SOME DISORGANIZED CONVECTION HAS DEVELOPED OVER SOUTHWESTERN SOUTH
DAKOTA AHEAD OF THE COLD FRONT THIS EVENING...AND APPEARS TO BE ON A
TRACK THAT WILL JUST SKIRT THE SOUTHERN AND EASTERN BLACK HILLS.
THE TWO PRIMARY CLUSTERS OF ACTIVITY ARE PRODUCING BRIEF MODERATE TO
HEAVY RAIN...SMALL HAIL AND FREQUENT LIGHTNING WHICH IS MAKING THE
FIRE MANAGERS A BIT JUMPY. IT IS A LITTLE EARLY TO MAKE A GOOD
JUDGEMENT ON THE FRONTAL PASSAGE FORECAST...BUT IF ANYTHING CURRENT
TIMING MIGHT BE A LITTLE FAST.  WILL MAKE SOME MINOR WORDING CHANGES
TO THE ZONES.

.UNR...NONE.
