   OCCURRING ON A MORE ISOLATED BASIS IN SOUTHWEST WY. THESE STORMS ARE
   LIKELY BE AIDED BY A WEAK/NORTHEASTWARD-MOVING MID LEVEL IMPULSE
   THAT IS EMBEDDED WITH MODERATELY STRONG SOUTHWESTERLIES ALOFT AS PER
   THE GRAND JUNCTION WSR-88D AND RUC DERIVED WINDS /AS MUCH AS 35-40
   KT AT 500 MB/. GIVEN TOWERING CU ACROSS MUCH OF SOUTHERN/EASTERN UT
   INTO SOUTHWEST WY/WESTERN CO...AND THE PRESENCE OF A RELATIVELY
   MOIST AIRMASS WITH PRECIPITABLE WATER ON THE ORDER OF 0.8-1.0
   INCHES...THE AFOREMENTIONED IMPULSE/VERTICAL SHEAR SHOULD FAVOR AN
   INCREASE OF RELATIVELY FAST/NORTH-NORTHEASTWARD MOVING STORMS...WITH
   THE STRONGEST CAPABLE OF SEVERE HAIL/WIND THIS AFTERNOON.
