPPER TROUGH TRAVERSES THE INTERIOR
WEST, MODEST LOW-LEVEL MOISTURE WILL ADVECT AHEAD OF IT ACROSS THE
DESERT SOUTHWEST TO THE HIGH PLAINS LATE NEXT WEEK INTO THE WEEKEND.
DESPITE STRONG FORCING ACCOMPANYING THE UPPER TROUGH, DETERMINISTIC
GUIDANCE STILL SHOWS RELATIVELY WEAK BUOYANCY ACROSS THE WARM SECTOR
OVER THE SOUTHWEST TO THE HIGH PLAINS, WITH ONLY OCCASIONAL
FAVORABLE OVERLAPS WITH STRONGER VERTICAL WIND SHEAR. SUCH SETUPS
WOULD TYPICALLY FAVOR STRONG TO ISOLATED SEVERE STORMS, AS ALSO
INDICATED BY A CONSENSUS OF AVAILABLE ML/AI CALIBRATED GUIDANCE.
