PLAINS DURING THE LATER AFTERNOON AND EVENING. SOME OF THE HEAVIER
PRECIPITATION INDICATED BY RADAR FELL FROM NEAR CHEYENNE CROSSING
AND LEAD... TOWARD GALENA AND STURGIS. EARLY THIS EVENING...A SMALL

RAPID CITY AREA.

TEMPERATURES THIS AFTERNOON PEAKED IN THE 80S TO AROUND 90...
RANGING FROM 80 DEGREES AT RAPID CITY...TO 91 DEGREES AT PHILIP.
